Edesess

In a recent opinion piece in the Bulletin of the Atomic Scientists, mathematician and economist Michael Edesess writes that “The goal of net zero greenhouse gas emissions by 2050 [appears] unrealistic.” Edesess, a research associate of the EDHEC-Risk Institute, adds, “We must, in the final analysis, be realistic. Being real means that the renewable revolution requires nuclear power.”

Then: Edesess traces the history of interest in renewable energy sources to the 1970s when, he notes, climate change was not even part of the calculations. Back then, the thought was, “We only needed to reduce the oil we imported from the Middle East. Solar and wind could do that if only we could drive the cost down.” However, “For nuclear, driving the cost down was not the objective. The objective was to make nuclear power ever safer and safer. This drove nuclear power’s cost up.”

The Pittsburgh Post-Gazette’s Anya Litvak reported yesterday that Brookfield Business Partners, a subsidiary of Canada’s Brookfield Asset Management and an owner of Westinghouse Electric Company, is ready to sell the nuclear energy firm.

The total bill for the reactor expansion project at the Vogtle nuclear plant in Georgia is now expected to exceed $30 billion, according to the Associated Press. The original price tag for the two Westinghouse AP1000 units was $14 billion.

The United Kingdom’s energy minister, Greg Hands, recently presided over the opening of one of three new training centers in England aimed at supporting EDF Energy’s Hinkley Point C nuclear build project in Somerset. The centers, according to EDF, will provide locals with the skills necessary to join the ranks of about 4,000 additional workers expected to be needed for the next phase of the power station’s construction. Hands unveiled the Welding Centre of Excellence, located on the Bridgwater & Taunton College campus in Bridgwater.

Part one of this article, published in the May 2019 issue of Nuclear News[1] and last Friday on Nuclear Newswire, presented insights from the 1979 accident at Three Mile Island-­2 and addressed several issues raised by a previous Nuclear News piece on the accident[2]. Part two discusses safety improvements that have been made by both the industry and the Nuclear Regulatory Commission over the past 40 years.

U.S. secretary of state Antony Blinken and Armenian minister of foreign affairs Ararat Mirzoyan signed a memorandum of understanding last week concerning strategic civil nuclear cooperation (NCMOU).

According to the State Department, NCMOUs are used to develop stronger ties between the United States and partner countries’ nuclear experts, industry, and researchers, as well as to provide support for the U.S. civil nuclear industry and nuclear nonproliferation goals.

Bloomberg recently reported that nuclear power production in France declined to its lowest level in almost two years in April, with power output during that month falling to 21.7 TWh. The decline occurred as Électricité de France (EDF), one of the country’s major energy suppliers, dealt with long-term inspection-and maintenance-related halts to the operation of many of its 56 domestic nuclear reactors.

The Nuclear Regulatory Commission turned the tables a bit on its inspector general’s office this week, releasing its response to a March 25 OIG event inquiry that criticized an NRC inspection at California’s Diablo Canyon nuclear power plant, performed after a July 2020 auxiliary feedwater (AFW) system failure at Unit 2.

The response highlights a number of what the agency terms “factual errors” and takes issue with several portions of the OIG report.

Finnish energy company Fennovoima has terminated, effective immediately, its engineering, procurement, and construction (EPC) contract with RAOS Project Oy, a subsidiary of Russia’s Rosatom, for the delivery of a 1,200-MWe VVER-1200 pressurized water reactor at the Hanhikivi site in Finland’s Pyhäjoki municipality.

China’s State Council recently approved the construction of four Westinghouse AP1000 reactors—two at China’s Sanmen plant in Zhejiang Province and two at the Haiyang plant in Shandong Province.

The plants currently house two AP1000 units each. Sanmen’s reactors are rated at 1,157 MWe and Haiyang’s at 1,170 MWe. Sanmen-1 and -2 began commercial operation in 2018. Haiyang-1 started commercial operation in 2018, and Haiyang-2 in 2019.

NuScale Power has signed a collaboration agreement with the U.S. Reactor Forging Consortium (RFC) to leverage the nation’s forging supply chain to prepare for the deployment of NuScale’s small modular reactor technology and to support, maintain, and expand U.S. manufacturing jobs.

