This article first appeared in the May 2020 issue of Nuclear News.

Nuclear News reached out to leaders in the nuclear community to ask them for their views on the capacity benefits that come from nuclear. We received wide-ranging responses, from how capacity factors provide examples of the excellence of nuclear professionals, to the work being done at universities to continually improve capacity factors, to the importance of adding the word “inherent” to the conversation because forms of energy are different from one another and so inherent capacity factor is a critical piece of understanding.

If you have your own thoughts about capacity factor, please let Nuclear News know. If we collect enough comments, it may result in a Part 2 of this article in the future.

Thirty-two companies and other entities, including trade unions and nuclear supply chain businesses, have formed a consortium to urge the U.K. government to greenlight Sizewell C, the proposed nuclear new–build project at the Sizewell site in Suffolk, according to a July 14 announcement by EDF Energy.

The Emirates Nuclear Energy Corporation (ENEC) has completed construction of Unit 2 at the Barakah nuclear plant, the company announced on July 14. The plant, the Arab world’s first such facility, is located in the Al Dhafra region of Abu Dhabi, the United Arab Emirates’ capital city.

Hot functional testing of the unit had been completed in August 2018, followed by structural integrity testing and integrated leak rate testing in March last year.

With construction complete, the unit has now been officially turned over to Nawah Energy Company, ENEC’s operating and maintenance subsidiary. According to the announcement, the focus at Barakah-2 now shifts to completing the operational readiness preparations, regulatory inspections, and international assessments required for obtaining an operating license from the Federal Authority for Nuclear Regulation, the UAE’s nuclear regulator.

A team from Arizona Public Service’s (APS) Palo Verde nuclear plant, in Wintersburg, Ariz., has won the Nuclear Energy Institute’s “Best of the Best” Top Innovative Practice (TIP) Award for developing in-house software applications that use machine learning to automate such time-consuming tasks as screening reports or searching maintenance logs. The award was announced July 9 during NEI’s first-ever virtual TIP Awards presentation.

Around the world in the mid-March time frame, conditions were changing rapidly due to the COVID-19 pandemic, as was everyone’s understanding of it. For nuclear power plants, the pandemic meant dealing with new government regulations and restrictions that were put in place. “U.S.-based support of international clients was especially challenging,” said Mike Little, president and principal officer of Reston, Va.–based Dominion Engineering Inc. (DEI). “With border closures going into effect, we were not only focusing on the health and safety of our workers abroad, but also making sure they would be able to return home. Providing remote subject matter expertise from the U.S. through our international service partners was critical to successful job execution during this time.”

Unit 1 of Canada’s four-unit Darlington nuclear power plant, located in Clarington, Ontario, set a North American record on July 9 with 895 consecutive days of operation, according to Ontario Power Generation (OPG), the plant’s owner and operator.

The previous record of 894 days was held by Pickering-7, also part of OPG’s nuclear fleet. The reactors at the Darlington and Pickering plants are CANDU pressurized heavy-water reactors. Darlington-1, an 878-MWe PHWR, has been on line since January 26, 2018.

Closed vessel testing has been completed at Vogtle-3 at the Georgia Power site near Waynesboro, Ga., the company announced on July 14. The completion of the milestone prepares Unit 3 for cold hydro testing, which is required ahead of initial fuel load.

Vogtle-3 and -4 are the first new nuclear power reactors built in the United States in the past three decades. The new units will be powered by AP1000 reactors.

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 nuclear community’s reaction to last month’s proposal from the International Development Finance Corporation (DFC) to eliminate its legacy prohibition on financing international nuclear energy projects was unsurprisingly positive (see here and here). On the negative side of things, however, was the reaction from Sens. Bernie Sanders (I., Vt) and Edward Markey (D., Mass.), expressed in a July 10 letter to the DFC.

