“…The Li and Ni results on cores 64 and 65 were reported and discussed in Bell (1995a). For core 121, the ICP analytes of A1 and Na were required for historical waste modeling per the historical data quality objective document (Simpson and McCain 1995), Li was required to evaluate contamination by wash water used to clear the drill string, and Ni was required per the ferrocyanide DQO (Meacham 1995). Additional ICP data from cores 64, 65, and 121 were collected on an opportunistic basis and are reported here.…”

“…The results were reported in Bell (1995b) and Bell (1995~). The saltcake in core 121 was analyzed to satisfy the requirements of the historical DQO document (Simpson and McCain 1995). However, this DQO does not include Sr-90 with respect to historical evaluation of the BY Saltcake waste type; it is requested for historical evaluation of the ferrocyanide sludge waste type, which was not recovered from core 121.…”

“…Selected analytical results from core 121 were evaluated against the Historical DQO (Simpson and McCain 1995) and indicate that the saltcake in tank BY-I06 is of the waste type "BY Saltcake" (Agnew 1995).…”

“…Sample S96T000253 from the lower half of segment 10 of core 121 had an FWD of 40.2% and sample S96T000381 on the core composite had a RPD of 16.7%. These samples were not re-run since the 10% criterion was not grossly exceeded in any case and because the sample clearly had enough Na to allow classification as "BY saltcake" per Simpson and McCain (1995). (See Section 5.0.…”

The Hanford Site has 177 underground high-level radioactive waste storage tanks in 18 tank farms. The tanks contain accumulated liquid, sludge, and saltcake wastes from more than 50 years of nuclear weapons material production activities at the Hanford Site. Several types of waste exist in the tanks, and the tank contents vary from homogeneous to highly heterogeneous. The tanks also have a variety of important safety, disposal, regulatory, and operational issues associated with them. In addition to the 177 tanks, several double-contained receiver tanks (DCRTs), catch tanks, and inactive miscellaneous underground storage tanks (IMUSTs) are also in the purview of Tank Waste Remediation Systems (TWRS).This document establishes an approach to determine the priority of tank sampling at the Hanford Site. The approach is based on data quality objectives (DQOs) and other requirements documents for each issue identified, as well as tank priority inputs from each of the TWRS programs. The DQOs (or other requirements documents) used to direct characterization for each of the issues are listed below:Flammable gas (Bauer and Jackson 1997) Sluicing of tank 241-C-106. The characterization requirements are documented in a process control plan (Carothers et al. 1998).Waste feed delivery (Phase I). Characterization requirements will be documented in problem-specific DQOs, one to confirm the selection of tanks to supply low-activity waste (Certa 1998) and one to confirm the selection of tanks to supply high-level waste, to be issued by May 1998 (problem-specific DQOs #1 and 2, respectively). Ten other problem-specific DQOs will be written (#3 -10 and 13 -14). A decision will be made Es-1 HNF-SD-WM-TA-164 Rev. 4 later to determine which of these 10 problem-specific DQOs will require characterization sampling, if any. Problem-specific DQO #11 will probably be canceled because its requirements are covered by the Privatization low-activity waste DQO (Wiemers and Miller 1997. See next bullet). Problem-specific DQO #12 will be canceled because no further information is required (Murkowski 1997). In addition to the problem-specific DQOs, the retrieval DQO (Bloom and Nguyen 1996) and the mixer pump test plan (Staehr 1996) will be used to direct sampling and analysis of tank 241-AZ-101. The retrieval DQO will be transitioned out of use, to be replaced by the problem-specific DQOs. The mixer pump test plan is being updated to ensure that required data will be obtained and that sufficient detail will be provided to direct sampling and analysis.
