The National Commission on Grid Resilience (NCGR) has released a report recommending a series of actions to better address threats to the bulk power system in the United States. While noting that “substantial progress has been made in a short time” toward improving grid resilience, the report declares that “more needs to be done, and in record time.”

The Department of Energy announced on August 14 that $5.1 million would go to the Electric Power Research Institute (EPRI) to develop modular-in-chamber electron beam welding capabilities to support reactor pressure vessel welding for NuScale Power’s small modular reactor design. The project has a total value of nearly $6.5 million, of which the DOE will provide about $5.1 million.

The Department of Energy established the Consortium for Advanced Simulation of Light Water Reactors (CASL) at Oak Ridge National Laboratory in 2010 as a national collaboration of government, academia, and industry to help the nuclear industry extend the life of the current reactor fleet and develop more efficient next-generation reactors. On August 13, ORNL issued a news release and video to celebrate the achievements of CASL, which concluded its mission in June.

Stars contain their plasma with the force of gravity, but here on earth, plasma in fusion tokamaks must be magnetically confined. That confinement is tenuous, because tokamaks are subject to edge localized modes (ELM)—intense bursts of heat and particles that must be controlled to prevent instabilities and damage to the fusion reactor.

Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and at General Atomics (GA) recently published a paper in Physical Review Letters explaining this tokamak restriction and a potential path to overcome it. They have developed a new model for ELM suppression in the DIII-D National Fusion Facility, which is operated by GA for the DOE. PPPL physicists Qiming Hu and Raffi Nazikian are the lead authors of the paper, which was announced on August 10 by PPPL.

Over the past several years there has been renewed interest in the development and licensing of advanced reactors that will be very different from the light-water reactors that are currently used to generate electricity in the United States. For example, some advanced reactors will use gas, liquid metal, or molten salt as a coolant, some will have a fast neutron spectrum, and some will be much smaller in size than current generation LWRs. The many possible applications for these reactors include electricity production, process heat, research and testing, isotope generation, and space applications.

To prepare for potential non-LWR application submittals, the U.S. Nuclear Regulatory Commission has studied the issues and written many new relevant documents. In addition, there is a long history of the NRC regulating non-LWRs that might be useful to study to help in addressing new submittals. To some extent, this has been chronicled in general histories of the NRC. Our objective herein is to describe the NRC’s history specifically with the licensing of non-LWRs and to explain some of the most salient regulatory and licensing issues.

This year’s Utility Working Conference Virtual Summit, held on August 11, had a dynamic opening plenary and a packed roster of informative sessions. Following is a recap of a 4:00 p.m. (EDT) session that took place.

Shaping a regulatory framework to support future innovation

Session organizers Amir Afzali and Brandon Chisholm of Southern Company crafted a session titled “Advanced Reactors: Innovation in Nuclear Technology Needs Agile, Efficient, and Predictable Regulatory Framework” in the Regulatory Relations track of the UWC Virtual Summit. The panel discussion was focused on how to enable innovation in a regulated industry to support advanced reactor deployments within 10 years. “The right regulatory framework can enable innovation, and right-sizing the regulatory requirements incentivizes innovation,” Chisholm said during his opening comments.

The French nuclear safety authority, Autorité de Sûreté Nucléaire (ASN), has released an International Atomic Energy Agency report on a pre-operational safety review team (pre-OSART) mission conducted in 2019 at the Flamanville nuclear plant to review the safety status of its Unit 3 EPR reactor, currently under construction.

According to the report, the pre-OSART mission at Flamanville-3 reviewed the following areas: leadership and management for safety, training and qualification, operations, maintenance, technical support, operating experience feedback, radiation protection, chemistry, emergency preparedness and response, accident management, human-technology-organization interaction, and commissioning. The review was performed by a team from Canada, Finland, Germany, Russia, Spain, Sweden, and the United States, along with IAEA staff members and observers from Russia and South Korea.

Overall findings of a survey of Nuclear Regulatory Commission personnel indicate that while the NRC maintains a few strengths compared to external benchmarks, results have declined since 2015 in a number of areas, according to a recent report from the NRC’s Office of the Inspector General (OIG).

The survey was conducted in February 2020 by Willis Towers Watson, a global risk-management, insurance brokerage, and advisory firm that has partnered with the OIG for more than 20 years to assess the NRC’s safety culture and climate, as well as other aspects of employee experience.

Bowing to current COVID-19 realities but buoyed by the success of June’s virtual Annual Meeting, ANS event planners returned to the virtual realm for this year’s Utility Working Conference. Originally scheduled for August 9–12 at Marco Island, Fla., the condensed event was held Wednesday, August 11, wherever registrants’ computer devices happened to be located.

