【 摘 要 】

The testing reported here was performed on K East Basin consolidated sludge samples to generate data needed for the evaluation and design of the systems that will be used to disposition the K Basin sludge to T-Plant for interim storage. The tests were conducted by Pacific Northwest National Laboratory from May through November 1999 under the direction of the Spent Nuclear Fuel (SNF) Project. The samples used in the work discussed here were collected by the SNF Characterization Project from the KE Basin floor and canisters during March and April 1999. These samples (3 from the floor and 3 from the canisters) were shipped to the storage pool at the Postirradiation Testing Laboratory (327 Building) and later transferred to the PNNL Radiochemical Processing Laboratory (325 Building), where they were recovered for testing and analysis. Testing activities presented in this report include particle size measurement via wet sieving, sludge settling and sludge density measurements, sludge shear strength measurement, and measurement of sludge dissolution enthalpy to ascertain the uranium metal content of the sludge. Section 1.0 provides the summary and conclusions to date. Section 2.0 describes the consolidated sample container system, the sample collection and transfer, inspection, and recovery of the samples for testing. Section 3.0 describes the testing methodologies and presents the results and analyses.
