Unit 2 at the Prairie Island nuclear power plant near Red Wing, Minn., underwent an outage in fall 2023, which included extensive work on the reactor vessel using a novel approach to replace baffle-former bolts and lower radial clevis insert bolts. The work relied on extensive analysis beforehand to determine which bolts to replace such that only the new bolts were structurally credited for performance of their safety function. This proactive approach eliminated the need for costly contingencies associated with inspections.

Despite progress made over the past years, the United Kingdom’s Nuclear Decommissioning Authority (NDA) has not seen an adequate return on investment in cleaning up the Sellafield nuclear site on England’s Cumbria coast, according to a new report by the U.K.’s National Audit Office, which scrutinizes government spending.

Nuclear reactor design and analysis never stops, and engineers have an extensive computational toolbox from which to draw for their work. Since 1979, one such tool has been the RELAP5 modeling and simulation software. Now, American Nuclear Society journal Nuclear Technology has announced plans for a special issue dedicated to RELAP5 developments and applications.

Submission of abstracts is open now; email guest editor George Mesina by November 15 to express interest.

The 2024 edition of Climate Change and Nuclear Power has been released by the International Atomic Energy Agency. The 99-page report focuses on the need for a significant increase in investment to achieve goals for expanding nuclear power.

The report: According to the IAEA, the report delves into the financing of nuclear projects as ambitious climate targets draw nearer. It also explores the imperative for financial frameworks to help nuclear energy become a cornerstone of global decarbonization efforts and highlights the challenges and best practices in financing nuclear projects.

Julie and Jim Byrne on their wedding day, May 22, 1976.

As I was finishing my studies at the University of Pittsburgh and about to graduate with a degree in civil engineering, I talked to a local navy recruiter about a position with the Seabees. He told me there were no Seabee billets, but that the navy had a nuclear power program that might interest me. When I said yes, it wasn’t long before I was whisked off to Washington, D.C., to interview with someone named Admiral Hyman Rickover. The one thing they told me was to stand up to “the kindly old gentleman.”

The day started with technical interviews and then I was ushered into the admiral’s office. I was a typical college student, and I spent my money on food and beer and not on haircuts. On seeing me, Admiral Rickover told me that I looked like a girl. After a bit of back-and-forth, he asked me a couple of other questions. His last comment to me was that I must know something and to get out of his office.

The Nuclear Regulatory Commission will host a “comment-gathering meeting” for stakeholders involved with the agency’s University Nuclear Leadership Program (UNLP) so that NRC staff can understand their views and concerns.

Gago

The governing board of the World Association of Nuclear Operators has appointed José Gago as the new WANO chair. He was formerly the general manager and chief executive officer of the Asociacion Nuclear Asco-Vandellos (ANAV) in Spain.

Gago will succeed the current chair, Tom Mitchell, on March 1, 2025, after Mitchell completes his full six-year term in the role.

Background: Gago has been ANAV’s governor at the WANO Paris Centre’s governing board since 2012 and was elected its chairperson in 2020. He has been the president of the Spanish Nuclear Society and a member of the Foro Nuclear board of directors, and he has kept close contact with the nuclear industry, serving on several advisory boards and participating in the International Atomic Energy Agency expert missions.

An article on the Huffington Post examines the prospects for re-establishing nuclear energy in Puerto Rico, uncovering a mix of positive and negative attitudes toward nuclear power in the U.S. territory.

A comprehensive set of rules and guidelines for floating nuclear power plants, Requirements for Nuclear Power Systems for Marine and Offshore Applications, has been released by the American Bureau of Shipping (ABS). According to the document, which, according to ABS, is the first of its kind for floating power plants, the rules and guidelines have been “developed for classification requirements specific to design, construction, and survey of vessels fitted with nuclear power systems whose generated power is transferred or distributed to onboard industrial or adjacent facilities.”

Fulton Station was to be a two-unit high-temperature gas-cooled reactor that was originally planned to start commercial operation in 1981 for Unit 1 and in 1983 for Unit 2. Each reactor was to provide 1,160 MWe of power. The nuclear steam supply system (NSSS) and fuel were to be developed by General Atomics (GA), and engineering firm Stone & Webster was charged with handling the construction. The Philadelphia Electric Company (PECO) had big plans for Fulton Station, but ultimately, the plant was never built.

The latest volume in the Spark Squad comic books series was released Monday as part of national Nuclear Science Week, an international event highlighting the importance of nuclear.

The weeklong observance, held annually the third week of October each year, celebrates its 15th anniversary this year.

While further editions of Spark Squad are in development, the three existing volumes and learning activities that accompany each book can be found on the DOE’s website.

Legislative proposals focused on streamlining the U.S. nuclear energy export process have circulated on Capitol Hill for several years, notably aimed at establishing a single point of contact in the government to simplify global nuclear projects.

The most recently introduced International Nuclear Energy Act (INEA) proposal (S. 826) promotes engagement with partner nations to develop a civil nuclear export strategy and to offset China’s and Russia’s growing influence on international nuclear energy development.

The Minority Serving Institution Partnership Program (MSIPP) of the Department of Energy’s National Nuclear Security Administration has recently awarded seven federal grants to projects involving minority serving institutions (MSIs).

A breakthrough in the understanding of the properties of nuclear structure has been achieved by an international team of scientists comprising researchers from Massachusetts Institute of Technology, Fermi National Accelerator Laboratory, University of Munster in Germany, and Institute of Nuclear Physics at the Polish Academy of Sciences. The team, from the nCTEQ collaboration investigating nuclear parton (quark and gluon) distribution functions, developed a quark-gluon model that combined low-energy and high-energy concepts to reproduce the properties of atomic nuclei.

A hybrid public meeting hosted by the Nuclear Regulatory Commission on October 30 will feature chair Christopher Hanson and commissioners David Wright, Annie Caputo, and Bradley Crowell.

Nuclear advocates across the country have been asking fans to cheer for more than just touchdowns this college football season. They want people to learn about and support nuclear energy.

They want them to “heart” nuclear as much as they do.

Interest in new reactor deployments and existing reactor life extensions is surging, encouraged by production and investment tax credits from the Inflation Reduction Act and led by electricity demand from tech companies. Last week alone saw Google and Amazon investing in Kairos Power’s fluoride salt–cooled reactor and X-energy’s high-temperature, gas-cooled reactor, respectively. On October 16, the DOE’s Office of Clean Energy Demonstrations issued a solicitation to award $900 million to support the initial domestic deployment of light water–cooled small modular reactor technologies.

BWX Technologies announced that the Department of Energy has approved Hanford Tank Waste Operations & Closure (H2C) to begin work under a contract valued at up to $45 billion to clean up tank waste at the Hanford Site near Richland, Wash. H2C is a limited liability company made up of BWXT Technical Services Group, Amentum Environment and Energy, and Fluor Federal Services.

It’s all about finding the sweet spot: performing the correct maintenance at the correct interval (that is, the longest possible) with the correct resources (people, parts, and plant conditions) in a safe and efficient manner.

When engineering and maintenance teams adjust periodic maintenance (PM) intervals for plant components, they must take into consideration operating history, industry experience and guidelines, and vendor recommendations. This data, in conjunction with risk assessment, can be used to stretch maintenance intervals. If a valve fails before the scheduled PM, for example, the PM interval may be too long. But if a valve is overhauled during every refueling outage and the soft parts still look new each time, extending the PM interval would save money via man-hours, parts, and scope. A smaller outage work scope results in shorter outages, which results in less money spent on replacement power for the utility. That’s the real savings.
