UK unveils financial terms it offered Hitachi


Greg Clark, the UK's secretary of state for Business, Energy and Industrial Strategy (BEIS), today spoke “candidly” about the unprecedented financial terms offered to Hitachi ahead of the company’s decision to suspend its new nuclear power plant project.

Japan’s Hitachi said it will halt work on its UK subsidiary's plan to build two new nuclear power plants "from the viewpoint of its economic rationality as a private enterprise". It added, however, that "further time is needed to develop a financial structure" for the Horizon project.


Established in 2009 and acquired by Hitachi in November 2012, Horizon Nuclear Power aimed to provide at least 5.4 GWe of new capacity across two sites - Wylfa Newydd, which is on the Isle of Anglesey, and Oldbury-on-Severn, in south Gloucestershire - by deploying Hitachi-GE UK advanced boiling reactors (UK ABWRs).


Hitachi’s decision comes just two months after Japan’s Toshiba Corp announced it was withdrawing from its nuclear new-build project in the UK and winding up NuGeneration, which had planned to build a nuclear power plant of up to 3.8 GWe gross capacity at the Moorside site in West Cumbria, using AP1000 nuclear reactor technology provided by Westinghouse.



Three offers


Clark gave an oral statement to the House of Commons concerning the UK's nuclear future following Hitachi's announcement. The GBP20 billion (USD26 billion) Wylfa Newydd plant was expected to be operational by the mid-2020s and create 9000 jobs in the area. Clark described the commercially sensitive details of the negotiations BEIS and Hitachi had held since last June.


Firstly, the government was willing to consider taking a one-third equity stake in the project, alongside investment from Hitachi and government of Japan agencies and other strategic partners. Secondly, the government was willing to consider providing all the required debt financing to complete construction. Thirdly, it agreed to consider providing a Contract for Difference to the project with a strike price expected to be no more GBP75 per megawatt hour.


"I hope the House would agree that this is a significant and generous package of potential support that goes beyond what any government has been willing to consider in the past. Despite this potential investment, and strong support from the government of Japan, Hitachi have reached the view that the project still posed too great a commercial challenge, particularly given their desire to deconsolidate the project from their balance sheet and the likely level of return on their investment."


He added: "The government continues to believe that nuclear has an important role to play, but critically it must represent good value for the taxpayer and the consumer. I believe the package of support that we were prepared to consider was the limit of what could be justified in this instance."


He stressed that Hitachi has made clear that while it is suspending project development at this stage, it wishes to continue discussions with the government on bringing forward new nuclear projects at both Wylfa and Oldbury and it intends to work closely with the company in the weeks and months ahead.


"If new nuclear is to be successful in a more competitive energy market - which I very much believe it can be - it is clear that we need to consider a new approach to financing future projects, including those at Sizewell and Bradwell. As I initially set out in June, we are therefore reviewing the viability of a Regulated Asset Base model and assessing whether it can offer value for money for consumers and taxpayers. I can confirm to the House that we intend to publish our assessment of this method by the summer at the latest," Clark said.



More time needed


Announcing suspension of the project, the Tokyo-headquartered company said today: "Since the acquisition of Horizon Nuclear Power, Hitachi has set the following three points as the main criteria for business continuation and reviewed the Horizon project from the viewpoint of its economic rationality: securing reasonable returns as a private enterprise; realising a financial structure on the premise of making the Horizon project off balance sheet; limiting an investment amount to an acceptable range as a private enterprise.


"Unfortunately, despite the best efforts of everyone involved, the parties have not been able to reach an agreement to the satisfaction of all concerned. As a result, Hitachi has decided to suspend the project at this time from the viewpoint of its economic rationality as a private enterprise, as it is now clear that further time is needed to develop a financial structure for the Horizon Project and the conditions for building and operating the nuclear power stations."


Agneta Rising, director general of World Nuclear Association said: "We urge the UK government to bring forward fresh proposals for a stable financing framework to enable the construction of new UK nuclear projects that will supply electricity competitively."

