It may take almost a year longer than recently expected to fully certify the F-35A to internally carry one or two B61-12 nuclear gravity bombs, but the head of the service’s Nuclear Weapons Center said the nuclear end of things isn’t what’s pacing the process. “The timing right now I think to get to full […]

The federal government’s independent nuclear health and safety watchdog wants to know what the National Nuclear Security Administration is doing to address perceived safety culture issues at the country’s central nuclear-weapons maintenance facility.

As far as the Department of Energy could tell at deadline, the hack of a small, veteran-owned consulting business in Albuquerque, N.M., did not compromise any National Nuclear Security Administration data. “The Department of Energy is aware of the cyberattack against Sol Oriens, a veteran-owned consulting firm whose clients include the Department of Energy/National Nuclear […]

The Lawrence Livermore National Laboratory published new research about how near-surface detonations can affect nuclear-weapon yields, the California-based design lab said Monday. The findings, summarized in a paper titled “the reflection of a blast wave by a very intense explosion,” were published last week in Proceedings A of the Royal Society Publishing. The authors are […]

“The bow wave has arrived” for the civilian nuclear-weapons budget, the Government Accountability Office warned Wednesday in a report that, amid recommendations for streamlining budget and project organization, made room for a we-told-you-so about the effects of deferring upgrades for nuclear weapons and their production infrastructure. “DOE’s appropriation for fiscal year 2021 includes a 23 […]

It will take about a month longer than previously thought for personnel at the Los Alamos National Laboratory to certify that a key component of the site’s planned plutonium pit factory can safely accept the higher volumes fissile material required to support the pit mission. The Radiological Laboratory/Utility/Office Building (RLUOB) will be recategorized as a […]

The National Nuclear Security Administration cannot meet a legal requirement to make at least 80 new plutonium cores for intercontinental ballistic missile warheads in 2030, the agency’s acting boss told lawmakers Thursday. With the planned Savannah River Plutonium Processing Facility (SPPPF) up to five years behind scheduled, “based on our latest information we assess that […]

A proposed testing program for an experimental, 20-kilowatt nuclear reactor — and its eventual dismantling and defueling after a planned two-year run — won’t harm the environment, the Department of Energy reiterated this week in a final environmental review for the project. In a proposed finding of no significant impact notice published Tuesday on its […]

The head of the Defense Nuclear Facilities Safety Board told federal contractors Thursday her agency could approve a memorandum of understanding on its “rules of the road” with the Department of Energy as early as next month. “We did have a great conversation with Deputy Secretary [David] Turk earlier this year and “it looks like […]
