CORROSION PRODUCT ACTIVITY IN THE PRIMARY SYSTEM OF THE ARMY PACKAGE POWER REACTOR

Abstract

S>Experimental work has been penformed to determine the extent and mechanism of the buildup of activated corrosion products in tbe primary system of the Army Package Power Reactor. The results of radiochemical analyses of water and crud sampled from tbe primary system, and of deposits removed from the surface of metal test specimens exposed to the primary coolant are presented. In addition, the dose rates measured during reactor shutdown at the externnl surfaces of primary system components are reported. Water, crud, and deposits from the metal test samples were annlyzcd for long-lived gamma emitting nuclides oniy. Data are presented on the specific activity of these samples and the nuclide ratios of these specific activities. The buildup of activity on the surface of the metal specimens is shown to be related to time of exposure, temperature of the coolant, and the type of steel specimen used. (auth)