US nuclear innovation act becomes law


Bipartisan legislation modernising US nuclear regulation and supporting the establishment of a licensing framework for next-generation advanced reactors has been signed by US President Donald Trump. The Nuclear Energy Innovation and Modernisation Act (NEIMA) became law on 14 January.

As well as directing the Nuclear Regulatory Commission (NRC) to modify the licensing process for commercial advanced nuclear reactor facilities, the bill establishes new transparency and accountability measures to the regulator's budget and fee programmes, and caps fees for existing reactors. It also directs the NRC to look at ways of improving the efficiency of uranium licensing, including investigating the safety and feasibility of extending uranium recovery licences from ten to 20 years' duration, and directs the Department of Energy to issue at least every ten years a long-term plan detailing the management of its excess uranium inventories.


Maria Korsnick, president and CEO of the US Nuclear Energy Institute, described NEIMA as a "significant, positive step" toward the reform of the NRC's fee collection process. "This legislation establishes a more equitable and transparent funding structure which will benefit all operating reactors and future licensees," she said. "The bill also reaffirms Congress’s support for nuclear innovation by working to establish an efficient and stable regulatory structure that is prepared to license the advanced reactors of the future."


Marilyn Kray, president-elect of the American Nuclear Society, said the passage of the legislation was a "big win" for the nation and its nuclear community. "By reforming outdated laws, NRC will now be able to invest more freely in advanced nuclear R&D and licensing activities. This in turn will accelerate deployment of cutting-edge American nuclear systems and better prepare the next generation of nuclear engineers and technologists," she said.


The bill was introduced in 2017 by Senator John Barrasso of Wyoming. It was approved by Congress on 21 December by 361 votes to 10, having been passed by the Senate the previous day.


NEIMA is one of several bipartisan bills that support advanced nuclear innovation considered by the 115th US Congress, which ended on 2 January. These are: the Nuclear Energy Innovation Capabilities Act (NEICA); the Nuclear Energy Leadership Act; the Nuclear Utilisation of Keynote Energy Act; the Advanced Nuclear Fuel Availability Act; and legislation to expedite so-called part 810 approvals, which are needed for the export of technology, equipment and components. NEICA, which supports the deployment of advanced reactors and also directs the DOE to develop a reactor-based fast neutron source for the testing of advanced reactor fuels and materials, was signed into law in October.

Wolsong 1 simulator to be repurposed for use at unit 3


Korea Hydro and Nuclear Power (KHNP) has contracted L3 MAPPS to repurpose the full-scope simulator for unit 1 of its Wolsong nuclear power plant for training operators at Wolsong unit 3. Wolsong 1 is scheduled to be shut down by 2022.

Simulators are a vital piece of equipment for training plant operators, both at the start of their careers and for their continuing training. They replicate control room panels and help train students in reactor operations under normal conditions and in emergency situations.


Canada-based L3 MAPPS said the project to convert the Wolsong 1 simulator for use at Wolsong 3 will begin immediately.


The Wolsong 3 full-scope simulator, like that of Wolsong 1, will use L3's PC/Windows-based graphical simulation tools for the plant models and instructor station. All the plant systems will be simulated, including the reactor, nuclear steam supply systems, balance of plant systems, electrical systems, and instrumentation and control systems. The Wolsong 3 simulator models will be based on planned adjustments to the Wolsong 1 simulation that have already been developed, validated and maintained in L3's Orchid simulation environment.


As part of the conversion, the Wolsong 1 simulator's full replica main control room panels will be returned to Canada to be upgraded to accurately represent unit 3's main control room.


In addition, the Wolsong 3 simulator will include severe accident simulation capabilities and will be equipped with two- and three-dimensional animated, interactive visualisations of the reactor vessel and containment building.


Michael Chatlani, vice president of marketing and sales for L3 MAPPS Power Systems and Simulation, said: "L3 MAPPS is pleased KHNP decided to convert the Wolsong 1 simulator contracted in 2016 to become the operator training platform for Wolsong 3. We were near completion of the Wolsong 1 simulator, so it is extremely gratifying that all the hard work that went into the simulator will be leveraged for Wolsong 3."


The converted simulator is expected to be in service by the third quarter of 2020.


