CHAPTER X

        REQUIREMENTS FOR NUCLEAR EXPLOSIVE OCCURRENCE REPORTING


1.  GENERAL.  This Chapter establishes requirements whereby reportable
    occurrences during nuclear explosive operations are reported and
    analyzed and follow-up action is taken.  The objectives of these
    requirements are to ensure prompt notification and appropriate action
    by DOE officials; that reportable occurrences are analyzed for the
    purpose of taking corrective actions to prevent the repetition of
    similar events which could degrade nuclear explosive safety; to
    identify any trends in occurrences, and to assure standardization of
    reporting.  Information on these occurrences shall be analyzed,
    evaluated, and disseminated to all organizations who have been or could
    be effected.

2.  CATEGORIZATION.  Categorization of reportable occurrences shall be made
    as soon as practical and in all cases within 2 hours of identification.
    If categorization is not clear within the 2-hour timeframe, then the
    occurrence shall be initially categorized at the higher level being
    considered and DOE notified in accordance with this Order.  Occurrences
    categorized as emergencies shall be reported immediately, i.e., in
    accordance with 3a of this Chapter.  The occurrence categorization
    shall either be evaluated, maintained, or lowered as information is
    made available.  The categories of reportable occurrences are:

    a.  Emergency.  Emergencies are the most serious occurrences and
        require an increased alert status for onsite personnel and in
        specified cases for offsite authorities.  The detailed
        classification for emergencies and the emergency responses to be
        taken are provided in DOE 5500.2A.  The types of nuclear explosive
        occurrences that are to be categorized as emergencies are:

        (1)  Nuclear or high-explosive detonation.

        (2)  Dispersal of plutonium from a nuclear explosive.

        (3)  Seizure, theft, or loss of a nuclear explosive.

        (4)  Inadvertent or deliberate unauthorized arming of a nuclear
             explosive.

        (5)  Any safeguards or security event involving nuclear explosives
             that is an actual or potential threat to DOE operations,
             facilities, or personnel, and results or could result in
             significant effects on the public health and safety and/or on
             the national security.

    b.  Unusual Occurrence.  An unusual occurrence is a significant
        unplanned occurrence involving a nuclear explosive that results
        in the following:

        (1)  The unauthorized introduction of electrical energy into a
             nuclear explosive.

        (2)  The unauthorized compromise of a nuclear explosive safety
             feature when installed on a nuclear explosive.

        (3)  A violation of a nuclear explosive safety standard or a
             nuclear explosive safety rule.

        (4)  A violation of the two-person concept.

        (5)  A "near miss" or damage to a nuclear explosive that could
             result in a credible threat to nuclear explosive safety.

        (6)  The damage to a nuclear explosive that results from an onsite
             or offsite transportation accident.

    c.  Off-Normal Occurrence.  An off-normal occurrence is an abnormal or
        unplanned event or condition that adversely affects the nuclear
        explosive safety program, but are not in the emergency or unusual
        occurrence category, such as:

        (1)  Temporary removal of an individual from nuclear explosive
             duty.

        (2)  Revocation of the PAP certification of an individual.

        (3)  The identification of failure to comply with PAP requirements
             or procedures.

        (4)  The identification of improperly maintained records required
             in the nuclear explosive safety program.

3.  NOTIFICATION.  Requirements for verbal and written notification of
    reportable occurrences are as follows:

    a.  Emergencies.  Verbal notification to DOE of emergencies shall be
        made within 15 minutes or less of categorization.  Written
        notification shall be made as soon as practical, but in any event,
        within 24 hours of categorization, utilizing the notification
        Report (first page of the Occurrence Report).

    b.  Unusual Occurrences.  Verbal notification to DOE of unusual
        occurrences shall be as soon as sufficient information is obtained
        to indicate the general nature and extent of the occurrence, but
        in any event, within 2 hours of categorization.  Written
        notification shall be made within 24 hours of categorization
        utilizing the Notification Report.

    c.  Off-Normal Occurrences.  For off-normal occurrences verbal
        notification to DOE is not mandatory, but written notification
        shall be made within 24 hours of categorization utilizing the
        Notification Report.

    Note:  DP-20 shall receive initial and follow-up reports to closure
    relating to all categories of this Order, in addition to any other
    Departmental requirements.

4.  FOLLOW-UP NOTIFICATION.  In addition to the initial verbal notifications
    required above, follow-up verbal notification shall also be made to DOE
    for any of the following:

    a.  Any degradation in the level of safety or other worsening
        conditions, including those that require the declaration of any of
        the emergency action levels, if such a declaration has not been
        previously made.

    b.  Any change from one emergency level to another.

    c.  Termination of an emergency.

5.  OCCURRENCE REPORT PREPARATION.  All occurrence report preparation will
    be performed as specified in DOE 5000.3A.
