CHAPTER III

           TWO-PERSON CONCEPT FOR NUCLEAR EXPLOSIVE OPERATIONS


1.  GENERAL.  This Chapter prescribes requirements to establish the
    two-person concept for operations with nuclear explosives.  The
    two-person concept is one of the procedures implemented to enhance
    nuclear explosive safety and to prevent an accidental or an unauthorized
    action with a nuclear explosive.

2.  TWO-PERSON CONCEPT.  The two-person concept for operations requires that
    a minimum of two authorized persons in the DOE Personnel Assurance
    Program, each having technical knowledge and being in a position to
    detect incorrect or unauthorized operations with respect to the task to
    be performed and familiar with pertinent safety and security
    requirements, be present during all operations that afford access to a
    nuclear explosive.  The two-person concept applies to any area that
    contains a nuclear explosive or principal components of a nuclear
    explosive (main charges/pit) or any other designated area from which a
    lone individual is denied access.

3.  IMPLEMENTATION.  Managers of the Operations Offices responsible for
    operations with nuclear explosives shall establish procedures for
    implementing the two-person concept.
