LLNL Plutonium ES&H Vulnerability Site Self Assessment 1.0 EXECUTIVE SUMMARY The objective of the Lawrence Livermore National Laboratory Site Plutonium ES&H Vulnerability Assessment was to assess the plutonium holdings at LLNL for any conditions or weaknesses that could lead to unnecessary or increased radiation exposure of the workers, release of radioactive materials to the environment, or radiation exposure to the public. The information developed by the site assessment team will provide background information to the working group assessment team about the site and its plutonium holdings and will provide preliminary findings of potential vulnerabilities. The LLNL site was divided into four primary facility holding areas. These were: • Building 332(B332), the LLNL Plutonium Facility • Building 251 (B251), the Heavy Element Facility • Building 231 (B231), the Sealed Source Vault • LLNL, Sitewide, for sealed sources outside a specific vault location. Six material aggregate areas were identified within these facilities: • B332 Storage Vaults • B332 Gloveboxes and Ventilation Systems • B332 co-located TRU drums •B251 •B231 • LLNL Sitewide Sealed Sources The site self assessment found 6 concerns related to plutonium storage, handling, processing, and or shipping at the LLNL. They include, in LLNL site-wide rank order: 1. #LLNL/332-02 -- material packaged in non-standard container packaging with inadequate knowledge of the packaging methods employed in B332. 2. #LLNL/251-01 --material packaged in non-standard packaging with inadequate knowledge of the packaging methods employed in B251. 3. #LLNL/332-03 -- The questionable seismic adequacy of some internal structures, systems, and components (SSCs) increases the likelihood of worker contamination in the event of a design basis earthquake. This includes two internal walls and a portion of the fire suppression system within the building. 4. #LLNL/Sitewide Sources and B231-01 -- sources in non-standard encapsulation with inadequate knowledge of the encapsulation methods. 5. #LLNL/332-01 -- the unnecessary dose created by excess material. 6. #LLNL/Sitewide Sources and B231-02 --the low yet unnecessary dose created by excess sealed sources.
