In early February 2022, Laboratory personnel successfully completed the Qualification Design Review (QDR) for the B61-12 Life Extension Program (LEP). QDR is also known as the Delta FDRAAG, short for Delta Final Design Review and Acceptance Group.
When the Laboratory’s Detonator Production team originally completed manufacturing two ALT939 DEV#1 functional cables — the first development units produced in this lot, team members quickly hit an obstacle when electrical testing for these cables failed. Team members sent the cables out for further testing, which revealed the root cause of failure involved the cables’ connectors. Although a challenging issue to resolve, the team worked together and solved the issue ahead of a stipulated deadline, with the cables completed and shipped to support system tests. The team responsible for this challenging work included members from Detonator Production, Nondestructive Testing & Evaluation, and collaborators from Sandia National Laboratories.
An efficient Picard-based solver is proposed for a novel energy conserving particle integrator preserving all first-order guiding center drifts and correct gyroradius for large time steps in arbitrary (non-uniform) magnetic fields. This research enables the efficient deployment of the novel asymptotic preserving (AP) particle orbit integrator into modern energy-conserving, implicit particle-in-cell codes, delivering a truly multiscale simulation capability.

Associate Laboratory Director for Plutonium Infrastructure Mark Anthony and a procurement team visited three glovebox fabricators the week of Aug. 23, 2022, to discuss equipment procurement options and assess the vendors’ production capability, factory conditions, and safety records. The team determined that all three fabricators can produce complex gloveboxes and meet Nuclear Quality Assurance-1 standards.
On Sept. 26, Director Thom Mason signed the Laboratory’s annual assessment of four of the weapons systems in our nation’s nuclear stockpile: the B61 family of bombs and the W76, the W78 and the W88 warheads. Addressed to the secretary of energy, the secretary of defense and the chair of the Nuclear Weapons Council, this letter informs the president of the United States of our confidence that the stockpile remains safe, secure, and effective now and into the future as a result of our dedicated sustainment and modernization efforts.
On November 16, Los Alamos National Laboratory Director Thom Mason answered questions from the Defense Nuclear Facilities Safety Board (DNFSB) at a public hearing in Santa Fe about the safety of operations at the Laboratory’s plutonium facility and the pit production mission. Mason participated on a panel along with National Nuclear Security Administration’s (NNSA) Administrator Jill Hruby, Deputy NNSA Administrator James McConnell, and NNSA Los Alamos Field Office Manager Ted Wyka.
