EXECUTIVE SUMMARY Based on the site visit and walkdowns, the Pantex Plutonium Environment Safety & Health (ES&H) Vulnerability Assessment Working Group Assessment Team (WGAT) considers the Site Assessment Team (SAT) report and question sets to be a factual assessment of the facilities, except where specifically noted in this report. As a result of the SAT and WGAT' s reviews, 6 ES&H vulnerabilities, (4 by the SAT and 2 by the WGAT) were identified for further consideration by the Department of Energy (DOE) Plutonium ES&H Vulnerability Working Group preparing the final report. All 6 vulnerabilities were discussed with the respective site team members and facility experts and agreement was reached. The vulnerabilities identified by the SAT and WGAT are described below. No ranking or priority is implied by the order in which they are listed. In addition the WGAT identified and included issues for consideration by the Pantex Plant and DOE management that are not explicit ES&H vulnerabilities. Vulnerabilities identified by the WGAT and SAT are described below and are included as Appendix A Vulnerability Assessment Forms (VAFs). They are presented by review topic and facility, and do not represent a prioritization of the identified vulnerabilities. General Plutonium Pit Handling and Storage A cross-cutting review of general plutonium pit handling and storage was conducted. The WGAT concurs with the two vulnerabilities identified by the SAT on an operational accident causing pit cladding or pit tube failure and the need to improve expertise on pit aging and design. The WGAT has developed a supplemental vulnerability on pit aging concern. Further, a second vulnerability was developed by the WGAT with respect to pits which have been subjected to special testing. These vulnerabilities apply to all facilities where plutonium pits are handled and/or stored. These vulnerabilities are considered low probability events and the potential consequences are moderate with respect to the worker and negligible for the public. As a result of the operational accident, environmental consequences would be limitedto Zone 4 where localized contamination of the magazine and nearby soil could occur. 12-26 Bay 27 The SAT review identified potential roof collapse due to natural phenomena as a vulnerability in Building 12-26 Bay 27. The WGAT concurs with the SAT assessment. This vulnerability has a low potential for causing an ES&H event, with the potential for worker injury, contamination, exposure, and a localized release to the environment, but no impact on the public. 12-26 Vault The WGAT concurs with the SAT assessment that there are no vulnerabilities specific to Building 12-26 Vault.
