Atomic Energy Defense Activity

Any activity of the Secretary performed in whole or in part in carrying out any of the following functions:

(1) Naval reactors development;
(2) Weapons activities, including defense inertial confinement fusion;
(3) Verification and control technology;
(4) Defense nuclear materials production;
(5) Defense nuclear waste and materials by-products management;
(6) Defense nuclear materials security and safeguards and security investigations; and
(7) Defense research and development.

(This term is broader than “DOE defense nuclear facilities” since the latter excludes specific “atomic energy defense activities,” for example, those related to naval reactors.)
