Abstract

This study investigated and compared sediment properties and macrobenthic community structures within heated effluent plumes at the discharge areas of Kori Nuclear Power Plant (KNPP) and Sinkori Nuclear Power Plant (SNPP) in Korea, which have different thermal effluent discharge systems. There were significant differences in sand, clay and organic carbon contents between sediments at the two discharge areas. Species richness and abundance of macrobenthos were higher at the SNPP discharge area than at that of the KNPP, although the values at both areas were comparable to previous studies in coastal areas of eastern Korea.

본 연구는 고리원자력발전소와 신고리원자력발전소로부터 배출되는 온배수의 영향을 받는 해역에서 퇴적물 특성과 대형 저서동물의 군집구조를 조사하고 비교하였다. 두 배출해역의 퇴적물 특성들 중에서 모래와 펄, 유기물의 함량이 통계적으로 유의한 차이를 보였다. 대형 저서동물의 출현종과 개체 수는 고리원자력발전소보다 신고리원자력발전소의 배출해역에서 더 많았으며, 그 수는 이전의 다른 연구결과들과 유사한 수준이었다. 두 원자력발전소의 온배수 배출해역은 퇴적물 특성과 대형 저서동물의 출현종 수에서 유의한 차이를 보였다.
