Title: Status report: Carbon-14 in the condensate from the silica gel dryers of the production reactors

Abstract

Volatile compounds containing C{sup 14} produced in the cooling gas systems of Hanford reactors can be lost from the cooling gas by two routes. These are (a) escape via the reactor stacks through leaks in the cooling gas system and (b), adsorption with water vapor on the silica gel of the dryers for the cooling gas with subsequent regeneration of the silica gel and condensation of the water for disposal. Information relative to the release rates by the stack gas route was reported in HW-75618. The present report provides data relative to the C{sup 14} loss rates through the condensate obtained from regeneration of the silica gel dryers of the reactor gas cooling systems. The C{sup 14} containing compounds in the reactor gas are produced by n,{gamma} reaction on the nitrogen in the coolant gas, an n,{gamma} reaction on carbon in the CO{sub 2} component of the coolant gas, or an n,{gamma} reaction on the graphite moderator with subsequent volatilization. Studies are presently under way to determine the contribution of graphite ``burnout`` to the C{sup 14} containing volatile compounds in the coolant gas. Upon completion of these studies a topical formal report will be Issued which will include the findingsmore » on the graphite ``burnout``, the stack gas losses, and the condensate losses.« less