Federal Judge Margaret Seymour signed off on a $192.5 million settlement on July 9 in a civil lawsuit filed in 2017 by SCANA shareholders over the company’s failed Summer nuclear construction project.

Fanning

Tom Fanning, president and chief executive officer of Southern Company, on July 10 announced via Twitter that he has tested positive for COVID-19. One of the largest U.S. utilities, Southern is the parent company of the owners and operators of the Farley, Hatch, and Vogtle nuclear power plants.

Also on July 10, the state of Georgia obliterated its record for the number of COVID-19 cases in a single day, reporting 4,484 new cases, topping the previous record by more than 1,000. Fanning lives in Atlanta.

Citing the history of cost overruns and delays with the EPR projects at Flamanville and Olkiluoto, France’s public auditor told Électricité de France via a July 9 report that it needs to ensure financing and profitability for projects involving its proposed EPR2 reactor before moving those plans forward. The EPR2 is being designed by EDF’s Framatome unit in a bid to make a less costly version of the EPR and one that is easier to build.

The World Nuclear Association (WNA) released a white paper yesterday, Building a stronger tomorrow: Nuclear power in the post-pandemic world, outlining why nuclear projects should be part of the world’s economic and employment recovery from the COVID-19 pandemic.

According to the paper, recovery plans that include investment in nuclear energy could not only boost economic growth and jobs, but also fulfill climate change commitments and build a clean and resilient energy system.

The International Atomic Energy Agency has initiated a crowdsourcing competition for innovative ideas to boost the competitiveness of nuclear power plants, the agency announced on July 3. The deadline is August 15 for the submission of abstracts, which should be based on practices already in place at plants. Chosen participants will be invited to present their ideas at the annual Nuclear Operators’ Forum, to be held during the IAEA’s 64th IAEA General Conference, scheduled for September 21–25 in Vienna.

Preparations have begun for the construction of four nuclear reactors in Russia—two VVER-1200 units at the Leningrad plant and two VVER-TOI units near the Smolensk plant, according to Rosenergoatom, a division of Russia’s state-owned atomic energy corporation Rosatom.

Rosenergoatom operates all of Russia’s nuclear power facilities. Authorization to move forward with the new-build projects was signed by Alexey Likhachev, Rosatom’s director general.

The House Appropriations Committee yesterday released a draft of the fiscal year 2021 Energy and Water Development and Related Agencies appropriations bill, calling for higher levels of funding for nuclear energy. The legislation would fund activities at the Departments of Energy and Interior, the U.S. Army Corps of Engineers, and a number of related agencies, including the Nuclear Regulatory Commission and the Defense Nuclear Facilities Safety Board.

The United Kingdom’s Office for Nuclear Regulation (ONR) on June 30 received a nuclear site license application from EDF Energy subsidiary NNB Generation Company (SZC) Limited to construct and operate two reactors at the Sizewell site in the county of Suffolk, northeast of London.

A new report from the Paris-based OECD Nuclear Energy Agency declares that nuclear power is needed for countries to meet their Paris Agreement decarbonization and energy security policy goals, but that governmental support for a rapid reduction in the cost of new nuclear capacity through the creation of certain policy frameworks is likely necessary.

U.S. Sens. Lisa Murkowski (R., Alaska), chairman of the Senate Energy and Natural Resources Committee, and Joe Manchin (D., W.Va.), the committee’s ranking member, put their rhetorical skills to the test earlier this week as the two urged colleagues to pass the American Energy Innovation Act (AEIA), a comprehensive piece of energy policy legislation introduced by the bipartisan pair in late February (NN, Apr. 2020, p. 14).

House Democrats on June 30 rolled out a vision of what U.S. climate change policy might look like in the event the Democratic party holds its current House majority, retakes the Senate, and wins the White House in November. The vision was presented in the form of a sweeping 547-page majority staff report entitled Solving the Climate Crisis: The Congressional Action Plan for a Clean Energy Economy and a Healthy, Resilient, and Just America.
