Capsule Characterization Report for Capsule Dry Storage Project
There are 1,936 cesium (Cs) and strontium (Sr) capsules stored in pool cells at the Waste Encapsulation and Storage Facility (WESF). These capsules will be moved to dry storage on the Hanford Site as an interim measure to reduce risk. The Cs/Sr Capsule Dry Storage Project (CDSP) is conducted under the assumption that the capsules will eventually be moved to the repository at Yucca Mountain, and the design criteria include requirements that will facilitate acceptance at the repository. The storage system must also permit retrieval of capsules in the event that vitrification of the capsule contents is pursued. The purpose of this report is to (1) develop performance criteria for the capsules to ensure that the capsules fall within the design and safety basis prior to being placed into the storage; (2) evaluate the current integrity of the capsules to determine whether they can be safely handled and loaded into dry storage system overpacks; and (3) establish criteria and evaluate the integrity of the capsules at the end of the 50-year dry storage life to assess whether they can be retrieved safely from the overpacks, if required. The evaluations are based on reviews of existing capsule documentation, results of capsule inspections and testing performed at WESF, and corrosion studies assessing current capsule conditions and predicting the extent of future capsule degradation.
