a The radioactive materials inventories for the selected facilities were obtained from LLNL in July 1991. These inventories were further modified by laboratory input to reflect October 1991 quantities. Therefore, some radioactive materials listed in building descriptions may not be present in the facility in October 1991 and hence do not appear in this table. This table shows typical quantities rather than maximum limits. These radioactive materials are subject to change as laboratory experimental requirement change.
b Calibration (sealed) sources in Building 801 include Cs-137, Na-22, Ra-226, and Ir-122. Detection (sealed) sources in B-801 include H-3.
c Buildings 801, 850, and 851 may contain thorium, depleted uranium, and/or tritium. The quantities depend on experimental shot.
d Building 823 may contain natural and depleted uranium.
e Building 836 may contain natural and depleted uranium, and thorium.
f Building 854 may contain natural and depleted uranium, and thorium.
g The LLNL Site 300 administrative limit for plutonium is 15 kg, for tritium is 0 kg, and for enriched uranium is 130 kg. The components containing plutonium and enriched uranium are sealed and certified; special precautions are taken to ensure no external contamination can occur. LLNL Site 300 tritium use would resume FY 1993 at the firing tables with an administrative limit of 20 mg. LLNL Site 300 has no limit for the use of depleted uranium.

a The chemical inventories presented in this table were obtained from the 1989 data base used to prepare the LLNL Livermore Site Hazardous Material Business Plan for Alameda County, and were limited to the selected facilities described in this Appendix A. The list was updated to reflect July 1991 quantities. This extensive list within each selected facility was reduced further, and was limited to extremely hazardous chemicals greater than 1 lb and all other chemicals greater than 500 lb. Some chemicals listed in the building descriptions may be used in smaller quantities and may not appear in this table. This list represents typical laboratory chemicals and quantities and does not represent maximum limits, and the quantities are subject to change as laboratory experimental requirements change. The total LLNL Livermore site chemical quantity is listed in Table 4.15-1.
b Summary of Extremely Hazardous Substances, Report Date: 03/06/91 (updated June 1991).
c All quantities measured in pounds unless indicated otherwise.
d The maximum ethanol inventory within B-490/492 is 3500 gal. When fresh ethanol is delivered, it comes in a 7000-gal tanker that is parked next to the facility for a short period of time.
e The three propane tanks are normally kept empty and only one tank is filled, or partially filled, with liquid propane for curtailments, testing, and training. The tank sizes are 30,000 gal each.
f A toxic gas cabinet is planned to be installed in Building 222. It will contain two of the following three gases: HCN, H4N, H2S, in 9" × 51" 1A cylinders.
