Westinghouse Electric Company has filed a pre-application regulatory engagement plan (REP) with the Nuclear Regulatory Commission for its eVinci microreactor, the company announced on Tuesday.
First reported last week by S&P Global Platts but confirmed only yesterday, small modular reactor developer NuScale Power plans to go public via a merger with Spring Valley Acquisition Corporation, a special purpose acquisition company, or SPAC. (SPACs are shell corporations listed on a stock exchange with the purpose of acquiring or merging with a private company, effectively taking that company public without going through the standard initial public offering process.)
The Nuclear Regulatory Commission has extended, for the second time, the public comment period regarding preliminary language for a proposed rule setting out a risk-informed, technology-inclusive framework for the licensing and regulation of advanced reactors, according to a notice in the December 10 Federal Register.
Luria
Gonzalez
Reps. Anthony Gonzalez (R., Ohio) and Elaine Luria (D., N.Y.) have again teamed up to launch bipartisan pronuclear legislation in the House. On December 7, with Luria as cosponsor, Gonzalez unveiled the Accelerating Nuclear Innovation through Fee Reform Act (H.R. 6154), aimed at accelerating innovation and catalyzing private sector investment in advanced nuclear reactor technologies by eliminating Nuclear Regulatory Commission review fees for advanced reactor license applications, which could reach tens of millions of dollars, disincentivizing developers from bringing new technologies to market.
Energy secretary Jennifer Granholm toured the Braidwood nuclear plant in Illinois last week as part of a statewide tour to promote the climate provisions in the recently passed trillion-dollar infrastructure law and the Build Back Better Act, over which the Senate continues to haggle.
Électricité de France recently announced the formation of an advisory board for NUWARD, France’s small modular reactor project. According to the company, the establishment of the International NUWARD Advisory Board (INAB) is a major step forward in support of the technology’s development.
The Thursday morning executive session at last week’s 2021 ANS Winter Meeting and Technology Expo brought together a group of influential nuclear-policy experts from the United States and abroad to discuss the roles nuclear can play in smoothing the pathway to net-zero emissions by 2050. Specific topics explored included the Clean Energy Ministerial (CEM) and its Nuclear Innovation Clean Energy (NICE) Future initiative, as well as last month’s COP26 climate conference in Glasgow. The session was moderated by Leah Parks, a Nuclear Regulatory Commission risk analyst and 2020 ANS Presidential Citation awardee.
Georgia Power has revised the projected commercial operation dates for Vogtle-3 and -4 a total of four times this year—most recently in October—but some experts are saying that at least one more delay is probable.
Hands
The U.K. government has confirmed its selection of the high-temperature gas-cooled reactor (HTGR) for Britain’s £170 million (about $236 million) Advanced Modular Reactor Demonstration Program.
Greg Hands, minister for energy, clean growth, and climate change, delivered the news on December 2 via a speech at the Nuclear Industry Association’s annual conference. “Following evaluation of responses received,” Hands said, “I’m pleased to announce today that we will focus on HTGRs as the technology choice for the program moving forward—with the ambition for this to lead to a demonstration by the early 2030s.”
NNL approved: “As we look to the future and the part we play as a scientific superpower, the U.K.’s unparalleled experience in gas-cooled technologies makes HTGRs the common-sense choice for pursuing advanced nuclear,” said Paul Howarth, chief executive officer at the United Kingdom’s National Nuclear Laboratory. “Following announcements already made on financing for the next stage of the Rolls-Royce SMR program and the proposed Nuclear Energy (Financing) Bill to make large-scale plants more achievable, the U.K. is primed once more to be a global leader in nuclear technologies—large, small, and advanced.”
NuScale Power announced on December 2 that its small modular reactor plants will bear the name VOYGR. According to NuScale’s announcement, “The name VOYGR demonstrates that NuScale is changing the world by creating an energy source that is smarter, cleaner, safer, and cost-competitive.”
Unit B1 at Scotland’s two-unit Hunterston B nuclear power plant was taken off line for good on November 26 after nearly 46 years of operation. A 490-MWe advanced gas-cooled reactor, the unit entered commercial operation in June 1976. Its companion AGR, Unit B2, which entered operation in March 1977, is scheduled for retirement in January.