The Wolsong site in Gyeongju, North Gyeongsang Province, houses four 700 MWe Candu 6 pressurised heavy water reactors. L-3 MAPPS supplied the full-scope operator training simulators for all four units.


KHNP announced last June that Wolsong 1, which began generating electricity in 1983, will be retired prior to the expiration of its operating licence in 2022. The company said its decision was based on the "uncertain economic viability" of its continued operation and recent low operating performance. Wolsong 3 began commercial operation in July 1998.

Further US grant for Framatome EATF development


The Volgodonsk branch of AEM Technology has completed the first stage of installation of the control assembly of the MBIR multipurpose sodium-cooled fast neutron research reactor. MBIR is under construction at the site of the Research Institute of Atomic Reactors (NIIAR) at Dmitrovgrad, which is in Russia's Ulyanovsk region.

Vyacheslav Pershukov, Rosatom's special representative for international and scientific projects, witnessed the milestone, which AEM Technology, a subsidiary of Rosatom's Atomenergomash, announced today.


"This is unique equipment, a unique enterprise, and Atommash is of course up to the task," Pershukov said. "The task is quite complex for the whole of Rosatom owing to the large volume of international orders. Its uniqueness means MBIR is not a priority for us from the commerce perspective, but rather from the reputation perspective," he said.


Andrey Nikipelov, general director of Atomenergomash, noted the thinness of the MBIR casing - 25-50 mm - with a diameter of 4 metres, which contrasts with that of a VVER-1200 reactor which is 300 mm. This means it is challenging to alter the equipment geometry during processing. he said.


The MBIR project will next involve hydrotesting and the assembly of a protective casing. Then the second stage of the control assembly installation will be completed with all the internal components.


Igor Kotov, general director of AEM Technology said: "You could say that, at our site today, a new page has been written in the history of nuclear energy. MBIR is a fundamentally new product and all the operations the AEM Technology team is carrying out are being carried out for the first time."


Atomenergomash is the main equipment supplier of the MBIR reactor. Its Volgodonsk branch is manufacturing 14 products, including housing elements and supporting structures.


The MBIR is a 150 MWt, sodium-cooled fast reactor and will have a design life of up to 50 years. It will be a multi-loop research reactor capable of testing lead, lead-bismuth and gas coolants, and running on MOX (mixed uranium and plutonium oxide) fuel. NIIAR intends to set up on-site closed fuel cycle facilities for the MBIR, using pyrochemical reprocessing it has developed at pilot scale.


The MBIR project is to be open to foreign collaboration, in connection with the International Atomic Energy Agency's International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO).


The MBIR will replace the BOR-60 experimental fast reactor that started operations at NIIAR's site in 1969.

Further US grant for Framatome EATF development


Framatome has received a USD49 million, 28-month grant from the US Department of Energy (DOE) to accelerate the development and commercialisation of enhanced accident tolerant fuel (EATF).

Accident-tolerant fuel (ATF) designs enhance performance during normal operations at nuclear power plants and provide operators with more time to respond in the event of loss of active cooling.


Framatome is developing both near- and long-term EATF solutions for all types of nuclear power plants. The integrated near-term solution incorporates both chromia-enhanced pellets and chromium-coated cladding. These fuel pellets and clad coating have characteristics that, when combined with other recent advancements, will deliver value to the existing fleet of reactors through a variety of measures, including operator flexibility and fuel efficiency.


Chromium coating is a feature of the ATF design that Framatome has been developing for several years as part of the DOE's Enhanced Accident-Tolerant Fuel programme, which aims to commercialise ATF by 2025. This work also builds on several years of collaboration with its European partners, CEA and EDF in France, as well as the Gösgen nuclear power plant in Switzerland.


The addition of chromium coating to the fuel's existing alloy cladding offers advantages, including improved resistance to oxidation at high temperatures, reduced hydrogen generation in accident conditions, and increased wear and debris resistance in normal operation, according to Framatome.


In addition to this near-term work, Framatome continues research on a silicon carbide-based cladding with even greater potential. The ongoing research and development of these state-of-the-art materials and related manufacturing processes are critical to safe, clean and more efficient power generation.


