【 摘 要 】

CH2M HILL Hanford Group, Inc. (CHG) is responsible for developing and maintaining the authorization basis for River Protection Project (RPP) facilities and operations. This responsibility includes closure of the Flammable Gas Unreviewed Safety Question (USQ) for waste tank ancillary equipment such as catch tanks, double-contained receiver tanks, 244-AR and 244-CR vaults, 242-S and 242-T Evaporators, and inactive miscellaneous underground storage tanks. To support closure of the Flammable Gas USQ for catch tanks, an analysis of the flammable gas hazard was performed. This document provides a summary of flammable gas data obtained from RPP active catch tanks in FY 2000. Flammable gas level measurements for each catch tank (other than 241-AX-152) are discussed on a tank-by-tank basis in Section 3.0. Conclusions based on the data are provided in Section 4.0. This section also includes recommendations that would be useful when conducting vapor sampling for other miscellaneous tanks (e.g., inactive miscellaneous underground storage tanks).
