【 摘 要 】

The Salt Waste Processing Facility (SWPF) requires analyses to verify that strontium and total alpha content of treated wastes meet Saltstone Processing Facility (SPF) Waste Acceptance Criteria (WAC). The SWPF will require that results are available in time to meet process cycle requirements. SWPF personnel sought on-line and at-line monitors to follow trends in strontium-90 and alpha concentrations in order to track process performance. While an on-line method is under development at the Pacific Northwest National Laboratory (PNNL), it has yet to be demonstrated. This report describes off-line methods that will not be subject to some of the concerns about and limitations of on-line/at-line methods. Presently, less-rapid off-line technologies are the baseline methods. Also, this report compares advantages and disadvantages of a variety of approaches including rapid radiochemical separations, automated analytical-scale processing systems, and radiation measurement tools.