Framatome said the funds from this DOE grant build on a USD10 million, two-year grant that it received from the DOE in 2016, and will contribute to the advancement of laboratory testing and data collection, as well as irradiation test programmes. Additionally, the grant will support further development of advanced manufacturing processes and the acceleration of long-term EATF solutions, including silicon carbide fuel cladding.


"EATF designs represent the next evolution in technologies that will support today's and tomorrow's nuclear reactors and unlock value in Framatome's products and the existing nuclear fleet," said Bob Freeman, vice president, Contracts and Services, North America, Framatome Fuel Commercial and Customer Center. "With the support of DOE, Congress and our industry partners, we are ahead of schedule in making this fuel technology available to nuclear power plants so that they can continue to provide clean, efficient electricity."


In July 2017, it was announced that four test lead assemblies of Framatome fuel featuring chromia-doped fuel pellets and chromium-coated fuel cladding will be loaded into unit 2 of the Vogtle plant in Georgia early this year.


Framatome is one of three companies - the others are Global Nuclear Fuel (GNF) and Westinghouse - working with the DOE to commercialise their ATF concepts by 2025. The DOE's ATF programme was launched following the 2011 Fukushima Daiichi accident and aims to demonstrate performance by inserting ATF technology into a commercial reactor by 2022, and bring advanced fuel concepts to market by 2025. This accelerated timeframe is critical if ATFs are to benefit the current fleet of operating nuclear reactors, many of which are currently licensed to operate into the 2030s.

Nuclear remains Belgium’s main power source


Belgium’s nuclear power plant produced 48% of total electricity in 2018, according to the Brussels-based Belgian Nuclear Forum. Fossil fuels accounted for 40%, wind for 7% and solar energy for 5%.

However, maintenance outages and unplanned shutdowns meant that the nuclear share decreased compared with previous years. The nuclear share in 2017 was around 49.8%.

Belgium’s seven power reactors – three at Tihange nuclear plant near Liege and four at Doel near Antwerp – produced 27.3TWh of electricity in 2018.  Six of the seven units were closed in 2018 for maintenance. Three nuclear plants remain offline. Tihange 2 is still closed because of concrete degradation issues and Doel 1&2 are offline following a leak at Doel 1. Tihange 1, Tihange 3, Doel 3 and Doel 4 are operating.

Russia’s Novovoronezh 4 restarted after upgrades



Cooling towers at Novovoronezh (Credit: Rosenergoatom)Unit 4 of Russia’s Novovoronezh nuclear plant, a VVER-440 reactor was brought to 100% of the rated capacity on 10 January after an extended overhaul and equipment modernisation programme to extended its operating life another 15 years.  

"In the large-scale retrofit, resources were used from unit 3 (now closed), and fundamentally new safety systems were created.  As a result, unit 4 will meet the most modern requirements, despite the fact that it was designed in the 1960s”, said deputy chief engineer Andrei Meremyanin. Novovoronezh 4, which was commissioned in 1972, now has a 60-year operating life.

As well as Novovoronezh 3&4, Russia has four VVER-440 units operating at its Kola nuclear plant. Kola 1 has also undergone modernisation and life extension. Also, 29 VVER-440 units have been built worldwide in Armenia, Bulgaria, Hungary, Germany, the Czech Republic, Slovakia, Ukraine and Finland, some of which are now closed.

 

Novovoronezh was the first nuclear plant in Russia with VVER-type reactors (light-water-cooled pressurised reactors). Three reactors are the leading prototypes for later mass-produced power reactors. Novovoronezh 1 (a VVER-210) was commissioned in 1964, Novovoronezh 2 (a VVER-365)  in 1969, Novovoronezh 3 in 1971, Novovoronezh 4 in 1972, and Novovoronezh 5 (a VVER-1000) in 1980. Units 1&2 were shut down in 1984 and 1990 for decommissioning, while Novovoronezh 3 retired in 2016.  Unit 1 the Novovoronezh-II plant, also known as Novovoronezh 6, (a VVER-1200) was commissioned in February  2017 and a second VVER-1200 is nearing completion.

