According to ETO Insider, the Federal Energy Regulatory Commission this week dismissed a complaint filed in October 2020 from Californians for Green Nuclear Power (CGNP) against multiple agencies regarding the closing of Pacific Gas and Electric’s Diablo Canyon nuclear power plant.

In denying the complaint on technical grounds against the California Independent System Operator (CAISO), FERC said that CGNP had “not met its burden under Section 206 of the Federal Power Act.” The remaining complaints against North American Electric Reliability Corporation (NERC), Western Electricity Coordinating Council (WECC), the California Public Utilities Commission (CPUC), the California State Water Resources Control Board (CSWRCB), and California State Lands Commission (CSLC) were dismissed on the grounds that they “are not proper respondents.”

In a program sponsored by the National Nuclear Security Administration’s Office of Defense Nuclear Nonproliferation, teams of engineering students from Washington State University designed, built, and delivered prototype equipment to address challenges encountered by Pacific Northwest National Laboratory staff in research on nuclear safeguards.

As reported on March 11 by the NNSA, two teams of WSU students presented their projects to PNNL staff during an online meeting in December 2020. One team created physical training aids for safeguards courses to demonstrate two methods of nuclear fuel reprocessing. The other team developed an enrichment monitor mounting bracket that the International Atomic Energy Agency could use to help monitor uranium hexafluoride gas in enrichment facilities.

Join the American Nuclear Society on Friday, March 26, from 1 p.m. to 2 p.m. (EDT) to hear perspectives on the future of nuclear energy offered by individuals who have played a significant role in framing the United States’ nuclear energy policies of the past, present, and future.

Holtec International said that it successfully loaded its 1,500th spent fuel canister last week as part of the ongoing dry storage campaign at Ameren Missouri’s Callaway Energy Center. Holtec’s HI-STORM UMAX subterranean dry storage system has been in service at Callaway since 2015. The MPC-37 multipurpose canister is used to place 37 pressurized water reactor spent fuel assemblies into each HI-STORM UMAX vertical ventilated module.

“There has been a strong collaboration between our teams, and I truly appreciate the strong focus on doing the work safely, correctly, and to the highest standards of excellence,” said Fadi Diya, senior vice president and chief nuclear officer of Ameren Missouri, in a March 17 announcement.

“Just as we shared the milestone in 2015 of deploying the world’s first subterranean dry storage system under a general license, we are proud to share this milestone with Ameren,” said Pierre Oneid, Holtec’s senior vice president and chief nuclear officer.

The Department of Energy on March 16 announced $18 million in new particle accelerator technology funding that includes $5 million for university-based traineeships for accelerator scientists and engineers.

Accelerating solutions: Beams of charged particles are powerful tools for scientific research, and particle accelerators have also been used in medical imaging and cancer therapy, in the manufacturing of semiconductors, and as a nonchemical method of destroying pathogens and toxic chemicals.

In response to House Democrats’ introduction on March 2 of a massive energy bill, the CLEAN Future Act, Republicans on the House Energy and Commerce Committee have unveiled their own, more modest energy agenda—a package of existing legislation that they say would “secure America’s energy future and global competitive edge against China.”

McMorris Rodgers

According to a March 15 press release from the committee’s ranking member, Rep. Cathy McMorris Rodgers (R., Wash.), along with Reps. Fred Upton (R., Mich.) and David McKinley (R., W.Va.), the GOP plan will address climate change risks and spur the development and deployment of clean energy infrastructure without the “pie-in-the-sky” mandates, regulations, and federal government spending advocated by the Democrats.

What they’re saying: “This package will modernize and improve our energy infrastructure and promote an all-of-the-above energy strategy across the board, including solutions to unleash innovation in hydropower, nuclear, clean coal, and natural gas,” the Republican lawmakers state. “These are real, workable solutions to make energy cleaner, reduce emissions, prioritize energy security, and keep energy costs low.”

Shellenberger

In testimony last Thursday before the Senate Committee on Energy and Natural Resources, Michael Shellenberger, founder and president of Environmental Progress, called for maintaining the current U.S. fleet of nuclear power reactors. He argued that the premature closure of nuclear plants threatens the reliability, resiliency, and affordability of the nation’s electricity supply, as well as its ability to reduce carbon emissions.

