Study: Advanced reactors a good fit for Puerto Rico

An article published over the weekend in the Tacoma News Tribune reports that the Benton Public Utility District in Kennewick, Wash., is saying no to more wind farms. Even though utilities are moving to decarbonize the grid, a report from the Benton PUD says that more wind farms “will contribute very little to keeping the regional power grid reliable and will not help Benton PUD solve our seasonal energy deficit problems.”

The final safety evaluation report for NuScale Power’s small modular reactor design has been issued, completing the design’s technical review and approval, the Nuclear Regulatory Commission announced on August 28.

The NRC will now prepare a rulemaking to certify the NuScale design. Full certification, if granted by the commissioners following the staff’s recommendation, will allow a utility to reference the design when applying for a combined license to build and operate a nuclear power plant.

The NuScale design is the first SMR to receive NRC design approval.

All energy sources, including small modular reactors, are being considered to meet Puerto Rico’s energy needs, U.S. Coast Guard Rear Admiral Peter J. Brown said on July 15 during the second day of PR-Grid Virtual, a three-day online conference on Puerto Rico’s energy grid. Brown’s comments were quickly circulated on Twitter by people who are already working to make nuclear power a reality for Puerto Rico, including members of the Nuclear Alternative Project (NAP), a non-profit organization of Puerto Rican engineers in the nuclear industry.

The House Appropriations Committee held its full committee markup of the Energy and Water Development bill on July 13. (The Bill Report provides a more detailed funding breakdown.) The final bill passed the committee by a party line vote of 30-21. No schedule for Floor consideration of the bill has been set, but it is likely to happen next week or the week after.

The ANS Young Members Group and the Gateway for Accelerated Innovation in Nuclear (GAIN) on June 18 presented a webinar on the rapidly developing prospects for advanced nuclear in Puerto Rico. Behind those bright prospects is the Nuclear Alternative Project (NAP), which led a Department of Energy–funded study on the feasibility of using small advanced reactors to meet the island’s power needs.

The government of Canada’s Saskatchewan province has unveiled plans to establish an office to coordinate nuclear policy and program work. The office, dubbed the Nuclear Secretariat, will have as its primary mission to develop and execute a strategic plan to deploy small modular reactors, according to a June 24 press release. The secretariat will be housed within the Climate Change and Adaptation Division of Saskatchewan’s Ministry of Environment.

A report published last week by Energy Systems Catapult, a U.K.-based clean energy nonprofit, concludes that adding double-digit gigawatts of new nuclear is a “low-regrets option” for the United Kingdom as it strives to achieve net-zero carbon emissions by 2050. (Legislation establishing the 2050 target date was signed in June of last year, making the United Kingdom the first of the world’s major economic powers to take that step.) The report also stresses, however, that costs for new nuclear must decrease significantly for the technology to meet its potential.

The U.S. International Development Finance Corporation (DFC) has initiated a 30-day public notice and comment period on a proposed change to the agency’s Environmental and Social Policy and Procedures that would allow it to consider support for nuclear power projects, according to a June 10 press release. Currently, DFC is specifically prohibited from offering support for such projects.

Global First Power (GFP), Ultra Safe Nuclear Corporation (USNC), and Ontario Power Generation (OPG) have announced the formation of a joint venture to construct, own, and operate USNC’s Micro Modular Reactor (MMR) at Canadian Nuclear Laboratories’ Chalk River Laboratories site in Ontario. The venture, known as the Global First Power Limited Partnership, is owned equally by OPG and USNC-Power, the Canadian subsidiary of USNC.

The University of Tennessee (UT) and the Tennessee Valley Authority (TVA) signed a memorandum of understanding on April 7 to evaluate the development of a new generation of cost-effective advanced nuclear reactors, such as small modular reactors (SMR), at TVA’s 935-acre Clinch River Nuclear Site in Roane County, Tenn.
