The Department of Energy's (Department) National Nuclear Security Administration's (NNSA)
research, surveillance, and manufacturing capabilities are carried out in facilities, many of which
are 50 to 60 years old. Since these facilities are beyond their economic lifetime, NNSA
requested and acquired funding not only to construct new facilities but also to restore and
revitalize older ones. These construction projects enable NNSA to maintain the critical
capabilities necessary to support its programmatic efforts such as nuclear nonproliferation,
counterterrorism, and emergency response work.
