SUBJECT:     DOE O 452.2D Nuclear Explosive Safety;
                     DOE O 452.6A Nuclear Weapon Surety Interface with DOD;
                     DOE M 452.2-1A Nuclear Explosive Safety Manual;

SUMMARY:   The Department issued a Contractor Requirements Documents (CRDs) on April
                     14, 2009 to the above listed Directives.

                     Under the Department's Directives Program (DOE Order 251.1B), Heads of Field Elements are
                     responsible for determining which contracts are to include the CRDs. Contracting Officers, once
                     notified, are responsible for incorporating the CRDs into affected contracts. Since some Heads
                     of Field Elements may not be aware that this change has been issued, Contracting Officers
                     should request their determination of which, if any, contracts are affected and remind them that
                     they may sign up for automated notification at www.directives.doe.gov.

                     Questions regarding contracts intended to be affected by the CRDs should be directed to the
                     office identified in the "Contact" paragraph and questions regarding contract modifications
                     should be directed to Helen Oxberger at helen.oxberger@hq.doe.gov.
