stockpile stewardship

Ensuring the safety, security and reliability of the nuclear deterrent

LLNL's Weapons and Complex Integration (WCI) Directorate works to ensure the remaining deterrent remains safe, secure and reliable. WCI accomplishes this through the Stockpile Stewardship Program — an ongoing effort to apply a science-based fundamental understanding of nuclear weapons performance — from the development of enhanced warhead surveillance tools that detect the onset of problems to manufacturing capabilities that produce critical components.

Using the Laboratory's tools and talents, the nation has been able to assess and certify the safety, security and reliability of the stockpile each year without a return to nuclear testing for more than 20 years.

WCI scientists and engineers are able to accomplish this through unique centers of excellence, including:

Through these cutting-edge tools, coupled with the Lab's multidisciplinary expertise, the nation can successfully transition to a reduced stockpile.
