David Gandy, the senior technical executive for nuclear materials at the Electric Power Research Institute, is charged with leading a project to lower the costs and manufacturing time for small modular reactors and advanced reactors. The Department of Energy–funded project is led by EPRI, and its collaborators include the United Kingdom–based Nuclear Advanced Manufacturing Research Center and Oregon-based reactor developer NuScale Power. The testing has focused on producing the upper and lower pressure vessel assemblies for NuScale’s 60-megawatt SMR.

Gandy said that the project team has already produced a 3,650-pound reactor upper head at 44 percent scale and has made other components as heavy as 7,000 pounds. Over the next two years, if the tests still to be conducted are successful, EPRI plans to transfer the technologies to other reactor manufacturers. Gandy expects these new technologies to be available in about five to seven years, once the testing is completed and the necessary approvals are obtained from the Nuclear Regulatory Commission and ASME.

Gandy talked about the project with Nuclear News Editor-in-Chief Rick Michal.

The United States is pursuing the objective to land humans more than 100 million miles away on Mars, and nuclear power has the potential to be a key technology in getting to the Red Planet and providing power while there. Specifically, nuclear thermal propulsion (NTP) is a promising approach that could enable astronauts to travel from Earth’s orbit to Mars and back in a fraction of the time, and with greater safety, than is available with other options.

Georgia Power, primary owner of the Vogtle nuclear plant near Waynesboro, Ga., has ordered the first nuclear fuel load for Vogtle-4, completing the initial fuel order necessary for the startup of the reactor, as well as its twin, Unit 3, the company announced on March 5.

The third Strategic Dialogue on Energy between government officials from Poland and the United States was held on February 26 as a way to extend the nations’ advanced nuclear energy cooperation. U.S. Secretary of Energy Dan Brouillette met with Piotr Naimski, Poland’s secretary of state in the chancellery of the prime minister and plenipotentiary for strategic energy infrastructure, and Poland’s Minister of Climate Michal Kurtyka at the Department of Energy headquarters in Washington, D.C. In a DOE press release, Brouillette acknowledged the U.S. nuclear industry’s continued interest in providing clean, reliable, and resilient nuclear energy to Poland as a means to strengthen their energy security. In a post on Twitter, Kurtyka described the meeting as “fruitful.”

In its report for fiscal year 2019, published in February, the Nuclear Regulatory Commission’s Office of Investigations (OI) shows a total case inventory that continues its downward trend: OI reported 160 cases in FY 2019, down 18 percent from 195 in FY 2018. The number of cases in 2015, 2016, and 2017 were 235, 231, and 209, respectively.

Exelon Generation’s Peach Bottom-2 and -3, located in Delta, Pa., have joined Florida Power & Light Company’s Turkey Point-3 and -4 as the only U.S. nuclear reactors licensed to operate for a total of 80 years.

On March 5, the Nuclear Regulatory Commission issued subsequent license renewals to Exelon for the Peach Bottom boiling water reactors, with expiration dates of August 8, 2053, for Unit 2, and July 2, 2054, for Unit 3. The FPL units received their first--in--the-nation SLRs last December (NN, Jan. 2020, p. 15).

The Nuclear Regulatory Commission is issuing a proposed interpretation of its low-­level radioactive waste disposal regulations that would permit licensees to dispose of waste by transfer to persons who hold specific disposal exemptions. The NRC said that it will consider approval of requests for specific exemptions only if they are for the disposal of very low-­level radioactive waste by land burial. Notice of the proposed interpretive rule was published in the March 6 Federal Register.

The Department of Energy’s Oak Ridge Office of Environmental Management and its contractor URS/CH2M Oak Ridge hosted a ribbon-­cutting ceremony on February 27 for the new K-­25 History Center on the site of the former uranium enrichment plant. Located next to the original foundation for the K-­25 building, the center was built to honor and preserve the stories of the workers who constructed and operated the K-­25 complex during World War II and the Cold War.

Speaking before the House Appropriations Committee’s Subcommittee on Energy and Water Development on March 3, Rita Baranwal, the Department of Energy’s assistant secretary for nuclear energy, said that the DOE has prepared a request for proposal for an interim storage site for radioactive waste. “The intent is for the basic design of an interim storage facility,” she said.

A new report from the U.S. Government Accountability Office concludes that the Nuclear Regulatory Commission’s fee-setting, billing, and budgeting processes have improved in recent years, but that industry stakeholders continue to identify challenges with these processes and that further enhancements should be implemented.

In a summary report released to its membership on March 3, the Nuclear Energy Institute lauded the nation’s commercial nuclear industry for reactor performance in 2019, citing “record highs” in electricity generation and capacity factors.

