LEAKAGE OF RADIOACTIVITY DURING TRANSPORTATION OF DEFECTIVE FUEL AND THE FEASIBILITY OF A DOUBLE-CONTAINMENT SYSTEM

LEAKAGE OF RADIOACTMTY DURING TRANSPORTATION OF DEFECTIVE FUEL AND THE FEASIBILITY OF A DOUBLE-CONTAINMENT SYSTEM: ANALYTICAL AND EXPERIMENTAL EVALUATION. In order to study the issue of the safe transport of defective spent fuel, the following studies were carried out for LWR fuel contained in a wet-type container. (I) An analytical evaluation, using a scenario and model, of the leakage of radioactive materials from defective fuel and an experimental evaluation of dummy defective fuel with the aim of defining the source term. (2) A theoretical evaluation of th.e feasibility of a double-containment system in order to establish the transport container's leaklightness.
