Abstract

Thermal discharges from the nuclear power plants into neighboring Korean coastal waters have raised serious disputable arguments from the two parties of local fishermen and scientists involved since late 1970's. To meet the social demands and provide scientific and reasonable solutions, new set of standards have been established which will guide through measuring and processing the various variables and parameters in environmental and fishery impact assessment procedures for the thermal discharge from the nuclear power plants. These are made possible for the first time by the combined efforts by Korean Oceanography Society and Fishery Society. In this paper, Thermal Disharge Impact Index(TI) is proposed by the probability of the local temperatures exceeding critically to local fishery multiplied by the weighted sum of diverse environmental and ecological factors. The TI is essentially conceived to overcome the long-exising bad practices based on the particular excess temperature such as 1. The proposed TI based on the guideline principle proposed by the UNEP(2002) is expected to be practical, economic and self-adaptive. To prove the usefulness of the TI, it is highly recommended to conduct prototype experiments and exercises in a particular nuclear power plant site in the near future.

국내 원자력 발전소의 온배수 배출을 둘러싸고 제기된 각 종 수산업 피해 민원이 발생한지도 20년이 가까워 온다. 온배수에 의한 연안환경 및 수산업 피해를 보다 과학적이고 합리적으로 산정하기 위한 지침이 한국 해양학회, 수산학회 공동의 노력으로 마련되었다. 피해역 산정 방안을 보다 합리적으로 마련하기 위하여 기존의 특정 상승온도 기준을 탈피하고 환경과 생태계의 다양한 영향을 포괄적으로 고려할 수 있는 온배수 영향지수를 제안하였다. 이 영향지수는 UNEP(2002)의 권고안에 따른 지침을 수용하고, 현실성과 경제성 및 미래지향적 특성을 갖출 수 있다. 특정 원자력발전소 현장에 적용 가능한 영향지수의 구현을 위하여 예비 실험의 노력이 요구된다.
