Bulgaria to evaluate NuScale SMRs for Kozloduy

Nuclear power could produce as much as one-third of the United Kingdom’s clean hydrogen needs by 2050, posits the Hydrogen Roadmap, a 12-page report recently approved by the Nuclear Industry Council (NIC) and released last week by the Nuclear Industry Association (NIA).

The NIC, co-chaired by the British government’s minister for business, energy, and clean growth, and the chairman of the NIA, sets strategic priorities for government-industry collaboration to promote nuclear power in the United Kingdom.

The road to net zero: The report outlines how large-scale and small modular reactors could produce both the power and the heat necessary to produce emissions-free, or “green,” hydrogen. Existing large-scale reactors, it says, could produce green hydrogen today at scale through electrolysis, as could the next generation of gigawatt-scale reactors. Also, according to the report, SMRs, the first unit of which could be deployed within the next 10 years, could unlock possibilities for green hydrogen production near industrial clusters.

A new survey exploring the attitudes of Canadians toward climate change and their expectations and level of support for government intervention to tackle the issue finds that 86 percent believe that Canada should invest in clean technologies, including renewables and nuclear energy.

The survey, conducted by research and strategy firm Abacus Data between January 29 and February 3, was commissioned by the Canadian Nuclear Association (CNA).

CNA says: “It’s clear there is strong support for the government to implement a mix of solutions to address the [climate change] challenge, including investing in renewables and clean nuclear technologies,” stated John Gorman, CNA president and chief executive officer, in a February 18 press release. “We continue to see that the more understanding Canadians have, the more they support zero-emissions nuclear technologies to help reach our net zero 2050 goal. This includes investment in small modular reactors, which Canadians believe bring value to replace carbon-based fuels with clean electricity, decarbonize high-emissions industries, and transition remote communities away from reliance on diesel.”

A Montana Senate committee last week passed a joint resolution calling for the creation of a legislative panel to study the feasibility of replacing the coal-fired units at the state’s Colstrip power plant with advanced small modular reactors.

Two of Colstrip’s four coal boilers were permanently closed in January 2020, and most energy-sector observers expect the remaining two units to be retired within the next few years, given coal’s declining prospects in states such as Washington, which has passed legislation banning utilities from using coal power after 2025.

The resolution, known as SJ3, also calls on the panel to evaluate current Montana regulations that need revision in order to enable the construction and operation of advanced nuclear reactors. The study would need to be concluded before September 15, 2022.

The Canadian province of New Brunswick has awarded C$20 million (about $15.7 million) to ARC Clean Energy Canada (ARC Canada) to support the development of the proposed ARC-100 advanced small modular reactor. The premier of New Brunswick, Blaine Higgs, announced the award during his state of the province address on February 10.

ARC Canada, headquartered in Saint John, New Brunswick, is a subsidiary of U.S.-based ARC Clean Energy, formerly known as Advanced Reactor Concepts. The company’s ARC-100 is a 100-MWe integrated sodium-cooled fast reactor that uses a metallic uranium alloy fuel. Based on Argonne National Laboratory’s Experimental Breeder Reactor-II, the reactor is designed to operate for 20-plus years without refueling.

In October 2019, ARC Canada announced that it had completed the first phase of the Canadian Nuclear Safety Commission’s (CNSC) vendor design review. (While the phase-one assessment provides detailed feedback regarding a vendor’s understanding of the CNSC’s requirements for a nuclear power plant in Canada, it does not certify the design or license the reactor.)

The Tennessee Valley Authority is seeking public comment on its notice of intent to prepare a programmatic environmental impact statement (PEIS) on proposed actions for an advanced nuclear reactor technology park at the 935-acre Clinch River site near Oak Ridge, Tenn. The notice, published yesterday, is also expected to appear in this Friday’s Federal Register.

The consideration of a new nuclear facility at the Clinch River site “supports TVA’s mission statement and is another way to assess how to serve the people of the Tennessee Valley,” according to TVA.

