CHAPTER VI

                  PERMANENT MARKING INSTRUCTIONS AND
             NUCLEAR EXPLOSIVE-LIKE ASSEMBLY REQUIREMENTS


1.  GENERAL.  This Chapter addresses the requirement for having permanent
    marking instructions for nuclear explosives and nonnuclear
    configurations, and having nuclear explosive-like assembly (NELA)
    requirements for the assembly and identification of nonnuclear
    configurations.

2.  APPLICABILITY.  Permanent marking instructions apply to nuclear
    explosives and to nonnuclear configurations that are in the custody of
    the DOE.  NELA requirements apply to the assembly and identification of
    nonnuclear configurations that are in the custody of the DOE.

3.  PERMANENT MARKING INSTRUCTIONS.  Technical criteria for permanent
    marking instructions shall be established by the Manager, Albuquerque
    Operations Office.  Permanent marking of nuclear explosives and
    nonnuclear configurations provide a rapid and accurate method to
    distinguish between configurations capable of nuclear detonation and
    those incapable of nuclear detonation.

4.  NELA REQUIREMENTS.  Technical criteria for NELA requirements shall be
    established by the Manager, Albuquerque Operations Office.  These
    requirements will provide positive measures to prevent the accidental,
    inadvertent, or deliberate unauthorized assembly of a nuclear explosive
    in place of a nonnuclear configuration, and the accidental, inadvertent,
    or deliberate unauthorized transfer of a nuclear explosive in place of a
    nonnuclear configuration.

5.  IMPLEMENTATION.  Managers of other operations offices shall implement
    the criteria for permanent marking instructions and NELA requirements
    as established by the Manager, Albuquerque Operations Office, as
    applicable.
