A new report from the American Institute of Physics declares the physical sciences to be at a “tipping point” between a “perilous” future and a “vibrant” one as a result of the coronavirus pandemic. The 28-page report, Peril and Promise: Impacts of the COVID-19 Pandemic on the Physical Sciences, outlines several areas where the scientific community has been tested by the pandemic and examines what the future could look like for the workforce, infrastructure, and conduct of research. Further, the report challenges leaders in government, academia, the private sector, and other areas who depend on the physical sciences to craft specific recommendations to address the pandemic’s impacts.

The International Atomic Energy Agency has initiated a crowdsourcing competition for innovative ideas to boost the competitiveness of nuclear power plants, the agency announced on July 3. The deadline is August 15 for the submission of abstracts, which should be based on practices already in place at plants. Chosen participants will be invited to present their ideas at the annual Nuclear Operators’ Forum, to be held during the IAEA’s 64th IAEA General Conference, scheduled for September 21–25 in Vienna.

Preparations have begun for the construction of four nuclear reactors in Russia—two VVER-1200 units at the Leningrad plant and two VVER-TOI units near the Smolensk plant, according to Rosenergoatom, a division of Russia’s state-owned atomic energy corporation Rosatom.

Rosenergoatom operates all of Russia’s nuclear power facilities. Authorization to move forward with the new-build projects was signed by Alexey Likhachev, Rosatom’s director general.

BWX Technologies has signed a $26-million, 20-month contract to expand and upgrade its TRISO fuel manufacturing line. The recently announced deal, awarded by Idaho National Laboratory, calls for the expansion of BWXT’s capacity for the manufacture of TRISO fuel compacts and the upgrading of existing systems for delivering production-scale quantities of TRISO fuel.

The House Appropriations Committee yesterday released a draft of the fiscal year 2021 Energy and Water Development and Related Agencies appropriations bill, calling for higher levels of funding for nuclear energy. The legislation would fund activities at the Departments of Energy and Interior, the U.S. Army Corps of Engineers, and a number of related agencies, including the Nuclear Regulatory Commission and the Defense Nuclear Facilities Safety Board.

The United Kingdom’s Office for Nuclear Regulation (ONR) on June 30 received a nuclear site license application from EDF Energy subsidiary NNB Generation Company (SZC) Limited to construct and operate two reactors at the Sizewell site in the county of Suffolk, northeast of London.

A new report from the Paris-based OECD Nuclear Energy Agency declares that nuclear power is needed for countries to meet their Paris Agreement decarbonization and energy security policy goals, but that governmental support for a rapid reduction in the cost of new nuclear capacity through the creation of certain policy frameworks is likely necessary.

We often define noise as an unwanted disturbance, especially acoustic in nature. Neutron noise, by contrast, is a direct measure of the dynamics of a nuclear core. It can be used for core monitoring without disturbing plant operation and by using the existing core instrumentation. The European CORTEX project aims to develop an innovative core monitoring technique using neutron noise, while capitalizing on the latest developments in neutronic modeling, signal processing, and artificial intelligence.

With a new generation of nuclear reactors in the works, Idaho National Laboratory has embraced digital engineering (DE) as a means of achieving the same efficiencies that companies in the private sector have been able to realize in everything from concert halls to aircraft engines.

DE—using advanced technologies to capture data and craft design in a digitized environment—has been evolving since the 1990s. For Mortenson Construction, a worldwide construction firm, using virtual design and construction resulted in a cumulative 600 days saved over 416 projects and a 25 percent increase in productivity. By building digital twins for assets, systems, and processes, DE has avoided more than $1.05 billion in customer, production, and mechanical losses.

Leaders at INL recognized in 2018 that DE could be useful in the design and construction of new commercial and test reactors. Managing construction costs, timing, and performance will be essential to maintain U.S. competitiveness.

U.S. Sens. Lisa Murkowski (R., Alaska), chairman of the Senate Energy and Natural Resources Committee, and Joe Manchin (D., W.Va.), the committee’s ranking member, put their rhetorical skills to the test earlier this week as the two urged colleagues to pass the American Energy Innovation Act (AEIA), a comprehensive piece of energy policy legislation introduced by the bipartisan pair in late February (NN, Apr. 2020, p. 14).

House Democrats on June 30 rolled out a vision of what U.S. climate change policy might look like in the event the Democratic party holds its current House majority, retakes the Senate, and wins the White House in November. The vision was presented in the form of a sweeping 547-page majority staff report entitled Solving the Climate Crisis: The Congressional Action Plan for a Clean Energy Economy and a Healthy, Resilient, and Just America.

The Nuclear Regulatory Commission has announced a notice of opportunity to intervene in an adjudicatory hearing on Oklo Power’s combined license application (COLA) for construction of a microreactor at Idaho National Laboratory. The notice, dated June 24, was published in the Federal Register on June 30, opening a 60-day window for petitions.

After producing electricity generation for more than 40 years, Fessenheim-2 was disconnected from the grid on June 29, some four months after the retirement of its companion reactor, Fessenheim-1 (NN, Mar. 2020, p. 83). The action completes the closure of what had been France’s oldest operating nuclear power facility.

Both Fessenheim units are 880-MWe pressurized water reactors; Unit 1 began commercial operation in December 1977, with Unit 2 going on line in March 1978.

The International Atomic Energy Agency has signed an agreement with Japan’s Okayama University that provides a three-year framework for enhanced cooperation in boron neutron capture therapy (BNCT), the IAEA announced on June 24. BNCT is a noninvasive therapeutic technique for treating invasive malignant tumors.

The International Atomic Energy Agency has released nuclear power status data for 2019 collected by the Power Reactor Information System (PRIS), the IAEA’s comprehensive nuclear power database. Developed and maintained by the IAEA for more than five decades, PRIS contains historical and current quantitative information on reactors in operation and under construction, as well as on units undergoing decommissioning.

Now available from the World Nuclear Association is an expanded summary of its latest Nuclear Fuel Report, published last September. According to the WNA, “This expanded summary will provide readers with explanations of what factors are affecting the growth of nuclear power, what new concepts were introduced in the 19th edition, and what developments the industry may require between now and 2040.”

The International Atomic Energy Agency has emphasized that elevated concentrations of cesium-134, cesium-137, and ruthenium-103 recently detected over Northern Europe pose no risk to human health or the environment, even as the agency continues to investigate their origin.

The government of Canada’s Saskatchewan province has unveiled plans to establish an office to coordinate nuclear policy and program work. The office, dubbed the Nuclear Secretariat, will have as its primary mission to develop and execute a strategic plan to deploy small modular reactors, according to a June 24 press release. The secretariat will be housed within the Climate Change and Adaptation Division of Saskatchewan’s Ministry of Environment.

A team of researchers at the Department of Energy’s Oak Ridge and Argonne national laboratories has performed the first room-temperature X-ray measurements on the SARS-CoV-2 main protease, the enzyme that enables the virus to reproduce.

The X-ray measurements mark an important first step in the researchers’ ultimate goal of building a comprehensive 3D model of the enzymatic protein.

The Paris-based Nuclear Energy Agency recently issued four policy briefs on the role that nuclear energy can play in the post-COVID-19 recovery:
