Most weapons in the U.S. nuclear stockpile were produced over 20 years ago and are being sustained beyond original design lifetimes. It is critical to ensure that these weapons are safe, secure, and reliable to perform as the nations nuclear deterrent. The National Nuclear Security Administration (NNSA), a semiautonomous agency within the Department of Energy, is responsible for the nations nuclear weapons program. NNSA identifies nuclear weapon limitations—areas where military requirements may not be met—and conducts nonnuclear tests to evaluate the condition and reliability of weapons through its nuclear stockpile surveillance program. GAO was asked to determine the (1) number and types of such limitations and any concerns raised by Department of Defense (DOD) officials, and (2) actions NNSA has taken to implement its prior recommendations for the nuclear stockpile surveillance program. GAO reviewed agency documents, analyzed limitations, and interviewed key NNSA and DOD officials.In a February 2012 report, for the 52 NNSA identified limitations for all weapons in the U.S. nuclear stockpile, 86 percent fall into six types: detonation safety under abnormal conditions, weapon reliability, weapon delivery, more frequent replacement of limited life components, nuclear yield, and worker safety. Some DOD officials expressed concern over the impact that certain weapon limitations have on weapon operation, maintenance, and war planning. According to DOD officials, current DOD mitigation actions, as well as the successful completion of ongoing and planned NNSA efforts, should address most limitations for which the officials raised concerns. DOD officials stated that the current stockpile allows sufficient flexibility to mitigate limitations. However, they told GAO that there may be less flexibility in the future as the stockpile continues to age and decreases in size.In separate testimony, a GAO official addresses (1) NNSAs ability to produce budget and cost data necessary to make informed management decisions, (2) improving NNSAs project and contract management, and (3) DOEs and NNSAs safety and security oversight.This is a privately authored news service and educational publication of Progressive Management.
