Claims (6)
- 열관을 포함하는 파이프에 의해 서로 연결된 원자로 압력 용기 및 최소한 하나의 증기 발생기로 구성된 원자로 냉각 시스템(RCS)을 진공 탈개스 하기 위한 방법에 있어서, 상기 RCS는 열관의 대략 중간 부분 아래에서 배출되는 반면 환기되지 않는 상태로 유지되며, 배출된 어떠한 원자로 냉각재로 증기 발생기의 1차축에서 응축되며, 비 응축성 개스로부터 배출되어 원자로 냉각재가 열 제거 시스템을 통해 순환하는 것과, 마지막으로 RCS를 배출하고 그로부터의 어떠한 개스도 제거하기 위해 RCS상에 진공이 형성되는 것을 특징으로 하는 원자로 냉각재 시스템의 진공 탈개스 방법.
- 제1항에 있어서, 배출중 2상 펌프에 의해 환기되지 않은 RCS에 부분 진공이 형성되는 것과, 상기 부분 진공은 배출 단계중 탈개스를 야기하기 위해 RCS내의 지배적인 온도에서 원자로 냉각재를 비등시키기에 충분한 것을 특징으로 하는 원자로 냉각재 시스템의 진공 탈개스 방법.
- 제1항에 있어서, 상기 배출된 냉각재는 중기 발생기의 2차측을 통해 흐르는 2차 냉각재에 의해 응축되는 것을 특징으로 하는 원자로 냉각재 시스템의 진공 탈개스 방법.
- 제1항에 있어서, 상기 진공은 냉각재의 배출후 그리고 열제거공정이 시작된후에 형성되는 것을 특징으로 하는 원자로 냉각재 시스템의 진공 탈개스 방법.
- 제1항에 있어서, 열제거 시스템내에서 순환하는 원자로 냉각재를 샘플링하는 단계를 포함하며, 배출을 샘플링중 설정된 낮은 레벨의 개스 농도가 측정될때까지 유지되는 것을 특징으로 하는 원자로 냉각재 시스템의 진공 탈개스 방법.
- 제1항에 있어서, 원자로냉각재는 개스 제거를 위해 순환하는 동안 혼합층 탈광석기로 펌프되는 것을 특징으로 하는 원자로 냉각재 시스템의 진공 탈개스 방법.
