The Nuclear Regulatory Commission has denied “without prejudice” Oklo Power’s application to build and operate its Aurora microreactor in Idaho, the agency announced yesterday. The denial, according to the NRC, is due to the California-based firm’s failure to provide sufficient information on several crucial topics regarding the Aurora design.

Quite a year was 2021. In the following stories, we have compiled what we feel are the past year’s top news stories—please enjoy this recap from a busy year in the nuclear community. But first, what about ANS itself? Let’s look at some of ANS’s activities in 2021.

Rempe

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards has elected Joy Rempe as chair, Walter Kirchner as vice chair, and David Petti as member-at-large. All three are ANS members.

“I am honored that my colleagues on the ACRS elected me to this position,” said Rempe, of Rempe and Associates. “The leadership team looks forward to ensuring that the ACRS continues its tradition of providing the commission advice on safety issues.”

Bios: Rempe has more than 35 years of experience in the areas of reactor safety and instrumentation performance. Prior to retiring as a Laboratory Fellow at Idaho National Laboratory, she founded an instrumentation development and deployment laboratory, which supported irradiation testing in U.S. and international facilities.

Throughout the history of commercial nuclear power plant operations, there have been events that changed the industry. The incidents at Three Mile Island and Fukushima brought about great advancements in how nuclear plants are operated, including additional safety measures and supplemental training on how to prevent such events. Looking forward, the commercial nuclear industry is poised for a similar transformative change: one motivated by financial viability.

Marzano

Matthew Marzano is beginning a year of service in Washington, D.C., as the 2022 Glenn T. Seaborg Congressional Science and Engineering Fellow, and he is excited about bringing his nuclear power experience to the policy-making process.

“I am most looking forward to the opportunity to learn about the legislative process and the conduct of business on Capitol Hill. Oftentimes we are presented a picture of a dysfunctional Congress through the media, but I’ve gathered through the orientation process and congressional interviews that collaboration is alive and well, especially in the area of clean energy,” Marzano said.

The Nuclear Regulatory Commission has proposed a $150,000 fine for apparent security-related violations at the Oyster Creek nuclear power plant in New Jersey. Oyster Creek permanently ceased operations in 2018, and ownership of the plant was transferred to Holtec Decommissioning International for decommissioning in July 2019.

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The June issue reviewed some topics in human factors and instrumentation and controls such as the article below that looks at the NRC's review of digital instrumentation systems in the current fleet.

The Nuclear Regulatory Commission^a first formally developed infrastructure for the review of digital instrumentation and control (I&C) systems in the 1990s. Although the current fleet of nuclear power plants in the United States was originally designed and constructed with analog systems, the U.S. nuclear industry has for more than 30 years been working to upgrade these older systems with modern digital equipment.

A former senior resident inspector for the Nuclear Regulatory Commission pleaded guilty on December 13 in the U.S. District Court for the Western District of Virginia to making false statements on NRC inspection reports. Such false statements violate federal statutes and carry a maximum penalty of five years in prison.

The Nuclear Regulatory Commission has approved the transfer of the Palisades nuclear power plant licenses from Entergy Nuclear Operations to Holtec International, as owner, and Holtec Decommissioning International (HDI), as decommissioning operator. Holtec and HDI intend to decommission the single-unit pressurized water reactor, located in Covert, Mich., under an accelerated schedule.

In a November letter to President Biden, ANS president Steven Nesbit and U.S. Nuclear Industry Council president and chief executive officer Bud Albright urged the president to proceed with nominations for the two open seats on the Nuclear Regulatory Commission. The letter stated, “The NRC operates best with a full complement of five qualified commissioners who have diverse and complementary backgrounds. . . . Unfortunately, the commission was last at full strength in January 2021, nearly a year ago.”

The track record for the successful decommissioning of nuclear facilities, both nationally and internationally, is impressive. In the United States, we have decommissioned many nuclear facilities, including complex materials sites, uranium recovery sites, research and test reactors, and nuclear power plants. To date, according to the Nuclear Regulatory Commission, 10 nuclear power plants have been completely decommissioned for unrestricted use, and another 26 power reactor sites are currently undergoing decommissioning through either SAFSTOR or DECON, following NRC regulatory requirements. In addition, the Nuclear Energy Institute identifies three nuclear power plants that were successfully decommissioned outside of NRC jurisdiction. While such a track record is impressive, the nuclear industry must be vigilant in focusing on lessons learned in order to continue to make gains in efficiency, cost savings, improved environmental stewardship, and enhanced stakeholder confidence. In reviewing the outcomes of decommissioning over many years, a number of key lessons learned have emerged.

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.

The license for Pacific Gas & Electric Company’s Humboldt Bay Unit 3 nuclear power plant near Eureka, Calif., has been terminated by the Nuclear Regulatory Commission, and the site has been released for unrestricted use. A 65-MWe boiling water reactor plant, Humboldt Bay-3 operated commercially from 1963 to 1976.

Oklo plans to fuel its demonstration microreactor with high-assay low-enriched uranium (HALEU). To secure a source of HALEU for its nth-of-a-kind microreactor, Oklo has signed a nonbinding letter of intent with Centrus Energy to cooperate on the deployment of a HALEU production facility.

The Nuclear Regulatory Commission announced on November 15 that it has awarded nearly $5.5 million in grants to support research and development activities in nuclear science, engineering, technology, and related disciplines under the University Nuclear Leadership Program (UNLP), previously known as the Integrated University Program.

Wright

In a prerecorded video speech to last week’s Decommissioning Strategy Forum in Summerlin, Nev., Nuclear Regulatory Commission commissioner David Wright addressed public concerns about the growing number of utilities transferring their nuclear power reactor licenses to outside companies for accelerated decontamination and decommissioning after plant closure.

“While the NRC’s reactor decommissioning financial assurance program considers the potential for non-utility companies to conduct decommissioning, we have heard concerns about the use of these new license transfer models, given the significant acceleration of decommissioning schedules and withdrawals from decommissioning trust funds,” Wright said in his November 1 speech.

The Nuclear Regulatory Commission on Wednesday approved a proposed rule to amend its regulations for nuclear power plants that are transitioning from operations to decommissioning. After changes requested by the NRC commissioners are made by agency staff, the proposed rule will be published in the Federal Register, initiating a 75-day comment period.

Steven P. Nesbit

As I write this column, it’s late September, and I’m sitting in Dulles Airport waiting for my connecting flight back to Charlotte from Vienna, Austria, where I attended the 65th General Conference of the International Atomic Energy Agency. It was quite an experience, and I want to share a few observations with you. But first, let me provide some background on the IAEA, which is perhaps not as well-­known to Americans as to those in other countries.

The IAEA was established in 1957 within the United Nations family and as an outgrowth of President Dwight Eisenhower’s famous 1953 “Atoms for Peace” speech. It is the world’s central intergovernmental forum for scientific and technical cooperation in the nuclear field. The objectives of the IAEA’s dual mission—to promote and control the use of the atom—are defined in Article II of the IAEA Statute.
