Doane

Margaret Doane, the first female executive director for operations at the Nuclear Regulatory Commission, will depart the agency on October 8 to take the position of deputy director general for management at the International Atomic Energy Agency, the NRC announced this morning.

Doane, who has been the NRC’s EDO since July 2018, began her career at the agency in 1991 as a special assistant in the Office of the Secretary. Her senior leadership roles have included serving as an attorney in the Office of Commission Appellate Adjudication, chief of staff for former commissioner Jeffrey Merrifield, and NRC general counsel—a position she held from 2012 to 2018. Doane has international experience as well, having served in the Office of International Programs, both as deputy director and director.

A high-temperature superconducting magnet reached and maintained a magnetic field of more than 20 tesla in steady state for about five hours on September 5 at MIT’s Plasma Science and Fusion Center. Not only is the magnet the strongest high-temperature superconducting (HTS) magnet in the world by far, it is also large enough—when assembled in a ring of 17 identical magnets and surrounding structures—to contain a plasma that MIT and Commonwealth Fusion Systems (CFS) hope will produce net energy in a compact tokamak device called SPARC in 2025, on track for commercial fusion energy in the early 2030s.

With only days remaining before the scheduled retirement of Exelon Generation’s Byron nuclear plant, the Illinois House has approved a comprehensive energy package (S.B. 2408) that would save the plant, as well as the state’s similarly struggling Braidwood and Dresden facilities.

With only days remaining before the scheduled retirement of Exelon Generation’s Byron nuclear plant, the Illinois General Assembly may be close to passing a comprehensive energy package (S.B. 2408) that would save that plant, as well as the state’s similarly struggling Braidwood and Dresden facilities.

House Democrats have introduced an amendment to S.B. 2408 that would require municipally owned coal plants to achieve a 45 percent reduction in greenhouse gas emissions by 2035 and completely phase out coal by 2045. The House is considering the amendment today.

(Financial assistance to Illinois’s nuclear fleet is part of a package that for weeks has been mired in disagreement between unions and environmental groups over the fate of the state’s coal plants.)

U.S. energy secretary Jennifer Granholm and Ukrainian energy minister Herman Galushchenko last week signed a joint statement of intent to advance energy and climate cooperation through the U.S.-Ukraine Strategic Energy and Climate Dialogue. The signing took place during a visit to Washington, D.C., by Ukrainian president Volodymyr Zelensky for meetings with President Biden at the White House.

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.

As part of a fellowship program between the Department of Energy’s Office of Environmental Management and Florida International University, a group of FIU students participated in a summer internship initiative called the Science and Technology Workforce Development Program. The program is run in conjunction with Washington River Protection Solutions (WRPS), the Hanford Site’s tank operations contractor in Washington state.

Nuclear power plants around the world generated 2,553 TWh of electricity in 2020, a drop of 104 TWh from 2019’s total, according to World Nuclear Performance Report 2021. The report was released last week by the U.K.-based World Nuclear Association.

Nuclear generation declined in Africa, North America, and Western and Central Europe, rose in Asia (but by much less than in recent years), and remained largely unchanged in Eastern Europe, South America, and Russia, the 68-page report states.

Sama Bilbao y León, WNA director general, notes in the report’s preface that although the nearly 4 percent decline “would be an unequivocal disappointment” in any other year, “in 2020, with overall electricity demand falling by around 1 percent and nuclear reactors increasingly being called upon to provide load-following support to the increased share of variable renewable generation, the resilience and flexibility shown by the global nuclear fleet tell a very positive story.”

In the aftermath of a devastating explosion in the port of Beirut, Lebanon, in August 2020, an International Atomic Energy Agency team visited the country at the government’s request and found no evidence of artificial radionuclides and no increase in radiation levels. The powerful blast, which was caused by an explosion of improperly stored ammonium nitrate, killed more than 200 people and leveled numerous buildings while leaving other buildings standing with possible structural damage. The IAEA recently announced that a different team of experts has traveled to Lebanon with a new mission: to assist the nation in the use of non-destructive testing (NDT) to check the structural soundness of buildings that were impacted by the explosion.

