§6131 Stockpile responsiveness program

Summary

The United States must keep and practice all the skills, tools, and facilities needed to design, build, test (without a nuclear explosion), certify, produce, and deploy nuclear weapons so the country’s deterrent stays safe, secure, reliable, credible, and ready. The Secretary of Energy, working through the Administrator and consulting the Secretary of Defense, must run a stockpile responsiveness program alongside other stockpile programs to do this work. The program must keep and improve capabilities across science, engineering, design, certification, and manufacturing for every phase of the joint nuclear weapons life cycle. It must pass knowledge to the next generation of designers and engineers, show responsiveness using prototypes, flight tests, and integrated demos, develop faster and cheaper technologies for life‑extension or new weapon projects, exercise coordination with the Defense Department, and, with the Director of National Intelligence, keep the ability to assess and build foreign prototype weapons and do no‑yield tests if needed. The joint nuclear weapons life cycle process is the shared Defense and Energy process for developing, making, keeping, and retiring nuclear weapons.

(a)It is the policy of the United States to identify, sustain, enhance, integrate, and continually exercise all capabilities required to conceptualize, study, design, develop, engineer, certify, produce, and deploy nuclear weapons to ensure the nuclear deterrent of the United States remains safe, secure, reliable, credible, and responsive.
(b)The Secretary of Energy, acting through the Administrator and in consultation with the Secretary of Defense, shall carry out a stockpile responsiveness program, along with the stockpile stewardship program under section 6111 and the stockpile management program under section 6116, to identify, sustain, enhance, integrate, and continually exercise all capabilities required to conceptualize, study, design, develop, engineer, certify, produce, and deploy nuclear weapons.
(c)The program under subsection (b) shall have the following objectives:
(1)Identify, sustain, enhance, integrate, and continually exercise all of the capabilities, infrastructure, tools, and technologies across the science, engineering, design, certification, and manufacturing cycle required to carry out all phases of the joint nuclear weapons life cycle process, with respect to both the nuclear security enterprise and relevant elements of the Department of Defense.
(2)Identify, enhance, and transfer knowledge, skills, and direct experience with respect to all phases of the joint nuclear weapons life cycle process from one generation of nuclear weapon designers and engineers to the following generation.
(3)Continually demonstrate stockpile responsiveness throughout the range of capabilities as required, such as through the use of prototypes, flight testing, integrated system demonstrations, and development of plans for certification without the need for nuclear explosive testing.
(4)Develop technologies for transition to a nuclear stockpile life extension program or new nuclear weapon program project that have the potential to reduce design, certification, and manufacturing cycles cost and schedule.
(5)Continually exercise processes for the integration and coordination of all relevant elements and processes of the Administration and the Department of Defense required to ensure stockpile responsiveness.
(6)The retention of the ability, in coordination with the Director of National Intelligence, to assess and develop prototype nuclear weapons of foreign countries if needed to meet intelligence requirements and, if necessary, to conduct no-yield testing of those prototypes.
(d)In this section, the term “joint nuclear weapons life cycle process” means the process developed and maintained by the Secretary of Defense and the Secretary of Energy for the development, production, maintenance, and retirement of nuclear weapons.
