DOE wants hydrogen-based “energy parks” at light water reactor sites

September 9, 2022, 12:07PMNuclear News

The Department of Energy is offering cost-shared funding that could lead to the demonstration of an “energy park” drawing 20–300 MW of thermal energy from a U.S. nuclear power plant under a funding opportunity amendment issued in August by the DOE’s Office of Nuclear Energy Light Water Reactor Sustainability (LWRS) program, in coordination with the DOE’s Office of Energy Efficiency and Renewable Energy Hydrogen and Fuel Cell Technologies Office.

The Level 1 probabilistic risk assessment standard for nuclear power plant applications

The American Society of Mechanical Engineers/American Nuclear Society Joint Committee on Nuclear Risk Management (JCNRM) has issued a new edition of its flagship standard, ANSI/ASME/ANS RA-­S-­1.1-­2022, Standard for Level 1/Large Early Release Frequency Probabilistic Risk Assessment for Nuclear Power Plant Applications. This standard was approved by the JCNRM, the ANS Standards Board, and the ASME Board on Nuclear Codes and Standards before being approved on May 11 by the American National Standards Institute (ANSI), earning the title of an American National Standard. With most of the text stable for the past year, the production process was started early, allowing the 400-­page standard to be published on May 31, 2022.

The big nuclear world

As I write this column, it’s late September, and I’m sitting in Dulles Airport waiting for my connecting flight back to Charlotte from Vienna, Austria, where I attended the 65th General Conference of the International Atomic Energy Agency. It was quite an experience, and I want to share a few observations with you. But first, let me provide some background on the IAEA, which is perhaps not as well-­known to Americans as to those in other countries.

The IAEA was established in 1957 within the United Nations family and as an outgrowth of President Dwight Eisenhower’s famous 1953 “Atoms for Peace” speech. It is the world’s central intergovernmental forum for scientific and technical cooperation in the nuclear field. The objectives of the IAEA’s dual mission—to promote and control the use of the atom—are defined in Article II of the IAEA Statute.

UAMPS downsizes NuScale SMR plans

When Utah Associated Municipal Power Systems (UAMPS) in 2015 announced its plan to develop the Carbon Free Power Project (CFPP) using NuScale Power’s modular light water reactor design, it envisioned the construction of a dozen 50-MWe modules for a plant that could produce a total of 600 MWe. The CFPP’s target output later rose to 720 MWe, when UAMPS opted to scale up to 60-MWe modules. In late June, the plans changed once again, as UAMPS participants chose to build 77-MWe modules but downsize the plant from 12 units to six, which would yield 462 MWe—about 64 percent of the 720 MWe that could have been generated from 12 of the 60-MWe modules.

“Now is the time” for more ATR capacity: A conversation with Lightbridge

Operators at the Advanced Test Reactor at Idaho National Laboratory have begun a nine-month outage to perform a core internals changeout. When the ATR is restarted in early 2022, the top head closure plate of the pressurized water test reactor will have new access points that could permit the irradiation of more fuel and material samples in the reactor’s high-flux neutron conditions.

ANS standards updates

May 12, 2020, 1:29PMNuclear News

ANS publishes standards that set forth requirements for the design, manufacture, or operation of a piece of equipment. These standards can address computer firmware and software, and can address the necessary physical and functional features of equipment, its safe application, or some combination of these. These standards are applied on a voluntary basis, and when adopted by a state or federal agency, they becomes part of their mandatory codes.

ANS standards are available at the ANS Standards store.

The following standards have been approved, published, or are open for comment.