Wyoming uranium projects look to the future


The Lost Creek in situ leach (ISL) uranium project has produced a cumulative 2.7 million pounds U3O8 (1039 tU) since beginning operations in 2013 and could ramp production up within six months, Ur-Energy said yesterday. Meanwhile, Uranium Energy Corp has announced a new consolidated mineral resource estimate for the Reno Creek project which it says makes it the largest permitted, pre-construction ISL uranium project in the USA.

Lost Creek produced 286,400 pounds of dried and drummed U3O8 in 2018, Ur-Energy said in its quarterly operational results. It "stands ready" to increase production at Lost Creek and to begin development activities at Shirley Basin, should uranium pricing continue to improve, or after a "successful" outcome to the US Department of Commerce's (DOC) ongoing Section 232 investigation.


The company reduced production levels from 2016 in response to a "persistently weak" uranium market, but has remained operationally ready to increase production to pre‐2016 levels, or higher, when market conditions warrant the further development of the Lost Creel's fully‐permitted Mine Unit 2 (MU2).


"Lost Creek operations could increase production rates in as little as six months following a go decision simply by developing additional header houses within MU2," the company said, adding that no significant capital expenditure would be needed in order to increase production. "The Lost Creek plant has been very well maintained and is fully ready to receive additional flows for increased production when warranted," it said.


It is also continuing with permitting and licensing the Shirley Basin project and is working with the State of Wyoming to secure the licences and permits needed to begin staged construction and development of the project this year, with full operation as early as mid‐2020. Construction and development activities at Shirley Basin would follow the ramp-up of Lost Creek, it said.


The DOC launched its investigation into possible threats from uranium imports to national security in July last year, after Ur-Energy Inc and Energy Fuels Inc filed a petition that January calling for such an investigation under Section 232 of the Trade Expansion Act of 1962. The petitioners called for a quota to limit imports of uranium into the USA, effectively reserving 25% of the US market for US uranium production, and also suggested that federal utilities and agencies be required to buy US uranium. A comment period on the investigation closed in September.


The DOC is expected to submit a report of findings and recommendations of any proposed remedy to the US president in the second half of 2019, after which the president will have up to 90 days to act on the report.



Resource update for Reno Creek


Uranium Energy Corp (UEC) said today that its newly released updated mineral resources for Reno Creek rank the project as the largest permitted, pre-construction ISL uranium project in the USA, with a measured and indicated mineral resource estimate of 26 million pounds U3O8 at an average grade of 0.041% U3O8. Inferred mineral resources are estimated at 1.49 million pounds U3O8 at 0.039%. The NI 43-101-compliant estimate consolidates for the first time major mineralised trends within the Eastern Pumpkin Buttes District of Wyoming's Powder River Basin.


UEC completed the acquisition of the North Reno Creek project in May last year, having previously acquired the fully permitted Reno Creek project in August 2017.


"For decades, the Reno Creek uranium district has been unable to reach its full potential due to fractured ownership," UEC President and CEO Amir Adnani said today. "Through a string of accretive acquisitions over the past 24 months, UEC has successfully consolidated the key project areas, clearing the path for this substantial new resource, with the benefit of being covered under our existing production permit."


Wyoming in September became a US Nuclear Regulatory Commission Agreement State, giving it the authority to regulate in situ recovery facilities in Wyoming. This will streamline the process to include the North Reno Creek resources under the existing Reno Creek permit, as UEC will now only be required to work with state regulators to secure the necessary permit revisions, the company said.

NuScale SMR to be considered for use in Jordan


A joint feasibility study on the deployment of NuScale's small modular reactor in Jordan will be carried out through a memorandum of understanding signed between NuScale Power and the Jordan Atomic Energy Commission (JAEC).

Announcing the MoU today, NuScale said the feasibility study will "inform JAEC's decision on moving forward with the project as part of Jordan's planned deployment of nuclear power plants".


"As Jordan considers its energy future, I'm confident that the unmatched resiliency and safety features of NuScale's SMR technology make us the ideal partner on the Kingdom's nuclear power goals," said NuScale Power Chairman and CEO John Hopkins. "We look forward to using the agreement to showcase our SMR's unique capabilities, cost benefits and flexibility, all of which demonstrate what a game-changer this technology will be for Jordan."


"NuScale is at the forefront of US SMR technology," said Khaled Toukan, chairman of JAEC. "We look forward to this collaboration to assess the viability and potential for deployment of NuScale SMR technology in Jordan."


NuScale's self-contained SMR design houses the reactor core, pressuriser and steam generator inside a single containment vessel. A single module can generate 50 MWe (gross) of electricity and at just under 25 metres in length, 4.6 metres in diameter and weighing 450 tonnes, incorporates simple, redundant, diverse, and independent safety features, the company says. A power plant could include up to 12 modules to produce as much as 720 MWe (gross).


NuScale's SMR is undergoing design certification review by the US Nuclear Regulatory Commission (NRC), the first and so far only SMR to do so. The NRC completed the first phase of its review in April last year, and the regulator is scheduled to complete its safety evaluation report in August 2020. NuScale expects the application to be approved by the commission the following month.


Utah Associated Municipal Power Systems plans the development of a 12-module demonstration NuScale plant at a site at the Idaho National Laboratory, with operation expected by 2027. The US Department of Energy in December signed an MoU on the use of power from two of the 12 modules.


In November, NuScale Power signed an MoU with Bruce Power to develop a business case to introduce its SMR technology to the Canadian market.


NuScale said it has "seen considerable interest in its SMR technology in regions of the world, like the Middle East, where fossil fuels are the source of heat and electricity for desalination".


Jordan's Committee for Nuclear Strategy in 2007 set out a programme for nuclear power to provide 30% of electricity by 2030, plus some for export.


Jordan, which relies on imports to meet over 95% of its energy needs, had planned to build a nuclear power plant, comprising two 1000 MWe units, in the Amra region, about 70 kilometres east of Amman. The first unit was expected to in operation by 2021 and a second one by 2025. Jordan selected Russia as the preferred bidder for the plant, into which Russia was also to make a significant investment. However, Jordan scrapped the project, citing costs.


In November 2013, JAEC said it would build several small reactors of about 180 MWe capacity. In March 2017, an agreement between JAEC and Saudi Arabia's King Abdullah City for Atomic and Renewable Energy was signed for a feasibility study on construction of two SMRs in Jordan. In November that year, JAEC signed an MoU with Rolls-Royce to conduct a feasibility study for the construction of an SMR. Later in the same month, JAEC signed an MoU with X-energy to assess the US company's SMR.

Vermont Yankee sale completed


Entergy Corporation has completed the sale of Entergy Nuclear Vermont Yankee to subsidiaries of NorthStar Group Services, which will decommission the Vermont Yankee Nuclear Power Station site.

Entergy described the sale as the first of its kind in the nuclear power industry, involving a permanent ownership and licence transfer to a company that is to perform decommissioning and site restoration. The single-unit boiling water reactor ceased operations in December 2014 after 42 years of operation, and Entergy in November 2016 announced the sale of the plant to NorthStar for accelerated decommissioning.


The US Nuclear Regulatory Commission last October approved the transfer of Vermont Yankee's operating licences to NorthStar, and the Vermont Public Utility Commission issued an order approving the sale in December.


The NorthStar decommissioning team includes Orano USA, who will provide reactor vessel segmentation and used fuel management support; Waste Control Specialists, providing waste management, packaging, transport and disposal; and Burns & McDonnell, who will provide engineering and regulatory support. NorthStar has said it will start decontamination and dismantling work at Vermont Yankee by 2021 and complete decommissioning and site restoration by 2030, with the exception of the Independent Spent Fuel Storage Installation into which all the plant's used fuel has now been transferred. This is 45 years sooner than under Entergy's original decommissioning schedule for the plant.


The transaction "closed on terms consistent with the companies’ previously disclosed financial commitments and assurances", the companies said. The pre-tax book charge to Entergy's earnings is expected to be consistent with previous estimates, and will be recorded in fourth-quarter results for 2018. It will be considered a special item and excluded from operational results, the company said.
