Operational assessment of the transnuclear TN-9 truck spent fuel shipping cask: studies and research concerning BNFP

This report presents the results of an operational assessment of the Transnuclear Inc., TN-9 spent fuel cask. This packaging system transports seven current generation boiling-water-reactor nuclear fuel assemblies in a truck shipping mode. The studies were performed at the Barnwell Nuclear Fuel Plant by employees of Allied-General Nuclear Services. The work was funded by the Department of Energy during fiscal year 1981. The cooperation of Transnuclear in this effort is gratefully acknowledged. The study is based on repeated simulated unloading runs of TN-9. Specific tasks and areas of study included: (1) sequential dry-run handling operations under simulated unloading conditions, (2) detailed time and manpower studies, (3) estimates of operator radiation exposure, (4) a general evaluation of the cask system capabilities as they relate to unloading and loading facility operations, and (5) preparation of operating procedures for both unloading (confirmed by practice runs) and loading (yet to be confirmed). Also included is general information on the cask, auxiliary equipment, and the Certificate of Compliance
