NRC's RIC: A clear line of sight for accident tolerant fuel deployment

March 12, 2021, 3:02PMNuclear News

To nuclear fuel suppliers, today’s operating reactors represent a defined customer base with predictable demands. Utilities must order their next fuel reload far in advance of an outage; enrichers and fabricators work to fill those orders. Adapting such a highly optimized supply chain to accommodate new products—fuels with new materials, claddings, and higher enrichments and burnups—will require alignment between all parties involved to meet the associated research, enrichment, manufacturing, regulatory, transportation, and operating experience needs.

That was the consensus during “Current Accident Tolerant Fuel Environment,” a technical session held on March 9 during the Nuclear Regulatory Commission's four-day Regulatory Information Conference (RIC, March 8-11). The session was chaired by NRC Chairman Christopher Hanson, who was taking part in his first RIC as a member of the commission.

2021 WMS: “No margin for error” in shipping radwaste

Noting that an increasing number of large components will need to be shipped from the growing number of nuclear power plants being decommissioned, Todd Eiler, director of decommissioning and decontamination engineering projects at EnergySolutions, said that the safety of nuclear waste transportation is paramount. “It is imperative as an industry that we do these shipments safely. There’s really no margin for error here,” Eiler said on March 11 during the 2021 Waste Management Symposia virtual conference panel session “Efficient and Effective Waste Management During the D&D of Nuclear Power Plants.”

While noting the stellar safety record of the nuclear industry in transporting radioactive waste, Eiler said that any incident involving a large component from a decommissioned nuclear reactor will cause national headlines, and that the industry needs to adopt a conservatism above and beyond what is already required by regulations.

As plant owners and decommissioning companies prepare to ship reactor components for disposal, Eiler said, entities that do not have direct regulatory oversight but may have some secondary involvement should not be overlooked. As an example, he said that when moving the San Onofre-1 reactor pressure vessel to Utah for disposal, EnergySolutions was not required by regulations to coordinate with the Federal Railroad Administration. “However, they are a stakeholder that definitely has authority over a project of that magnitude [where] you are transporting an irradiated component on the nation’s most in-demand rail infrastructure,” he said, adding that getting the administration’s input early in the project was important.

Baranwal

The Electric Power Research Institute today announced Rita Baranwal as its new vice president of nuclear energy and chief nuclear officer. Baranwal succeeds Neil Wilmshurst, who was promoted to senior vice president of energy system resources in November.

Baranwal most recently served as the Department of Energy’s assistant secretary for its Office of Nuclear Energy, where she managed the DOE's portfolio of nuclear research for existing and advanced reactors and new designs. Baranwal unexpectedly resigned from that position late last week.

Majumdar

Arun Majumdar, a professor of mechanical engineering at Stanford University and former vice president for energy at Google, is a leading contender for secretary of energy in a Biden administration, according to a November 12 Bloomberg story.

Chosen on November 10 to lead Biden’s Department of Energy transition team, Majumdar was also the first director of the Advanced Research Projects Agency-–Energy (ARPA-E), serving in that role from 2009 to 2012. Bloomberg quotes Jeff Navin, director of external affairs at TerraPower, as saying, “He had as good relationships with Republicans as he did with Democrats as the first director of ARPA-E, and he took the time to get to know key legislators personally.”

DOE funds EPRI welding work to support NuScale demonstration

August 17, 2020, 12:08PMNuclear News

The Department of Energy announced on August 14 that $5.1 million would go to the Electric Power Research Institute (EPRI) to develop modular-in-chamber electron beam welding capabilities to support reactor pressure vessel welding for NuScale Power’s small modular reactor design. The project has a total value of nearly $6.5 million, of which the DOE will provide about $5.1 million.

Web workshop: Separating nuclear reactors from the power block with heat storage