In an action that could make Pennsylvania’s nuclear plants more cost-competitive in power markets, the state’s Independent Regulatory Review Commission has approved a regulation that would allow Pennsylvania to join the Regional Greenhouse Gas Initiative (RGGI), a cooperative effort of Northeastern and Mid-Atlantic states designed to cap and reduce carbon emissions from fossil fuel–fired power plants.

The Center for Advanced Energy Studies (CAES) has announced the opening of the Small Modular Reactor Simulator Laboratory, featuring NuScale Power’s Energy Exploration Center, at its headquarters in Idaho Falls, Idaho. The new lab will increase CAES’s capabilities to train future scientists, engineers, and members of the energy workforce and will be used to educate the public about nuclear energy and reactor technology, according to an August 31 CAES press release.

The U.S. Department of Energy and Norway’s Ministry of Trade, Industry, and Fisheries have signed a memorandum of understanding to advance a project aimed at eliminating Norway’s high-enriched uranium by downblending it to low-enriched uranium. If the project is successfully completed, Norway will become the 34th country (plus Taiwan) to be considered HEU-free.

In the downblending process, HEU is mixed with depleted or natural uranium to reduce the U-235 concentration to below 20 percent, resulting in LEU, which cannot be used to make an improvised nuclear device (aka “dirty bomb”). According to the DOE’s National Nuclear Security Administration, the challenge with Norway’s HEU has been that much of it is mixed with thorium, making the use of other disposition techniques more problematic.

A closer look: Signed on September 1 by U.S. energy secretary Jennifer Granholm and her Norwegian counterpart, Iselin Nybø, minister of trade and industry, the MOU calls for small-scale downblending activities to begin in 2022 using Norway’s existing infrastructure. It also paves the way for the eventual deployment of the DOE’s Mobile Melt-Consolidate system to complete the work.

The Department of Energy’s National Nuclear Security Administration has launched a radiological security project known as the RadSecure 100 Initiative. The initiative will focus on removing radioactive material from facilities (where feasible) and improving security at the remaining facilities located in 100 metropolitan areas throughout the United States. It includes a partnership with local law enforcement.

The initiative is being announced this week by the NNSA during the National Homeland Security Conference in Las Vegas.

A list of the 100 U.S. cities where the initiative will be enacted is available online.

Westinghouse Electric Company has entered into a cooperation agreement with the Department of Justice in connection with its role in the failed effort to build two AP1000 reactors at the Summer nuclear plant in Jenkinsville, S.C.

With essentially no time to spare, the Illinois Senate early this morning passed a clean energy omnibus package that includes $694 million in assistance to three of the state’s financially troubled nuclear plants: Braidwood, Byron, and Dresden. The vote was 39–16. (Both the Senate and House had returned to the capital on Tuesday for a one-day special session to consider legislative redistricting.)

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.

Inside the ITER Assembly Hall, aided by a 20-meter-tall sector subassembly tool known as SSAT-2, the first of nine 40-degree wedge-shaped subassemblies that will make up the device’s tokamak is taking shape. On August 30, the ITER Organization announced that all the components of the first subassembly were in place on the SSAT-2. After the wings of the subassembly tool slowly close, locking two vertical coils in place around the outside of a vacuum vessel section that is already wrapped in thermal shielding, the completed subassembly will be ready for positioning in the ITER assembly pit in late October.

The Nuclear Regulatory Commission’s draft environmental impact statement on Dominion Energy’s application for a subsequent license renewal (SLR) for North Anna’s nuclear units is now open for public comment.

Yesterday morning with about two weeks to go before the scheduled permanent closure of Illinois’s Byron nuclear power plant, state Sen. Michael Hastings (D., 19th Dist.) filed a proposal to end the state legislature’s stalemate on a clean energy package that would, among other things, provide financial aid to Byron, as well as to other endangered nuclear power facilities in the state, via a carbon mitigation credit program.

Oversight of the Vogtle nuclear new-build project will be increased if the preliminary conclusions in an August 26 Nuclear Regulatory Commission special inspection report are finalized.

Conducted from June 21 to July 2, the inspection looked into the cause and extent of construction-quality issues in the safety-related electrical cable raceway system at Vogtle-3.
