Design and final safety analysis report for vertical fission product release apparatus in hot Cell B, Building 4501

An existing horizontal furnace and a fission product collection system, used for testing light-water reactor fuel under simulated accident conditions, were rebuilt for operation in the vertical orientation. Major changes in the design of the furnace and in the loading/unloading procedure were required. Modifications to the fission product collection components and the steel containment box for the entire apparatus, however, were relatively minor. Because the fuel specimens, the furnace construction, and the general mode of test operation for this new facility are all similar to those of the previously operated facility, no significant changes in the safety hazards are apparent. Adherence to all quality assurance, personnel training, and operational safety requirements is documented. 16 refs., 10 figs.
