- Abstract
- To meet the Korean new regulation on Level 3 probabilistic safety assessment, the off-site consequence analysis is required for the severe accident of nuclear power plant. To consider socio-environmental characteristics and regulation system for radiation protection in Korea, several important parts in MELCOR Accident Consequence Code System 2 (MACCS2), an off-site consequence analysis code, were modified such as dose conversion factor, shielding factor, inhalation rate, and food chain model. The modified parts were applied to evaluate the accident consequence of a Korean reference nuclear power plant, OPR-1000. As a result, the derived health effect consequences were decreased with reflecting Korean characteristics comparing those with US default values. With the contribution analysis of each factor comparing non-modified MACCS2, the results were decreased with modified shielding factor and inhalation rate, but the result was increased with modified food chain model because of Korean diet habits.
