Description
以下、本発明の実施形態であるBWRプラント冷却水への亜鉛注入方法、及び、そのシステムについて、図を参照して詳細に説明をする。
本発明者らの評価により、亜鉛は酸化性環境より還元性環境で特に酸化皮膜に取り込まれやすいことが判明した。したがって、本実施形態では、起動時に水素注入を適用すると同時に亜鉛注入を併用し、第1実施形態の亜鉛注入以上の線源低減効果を達成する。
101:亜鉛供給タンク
102:攪拌装置
103:亜鉛注入ポンプ
104:制御盤
Claims (2)
- 沸騰水型原子力プラントの冷却水へ亜鉛のみを注入し、前記亜鉛の注入は、新生面を有する配管に対して行い、前記新生面に酸化皮膜を前記亜鉛を取り込ませながら成長させ、
前記沸騰水型原子力プラントの起動時に前記冷却水へ水素をさらに注入し、
前記冷却水へ注入する水素の量を、前記冷却水温度が一定の状態にある場合には、前記冷却水温度が上昇の局面にある場合より、注入量を大きくし、かつ、前記冷却水温度が高くなるにつれ注入量も大きくすることを特徴とする沸騰水型原子力プラント冷却水への亜鉛注入方法。 - 沸騰水型原子力プラントの冷却水へ亜鉛のみを注入する亜鉛注入部を有し、前記亜鉛注入部による前記亜鉛の注入は、新生面に酸化皮膜を前記亜鉛を取り込ませながら成長させるために、前記新生面を有する配管に対して行い、
前記沸騰水型原子力プラントの起動時に前記冷却水へ水素を注入する水素注入部をさらに有し、
前記水素注入部は、前記冷却水へ注入する水素の量を、前記冷却水温度が一定の状態にある場合には、前記冷却水温度が上昇の局面にある場合より、注入量を大きくし、かつ、前記冷却水温度が高くなるにつれ注入量も大きくすることを特徴とする沸騰水型原子力プラント冷却水への亜鉛注入システム。
