changes in the CONOPS or STS; additional new equipment and or weapons; proposed changes
to nuclear weapon system safety rules; or storage of inactive nuclear weapons.
(a) An SSS will be conducted for a nuclear weapon system when deemed necessary
by the Military Department concerned or when requested by the ASD(NCB). DOE and DTRA
may request, through the ASD(NCB), that an SSS be conducted. An SSS may be conducted
with an OSR, if desired.
(b) The NWSSG will:
1. Examine modifications, alterations, retrofits, and special tests.
2. Assess potentially unsafe conditions revealed by operational experience,
studies, or analyses.
3. Review significant changes in the system CONOPS, operational conditions,
STS, or performance of the safety features incorporated into the weapon system.
4. Review ULA and ILA, if applicable.
5. Review probabilistic risk assessment (PRA) reports, when available, to help
evaluate the nuclear weapon system's compliance with the first and third DoD nuclear weapon
system surety standards.
6. Recommend changes or additions to safety rules, as applicable.
(c) Military Department SSS NWSSG reports will be made available by the
responsible Military Department to the nuclear weapon system LPO (or program manager, as
applicable) for information.

7. STUDY AND REVIEW PROCEDURES
a. Pre-study and Review Requirements
(1) The Military Department will request and consider recommendations from the
NWSSG member organizations regarding the scope and agenda of the study or review, and will
distribute a convening letter and an agenda to member organizations.
(2) A Military Department data package will be provided to NWSSG member
organizations at least 30 days before the start of a study or review. The package will include at a
minimum:
(a) Technical description and CONOPS for the nuclear weapon system. That
information subsequently becomes Part A of the Military Department safety rules package.
(b) Description of the safety features incorporated into the nuclear weapon system.
That information subsequently becomes Part B of the Military Department safety rules package.
(c) Current or draft safety rules, or draft changes to current safety rules, as proposed
by the Military Department. That information is Part C of the Military Department safety rules
package.
(3) The Military Department, in coordination with the Deputy Assistant Secretary of
Defense for Nuclear Matters (DASD(NM)) under the authority, direction, and control of the
ASD(NCB), will request that DOE provide the following information at the study site:
(a) Warhead descriptions, including history of alterations and modifications, status of
the major assembly release (MAR), and operating modes.
(b) A summary of the warhead design safety features, including use control, that
support the weapon safety theme.
(c) An assessment of how the design safety features support the MCs and the DoD
nuclear weapons system surety standards, including information on environments in which
inherent weapon design characteristics alone are inadequate to meet the MCs.
(d) Information concerning specific system security vulnerabilities that may be
accessed by the NWSSG Chair and limited to others in the group with a need to know, as
approved by the Military Department component in consultation with DASD(NM). Issues that
arise concerning such vulnerabilities will be addressed in the context of the impact to weapon
safety. Specific findings during limited access discussions will not be included in open findings
due to classification concerns.
(4) The Military Department will review the following material and make it available to
the NWSSG at the study site, as applicable:
(a) JNWPS TP and Military Department technical manuals.
28 APPENDIX 1 TO ENCLOSURE 3
DoDM 3150.02, January 31, 2014
(b) Pertinent material from previous Military Department NWSSG reports on the
specific nuclear weapon system, including approved findings and recommendations and
corrective action taken.
(c) The most recent POG and DRAAG reports.
(d) A summary of relevant accidents and incidents, NWTI results, and unsatisfactory
reports.
(e) Technical nuclear safety analyses, as available, that address system features,
interfaces, operations (e.g., transportation), and applicable risk assessments.
(f) Applicable operations orders, operations plans, directives, and related materials.
b. Conduct of the Study or Review. The NWSSG will conduct a safety study or review, in
accordance with this manual and the Military Department implementing instructions. The
NWSSG will:
(1) Review the Military Department data package.
(2) Review the status of relevant findings, recommendations, and open corrective actions
from previous Military Department NWSSG reports.
(3) Receive technical and operational briefings on the weapon system under study.
(4) Determine if the nuclear weapon system may be operated safely in the CONOPS.
Observe operations with applicable support equipment in a representative sample of operational
environments and in substantially unique operational environments, as applicable.
(5) Review technical and operational procedures in TPs and in safety rules, in view of
observed operations.
(6) Examine the STS document, with particular emphasis on storage, maintenance,
transportation, and employment operations, to ensure that all relevant activities that have safety
aspects are reviewed.
(7) Review potential hazards in normal and abnormal environments identified in the STS
document for impact on safety. Review possible credible abnormal environments and examine
potential hazards where applicable. [ Pobierz całość w formacie PDF ]
