Argonne National Laboratory-West EXECUTIVE SUMMARY Based on the site visit and walkdowns, the Working Group Assessment Team (WGAT) considers the Site Assessment Team (SAT) report and question sets to be a factual assessment of the facilities. As a result of the Site and WGAT' s reviews, six vulnerabilities were identified for further consideration by the Department of Energy (DOE) Plutonium Vulnerability Working Group preparing the final report. All six vulnerabilities were discussed among the respective site teams members and facility experts and agreement was reached. The vulnerabilities by facility 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 the Argonne National Laboratory-West (ANL-W) and DOE line management organizations that are not explicit Environment Safety & Health (ES&H) vulnerabilities. Zero Power Physics Reactor (ZPPR) The WGAT concurs with the SAT that the plutonium-bearing materials received from other DOE sites are vulnerabilities. The WGAT identified the following additional vulnerability and issues: the ZPPR vault has a vulnerability due to a lack of an up-to-date safety authorization basis; an issue was identified due to a non-conservative and questionable assumption used in the ZPPR vault criticality analysis; and an issue was identified due to the lack of a formal documented plan for inspection and surveillance of the materials in the ZPPR vault. All of the vulnerabilities and issues have a low potential for causing an event with low ES&H consequences if the event was to occur. Transient Reactor Test Facility (TREAD The SAT identified the MK III sodium test loops as a concern. The WGAT considers the MK III sodium test loops to be a vulnerability. The test loops have a low potential for causing an event with low ES&H consequences if an event was to occur. The WGAT found the TREAT facility to be exceptionally well maintained and in excellent operating condition. Analytical Laboratory (AL) The WGAT concurs with the SAT assessment that no vulnerabilities or issues exist in the AL. Experimental Fuels Laboratory (EFU) The WGAT concurs with the SAT assessment that no vulnerabilities or issues exist in the EFL. The SAT identified a concern that the EFL resides in a 30 year old building that has not been confirmed to meet today's seismic design criteria. This concern is under review as part of the AL hot cell restart readiness activities. Nondestructive Analysis Laboratory (NDA) The WGAT concurs with the SAT assessment that no vulnerabilities or issues exist in the NDA Laboratory.
