Aerosol Behavior Research Implications of Chernobyl

Abstract

The mechanistic determination of the transport of fission products associated with LWR severe accident analyses largely involves application of aerosol behavior technology. Of course, then, the Chernobyl accident should be assessed to determine if there are any possible implications regarding the status or the technology and the safety research needs with respect to aerosols. This paper presents a brief overview of the status of aerosol behavior modeling in LWR safety and gives an opinion on the research needs. By comparing the aerosol behavior aspects of the Chernobyl accident, a judgment is made that the accident does not change this perception of the status of the technology or of the research needs but does suggest some areas in- directly associated with aerosols where additional research could be beneficial.
