Shellenberger

U.S. civil nuclear cooperation pacts—so-called 123 Agreements—are too strict, says Michael Shellenberger, founder and president of Environmental Progress, in an August 13 City Journal article.

Shellenberger reasons that the 123 Agreements force nations that have expressed interest in developing nuclear energy programs to turn to Russia and China. That result is bad, Shellenberger continues, not only for the American nuclear industry, but also for the global nonproliferation movement.

Crystal River-3 as it is now and how Duke Energy envisions the site will look by 2027.

The Florida Public Service Commission voted unanimously on August 18 to approve Duke Energy Florida’s plan to accelerate the decontamination and decommissioning of its Crystal River-3 nuclear power plant. The commission vote marks the final regulatory approval needed to finalize, in October, Duke Energy’s contract with Accelerated Decommissioning Partners (ADP). According to Duke Energy, ADP will complete the decommissioning by 2027, rather than the 2074 date that was originally announced.

Duke Energy permanently ceased operations at Crystal River-3 in 2013 and, in June 2019, the company applied to the Nuclear Regulatory Commission to transfer the reactor’s license to ADP, a joint venture of NorthStar Group Services and Orano Decommissioning Holdings. The NRC approved the license transfer in April. NorthStar will also be contracted to demolish the permanently shut down coal-fired Crystal River-1 and -2.

Tristructural isotropic (TRISO) coated particle fuel is a robust, microencapsulated fuel form developed originally for use in high-temperature gas-cooled reactors (HTGRs). The particles consist of a spherical fissile kernel surrounded by several layers of pyrocarbon and a silicon carbide (SiC) layer. The particles are formed into cylindrical or spherical fuel forms using a resinated graphite matrix material for insertion into an HTGR. The kernel and coating layers together act to retain fission products within the particle during normal reactor operation and during postulated accidents; TRISO particles can maintain structural integrity at extremely high temperatures, reaching as high as approximately 1,600 °C in limiting HTGR accidents. This limits the fission product activity circulating in the helium coolant and the activity released to the environment during accidents. Acceptable performance of TRISO particles is therefore essential for reactor safety.

Abilene Christian University (ACU) is leading a consortium called NEXTRA—the Nuclear Energy eXperimental Testing Research Alliance—with the Georgia Institute of Technology, Texas A&M University, and the University of Texas at Austin. NEXTRA was formed in spring 2019 to design, license, and commission a molten salt–fueled research reactor to be hosted on ACU’s campus in the central Texas city of Abilene. ACU and its partners recently announced funding of $30.5 million over the next three years from Abilene-based Natura Resources.

Van Hollen

Amid news stories of possible undeclared nuclear facilities in Saudi Arabia and China's involvement with them (see here and here, for instance), Sen. Chris Van Hollen (D., Md.) on August 19 led a bipartisan group of senate colleagues in sending a letter to President Trump requesting more information on the matter.

Cosigners included Sens. Rand Paul (R., Ky.), Jeff Merkley (D., Ore.), Susan Collins (R., Maine), Tim Kaine (D., Va.), and Jerry Moran (R., Kan.).

Pickering nuclear power plant

The government of Canada’s Ontario province is supporting a plan by Ontario Power Generation (OPG) to extend the life of the Pickering nuclear power plant, the province’s Ministry of Energy, Northern Development, and Mines announced recently. Currently, all six operating reactors at the facility, located in southern Ontario, are scheduled to close at the end of 2024.

Peters

Mark Peters has been named executive vice president of laboratory operations for Battelle, the company announced on August 20. He will take over for Ron Townsend, who earlier this summer announced that he plans to retire in January 2021. Peters, who has served as laboratory director at Idaho National Laboratory since October 2015, will remain in this role until his successor has been selected and is in place. He will assume his new role at Battelle following this transition at INL.

The Department of Energy is asking for input on an Energy Storage Grand Challenge (ESGC) Draft Roadmap and Request for Information (RFI) and recently extended the response deadline to August 31. While there is no “N” for nuclear in “ESGC,” nuclear is definitely part of the DOE’s plan for future energy storage technologies and integrated energy systems designed to improve the efficiency and reliability of U.S. energy markets. In fact, the House Energy and Water Appropriations Committee has called for $4 million in the Office of Nuclear Energy’s Fiscal Year 2021 budget to support energy storage.

