11 nov 1960 anni - Strips of Cadmium were Inserted in two of the T-rod Control Shrouds due to Reduced shut-down margin resulting from the boron loss

Descrizione:

She banked rod position, with the reactor cold, was determined at-an exposure of 711 MWD, but not thereafter. The last part of the curve for the cold condition is an assumption of cold reactivity behavior, based on the observed
behavior of the banked rods during equilibrium operation at 2.56 MWT. Thus, the effect of the cadmium at 2.56 MWT was observed to be approximately 1% in reactivity, and this was assumed to also be the case with the reactor cold.
