The Nuclear Regulatory Commission has approved a request from the Tennessee Valley Authority to increase the generating capacity of Unit 2 at the Watts Bar nuclear power plant by 1.4 percent, according to an October 27 press release from the agency. TVA submitted its application for the power uprate on October 10, 2019, and the NRC issued the required license amendment on October 21.

The power uprate, which TVA intends to implement by mid-December, will increase Unit 2’s generating capacity from approximately 1,223 MWe to 1,240 MWe.

“The NRC staff determined that TVA could safely increase the reactor’s output, primarily through more accurate means of measuring feedwater flow,” the press release stated, adding, “NRC staff also reviewed the TVA evaluations demonstrating that the plant’s design can safely handle the increased power level.”

Rosenergoatom, the electric power division of Russia’s state-owned nuclear power corporation Rosatom, announced on October 23 that Leningrad II-2 has been connected to the grid. The unit is one of two Generation III+ VVER-1200 pressurized water reactors at the Leningrad nuclear plant.

The reactor will replace Leningrad I-2, a 925-MWe RBMK-1000 light-water–cooled graphite-moderated reactor that will permanently cease operation at the end of 2020 after 45 years of service. Fuel loading at Leningrad II-2 began in July, and initial criticality was achieved in August. Following the trial operation, the unit will be shut down for an additional equipment inspection by a state commission before being put into commercial operation early next year, according to Rosenergoatom.

Rising

Agneta Rising, outgoing director general of the World Nuclear Association, wrote in an October 27 World Nuclear News article that nuclear power is an essential part of the climate change solution, even if it is not part of the conversation in the European Union. “In many ways, the future of nuclear energy is much brighter than it has been for many years. We are evermore recognized and valued for the unique services that nuclear energy offers humanity, and I am immensely proud to have served and led our industry through these exciting times," said Rising in a farewell message that recapped her time as WNA director general.

Advanced reactor developers see potential markets for reactors in a range of sizes that offer clean, reliable, flexible, and cost-competitive power.

Canada has invested Can$20 million in Terrestrial Energy’s 195-MW Integral Molten Salt Reactor through the Ministry of Innovation, Science and Industry, the company announced on October 15. In accepting the investment, Terrestrial Energy, which is based in Oakville, Ontario, has committed to creating and maintaining 186 jobs and creating 52 co-op positions nationally. In addition, Terrestrial Energy is spending at least $91.5 million on research and development. According to the company, the funds will assist with the completion of a key pre-licensing milestone with the Canadian Nuclear Safety Commission.

Two days earlier, Terrestrial Energy USA and Centrus Energy announced that they had signed a memorandum of understanding to evaluate the logistical, regulatory, and transportation requirements to establish a fuel supply for Integral Molten Salt Reactor power plants, which would use standard-assay low-enriched uranium at an enrichment level less than 5 percent.

In testimony filed last week with the Georgia Public Service Commission, Georgia Power and Southern Nuclear acknowledge that the “aggressive” target dates set in July for some of the Vogtle construction project’s upcoming milestones have had to be pushed back by a few months. At the same time, however, the companies continue to express confidence in being able to meet the regulatory-approved commercial start dates for the new reactors—November 2021 for Unit 3 and November 2022 for Unit 4.

The testimony was filed in support of Georgia Power’s Twenty-third Semi-annual Vogtle Construction Monitoring Report, released in August, which covers the period from January 1 to June 30, 2020.

The United States in the past few weeks has signed civil nuclear agreements with Romania and Poland, and now a third European nation can be added to the list: Bulgaria.

Unit 5 at China National Nuclear Corporation’s (CNNC) Fuqing nuclear power plant has achieved initial criticality, becoming the very first Hualong One reactor to reach that milestone, the company announced on October 22. If all goes according to schedule, the unit will enter commercial operation later this year.

Fuel loading for Unit 5 began on September 4, following the issuance of the reactor’s operating license by China’s Ministry of Ecology and Environment. The loading of 177 sets of fuel assemblies was completed on September 10.

Also known as the HPR1000, the Hualong One is a Chinese-designed, 1,000-MWe Generation III pressurized water reactor. Fuqing-5’s twin HPR1000, Fuqing-6, is scheduled to start contributing power to the grid next year.

Located in China’s Fujian Province, Fuqing also houses four 1,000-MWe CPR-1000 PWRs, with commercial start dates of November 2014, October 2015, October 2016, and September 2017.

The U.S. International Development Finance Corporation (DFC) has signed a letter of intent to support NuScale Power in the development of 2,500 megawatts of nuclear energy in South Africa, according to an October 16 DFC press release.

Ratliff

Harris

When Floyd Harris began working at Duke Energy’s Brunswick nuclear plant about 24 years ago as a radiation protection technician, robotics and remote monitoring were considered tools for radiation protection and nothing more. Now, teams from across the site, including engineering, maintenance, and operations, rely on the system of robots and cameras Harris is responsible for. “If you want to put those technologies under one umbrella,” says Harris, who now holds the title of nuclear station scientist, “it would be monitoring plant conditions.”

That monitoring is critical to effective plant maintenance. As Plant Manager Jay Ratliff explains, the goal is to “find a problem before it finds us” and ensure safety and reliability. Nuclear News Staff Writer Susan Gallier talked with Ratliff and Harris about how robotics and remote systems are deployed to meet those goals.

At Brunswick, which hosts GE-designed boiling water reactors in Southport, N.C., ingenuity and hard work have produced a novel remote dosimetry turnstile to control access to high-radiation areas, an extensive network to handle data from monitoring cameras, rapid fleetwide access to camera feeds to support collaboration, and new applications for robots and drones.

Entergy Corporation’s Palisades nuclear power plant returned to service on October 21, following the completion of the Covert, Mich., facility’s final refueling and maintenance outage, which began on August 30.

The company invested more than $86.5 million during the outage, according to Entergy. The plant’s 600 full-time nuclear professionals worked with approximately 800 supplemental workers to replace reactor fuel and to inspect and upgrade hundreds of pipes, pumps, electrical components, and other equipment.

Murkowski

Luria

Sen. Lisa Murkowski (R., Alaska), chairman of the Senate Energy and Natural Resources Committee, and Rep. Elaine Luria (D., Va.), along with 29 of their colleagues, sent a letter last week to the chairmen and ranking members of the House and Senate Armed Services Committees, urging them to include the text of the Nuclear Energy Leadership Act (NELA) in the final fiscal year 2021 National Defense Authorization Act (NDAA).

Murkowski joined Sen. Cory Booker (D., N.J.) and 18 other lawmakers in a similar letter to the Senate Armed Service Committee earlier this year. Murkowski and Booker introduced NELA on September 6, 2018 (NN, Oct. 2018, p. 39).

The House and Senate passed their respective versions of the NDAA in July, by votes of 295–125 and 86–14, respectively. (NELA provisions have been included in the Senate’s NDAA and in the House’s Clean Economy and Jobs Innovation Act.) Last month, speaking at the 2020 Defense News Conference, Rep. Mac Thornberry (R., Texas), ranking member of the House Armed Services Committee, said that the final House and Senate conference report on the NDAA should be coming out soon after the November election.

The Joseph M. Farley nuclear plant, in Columbia, Ala.

The Nuclear Regulatory Commission has approved Southern Nuclear Operating Company’s request to increase the capacity of the two Farley reactors by approximately 1.7 percent. The company applied for the requisite operating license amendments on October 30 of last year. The NRC issued the amendments on October 9.

Located in Columbia, Ala., the Farley plant houses two three-loop Westinghouse pressurized water reactors. Unit 1 was connected to the grid in 1977, and Unit 2 came on line in 1981.

According to an NRC press release on October 21, NRC staff determined that Southern Nuclear could safely increase both reactors’ heat output, primarily through more accurate means of measuring feedwater flow. Southern Nuclear is also improving some plant systems not regulated by the NRC to more efficiently convert the increased reactor output to electricity.

Chirica

The Nuclear Energy Institute and the Romanian Atomic Forum (Romatom) have signed a memorandum of understanding for cooperation in civil applications of nuclear energy, according to Romatom on October 14.