The Department of Energy announced on March 4 that it will provide $30 million for new research on fusion energy. The funding will provide $17 million for research focused specifically on artificial intelligence (AI) and machine learning (ML) approaches for the prediction of key plasma phenomena, management of facility operations, and accelerated discovery through data science, among other topics. An additional $13 million under a separate funding opportunity will be devoted to fundamental fusion theory research, including computer modeling and simulation, focused on factors affecting the behavior of hot plasmas confined by magnetic fields in fusion reactors.

The Senate on March 12 confirmed Republican James Danly to a seat on the Federal Energy Regulatory Commission by a vote of 52 to 40. All GOP senators voted to confirm, as well as three Democrats often described as “centrist”: West Virginia’s Joe Manchin, the Senate Energy and Natural Resources (ENR) Committee’s ranking member; Arizona’s Kyrsten Sinema; and Alabama’s Doug Jones.

On February 27, Sens. Lisa Murkowski (R., Alaska) and Joe Manchin (D., W.Va.) introduced the American Energy Innovation Act (AEIA), a 555-­page piece of policy legislation that incorporates over 50 energy-­related bills considered and individually reported by the Senate Energy and Natural Resources Committee last year—measures sponsored or cosponsored by more than 60 senators from both sides of the aisle.

FirstEnergy Solutions (FES) announced on February 27 that it has emerged from bankruptcy and officially taken the new name Energy Harbor Corporation. Originally the unregulated power generation arm of Akron, Ohio–based FirstEnergy Corporation, Energy Harbor remains headquartered in Akron but is no longer affiliated with FirstEnergy Corporation. The name chosen to represent the newly independent business was announced last November (NN, Jan. 2020, p. 16).

NextEra Energy announced on February 11 that its bid to buy South Carolina’s public utility, Santee Cooper, is the “recommended purchase proposal” following a formal bid invitation called for by the state’s General Assembly in May 2019 (NN, June 2019, p. 9). Competing with NextEra’s purchase offer is a reform plan put forward by Santee Cooper in an attempt to avoid a sale as the utility continues to grapple with the failed Summer-­2 and -­3 nuclear construction project and the $3.6 billion in debt incurred before the project was halted in July 2017.

A report from the South Carolina Department of Administration published on February 11 outlined the competing plans and factors that the General Assembly may want to take into consideration as it mulls the plans. A third option, a proposal by Dominion Energy to take over the management, but not the ownership, of Santee Cooper was also evaluated.

A study released by Energy Northwest on January 30 concludes that more and different electricity sources, including nuclear, will be needed to maintain energy reliability and achieve a carbon-­free energy system in the state of Washington by 2045. The study used published conservation and efficiency projections and costs and examined the value of creating additional solar and wind facilities, as well as extending the operation of the Columbia nuclear power plant beyond 2043 and deploying small modular reactors.

“Completing this study is simply the first step in a much larger decision-­making process,” said Brad Sawatzke, Energy Northwest’s chief executive officer. “Any decision to invest in new resources will take time and will only be done in the best interest of our member utilities, the people of Washington, and, of course, the environment.”

The Department of Energy was directed by the Nuclear Energy Innovation Capabilities Act of 2017 to establish the Advanced Reactor Demonstration (ARD) Program to stimulate commercial enterprises in advanced reactor deployment and facilitate U.S. private industry’s demonstration of several advanced reactors with the capability to achieve reliable, cost-­effective, and licensable designs. The ARD program was launched on February 5 with a request for information (RFI) and notice of intent (NOI) issued by the Office of Nuclear Energy’s Office of Reactor Fleet and Advanced Reactor Deployment.

The Nuclear Regulatory Commission has announced an opportunity to request an adjudicatory hearing regarding Southern Nuclear’s notice of intended operation of Unit 3 at the Vogtle nuclear power plant, located in Waynesboro, Ga. The announcement was prompted by a January 13 letter from Southern Nuclear notifying the NRC of its scheduled date of November 23, 2020, for initial fuel loading at the reactor. As required under 10 CFR 52.103(a), the notification was made more than 270 days prior to the scheduled fuel load.

A combined license was issued for Vogtle-­3 and -­4, Westinghouse-­designed AP1000 pressurized water reactors, in February 2012. The license covers both construction and operation after construction is completed if standards—known as inspections, tests, analyses, and acceptance criteria (ITAAC)—identified in the combined license are satisfied. Operation will not be permitted until the NRC staff finds that all ITAACs have been met. However, if a hearing request is granted, the NRC can allow interim operation, given reasonable assurance of adequate protection of public health and safety while the adjudicatory hearing is carried out.
