Table 13-3 summarizes radiologicalconditions found during the evaluation <strong>of</strong> the reactor compartment. The lower level <strong>of</strong> the reactorcompartment was sometimes called the secondary shield area because it was an “area” (i.e., volume)enclosed by the secondary shield.Table 13-3 Reactor Compartment Radiological SummaryDeck/compartments Dose rate found Contaminationfound (dpm/<strong>10</strong>0cm 2 )“B” Deck, access area aft <strong>of</strong> reactor Background All < background“B” Deck, area forward <strong>of</strong> reactor Background All < background“C” Deck forward, access from “B” deck Background All < background“A” Deck around cupola Background All < backgroundTop <strong>of</strong> Cupola 4 μR/hour All < backgroundRev.
