The radiation survey of the Blanket Exit Water Instrumentation assemblies Core I, Seed 1 was performed on January 15 and 16, 1960, approximately 100 days after reactor shutdown at 5806 EFPH. The observed radiation levels varied with height from 150 to 500 mr/hr; the highest activity was found at the bottom of both support tubes of each of the four assemblies monitored, which, in operation, would be located 5 in. above the top of the blanket fuel assembly. The two inner port Blanket Exit Water Instrumentation units and the two Auxiliary Seed Exit Water Instrumentation assemblies were not monitored. (D.L.C.