California Gov. Gavin Newsom told the Los Angeles Times editorial board last week that his administration would look into using the federal government’s Civil Nuclear Credit Program to keep Pacific Gas and Electric Company’s Diablo Canyon nuclear plant in operation beyond its scheduled 2025 closure date.

“The requirement is by May 19 to submit an application, or you miss the opportunity to draw down any federal funds if you want to extend the life of that plant,” Newsom told the board, according to an April 29 LA Times piece. “We would be remiss not to put that on the table as an option.”

The Waste Management Symposia, the premier forum on the management and disposition of radioactive waste, took place in person this year March 6–10 in Phoenix, Ariz., after being held virtually in 2021 due to the COVID-­19 pandemic. With more than 2,100 paid participants, the prevailing feeling at the conference was one of getting back to normal after two long years without face-­to-­face contact.

Upton

McMorris Rodgers

Rep. Cathy McMorris Rodgers (R., Wash.), ranking member of the House Energy and Commerce Committee, and Fred Upton (R., Mich.), ranking member of the Subcommittee on Energy, sent a letter to energy secretary Jennifer Granholm on April 27 urging that more be done to secure America’s nuclear energy sector.

Excerpt: “Russia’s invasion of Ukraine exposes the risks of weakening American energy security,” McMorris Rodgers and Upton write. “These risks extend beyond our oil and gas assets to include supply vulnerabilities in our civilian nuclear sector. This sector is essential for national and energy security and for strengthening the geostrategic relationships necessary to compete with Russia, China, and other adversaries.

Small modular reactor developer NuScale Power has signed a memorandum of understanding with three South Korean companies—Doosan Enerbility Company, GS Energy Corporation, and Samsung C&T Corporation—to explore the deployment of NuScale’s VOYGR power plants in Asia.

The accident at Unit 2 of the Three Mile Island nuclear power plant on March 28, 1979, was an extremely complex event. It was produced by numerous preexisting plant conditions, many systemic issues in the industry and the Nuclear Regulatory Commission, unanticipated operator actions, previously unrecognized thermal-­hydraulic phenomena in the reactor coolant system (RCS), and the unprecedented challenge of managing a severely degraded core.

The director general of the International Atomic Energy Agency, Rafael Mariano Grossi, led a mission to Ukraine’s Chernobyl nuclear plant this week to address ongoing radiological safety concerns at the shuttered site following five weeks (February 24–March 31) of Russian military occupation.

Bechtel has signed memorandums of understanding with a dozen Polish companies for the potential development of two nuclear power plants as Poland seeks to lessen its dependence on domestic coal and Russian imports for its energy supply.

The MOUs were signed on April 25 during a ceremony at the U.S. ambassador’s residence in Warsaw. Offering services ranging from earthwork and infrastructure construction to concrete, tunneling, electrical installations, and heavy cranes, the 12 Polish firms are BAKS, Budimex, Doraco, Energoprojekt-Katowice, Hitachi Energy Poland, ILF, KB Pomorze, Mostostal Warzsawa, Polimex Mostostal, Protea Group, Vistal Gdynia, and Zarmen.

The Nuclear Regulatory Commission is seeking input from the public regarding the first set of results from its multiyear Level 3 Probabilistic Risk Assessment Project to analyze risk at a reference two-reactor nuclear power plant site.

The project, which began in 2012, updates risk insights obtained from work done more than 30 years ago, according to the NRC. The project examines a reference site with two large pressurized water reactors and associated spent fuel. It builds on Level 1 (possible reactor core damage scenarios) and Level 2 (possible radioactive material release scenarios) analyses to estimate potential health effects and economic impacts.

“If the electorate through their elected leaders demand stable or lower electricity costs, and new coal is off the table, only nuclear power offers hope,” writes nuclear engineer Joseph Somsel in reference to the Philippines presidential election, scheduled for May 9. Somsel, who expressed his views on the Nuclear Engineering International website this month, notes that the leading ticket in the election consists of presidential candidate Ferdinand Marcos Jr., son of the former dictator, and vice presidential candidate Sara Duterte, daughter of the current president. The ticket has been running ads supporting nuclear power while condemning high electricity prices.
