The Experience and Analysis of Radiological Protection at KoRi Unit #1, Nuclear Power Plant

원자력(原子力) 1 호기(號機)의 방사선관리경험(放射線管理經驗)과 평가(評價)

The analysis of radiological protection at Kori Nuclear Unit #1, which started commercial operation on April 29, 1978, has been carried out in three areas, namely, radiation exposure, radioactive waste disposal and environmental management. The analysis results for radiation exposure and radioactive effluent releases appear to increase gradually with plant operating years. On the other hand, the apex of radiation exposure and radioactive effluent releases was in 1983 and 1982 respectively and then decreased or stabilized. Also, the operation environmental radioactivity seems to be no higher than preoperation environmental radioactivity.

1978년(年) 4월(月) 29일(日) 상업운전을 개시한 원자력(原子力) 1 호기(號機)의 방사선관리실태放射線管理實態)를 방사선피폭(放射線被爆), 방사성폐기물(放射性廢棄物) 및 환경관리(環境管理)로 구분고찰(區分考察) 하였다. 그 결과(結果) 방사선피폭(放射線被爆)과 방사성폐기물(放射性廢棄物)은 발전소(發電所) 운전년수(運轉年數)에 따라 점차(漸次) 증가현상(增加現象)을 나타내더니, 1983 및 1982 년도(年度)를 정점(頂點)으로 감소(減少) 또는 안정추세(安定趨勢)를 나타냈다. 그리고 발전소 가동후(稼動後)의 주변환경방사능(周邊環境放射能)도 발전소 가동전(稼動煎)보다 높지 않은것으로 나타났다.