The MOU was signed less than a week after the United States and Romania initialed a draft intergovernmental agreement for cooperation on the construction of two additional reactors at Romania’s Cernavoda nuclear power plant and the refurbishment of Unit 1. Cernavoda currently houses two operating reactors—Units 1 and 2, twin 650-MWe CANDU-6 pressurized heavy-water reactors.

Maria Korsnick, NEI’s president and chief executive officer, and Teodor Chirica, Romatom’s honorary president, signed the MOU during a webinar on investment opportunities and the capabilities of the U.S. and Romanian nuclear industries. Also in attendance were Tommy Joyce, the U.S. Department of Energy’s deputy assistant secretary for global energy security and multilateral engagement, and Dan Dragan, secretary of state in the Romanian Ministry of Energy, Economy, and Business Environment.

Georgia Power has announced the completion of cold hydro testing at Vogtle-3, one of two 1,100-MWe Westinghouse AP1000 pressurized water reactors under construction at the Vogtle site near Waynesboro, Ga.

Unit 3 construction is now approximately 94 percent complete, and the total Vogtle-3 and -4 expansion project is about 88 percent complete, according to the company’s October 19 announcement. The last major test for Vogtle-3 before initial fuel loading is hot functional testing.

Brouillette

Naimski

Potential U.S. involvement in the development of a civil nuclear power program for Poland took another step forward on October 19 when U.S. Secretary of Energy Dan Brouillette and Poland’s secretary of state for strategic energy infrastructure, Piotr Naimski, discussed the signing of the first intergovernmental agreement toward that end.

The 30-year agreement, which Brouillette has signed and which will be signed by Naimski once the document is received in Warsaw, becomes effective upon the exchange of diplomatic notes between the two nations informing each other that they have completed all applicable requirements for its entry into force, according to a Department of Energy press release.

Utah Associated Municipal Power Systems (UAMPS) announced on October 16 that the Department of Energy has approved a $1.4-billion, multiyear cost-share award to Carbon Free Power Project LLC, a new business entity wholly owned by UAMPS that was created for the development and construction of a 720-MWe NuScale power plant—the Carbon Free Power Project (CFPP)—to be sited at Idaho National Laboratory. The funding comes as UAMPS prepares to develop the first combined license application (COLA) for a small modular reactor.

The Nuclear Regulatory Commission last week announced the publication of the 2020–2021 Information Digest, which describes the agency's mission, responsibilities, accomplishments, and activities and provides general information on nuclear-related topics. The digest is published annually and, beginning this year, will be available electronically only on the NRC’s website.

The complete 227-page document or individual sections, including a handy nine-page “NRC at a Glance” section, is available for download. An audiobook of the digest is also available at the site.

Speaking last week at a virtual event of the Empire Club of Canada, Bruce Power president and chief executive officer Mike Rencheck announced “NZ-2050”—the company’s strategy for helping Canada achieve its stated goal of net-zero emissions by 2050.

Canada’s only private sector nuclear generator, Bruce Power operates the Bruce Nuclear Generation Station, located in Kincardine, Ontario. The plant houses eight units, all CANDU pressurized heavy-water reactors, with a total output of 6,288 MWe.

At first glance, the Advanced Test Reactor Critical (ATRC) Facility has very little in common with a full-size 800- or 1,000-MW nuclear power reactor. The similarities are there, however, as are the lessons to be learned from efforts to modernize the instrumentation and control systems that make them valuable assets, far beyond what their designers had envisioned.

One of four research and test reactors at Idaho National Laboratory, the ATRC is a low-power critical facility that directly supports the operations of INL’s 250-MW Advanced Test Reactor (ATR). Located in the same building, the ATR and the ATRC share the canal used for storing fuel and experiment assemblies between operating cycles.

The Nuclear Regulatory Commission has accepted for review an application from Dominion Energy to renew for 20 years the previously renewed operating licenses for North Anna-1 and -2, according to a notice published in yesterday’s Federal Register. Dominion submitted the application on August 24.

A version of the 1,899-page subsequent license renewal application without proprietary details is available to the public on the NRC’s website.
