Impact Analysis of Nuclear Power Plant Accidents on Reservoir Using Calpuff Model
-
Abstract
Using whole year hourly meteorological data of one site, water contamination caused by radioactive plume release after accidents of NPPs was modeled using Calpuff model. The results showed that, it was more reasonable using realistic meteorological data like wind direction and precipitation etc, and concentration of radioactivity in the reservoir caused by postulated accidents for sitting and IC release category was much lower than the genetic action levels for foodstuffs in GB 18871-2002. But the concentration of radioactivity caused by BP release category was still higher than the genetic action levels for foodstuffs in GB18871-2002 despite using realistic meteorological data, so such sever accidents should be avoid in design.
