LEAKAGE CHARACTERISTICS OF OPENINGS FOR REACTOR HOUSING COMPONENTS

Measurements were made of the air leakage rates through structural components that penetrate semicontainment reactor housing installations. Full- sized test specimens were sealed inside a 10-ft-diameter test sphere, and the leakage rate was measured as a function of pressure for pressure differentials of up to 25 in. of water. The data were fitted to empirical equations that describe the leak rate at any pressure differential within the range of the experimental tests. The forms of the equations are such that the total leak rate of a building can be obtained by summing the empirical constants and multiplying by a probable pressure differential. (auth

RADIOISOTOPIC INVESTIGATION OF OMR COOLANTS. PART I. OMRE OPERATION, JANUARY 1958-AUGUST 1960

Over 30 radioisotopes were identified in the coolant of the OMRE during the period from January, l958 through August, l960. The principal gamma-emitting isotopes measured were the corrosion products: Mn/sup 56/, Fe/sup 59/ and Mn/sup 54/ the principal beta emitters were: P/sup 32/, H/sup 3/,S/sup 35/, Fe/sup 55/, and C/sup 14/. The total (gamma plus beta) activity of the coolant during normal reactor operations was estimated to have been less than l.08 mu c/gm of coolant, with Mn/sup 56/ contributing approximately 80% of the detected process radiation.
