The Nuclear Regulatory Commission announced on August 2 that it had issued a confirmatory order to the National Institute of Standards and Technology (NIST) for violating NRC requirements during a February 2021 fuel failure at the 20-MWt NIST Center for Neutron Research (NCNR) research reactor in Gaithersburg, Md. NIST committed to improving its training for fuel handing procedures and related management activities, safety culture program, reactor facility operations staff and management, corrective action program and operational procedures, and emergency response resources and procedures, among other things.

Last Energy, a Washington, D.C.–based small modular reactor startup, has signed a letter of intent with Poland’s Legnica Special Economic Zone (LSSE) and DB Energy for a power plant featuring 10 small modular reactors with 200 MWe of capacity to fuel the region’s industrial activities. (Established in 1997, the LSSE covers 18 subzones located in the central part of southwestern Poland’s Dolnośląskie Province and is home to more than 75 companies providing some 16,000 jobs.)
America’s nuclear navy presently has 86 nuclear-powered submarines and aircraft carriers. All of them, and their predecessors over the last 60 years, have performed flawlessly, protecting America as well as their crews. Here, the nuclear submarine USS Seawolf leads the nuclear-powered aircraft carrier USS Nimitz and the conventionally powered Japan Maritime Self-Defense Force destroyer JS Oonami DD 111 during exercises in 2009.

Just this last April, President Biden officially commissioned the USS Delaware, a new Virginia-class nuclear attack submarine, the 18th built in that class and the eighth and final Block III Virginia-class submarine. (The Delaware was administratively commissioned in April 2020, but the COVID-19 pandemic caused delay of the ceremony for two years.)

The Nuclear Regulatory Commission has directed its staff to issue a final rule certifying NuScale Power’s small modular reactor design for use in the United States, the agency announced last Friday.
Certification of the Portland, Ore.–based SMR developer’s design will become effective 30 days after publication of the rule in the Federal Register. The design will be incorporated as Appendix G to 10 CFR Part 52, Licenses, Certifications, and Approvals for Nuclear Power Plants.

The Government Accountability Office is recommending that Congress clarify the Department of Energy’s legal authority to sell depleted uranium hexafluoride (DUF6) left over from uranium enrichment operations at the department’s Portsmouth Site in Ohio and the Paducah Site in Kentucky.
An approach to future plant fabrication and siting suitable for many reactor types and scales, with large potential worldwide benefits
The offshore plant combines two mature technologies: the floating rig and the nuclear reactor.
In recent years, the rate of building new nuclear power plants has slowed internationally except in some rapidly developing countries. In Western countries that have considerable experience with nuclear power, completion of new projects on time and on budget has become more difficult. Shipyard-fabricated plants may offer a new direction for meeting international needs and responding to requirements for better cost control and safety. In this article we offer an overview of the floating nuclear power plant concept, including experience with it to date and its key engineering and strategic features, along with related uncertainties and needed conditions for future projects to be successful.

Savannah River Mission Completion (SRMC), the radioactive liquid waste contractor at the Department of Energy’s Savannah River Site, is optimizing some equipment maintenance at the Salt Waste Processing Facility (SWPF). The facility traditionally uses centrifugal contactors in the solvent extraction process, and its laboratory uses manipulators to handle process samples and equipment within its radioactive cell. The equipment requires periodic maintenance and rebuilding.

In a 243–187 vote, the House of Representatives yesterday passed the CHIPS and Science Act of 2022, a $280 billion economic competitiveness package aimed at bolstering U.S. semiconductor manufacturing, as well as scientific research and development, including nuclear energy R&D.

The DIII-D National Fusion Facility now boasts a unique automated system that allows for a quick reversal of the direction of its magnetic field, expanding the range of possible fusion experiments while reducing downtime. General Atomics, which operates the DIII-D for the Department of Energy’s Office of Science, announced the new Toroidal Field Reversing Switch (TFRS) on July 26.
