The OECD Nuclear Energy Agency is offering the first International School on Simulation of Nuclear Reactor Systems (SINUS) workshop in May this year, with the topic “Reactor Single- and Multi-Physics Simulations Based on Light Water Reactor (LWR) Uncertainty Analysis in Modeling (UAM) Benchmark.”

Registration for the workshop is available online.

The Canadian Nuclear Safety Commission (CNSC) and Poland’s National Atomic Energy Agency (PAA) have signed a memorandum of cooperation to share best practices and experience in reviewing advanced and small modular reactor technologies. (The two agencies are already engaged in cooperation on nuclear safety matters under a memorandum of understanding inked in 2014.)

The Nuclear Waste Informed Consent Act was reintroduced in the U.S. House of Representatives last week by Rep. Dina Titus (D., Nev.). Previous iterations of the bill, designed to prevent the federal government from reviving the Yucca Mountain nuclear waste repository project, have all died in congressional committees.

The bicameral legislation, led by Sen. Catherine Cortez Masto (D., Nev.), would require the secretary of energy to obtain the consent of affected state, local, and tribal governments before making an expenditure from the Nuclear Waste Fund for a nuclear waste repository. The bill is being cosponsored by Sen. Jacky Rosen (D., Nev.) and Reps. Steven Horsford (D., Nev.) and Susie Lee (D., Nev.).

The bipartisan Nuclear Fuel Security Act (NFSA), introduced in the Senate last week, would authorize the Department of Energy to establish a Nuclear Fuel Security Program to “ensure a disruption in Russian uranium supply would not impact the development of advanced reactors or the operation of the United States’ light water reactor fleet.” The bill was introduced by Sen. Joe Manchin (D., W.V.), chairman of the Senate Energy and Natural Resources (ENR) Committee; Sen. John Barrasso (R., Wyo.), ranking member of the Senate ENR committee; and Sen. Jim Risch (R., Idaho).

Used nuclear fuel and high-level radioactive wastes are by-products of nuclear energy production and other applications of nuclear technology, and the consensus approach to disposing of those wastes safely is to encapsulate them and emplace them in stable geologic formations (geologic repositories) where they will be isolated from people and the environment for very long periods of time. The federal government has established environmental standards for waste isolation that any proposed geologic repository must meet.

In July 2021, the American Nuclear Society established a special committee to consider possibilities for revised generic environmental standards for disposal of spent nuclear fuel and high-level radioactive waste in the United States. The committee developed a number of recommendations, which are contained in a draft report that was to be issued in February for review and comment by stakeholders. The draft report can be found on the ANS website, at ans.org/policy/repositorystandard/.

The committee’s draft recommendations are based on two underlying assumptions. First, that the relevant legislative framework for regulation defined in the Nuclear Waste Policy Act (NWPA) remains unchanged. Specifically, it is assumed that the Environmental Protection Agency will be charged with promulgating environmental standards for disposal and that the Nuclear Regulatory Commission will be charged with reviewing applications for disposal facilities using licensing requirements and criteria consistent with the EPA standards. Second, that existing generic disposal standards will be updated or replaced.

In March 1949, the Atomic Energy Commission selected a site in Idaho for the National Reactor Testing Station (NRTS), known today as Idaho National Laboratory. Idaho’s Snake River Plain was selected because of the rural nature of southern Idaho. The site would go on to be the most remarkable proving ground for today’s nuclear industry. Experiments at this world-class facility have continually paved the way for nuclear innovation.

Already for the second time this year, Southern Company has announced a delay to the expected commercial operation of Unit 3 at the Vogtle nuclear plant’s two-unit construction site. In addition, a delay to Unit 4’s startup is also possible, Southern said.

The National Governors Association (NGA) yesterday announced that it has formed a bipartisan working group in anticipation of funding for state energy and infrastructure projects from the $1.2 trillion Infrastructure Investment and Jobs Act, signed into law by President Biden last November.

While still lacking a deep geological repository for the permanent disposal of its commercial used nuclear fuel and high-level radioactive waste, the United States does have regulatory standards for geological nuclear waste disposal.

Having been written nearly 40 years ago, however, those standards are outmoded and lack transparency, according to a special committee of the American Nuclear Society, which has released draft recommendations on revising public health and safety standards for future geological repository projects in the United States.

The Nuclear Regulatory Commission has approved a plan by United Nuclear Corp. (UNC) to dispose of mine waste from the Northeast Church Rock mine site in New Mexico at the company’s nearby uranium mill and tailings disposal site.

Commonwealth Fusion Systems (CFS) hosted visiting officials for a tour and ribbon-cutting ceremony to officially open its new headquarters in Devens, Mass., on February 10. Energy secretary Jennifer Granholm, Sen. Elizabeth Warren (D., Mass.), and Sen. Edward Markey (D., Mass.) were among the national, state, and local leaders invited to celebrate what CFS heralded as a “fusion energy campus.”

Two large tanks near the Effluent Treatment Facility (ETF) at the Department of Energy’s Hanford Site in Washington state were removed recently to make way for future wastewater treatment activities at the ETF.

O'Quinn

Nuclear Newswire erroneously reported this morning that the Virginia Senate’s Finance and Appropriations Committee on February 15 advanced legislation that included nuclear in a list of energy technologies that would receive research and development funding through a Virginia Power Innovation Fund. In fact, the bill, H.B. 2386, was approved after the committee had stripped nuclear from the list. NN regrets the error.

Following the finance panel’s vote, Del. Israel O’Quinn (R., 5th Dist.), the bill’s sponsor, expressed his disappointment. “The knee-jerk opposition to nuclear innovation is very short-sighted and puts Virginia behind the curve on energy diversification,” he said. “Nuclear energy is inevitably going to have to be a bigger part of Virginia’s energy portfolio. It produces zero carbon and is highly reliable.”

Entergy’s River Bend nuclear power plant started its 22nd scheduled refueling and maintenance outage on February 11. The plant, located in St. Francisville, La., is a 967-MWe General Electric boiling water reactor.

As if being stuck in the middle of a combat zone isn’t sufficiently nerve-racking, workers at Ukraine’s Zaporizhzhia nuclear power plant—under Russian occupation since last March—must now concern themselves with having access to enough water to keep the facility safe.

The Defense Waste Processing Facility (DWPF) at the Department of Energy’s Savannah River Site (SRS) in South Carolina has resumed operations after a completing a processing improvement that the DOE said will enable safer operations and more efficient vitrification of radioactive waste.

Nick Touran

I got into nuclear engineering when I realized I could apply my passion for computers to the critical human challenge of energy. After training, I spent the past 13-plus years building automated and integrated engineering analysis tools for the efficient design/licensing of advanced nuclear reactors. Given what I’ve seen, I expect that modern high-level programming languages and data systems will continue to enable new efficiencies in analysis, configuration management, work planning, procurement, training, compliance, and execution in operations. The magnitude of potential impact laid out, for example, in Information Technology for Nuclear Power Plant Configuration Management (IAEA-TECDOC-1651) is well within reach. These impacts are identical to those promised by digital twins. Achieving these goals will require more information workers in the offices of nuclear vendors and operators to develop sophisticated skills in software engineering, database administration, statistics, and business analytics. Additionally, decision makers must be better trained to best understand and choose specialized IT systems and software.

Salado Isolation Mining Contractors (SIMCO), a single-purpose entity comprised of Bechtel National and Los Alamos Technical Associates as a teaming contractor, has assumed responsibility for managing and operating the Waste Isolation Pilot Plant in New Mexico.

The United States is supporting a junior professional officer (JPO) position in the International Atomic Energy Association to work on spent nuclear fuel management. The role is for an associate project officer-spent fuel management, who will be based in Vienna, Austria, and work under the direct supervision of the technical leader of the spent fuel management team in the Division of Nuclear Fuel Cycle and Waste Technology.

The Nuclear Regulatory Commission has updated its guidance for nuclear power plant owners and operators in estimating the cost of decommissioning their reactors. Licensed power reactor operators are required under NRC regulations to annually adjust the estimated costs (in current-year dollars) of decommissioning their plants to ensure that adequate funds are available when needed.
