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.

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.

For U.S. nuclear plants now undergoing decommissioning and those about to begin the process, environmental remediation has remained relatively consistent on the nuclear side with respect to contaminated soil and groundwater cleanup. However, non-­radiological chemical remediation has been shifting as new and emerging compounds are getting attention from the public and from the Environmental Protection Agency and state agencies.

“A group of professionals having fun in the fields of decommissioning and environmental sciences for the nuclear industry.”

That’s how the ANS DESD describes itself on its website. The focus of this professional division is the development and use of skills and technologies needed for the optimal management of the end-­of-­life care (decommissioning, decontamination, and remediation), long-­term surveillance, and maintenance of nuclear installations, materials, facilities, and sites.

Depending on where you reside on this nuclear technology world of ours, you may care a great deal, or not at all, about who happens to be sitting on the Nuclear Regulatory Commission at any given point in time. If you live on the Department of Energy continent or the Academia continent, it’s probably not a big deal. If you are on the Nuclear Power Plant Operator continent or the Vendor continent (which are actually part of the same landmass), it is quite important. If you are on the NRC island, it’s huge.

The NRC comprises five presidentially appointed, U.S. Senate–confirmed commissioners who are commonly referred to as “the Commission,” and approximately 3,000 federal employees referred to as the staff. The Commission oversees the NRC staff; together, they license and regulate the nation’s civilian use of radioactive materials to provide reasonable assurance of adequate protection of public health and safety. The president of the United States designates one of the commissioners to serve as chairman, the principal executive officer of and the official spokesperson for the agency.

The Nuclear Regulatory Commission is relinquishing its licensing authority for exports of deuterium for nonnuclear use to the Department of Commerce’s Bureau of Industry and Security. The NRC said that the change reflects the growing peaceful use of deuterium, including heavy water, as well as deuterium gas and deuterium or deuterated compounds, for nonnuclear industrial and research activities.

The National Institute of Standards and Technology (NIST) has submitted two reports and supplemental information to the Nuclear Regulatory Commission after conducting a root cause analysis of the February 2021 fuel failure and resultant alert at the NIST Center for Neutron Research (NCNR) in Gaithersburg, Md. While the 20-MWt NCNR research reactor remains shut down, scuttling the plans of researchers who rely on it as a source of both cold and thermal neutrons, NIST states in an October 4 update that it has requested permission to restart the reactor, contingent upon meeting all 18 corrective actions identified.

Citing national security interests, the Nuclear Regulatory Commission has issued an order suspending the general license authority to export radioactive material and deuterium to China General Nuclear (CGN) and its subsidiaries or related entities.

The NRC licensees subject to the order had been authorized to ship radioactive materials and heavy water to China through a general license granted in sections 110.21 through 110.24 of 10 CFR Part 110. Notice of the order was published in the October 1 Federal Register.

For any nuclear power plant that has been permanently shut down, site restoration is the ultimate decommissioning goal when contracting with a utility to demolish a facility. The task, however, is not as simple as mobilizing heavy equipment and waving a wrecking ball or planting explosives to implode the facility, then loading up the debris and sending it to a landfill.

There is a real science and engineering approach necessary to safely restore the land to its original state. That has been the goal for EnergySolutions over the past decade as the company works to safely decommission shuttered nuclear power plants—packaging, transporting, and disposing of the waste, and restoring the sites for whatever reuse the owners and host communities see fit.

The Nuclear Regulatory Commission has issued a license to Interim Storage Partners (ISP), a joint venture of Waste Control Specialists and Orano USA, to construct and operate a consolidated interim storage facility for spent nuclear fuel in Andrews, Texas. Issued on September 13, the license comes just four days after Texas governor Greg Abbott signed a bill to block such a facility from being built in the state.

The Nuclear Regulatory Commission has extended its orders transferring the licenses for the La Crosse and Zion nuclear power plants from EnergySolutions back to the plant owners until late 2022. This is the third time the NRC has extended the effectiveness of the license transfer orders for the decommissioned plants since approving them in 2019.

Pamela Cowen

Having spent more than 25 years in the commercial nuclear power community, Pam Cowan has spent time in both the front- and back-end operations of nuclear power. It is this experience that she draws upon as the senior vice president and chief operating officer of Holtec Decommissioning International (HDI) to help her build a growing fleet of power plants undergoing decommissioning and demolition.

Cowan, who came to HDI from the Nuclear Energy Institute, is also senior vice president of decommissioning and regulatory affairs for HDI parent company Holtec International and president of the Nuclear Asset Management Company, the owner of the plants. Cowan also serves as a member of the board of directors of Comprehensive Decommissioning International, a decommissioning general contractor, jointly owned by Holtec and SNC-Lavalin.

Radwaste Solutions spoke to Cowan about Holtec’s fleet approach to decommissioning and her plans for HDI.

(Editor's note: Soon after this article was published in Radwaste Solutions, Westinghouse Electric Company announced that Pam Cowan had been appointed president of the company's Americas operating plant services unit. Cowan takes over the business on September 21, following the retirement of current president, David Howell.)

The Nuclear Regulatory Commission is seeking qualified candidates for an open position on its Advisory Committee on Reactor Safeguards. The ACRS is an advisory group that provides independent technical review of, and advice on, matters related to the safety of existing and proposed nuclear facilities and on the adequacy of proposed reactor safety standards. It also advises the NRC on health physics and radiation protection issues.

Interested individuals can find candidate criteria and details in the Federal Register notice published on September 8 and available on the NRC’s website. Resumes will be accepted until December 7.

Resumes should be sent to Makeeka Compton and Jamila Perry, ACRS, Mail Stop T2B50, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, or e-mailed to Makeeka.Compton@nrc.gov and Jamila.Perry@nrc.gov.

More information on the ACRS is available on the NRC’s website.

The Nuclear Regulatory Commission said it was monitoring events at three nuclear power reactors in Louisiana and Mississippi after Hurricane Ida made landfall on August 29. With winds of 150 miles per hour, the Category 4 storm left more than 1 million people without power in the two states. Ida has since weakened to a tropical storm.

Researchers at Sandia National Laboratories have been expanding MELCOR—the severe accident modeling computer code used by the Nuclear Regulatory Commission to evaluate the safety of light water reactors—to study the small modular reactors and non-light-water advanced reactors that are under development. An article published in Sandia Lab News on August 27 describes in detail how MELCOR is being expanded to work with different reactor geometries, fuel types, and coolant systems.

At the box office or streaming at home, it’s fear, not truth, that sells. The laws of physics are swept aside, apocalypse is inevitable, and superpowered heroes wait until the last possible second to save the universe. It can make for great entertainment, but in the real world we need to stick with science over science fiction and be wowed by engineering, not special effects.

The truth is, science and innovation are incredible in their own right. From communications and machine learning to space travel and medical advances, technology is evolving in hyperdrive to solve real problems. With climate change and global warming here on earth, we don’t have to go looking for trouble in a galaxy far, far away.

The Nuclear Regulatory Commission is holding a virtual meeting on August 18 to discuss and receive comments regarding Holtec International’s decommissioning plan for the Indian Point nuclear power plant in New York. A hybrid meeting was held on July 29 in Tarrytown, N.Y., with a phone line available for those who opted not to attend in person. However, local storms and technical issues resulted in remote participants experiencing audio problems.
