A Comparative Study on the Methodology of Quantitative Health Objectives

The government policy on severe accident of nuclear power plant was issued on Aug. of 2001. A QHO (quantitative health objective) was proposed as a safety goal in the policy but there wasn't much study on what it means quantitatively this QHO. The QHO which can be represented as 0.1% early fatality due to an accident was adopted from the NRC safety goal and the consequence of this 0.1% early fatality for Korean NPPs hasn't been evaluated yet. Thus the technical basis and quantification procedures for these quantitative health objectives for domestic nuclear power plants need to be evaluated. In this paper we have assessed an acceptable risks based on the mortality of Koreans to compare with the QHO of government policy. Also we have surveyed how the foreign QHOs were developed and compared the results with our domestic objective.
