Abstract

Numerical simulations were performed to evaluate the dispersion characteristics of the pollutant around a Wolsung coastal area at located nuclear power plants. Numerical experiments by using EFDC(Environmental Fluid Dynamics Code) showed good agreements by comparison with the time series and harmonic analysis of the tidal elevations. The released pollutants moved in north direction at flood tide and in south direction at ebb tide. The calculated salinity and temperatures showed good agreements with the observed results by NFRDI(National Fisheries Research & Development Institute). The water circulation due to the variations of the temperature, salinity and tidal components were analyzed to estimate the dispersion characteristics of the pollutant.

원전이 위치한 동해 월성 연안역 주변에서 오염물 이동 확산에 대한 수치 모사를 수행하였다. 월성 연안역의 유속장 재현을 위한 해수유동 수치모형 실험은 EFDC(Environmental Fluid Dynamics Code) 모델을 사용하여 조위 시계열 검증 및 조화분석을 통한 검증을 실시한 결과 양호한 재현성을 나타내었다. 월성 주변해역의 유속장 산정 결과 창조류시에는 남향, 낙조류 시에는 북향으로 진행되는 결과를 알 수 있었다. 또한 국립수산과학원에서 관측한 수온, 염분의 자료를 이용하여 수치모델을 통한 계산값과 관측값을 비교한 결과 양호한 재현성을 나타내었다. 계산된 해수유동자료와 수온, 염분의 결과를 이용하여 오염물질의 확산특성을 해석하였다.
