Released midday Tuesday, the Senate Armed Service’s version of the 2024 defense policy bill boosts spending on nuclear weapons by $276 million and increases overall funding for the National Nuclear Security Administration, compared with the agency’s funding request.  Senate Armed Services Committee Chairman Sen. Jack Reed (D-R.I.) and Ranking Member Sen. Roger Wicker (R-Miss.) jointly […]

Lawrence Livermore National Laboratory and Sandia National Laboratories have successfully performed a second joint abnormal thermal environment test for the W80-4 Life Extension Program, the labs recently announced.  Carried out April 5 at Sandia’s Cross Wind Test Facility in New Mexico, this abnormal thermal environment test, or ATE-2, was a fast-heat, fully engulfing system-level fuel […]

Department of Energy Secretary Jennifer Granholm and National Nuclear Security Administration head Jill Hruby are too legit to quit. In mid-May, the pair hosted former rapper and “science enthusiast” MC Hammer at the National Ignition Facility (NIF) in Livermore California.  Hruby included a photo of the three of them, along with Kim Budil, director of […]

Lawrence Livermore National Laboratory added SambaNova Systems’ spatial data flow accelerator to the lab’s Livermore Computing Center as part of an effort to see if artificial intelligence can aid the nuclear-weapons program. Livermore will integrate the new hardware to further investigate cognitive simulation approaches combining artificial intelligence (AI) with high-performance computing to learn if deep […]

Problems with components are mostly responsible for the two-year delay to the warhead for the next nuclear-tipped air-launched cruise missile, the head of the National Nuclear Security Administration told lawmakers Wednesday. There are “few components that are pacing the schedule” for the W80-4, Jill Hruby, administrator of the National Nuclear Security Administration (NNSA) told the […]

NATO and the U.S. State Department this week held the 18th Annual NATO Conference on Arms Control, Disarmament and Weapons of Mass Destruction (WMD) Non-Proliferation in Washington, D.C. NATO Secretary General Jens Stoltenberg and U.S. Deputy Secretary of State Wendy Sherman delivered remarks at the opening session of the conference on April 18. “NATO will […]

The Air Force and Navy on Wednesday morning used an airborne control center to test-fire an unarmed Minuteman III missile, the services said. The test gave the services a look at the Airborne Launch Control System (ALCS), an aircraft that can launch intercontinental ballistic missiles if ground-based communication with nuclear silos is disabled.  A joint […]

The Department of Energy could spend $20 million on tearing down contaminated old facilities at the Lawrence Livermore National Laboratory in California during fiscal 2024, or about $15 million less than what Congress approved for that purpose in fiscal 2023, according to the White House budget justification out last week. The DOE Office of Environmental […]

The National Nuclear Security Administration’s budget request for fiscal year 2024 includes a funding boost for plutonium pit production in New Mexico, with the goal of building 80 per year as close to 2030 as possible.  Also in the request, the NNSA provided a new cost and schedule estimate for completing the Uranium Processing Facility […]

The U.S. military lags behind both Russia and China in building and fielding low-yield nuclear weapons and can address that gap by diversifying the military’s nuclear options, the head of U.S. Strategic Command told Congress on Thursday. Air Force Gen. Anthony Cotton, in charge of U.S. nuclear forces since December, said he launched a review […]

Below is Nuclear Security & Deterrence Monitor’s annual digest of the National Nuclear Security Administration’s (NNSA) performance evaluation summaries: the agency’s report cards for its big contracts, which explain how much management and operations entities earned for their performance. The Monitor has provided links to NNSA source documents. Kansas City National Security Campus, Kansas City, […]

The Department of Energy prime for Lawrence Livermore National Laboratory in California is looking for contractors interested in performing building demolition. Bechtel-led Lawrence Livermore National Security, the contractor managing the laboratory for DOE’s semi-autonomous National Nuclear Security Administration (NNSA) posted a sources-sought notice Thursday March 2 seeking a subcontractor for building and slab demolition as […]

The technology that powers the Lawrence Livermore National Laboratory’s main nuclear-weapon testing center is a viable bedrock for a nuclear fusion power plant, the lab’s director testified Tuesday in Congress. Based on data available today from Livermore’s National Ignition Facility (NIF), “it is feasible to develop a fusion energy power plant based on the inertial […]

Kim Budil, director of the Lawrence Livermore National Laboratory, was set to testify Tuesday in Washington during a hearing of the House Science, Space and Technology Committee. The hearing, “The United States, China and the Fight for Global Leadership: Building a U.S. National Science and Technology Strategy,” was on the slate for 10:00 a.m. Eastern […]

ARLINGTON, VA. — The Lawrence Livermore National Laboratory will serve as a test-bed for some of the changes the National Nuclear Security Administration plans to make to the big site-management contracts of the future, an agency official said here. At “the Livermore Field Office … we are actually right now executing what’s called a model […]

ALEXANDRIA, VA — The Lawrence Livermore National Laboratory was set to fire the first test in its Nimble series of subcritical experiments in the late summer, a senior lab official said here Wednesday. “The first one [called Nob Hill] is scheduled for August of this year, the next one [Twin Peaks] will be hopefully a […]

ARLINGTON, VA. — The National Nuclear Security Administration changed the design for the nuclear core of a planned intercontinental ballistic missile warhead late last year, a senior agency official said here Tuesday.
