CHAPTER VIII

          ONSITE AND OFFSITE TRANSPORTATION OF NUCLEAR EXPLOSIVES


1.  GENERAL.  This Chapter establishes the requirements for assuring the
    nuclear explosive safety of the onsite and offsite transportation of
    nuclear explosives in the custody of the DOE.  The process specified in
    Chapter V for evaluation by the Nuclear Explosive Safety Study Group
    (NESSG), for preparation of a NESSG report, and for approval of the
    NESSG report by DP-20, is applicable to all onsite and offsite
    transportation of nuclear explosives.

2.  REQUIREMENTS.

    a.  Prior to the onsite transportation of nuclear explosives, the
        following requirements shall be met:

        (1)  Vehicles for transportation shall be studied by the NESSG and
             approved.

        (2)  Loading, unloading, and tie-down equipment and procedures
             shall be studied by the NESSG and approved.

    b.  Prior to the offsite transportation of nuclear explosives, the
        following requirements shall be met:

        (1)  Nuclear explosives shall be transported in a safe-secure
             trailer (SST) or safe-secure rail car (SSR) and the
             transportation shall be in accordance with the procedures
             specified in Technical Publication (TP) 45-51D (SST) or TP
             45-51E (SSR).

        (2)  Transportation of nuclear explosives shall comply with the
             general instructions specified in TP 35-51; the transportation
             procedures, equipment, and tie-down requirements specified in
             TP 45-51; and the technical data specified in TP 45-51A.

        (3)  Transportation of nuclear explosives shall comply with the
             plutonium limits specified in TP 20-7.

        (4)  A safety analysis report (SAR) shall be prepared for the SST
             or SSR.

        (5)  Written operating procedures shall be prepared and approved.

        (6)  A risk assessment report shall be prepared and shall consider
             the requirements in paragraphs 2b(1) through 2b(5) above.
             The nuclear explosives shall be assessed within the SST or
             SSR, to include the protection provided by the SST or SSR.

    c.  Prior to the offsite transportation of an unassembled nuclear
        explosive, which includes the main charge high explosive parts and
        pit, for a specific test device, the following requirements shall
        be met:

        (1)  The unassembled nuclear explosive shall be transported in a
             SST.

        (2)  Loading, unloading, and tie-down equipment and procedures
             shall be studied and approved.

        (3)  Transportation of the unassembled nuclear explosive shall
             comply with the plutonium limits specified in TP 20-7.

        (4)  A safety analysis report (SAR) shall be prepared for the SST.

        (5)  Written operating procedures shall be prepared and approved.

        (6)  A risk assessment report shall be prepared and shall consider
             the requirements in paragraphs 2c(1) through 2c(5) above.
             The unassembled nuclear explosive shall be assessed within
             the SST, to include the protection provided by the SST.