Without state or federal action, 12 reactors will close by 2025, resulting in the loss of 10.5 GW of “highly reliable, low-cost, and low-carbon power,” Shellenberger noted in his written statement. He added, “If those nuclear plants are lost, grids may suffer from energy shortages during future heat waves or cold snaps.”

Advanced reactor development and testing could benefit from a Pacific Northwest National Laboratory innovation that combines remote, real-time monitoring of gaseous fission by-products with a software package designed with plant operators in mind, according to an article published online earlier this month.

The basics: “Real-time monitoring is a valuable tool, particularly in the development of next-generation reactors,” said Amanda Lines, a PNNL chemist. “This can help designers more efficiently and effectively design and test flow loops, mechanisms, or processes. Also, when they ultimately deploy their reactor systems, this gives operators a tool to better understand and control those processes.”

COVID-19 has touched our lives in many ways, affecting work, school, and homelife. The Diversity and Inclusion in ANS Committee is holding a free webinar, "Coping with COVID: The Pandemic and the Nuclear Community," on Tuesday, March 23, from 1:00 p.m. to 2:30 p.m. (EDT).

Panelists will discuss how the nuclear community is responding to the pandemic, what more can be done, what support resources are available, and what the future looks like.

Registration is required for the webinar.

The signing last October of a bilateral agreement between the United States and Poland to cooperate on the latter’s civil nuclear power program appears to be bearing fruit. On March 15, following a meeting in Warsaw between Patrick Fragman, president and chief executive officer of Westinghouse Electric Company, and Piotr Naimski, Poland’s secretary of state for strategic energy infrastructure, Westinghouse announced its intention to invest in nuclear technologies in Poland.

The agreement, which entered into force earlier this month, calls for the United States and Poland to cooperate over the next 18 months on a report laying out a plan for implementing Poland’s nuclear power program, as well as potential financing arrangements. It also defines areas of U.S.-Polish cooperation for decades to come, including support for relevant business entities and government-led efforts ranging from regulation to research and training to supply chain development.

Researchers at Texas A&M University have recently demonstrated the superior performance of a new oxide-dispersion-strengthened (ODS) alloy developed for use in both fission and fusion reactors.

Shao

Lin Shao, a professor in the university’s Department of Nuclear Engineering and an ANS member, worked alongside research scientists at Los Alamos National Laboratory and Hokkaido University to create the next generation of high-performance ODS alloys. So far, the researchers reported, the alloys are some of the strongest and best-developed metals in the field.

Details of the project were published in the February 2021 issue of the Journal of Nuclear Materials.

Southern California Edison has released a three-volume set of plans supporting the off-site relocation of the spent nuclear fuel currently stored at the San Onofre Nuclear Generating Station. According to SCE, the release of the Action Plan, the Strategic Plan, and the Conceptual Transportation Plan constitutes a significant milestone in a process that began with the 2017 settlement regarding the coastal development permit issued for San Onofre’s expanded spent fuel storage installation.

At the same time, in an effort to urge the federal government to find a permanent solution to the nation’s inventory of commercial spent fuel, SCE and the counties of Orange and San Diego announced on March 15 the formation of a stakeholder coalition, Action for Spent Fuel Solutions Now.

“SCE and our partners and stakeholders have a genuine opportunity to bring people together with a shared interest to prepare and advocate for the relocation of the spent fuel away from the coast,” said Kevin Payne, SCE’s president and chief executive officer. “It is clear that to make tangible progress on this issue, the federal government must act. Rather than wait for this to happen, we are going to be a catalyst for change.”

Information about the coalition, including how to join, is available on its website.

Work crews have demolished the High Flux Beam Reactor (HFBR) exhaust stack at Brookhaven National Laboratory, on Long Island, N.Y., the Department of Energy’s Office of Environmental Management (EM) reported last week.

The 320-foot-tall red-and-white stack was decommissioned and demolished under the direction of the DOE, with oversight by the U.S. Army Corps of Engineers.

