Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a reactor pressure vessel which ensures both high anticorrosion and resistance against core melt.SOLUTION: The reactor pressure vessel has a ceramic coating on the inner surface at least partially. The reactor pressure vessel can be produced by forming the ceramic coating on the inner surface of the reactor pressure vessel body made of low alloy steel under the condition that the temperature of the reactor pressure vessel does not reach 1000°C.SELECTED DRAWING: Figure 1
【課題】高い耐食性と炉心溶融物に対する抵抗性とを兼ね備えた、原子炉圧力容器を提供する。【解決手段】本実施形態による原子炉圧力容器は、内面の少なくとも一部にセラミックコーティングを備えたことを特徴とするものである。この原子炉圧力容器は、低合金鋼からなる原子圧力容器本体の内面に、前記原子炉圧力容器の温度が1000℃以上にならない条件下でセラミックコーティングを形成させることで製造することができる。【選択図】図1 |