In addition to 26 educational sessions and workshops, UWC 2020 featured an opening plenary session titled “Achieving Transformational Change: A leadership discussion,” moderated by Bob Coward, MPR Associates principal officer and ANS past president (2017–2018). Plenary panelists included representatives from three utilities—Arizona Public Service (APS), Exelon, and Xcel Energy—plus the Institute of Nuclear Power Operations (INPO) and the Nuclear Regulatory Commission.

The draft American Nuclear Infrastructure Act of 2020 (ANIA) received support from three energy experts at a Senate Committee on Environment and Public Works hearing on August 5. The legislation had been introduced the previous week by Sen. John Barrasso (R., Wyo.), the committee’s chairman.

Testifying before the committee were Amy Roma, a founding member of the Nuclear Energy and National Security Coalition at the Atlantic Council and an attorney at Hogan Lovells; W. Paul Goranson, chief operating officer of Energy Fuels Inc. and president of the Uranium Producers of America (UPA); and Armond Cohen, executive director of the Clean Air Task Force (CATF). (For more on the CATF, remember to check out next month’s Nuclear News.)

Fuel loading has commenced at Unit 1 of the Belarusian nuclear power plant, according to Rosatom, Russia’s state-owned nuclear energy corporation. The first fuel assembly was loaded into the unit at 11:45 a.m. (local time) on August 7, the company said, adding that a total of 163 assemblies will have been loaded by month’s end.

The plant, Belarus’s only nuclear power facility, houses two 1,109-MWe VVER-1200 pressurized water reactors. Unit 1 is scheduled to begin commercial operation later this year, with a Unit 2 startup slated for 2021.

McNamee

Bernard McNamee, one of the four current members of the Federal Energy Regulatory Commission, has announced that he will be leaving the agency next month, narrowing its majority to two Republicans to one Democrat. As Newswire reported on July 30, the White House intends to nominate Republican Mark C. Christie to fill McNamee’s seat and Democrat Allison Clements to fill FERC’s remaining Democratic seat.

We owe a debt of gratitude to Dennis Wilkinson, born 102 years ago today. Dennis did so much for the nuclear power industry—both in the Navy and in the commercial sector. When people first met him, he invariably stuck out his hand, grinned, and said, “Hi, I’m Dennis.” No pretense, no pomposity, no self-importance. Supremely confident and brilliant, he was also compassionate and warm with an engaging sense of humor. Many people he met became life-long friends, as he often said that “friendship is forever.”

Penfield

Enos

Energy Harbor’s Beaver Valley plant, located about 34 miles northwest of Pittsburgh, Pa., was one of many nuclear sites preparing for a scheduled outage as the coronavirus pandemic intensified in March. The baseline objective of any planned outage—to complete refueling on time and get back to producing power—was complicated by the need to prevent the transmission of COVID-19.

While over 200 of the plant’s 850 staff members worked from home to support the outage, about 800 contractors were brought in for jobs that could only be done on-site. Nuclear News Staff Writer Susan Gallier talked with Beaver Valley Site Vice President Rod Penfield and General Plant Manager Matt Enos about the planning and communication required.

Beaver Valley can look forward to several more outages in the future, now that plans to shut down the two Westinghouse pressurized water reactors, each rated at about 960 MWe, were reversed in March. “The deactivation announcement happened in the middle of all our planning,” Enos said. “It’s a shame we haven’t had a chance to get together as a large group and celebrate that yet.”

While the focus remains on safe pandemic operations, the site now has two causes for celebration: an outage success and a long future ahead.

On August 4, the Department of Energy announced it will provide $57.5 million over five years to establish two multidisciplinary teams to take advantage of DOE supercomputing facilities at Argonne National Laboratory, Lawrence Berkeley National Laboratory, and Oak Ridge National Laboratory. The goal is to spur advances in the use of artificial intelligence and machine learning. Funds of $11.5 million have been made available for Fiscal Year 2020, with future funding contingent on congressional appropriations.

The Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) is at work developing and demonstrating novel energy technologies and connecting those technologies with private-sector investors. The researchers and innovators behind ARPA-E want to tell you all about it in a series of “Energy Briefs” available through the agency’s YouTube channel.

The Enforcement Committee of the Autorité des Marchés Financiers (AMF) has imposed a fine of €5 million (about $5.9 million) on Électricitéde France for providing false information about the Hinkley Point C new-build nuclear project in the United Kingdom. The committee has also imposed a €50,000 (about $59,000) fine on EDF’s former chairman and chief executive officer, Henri Proglio. According to a July 30 statement from the AMF, the false information was spread via an October 8, 2014, news release.

The AMF is described on its website as an independent public authority that regulates the French financial marketplace and its participants.
