Description/Abstract:
An analysis is made of the integrity of the SGR in its present design. The response of the reactor and surrounding material environment to nuclear incidents ranging in magnitude from those of minor consequence to those of explosive magnitude is studied. It is concluded that the present design, with slight modification, will not release radioactive by-products of a 3s incident to the atmosphere. This conclusion is made assuming the 3s incident (dk = 0.02) occurs as a step function. It is concluded that in order to obtain an explosive type reaction, one would require reactivity increments which are absurdly large and that the probability of such an event, sans sabotage, is essentially zero. It is concluded that the present design contains features which could lead to non-containment of a 3s incident and suggestions are preferred for the elimination of such a consequence and to the upgrading of the reactor integrity status such that a steel shell type reactor building for the containment of a 3s (and perhaps greater) incident appears unnecessary.
