Abstract

The exhaust ventilation air from nuclear power plants and other nuclear facilities is carefully filtered, as aerosols are a potential vector of contamination. Monitoring the condition of the air filters improves radiation safety. In this paper the progression of differential pressures over air filters at a nuclear research reactor have been studied. Technical properties and possible environmental influences have been checked in order to understand the variation of the pressure over time. The differential pressure has been decomposed into different components as a result of an analysis of environmental conditions. The gradually increasing component, representing gradual accumulation of aerosol particles in the filter, is modeled as a gamma process and an estimate for determining the remaining useful life of the air filters has been computed.