Your turn: TVA is requesting comments on the scope of the PEIS, alternatives being considered (including a no-action alternative), and environmental issues. Comments are due by March 19 and can be submitted online, via email, or by mail to J. Taylor Cates, NEPA Specialist, 1101 Market Street, BR 2C-C, Chattanooga, TN 37402.

TVA recommends giving feedback electronically, due to COVID-19 teleworking restrictions.

A preliminary study conducted by the nuclear waste storage and disposal startup company Deep Isolation found that Estonia’s geology is capable of safely hosting a deep horizontal borehole repository for radioactive waste from advanced nuclear reactors.

The study, commissioned by advanced reactor deployment company Fermi Energia, found no fundamental geologic limitations to disposing of nuclear waste in deep horizontal boreholes, according to Deep Isolation. In addition, the study noted that a wide range of locations could be demonstrated to comply with International Atomic Energy Agency regulations for geologic disposal.

The findings: Results of the study, which was conducted in collaboration with Estonian geologic and drilling company Engineering Bureau STEIGER, will be presented as part of Fermi Energia’s one-day conference on small modular reactors, "New Generation Nuclear Energy in Estonia," on February 9. Registration for the event is available online.

The loosely connected plug keeping the United Kingdom’s Wylfa Newydd nuclear new-build project alive has been officially pulled.

Horizon Nuclear Power, the Hitachi subsidiary that remained involved in the project following its parent company’s pullout in September 2020, has formally withdrawn its application for a development consent order (DCO) regarding the proposed nuclear plant. (DCOs are required for large infrastructure projects in the United Kingdom to move forward.) The facility was to be sited adjacent to the decommissioned Wylfa reactors, on the island of Anglesey, off the northwest coast of Wales.

A decision on the DCO application, under review by the U.K. Planning Inspectorate since 2018, was expected by April 30, after a series of successful requests for extensions from Duncan Hawthorne, Horizon’s chief executive officer, who had cited “discussions with third parties that have expressed an interest in progressing with the development” of Wylfa Newydd.

Armenia plans to extend the operational life of Unit 2 at Metsamor (also matter-of-factly known as the Armenian nuclear power plant) beyond 2026 and has not abandoned plans to construct a new reactor, the Armenian news agency ARKA reported on January 14, citing the country’s new cabinet-approved strategy for energy sector development through 2040. (The Armenian government in 2014 decided to extend Unit 2’s service life to 2026.)

The nuclear advantage: “Having a nuclear power plant in the energy system will allow Armenia to diversify its energy resources, avoid increasing the country’s dependence on imported natural gas, as well as cut the volume of emissions,” the strategy document states, according to ARKA. “The government remains committed to its policy of having a nuclear power plant in the country’s generating capacity. In this context, it should be noted that the option of maximally extending the operating life of the nuclear power plant is a guarantee of the development of the system at the lowest cost.”

Bulgaria has become the 34th member of the Paris-based OECD Nuclear Energy Agency (NEA). With its several decades of experience operating VVER units, Bulgaria will reinforce the NEA’s capacity to address matters related to pressurized water reactor technologies and their operational characteristics, according to the NEA on January 4.

In addition, the NEA said that it will support Bulgaria’s efforts in technical and policy areas, including work to address nuclear skills capacity building, the development and application of nuclear data and simulation codes, and issues related to radioactive waste management, decommissioning, and nuclear economics.

British hybrid clean energy company Shearwater Energy announced on January 15 that it is joining with U.S.-based NuScale Power to develop a hybrid project using wind energy and small modular reactor technology to produce power and green hydrogen.

According to news reports, the two companies signed a memorandum of understanding to collaborate on an initial project, which could be sited at the now-decommissioned Wylfa nuclear power station on the island of Anglesey, off the northwestern coast of Wales. No land agreements have been reached, however.
