High level waste tank farm solid waste radionuclide smear sample and analysis plan

The HLW Tank Farm Low-Level Solid Waste Radionuclide Smear Sample And Analysis Plan has been written to describe the three methods by which the HLW Tank Farm facilities will obtain analytical data of radionuclide distribution in, and activities of, solid waste generated in the Tank Farms for waste certification and delivery to the Low Activity Waste Vaults (LAWV) in E Area. Results will be used as a possible confirmatory supplement to process knowledge as contained in the document, WSRC-TR-94-0290, {open_quotes}High-Level Waste Characterization In Support Of Low-Level Waste Certification, I. HLW Supernate Radionuclide Characterization.{close_quotes} The purpose of collecting samples is to obtain analytical data to supplement the validation data from WSRC-TR-94-0290 that gives radionuclide distributions for low-level job control waste characterization. It is expected that the results received from the laboratory will not enable quantification within the existing WAC limits but will be used only to possibly supplement the validation of years of determinations made based on process knowledge and sampling the High Level Waste (HLW). This occurs because several of the nuclides in the WAC 3.10 list are either expected to be present in such low abundance and/or have such a soft radiation (e.g., low energy beta) that even themore » most sensitive laboratory techniques cannot detect their presence and measure their abundance.« less
