The bill requires the head of the nuclear security program to quickly develop and begin executing a detailed plan to modernize the nuclear security enterprise’s material‑staging facilities and related high‑explosives infrastructure. It sets tight deadlines—90 days to draft the plan and 180 days to brief key congressional committees—aimed at replacing outdated, over‑used facilities and accelerating critical decisions for fiscal year 2026. The plan and briefings involve the Senate and House Armed Services and Appropriations committees.

Key Provisions

Within 90 days of the law taking effect, the Administrator for Nuclear Security must create a plan to upgrade and replace aging material‑staging facilities, outlining each phase and estimating the costs.
The plan must also speed up key decision milestones for fiscal year 2026.
The Administrator must carry out this plan at the same time as an infrastructure modernization program for high‑explosives capabilities, including continuing construction of the High Explosives Synthesis Formulation and Production facility (21‑D‑510).
Within 180 days, the Administrator must brief the Senate and House Armed Services and Appropriations committees on the material‑staging plan.
