Pu ES&H Vulnerability Assessment Hanford Site EXECUTIVE SUMMARY The Secretary of Energy's memoranda of January 24 and March 15, 1994, established an initiative for a Department-wide assessment of the environmental, safety and health vulnerabilities of fissile material storage, with the first step being the establishment of a Plutonium Vulnerability Assessment Working Group. The Project Plan for this first step in the fissile material initiative was issued on April 25, 1994 by U.S. Department of Energy, Office of Environment, Health and Safety (EH). A sub-element of the Working Group will manage the assessments and produce an integrated report for the Secretary by September 30, 1994. This Working Group sub-element is referred to as the Support Group and has membership from each of the Working Group Assessment Teams. This report was prepared by the Richland Working Group Assessment Team (WGAT) assigned to the Hanford Site. Oversight and coordination of this assessment was provided by the Department of Energy-Richland Operations Office CDOE-RL). The WGAT's assessment activities were conducted June 6-30, 1994 and included eighteen Hanford Site plutonium facilities. The primary objective of the WGA T site visit was to review, verify and validate plutonium environmental, safety, and health vulnerability information presented in the Hanford Site Assessment Team (SAT) Report prepared by Westinghouse Hanford Company (WHC) and the Battelle Memorial Institute Pacific Northwest Laboratories CPNL) and to identify any additional vulnerabilities not identified by the site. Another objective was to ensure that stakeholders were involved to the extent feasible in this effort. Local stakeholders were informed of the plans for and results of the SAT and WGA T activities. In addition, they had an opportunity to provide additional comments from their perspectives and to join the verification and validation activities of the WGAT. This plutonium ES&H vulnerability assessment included all forms of plutonium at Hanford under the DOE's custody or control except plutonium in irradiated nuclear fuel and plutonium waste forms which are the subject of other DOE programs. Hanford plutonium facilities contain over 4.3 metric tons of in-scope plutonium distributed among 8,800 items. The vast majority of the plutonium materials are located in vaults, vault-type rooms, gloveboxes, and other authorized secure locations. Plutonium is also found in the form of holdup in various locations, including areas where residual plutonium is normally expected (gloveboxes, process piping and equipment, and ventilation ductwork) and areas where it is not normally expected (retired plutonium buildings modified for office space and downstream of filter plenums).
