Natural removal of particulate radioactivity in an LWR-containment during core meltdown accidents

  • 1. Lab. for Aerosol Physics and Filter Tech., Kernforschungszentrum, Karlsruhe, Germany

Description

During core meltdown accidents in LWRs, large quantities of fission products and core material are vaporized and released to the containment in particulate form. The behavior and the natural removal of this aerosol is calculated with the computer code NAUA. Airborne aerosol mass in the containment and leaked masses are calculated for a typical accident sequence in the German PWR. Additionally, the influence of a containment failure on the total environmental impact is evaluated as a function of time. It is demonstrated that a period of three days of containment integrity is required to minimize the aerosol mass which escapes from the containment