Nawah Energy Company, in cooperation with the Abu Dhabi Transmission and Despatch Company (TRANSCO), has connected Unit 1 of the Barakah nuclear power plant to the United Arab Emirates’ power grid, according to an August 19 announcement from Nawah’s parent company, the Emirates Nuclear Energy Corporation (ENEC).

Barakah, located in the Al Dhafrah Region of Abu Dhabi, houses four 1,345-MWe APR-1400 pressurized water reactors. Unit 1 achieved first criticality earlier this month.

Horizon Nuclear Power is in talks with the U.K. government to revitalize plans to build the Wylfa Newydd nuclear power plant in northwestern Wales, the Financial Times reported last week.

The American Nuclear Society has formed a Task Force on Public Investment in Nuclear Research and Development to assess the R&D needs of the U.S. nuclear technology enterprise and the federal investment required to meet those needs. The task force will identify the overarching objectives of U.S. nuclear R&D and identify specific metrics that can be used to evaluate progress toward those objectives.

With the Democratic Convention now under way, it is good to remember that all the leading climate scientists say that we cannot address climate change without significant nuclear power, Jim Conca noted in his opinion column on the Forbes blog site. Supporting nuclear power - or not - is a clear signal about how serious a candidate is about climate change and supporting science over mere activism, Conca said.

Finnish energy company Fortum Power and Heat Oy has initiated an environmental impact assessment procedure for the two reactors at its Loviisa nuclear power plant with the aim of operating the units for 20 years beyond their current license expiration dates of 2027 (for Unit 1) and 2030 (for Unit 2).

The Department of Energy approved the start of operations at the Salt Waste Processing Facility (SWPF) at the Savannah River Site (SRS), authorizing hot (radioactive) operations to begin at the facility, the agency announced on August 17.

The approval comes five months ahead of the current baseline completion date of January 31, 2021. Parsons Corporation, which designed and built the first-of-a-kind facility, will operate it for one year.

“This is a considerable achievement for EM's (Environmental Management) cleanup program and will drive significant progress in treating the tank waste at SRS in the next decade,” said William “Ike” White, senior advisor for the EM to the Under Secretary for Science.

Pompeo

Morawiecki

While the Enhanced Defense Cooperation Agreement grabbed more attention, it was not the only U.S.-Poland pact inked in Warsaw last week. The two countries also initialed a draft bilateral agreement to cooperate in the development of Poland’s civil nuclear power program, according to the State Department. Secretary of State Mike Pompeo met with Polish Prime Minister Mateusz Morawiecki on August 15 to discuss the partnership, in addition to other matters including the improvement of regional energy and infrastructure through the Three Seas Initiative, the department said.

The National Commission on Grid Resilience (NCGR) has released a report recommending a series of actions to better address threats to the bulk power system in the United States. While noting that “substantial progress has been made in a short time” toward improving grid resilience, the report declares that “more needs to be done, and in record time.”

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.

The Department of Energy established the Consortium for Advanced Simulation of Light Water Reactors (CASL) at Oak Ridge National Laboratory in 2010 as a national collaboration of government, academia, and industry to help the nuclear industry extend the life of the current reactor fleet and develop more efficient next-generation reactors. On August 13, ORNL issued a news release and video to celebrate the achievements of CASL, which concluded its mission in June.

Stars contain their plasma with the force of gravity, but here on earth, plasma in fusion tokamaks must be magnetically confined. That confinement is tenuous, because tokamaks are subject to edge localized modes (ELM)—intense bursts of heat and particles that must be controlled to prevent instabilities and damage to the fusion reactor.

Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and at General Atomics (GA) recently published a paper in Physical Review Letters explaining this tokamak restriction and a potential path to overcome it. They have developed a new model for ELM suppression in the DIII-D National Fusion Facility, which is operated by GA for the DOE. PPPL physicists Qiming Hu and Raffi Nazikian are the lead authors of the paper, which was announced on August 10 by PPPL.
