Canada unveils ambitious plan for SMRs

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.”

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 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.

Bulgaria’s Kozloduy nuclear plant

Portland, Ore.–based NuScale Power has signed a memorandum of understanding with Kozloduy Nuclear Power Plant–New Build Plc (KNPP-NB) to discuss the possible deployment of NuScale’s small modular reactor technology at Bulgaria’s Kozloduy site. KNPP-NB was established in 2012 to commission new nuclear power capacity at Kozloduy.

Specifics: Under the MOU, NuScale will support KNPP-NB as it analyzes the suitability of NuScale’s SMRs for Kozloduy, located in northwest Bulgaria. The analysis will include the development of a project time line “with milestone deliverables for a feasibility study” and a project-specific cost estimate, as well as engineering, planning, licensing, and other activities, according to a February 17 NuScale press release.

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.

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.

The U.S. Trade and Development Agency (USTDA) has awarded a grant worth an undisclosed amount to Romania’s nuclear energy authority, Societatea Nationala Nuclearelectrica (SNN), for technical assistance to support the development of small modular reactors in that country, the agency announced on January 14.

The grant will be used to identify a short list of SMR-suitable sites, assess SMR technology options, and develop site-specific licensing roadmaps. SNN has selected Chicago-based Sargent & Lundy to carry out the assistance.

The site of the Oyster Creek Nuclear Generating Station in Lacey Township, N.J., could be the location for Holtec International’s SMR-160 small modular reactor, according to an AP News story published last week.

ARDP investment: Holtec received $147.5 million in Advanced Reactor Demonstration Program funding to demonstrate its SMR design. Company spokesperson Joe Delmar said, “As part of our application to the Department of Energy for its advanced reactor demonstration program, we expressed interest in possibly locating an SMR-160 small modular reactor at the Oyster Creek decommissioning site in the future. This concept is only preliminary and something we would likely discuss with Lacey Township and the community if plans to locate (the reactor) at Oyster Creek evolve.”
