International nuclear safeguards verification relies on a precise count of isotope particles collected on swipes during International Atomic Energy Agency inspections of nuclear facilities and isolated through a series of lengthy chemical separations that can take about 30 days to complete. On October 15, Oak Ridge National Laboratory—a member of the IAEA’s Network of Analytical Laboratories (NWAL)—announced that analytical chemists at the site have developed a faster way to measure isotopic ratios of uranium and plutonium collected on swipes, which could help IAEA analysts detect the presence of undeclared nuclear activities or material.

This month’s Nuclear News is dedicated to the people and technology that keep our nuclear energy facilities running. It’s one of the great untold stories of the modern industrial world: how a band of highly trained people have repeatedly and skillfully applied novel technology to keep decades-old nuclear plants running at peak performance. The feat itself can be hard for the uninitiated to fathom. It’s as if a 30-year-old pickup truck was still on the retail auto market and beating out brand-new models in Consumer Reports’ vehicle safety and reliability ratings.

Nuclear sustainability was the marquee topic at the 2021 ANS Utility Working Conference, held at Marco Island, Fla., in August. It was the first in-person meeting ANS has held since COVID emerged in early 2020. It was also my first UWC, so admittedly I have only a secondhand understanding of the “before” times.

The International Energy Agency released its flagship report, World Energy Outlook 2021, on October 13, “at a time when policymakers are contending with the impacts of both climate change and volatile energy markets” and ahead of the COP26 Climate Change Conference in Glasgow, which begins October 31. With a net-zero emissions by 2050 (NZE) scenario that calls for nuclear power capacity to almost double by 2050, the report acknowledges that rapid development of advanced nuclear technologies could expand opportunities for nuclear energy to provide low-carbon electricity, heat, and hydrogen.

The nuclear industry has historically relied on intermittent ultrasonic test and visual inspections of pressurized water reactor components to identify and manage degradation. While this reactive approach has proven to be effective, imagine a scenario in which the degradation could propagate throughout the reactor internals, making a more proactive measure necessary to avoid a major enterprise risk to the plant. Could a utility identify the onset of degradation within the reactor internals during plant operation? If so, could a repair be developed prior to the next refueling outage to prevent additional, cascading degradation? That is exactly the situation that Public Service Enterprise Group (PSEG) and Westinghouse engineers were able to navigate over the course of the 2019–2020 operating cycle at Salem Unit 1, resulting in a tremendous success for the plant and a historic landmark in the nuclear industry, while earning the team a 2021 Nuclear Energy Institute Top Innovative Practice (TIP) award.

French utility giant Électricité de France has thrown its chapeau into the ring to be the large-reactor supplier for Poland’s embryonic nuclear power program, joining U.S.-based Westinghouse Electric Company, which has made concerted efforts this year to convince Poland to choose its AP1000 technology.

On Tuesday, EDF submitted a nonbinding preliminary offer to the Polish government for the construction of four to six EPR reactors, representing a total installed capacity of 6.6 to 9.9 GWe across two to three sites.

The pitch: The offer “covers all key parameters of the program, such as plant configuration, industrial scheme, plans for the development of the local supply chain, cost estimate, and schedule,” EDF said in a press release, adding that its proposal “aims at setting the principles for a Polish-French strategic partnership framework in support of Poland’s ambitious energy transition plan, aligned with the European carbon neutrality target.”

The Nuclear Innovation Alliance (NIA) has followed up its report, Advanced Nuclear Technology: A Primer, published last month, with the release of two new reports on the subject—one for policymakers, the other for investors.

For policymakers: According to the NIA, Advanced Nuclear Reactors for State Policymakers, in Brief provides an overview of enabling federal policies and looks at state options to incentivize local development of advanced reactors. In addition, the report features a series of “topical briefs” on the characteristics of advanced reactors with respect to safety, economic benefits, waste remediation, flexibility and dispatchability, and timing and development. The report also contains case studies of state-specific advanced nuclear projects such as the Natrium reactor demonstration project in Wyoming, Energy Northwest’s plans in Washington state, Utah Associated Municipal Power Systems’ consortium for the first light water small modular reactor, and the Nuclear Alternative Project in Puerto Rico.

Opining online, journalist urges regulatory flexibility for new reactors

October 13, 2021, 2:43PMANS Nuclear Cafe

In his article, “The nuclear policy America needs,” journalist Matthew Yglesias says upfront that he is not a “nuclear bro.” He is not a scientist or a nuclear engineer. But he is part of an open, online conversation about the energy policy decisions shaping our future. And in the article posted on newsletter platform Substack on October 12, Yglesias says that nuclear prospects should not be determined by a zero-sum competition between zero-carbon energy resources. Instead, he says, “What nuclear really needs is specific regulatory changes that would give advanced reactor designs a chance to prove themselves.”

Kevin Marsh, former chief executive officer and chairman of the board of directors of SCANA Corporation, has become the first person to be sentenced to prison for involvement in the 2017 collapse of the $10 billion Summer nuclear plant expansion project. Marsh was sentenced in federal court on October 7 and in state court on October 11.

The failure to complete the construction of two Westinghouse AP1000 reactors at the single-unit nuclear plant in Jenkinsville, S.C., cost ratepayers and investors billions, damaged the brands of then owners SCANA and Santee Cooper, and put some 6,000 people out of work.

Over the course of the last year, many power plants have shortened, postponed, or rescheduled their maintenance outages due to the pandemic. Unfortunately, this has caused some critical maintenance activities to be put on the back burner. For some in the power generation industry, this has presented uncertainties as the volume of unplanned outages caused by deferred maintenance has risen.
