NRC proposes GEIS revision for renewing reactor licenses

January 24, 2023, 12:01PMNuclear News

The Nuclear Regulatory Commission announced on January 24 that it has directed staff to publish a proposed rule that includes an update to the license renewal generic environmental impact statement (GEIS), which is used by the agency when considering applications to renew operating reactor licenses.

The proposed rule, to appear in the Federal Register in the near future, is a response to an NRC order that concluded the license renewal GEIS did not analyze the environmental impacts of a subsequent license renewal term (from 60 to 80 years of operation).

The California Public Utilities Commission (CPUC) has voted to open a rulemaking to consider extending the lifetime of the 2,289-MW two-unit Diablo Canyon nuclear power plant. The plant, which turns 50 this year, is the only remaining operational nuclear power facility in California. It generates nearly 10 percent of the state’s electricity needs.

Forward fusion: Building a nuclear future in Wisconsin

SHINE’s isotope production building, called the Chrysalis, under construction in October 2022.

In a former farm field just outside the historic town of Janesville in south-central Wisconsin, a large concrete-and-steel building is taking shape. Dubbed the Chrysalis, the building will eventually house eight accelerator-based neutron generators, which start-up company SHINE Technologies will use to produce molybdenum-99. As the precursor to the medical radioisotope technetium-99m, Mo-99 is used in tens of millions of diagnostic procedures every year, primarily as a radioactive tracer.

At the heart of the Chrysalis will be the high-flux neutron generators, being supplied by SHINE’s sister company, Phoenix. The compact accelerators use a deuterium-tritium fusion process to produce neutrons, which in turn induce a subcritical fission reaction in an aqueous low-enriched uranium target (19.75 percent uranium-235) to produce Mo-99.

The Nuclear Regulatory Commission has accepted an application from X-energy's fuel subsidiary, TRISO-X LLC, for a proposed TRISO-X Fuel Fabrication Facility (TF3) in Oak Ridge, Tenn., X-energy announced last week. A 30-month review schedule has been developed by the NRC that would be completed by June 2025, assuming TRISO-X provides sufficient responses to expected requests for additional information (RAIs) within 30 to 60 days of their issuance. On December 16, the NRC announced that it would seek public input on the scope of its environmental review and environmental impact statement for the application and published a notice in the Federal Register.

TerraPower announces delay due to lack of fuel availability

December 19, 2022, 12:00PMNuclear News

TerraPower, the advanced nuclear company backed by Bill Gates, announced last week that the start date for its Natrium reactor has been pushed back. As Russia is currently the only commercial source of the high-assay low- enriched uranium (HALEU) the plant requires, the company faces a lack of fuel availability. TerraPower originally planned to use Russian fuel to get its demonstration reactor up and running by 2028, but Russia’s invasion of Ukraine has dashed those plans.

How excellence in plant operations will lead to a brighter nuclear future

For years the U.S. nuclear industry has done an outstanding job keeping plant availability high while simultaneously continuing to improve safety and economics. With capacity factors averaging more than 90 percent, you would think that no one would shut down an operational nuclear power plant. But that is what we have seen in a number of cases. Fortunately, this now seems to be changing. As I write this column, Diablo Canyon’s new life extension application has just been submitted to the Nuclear Regulatory Commission for review, and the Department of Energy’s program to support continued operation of nuclear power plants is providing hope that current plants will continue to have the opportunity to demonstrate their operational excellence.

How did we get here? When I ask this question—both of myself and the industry as a whole—I envision this as two sides of the same coin. Through the efforts of many we have improved our financial and economic viability, but challenges remain because the full value proposition of nuclear energy has not been realized.

NRC awards R&D grants as part of University Nuclear Leadership Program

December 7, 2022, 9:30AMNuclear News

The Nuclear Regulatory Commission’s Office of Regulatory Research recently awarded 20 new research and development grants in the University Nuclear Leadership Program (UNLP). The grants, totaling $9,998,188, are derived from the $16 million that Congress appropriated for the program for fiscal year 2022. The 20 selected proposals were among the 89 that were submitted to the NRC and peer-reviewed by the commission staff and experts from academia.

Impressions from the IAEA General Conference

There are worse places to be than Vienna, Austria, in the early fall. The place has an old-world vibe for sure. The U-Bahn doesn’t have turnstiles; it runs on the honor system. People take care to dress up before they amble down the Kärntner Strasse, the city’s main shopping district.

Every September, a little further north, 3,000 delegates from around the world, along with 200 representatives from nongovernmental organizations, descend on the Vienna International Center of the United Nations—the VIC, for short—for the International Atomic Energy Agency’s General Conference. Attendees ply its curving hallways and attend side events, engage in meetings on the margins, and tour the national booth displays.

Inside the large, purpose-built plenary hall, a seemingly endless procession of national speakers, each allotted seven minutes (with flashing red digits to let all know who’s run over time), tout their nation’s achievements in nuclear technology and express its views on nuclear matters of any sort. As an accredited NGO, ANS has a desk in the plenary complete with microphone and wireless translation headset. An IAEA plenary is a highly scripted affair—one that looks boring at first glance, but once you put the headphones on and get acclimated to the vagaries of real-time translation, a coherent and interesting picture starts to emerge.

Exporting American nuclear excellence

As I write, I am reflecting on my time at the International Atomic Energy Agency General Conference, held in Vienna during the last week of September. At the GC, I was able to meet with a number of U.S. companies that are actively doing business overseas, as well as a number of representatives from countries throughout the world that are using nuclear technology or hoping to do so. This experience—coupled with several other opportunities I have had since becoming ANS president to discuss the nuclear industry’s challenges and opportunities at national and international forums—has led me to conclude that despite the challenges our country faces, the world is still very interested in what the United States is doing in nuclear. What struck me in each of these interactions is the thirst for information about what the U.S. is doing—and what we can do for them. I think the reason for this is the enduring excellence the U.S. has always brought to the nuclear industry.

NuScale Power announced October 20 that the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) issued a letter the previous day agreeing with NRC staff’s approval of NuScale’s methodology for determining the plume exposure pathway emergency planning zone (EPZ). As approved, the methodology would permit a smaller EPZ—dependent on site-specific conditions, including seismic hazards—that provides the same level of protection to the public as the 10-mile radius EPZs used for existing U.S. nuclear power plants.

Another piece of the plan for meeting the urgent need for high-assay low-enriched uranium (HALEU) to fuel advanced reactor deployments fell into place when the Department of Energy held an Industry Day on October 14. Attendees were asked how soon they could deliver 25 metric tons per year of HALEU enriched in the United States from newly mined uranium. Offtake contracts for six or more years of HALEU production at that rate could be used to stock a DOE-owned HALEU bank to “support [HALEU] availability for civilian domestic research, development, demonstration, and commercial use.”

The Nuclear Regulatory Commission is seeking public comment on the scope of its supplemental environmental impact statement (SEIS) on the subsequent renewed licenses for Turkey Point-3 and -4, twin pressurized water reactors operated by Florida Power & Light (FPL). It’s the second time around for both the NRC and FPL—an SLR environmental scoping process conducted in 2018 already yielded renewed licenses for Turkey Point in December 2019. According to an October 7 NRC press release, “The staff intends to examine the environmental issues the commission determined were not properly evaluated for the subsequent license renewal term, as well as any new information for Turkey Point site–specific issues.”
