TA-16 during 1999, 2000, and 2001. Upgrade of a part of the WETF roof to meet current seismicrequirements was begun in November 2000 and was completed in March 2001. This modification involvedadditional structural attachment of the existing roof to the facility walls. NEPA review for the re-roofing wasprovided by Categorical Exclusion (DOE 1998b). A new WETF office building (Building 824) was completedin November 2001. This work was also done under a Categorical Exclusion (DOE 1998c).During 2002, there were no new major construction activities or building modifications at WETF at TA-16. The operational readiness review to extend the tritium processing area of WETF into Building 450 wasstarted in 2002. At the completion of the operational readiness review, Building 450 will be integrated intoWETF tritium operations. The modification of Building 450 is to accommodate neutron tube target loadingoperations and related research. This modification was addressed by the SWEIS ROD and has its own NEPAcoverage via an environmental assessment and Finding of No Significant Impact (DOE 1995a).Actual for TSTA and TSFF: A new cooling tower was installed to replace the original TSTA coolingtower at TA-21 (DOE 2000b). This reduced the amount of tritium released into the LANL liquid radioactivewaste system. No other modifications to either TSTA or TSFF were made during the period 1996–1998. InNovember 1999, DOE determined that the TSTA facility has completed its mission and the tritium will beremoved from TSTA in the next several years. During 2001, only a limited experimental program was carriedout in TSTA, and this program was completed by June 2001. There were no facility modifications made tothe TA-21 facilities from 1999 through 2002.A summary of construction and modification activities is presented in Table 2.2.1-1.2.2.2 Operations at the Tritium FacilitiesThe SWEIS identified nine capabilities for this Key Facility. No new capabilities have been added, andone, Cryogenic Separation at TSTA, has been deleted. Table 2.2.2-1 lists the nine capabilities identified in theSWEIS and presents CY 1998 through CY 2002 operational data for each of these capabilities. Operationsin 1998 through 2002 were below the SWEIS ROD projections and remained within the establishedenvironmental envelope. For example, in 2002, 25 High-Pressure Gas Fill operations were conducted(compared to 65 fills projected by the SWEIS ROD), and approximately 20 gas boost system tests and gasprocessing operations were performed (compared to 35 projected).Tritium water collection drums2-46SWEIS Yearbook—2002