Ontario Power Generation (OPG) has selected GE Hitachi Nuclear Energy (GEH) as its technology partner for the Darlington nuclear new-build project. The companies will work to deploy GEH’s BWRX-300 small modular reactor at OPG’s Darlington nuclear plant, located in Clarington, Ontario.
Outage time at a nuclear power plant comes with a unique set of challenges for licensed personnel. A primary responsibility for control room supervisors in any mode of operation is to maintain control of the plant configuration, which during an outage requires an all-hands-on-deck approach. Considering what is involved in taking the plant apart, upgrading plant equipment, performing once-per-cycle inspections and preventative maintenance, testing safety system functionality, and loading the next core, it’s clear why so much emphasis is placed on outage performance.
A recent study of life cycle carbon emissions at the United Kingdom’s Hinkley Point C nuclear plant finds that the facility, now under construction in Somerset, England, is likely to produce less CO2 over its lifetime than either solar or wind power.
According to the 70-page analysis—prepared by environmental consultancy Ricardo Energy & Environment for NNB Generation Company HPC Limited, the holding company for the Hinkley Point project—lifetime emissions from Hinkley Point C are likely to be about 5.5g CO2e per kWh. That amount also holds for the proposed Sizewell C plant, the study concludes. (The two 1,630-MWe EPRs at Hinkley Point C are currently scheduled to begin commercial operation in 2026 and 2027.)
In its latest financial nod of encouragement to the U.S. nuclear industry, the Department of Energy has announced awards totaling $8.5 million to five industry-led projects, with the aim of accelerating the commercial deployment of advanced reactors and fuels.
The awards are funded via the Office of Nuclear Energy’s U.S. Industry Opportunities for Advanced Nuclear Technology Development funding opportunity, which, since 2017, has invested more than $215 million in advanced nuclear technologies. Solicitations are broken down into three pathways: first-of-a-kind nuclear demonstration readiness projects, advanced reactor development projects, and direct regulatory assistance.
The Nuclear Regulatory Commission will increase its oversight of Vogtle-3—one of the two Westinghouse AP1000 reactors under construction at the Vogtle nuclear power plant in Waynesboro, Ga.—after finalizing two inspection findings involving the unit’s safety-related electrical cable raceway system. Vogtle’s operator, Southern Nuclear, was informed of the decision in a November 17 letter.
The agency had launched a special inspection at Vogtle-3 in June of this year to determine the cause and extent of construction quality issues in the raceway system, which consists primarily of conduits and cable trays designed to prevent a single event from disabling redundant safety-related equipment.
Last April, Entergy had to close its Indian Point nuclear plant. That’s despite the plant’s being recognized as one of the best-run U.S. nuclear plants. That’s also despite its 20-year license extension process having been nearly completed, with full support from the Nuclear Regulatory Commission.
This closure was due in large part to opposition by antinuclear environmental groups. These groups also mobilized existing negative public opinion on nuclear energy to get politicians to oppose the plant’s license extension. Another factor is unfair market conditions. Nuclear energy doesn’t get due government support—unlike solar, wind, and hydro—despite delivering clean, zero-emissions energy.
Statement from American Nuclear Society President Steven Nesbit and Executive Director/CEO Craig Piercy
The American Nuclear Society supports the continued operation of California's Diablo Canyon nuclear power plant. The premature shutdown of Diablo Canyon units 1 and 2, slated respectively in November 2024 and August 2025, will inflict grave harm to California's economy and environment.
The Nuclear Regulatory Commission has granted Dominion Energy’s request for an increase in the generating capacity of Millstone-3. The Richmond, Va.–based utility had applied for the power uprate last November, requesting an increase of approximately 1.6 percent.
NRC staff determined that Dominion could safely increase the reactor’s heat output, primarily through more accurate means of measuring feedwater flow, according to a November 18 press release. The NRC’s safety evaluation focused on several areas, including the nuclear steam supply systems, instrumentation and control systems, electrical systems, accident evaluations, radiological consequences, fire protection, operations and training, testing, and technical specification changes.
Westinghouse Electric Company and Energoatom, Ukraine’s state-owned nuclear utility, signed a contract in Kyiv yesterday outlining the details of an agreement to bring the Westinghouse AP1000 reactor to Ukraine’s Khmelnitsky nuclear power plant.
According to a Westinghouse press release, the contract initiates engineering and procurement of long-lead items for the reactor.
