LITERATURE SURVEY FOR ACTIVITY BUILD-UP ON REACTOR PRIMARY SYSTEM COMPONENTS
Abstract
A survey was made of the possible build-up of longlived radioactivity on primary system components with increased reactor operation. Parameters and mechanisms that may contribute to this activity build-up are discussed. The activity build-up was attributed to either deposition and/or atom exchange. Experimental data to-date is not sufficient to conclusively attribute the degree to which each of these mechanisms contribute to the build-up. The need for experimental information, especially for reactors employing stainless steel clad fuel elements, is discussed. Theoretical equations to predict the extent of the activity build-up are discussed. To-date these equations have not been accurate in predicting the build-up of long-lived nuclides. Decontamnation of primary system components may be required to remove this build-up. A discussion of present-day decontamination agents and their application is discussed. (auth)
