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.