Demolition work: Removal of the stack started in early January using a concrete chimney demolition system called the MANTIS. Work crews dismantled the stack down to its base, about 36 feet above ground, before fully demolishing it in late February.

The next steps for the project are the cleanup of soils, the removal of the below-ground stack infrastructure, and verification that cleanup goals have been met. The Oak Ridge Institute for Science and Education will conduct independent verification of the stack cleanup, according to the DOE.

The first rail shipment of the stack’s debris to off-site disposal will involve 65 intermodal waste containers loaded onto a 10-railcar train. About 45 additional containers are expected to be shipped as part of the second and final waste shipment.

The Ohio House of Representatives has voted to rescind the nuclear subsidy provisions of H.B. 6, the controversial 2019 piece of legislation that has been marinating in scandal since last July. Just one week earlier, a similar measure was passed unanimously in the Ohio Senate.

Approved by a tally of 86-7 on March 10, H.B. 128 strips H.B. 6 of subsidies for Energy Harbor’s Davis-Besse and Perry nuclear plants, as well as a “decoupling” provision that would have been of substantial financial benefit to FirstEnergy Corporation, the former parent company of Energy Harbor. The new bill retains H.B. 6’s subsidies for utility-scale solar projects, however, and for two coal plants (one in Ohio, one in Indiana).

H.B. 128 was sponsored by Reps. James Hoops (R., Dist. 81) and Dick Stein (R., Dist. 57).

Along with many other media outlets on March 11, the PBS NewsHour reported on the continuing recovery efforts from the earthquake and tsunami that devastated northeastern Japan 10 years ago. The segment, "Japan marks 10th anniversary of Fukushima nuclear disaster," is just over eight minutes long, most of which discusses the effects of the earthquake and tsunami on the region and Japan’s preparedness for the next major natural incident.

A new technical report from Montreal-based SNC-Lavalin finds Canada’s stated goal of net-zero carbon emissions by 2050 to be achievable but stresses the importance of immediate action and investment in all forms of low-carbon energy production, including nuclear, hydro, renewables, carbon capture and storage, and hydrogen.

According to the 100-page document, Engineering Net Zero, Canada needs to triple its power production levels over the next 30 years, as forecasts show demand growing from 500 TWh to 1,500 TWh.

A 28-page executive summary of the report is available online.

A method developed at Oak Ridge National Laboratory is allowing the Department of Energy to cull promethium-147 from plutonium-238 produced for space exploration. Under an ORNL project for the DOE Isotope Program that began last year, the lab has been mining Pm-147, a rare isotope used in nuclear batteries and to measure the thickness of materials, from the fission products left when Pu-238 is separated out of neptunium-237 targets. The Np-237 targets are irradiated in Oak Ridge’s High Flux Isotope Reactor, a DOE Office of Science user facility, to produce the Pu-238.

According to the DOE, the primary goal of the project is to reestablish the domestic production of Pm-147, which is in short supply. As a side benefit, the project is reducing the concentrations of radioactive elements in the waste so that it can be disposed of safely in simpler, less expensive ways, both now and in the future.

“In the process of recovering a valuable product that the DOE Isotope Program wants, we realized we can reduce our disposal costs,” said Richard Mayes, group leader for ORNL’s Emerging Isotope Research. “There’s some synergy.”

After years of litigation, Germany has reached an agreement with four utility companies on compensation for losses incurred as a result of the government’s stunning decision in 2011 to abandon nuclear power. In March of that year, only days after the Fukushima Daiichi disaster, German Chancellor Angela Merkel announced a 180-degree reversal in the country’s energy policy, which had been one of support for nuclear power. Eight units were shut down immediately, and by May 2011 the government had announced a plan to close all nuclear power plants by 2022.

The companies will receive a total of €2.4 billion (about $2.85 billion), with €1.4 billion going to Sweden-based Vattenfall and the remaining €1 billion split between German utilities RWE (€880 million), EnBW (€80 million), and E.ON (€42.5 million). In return, the companies have agreed to terminate all phaseout-related legal disputes with the government.

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.

Eiler

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.
