Accident Analysis for the Plutonium Finishing Plant Polycube Stabilization Process.

Abstract The Polycube Stabilization Project involves low temperature oxidation, without combustion, of polystyrene cubes using the production muffle furnaces in Glovebox HC-2 1 C located in the Remote Mechanical 'C' (RMC) Line in Room 230A in the 234-52 Facility. Polycubes are polystyrene cubes containing various concentrations of plutonium and uranium oxides. Hundreds of these cubes were manufactured for criticality experiments, and currently exist as unstabilized storage forms at the Plutonium Finishing Plant (PFP). This project is designed to stabilize and prepare the polycube material for stable storage using a process very similar to the earlier processing of sludges in these furnaces. The significant difference is the quantity of hydrogenous material present, and the need to place additional controls on the heating rate of the material. This calculation note documents the analyses of the Representative Accidents identified in Section 2.4.4 of Hazards Analysis for the Plutonium Finishing Plant Polycube Stabilizution Process, HNF-7278 (HNF 2000). These two accidents, 'Deflagration in Glovebox HC-21C due to Loss of Power' and 'Seismic Failure of Glovebox HC-21C', will be further assessed in this accident analysis.
