REACTOR PRESSURE VESSEL, REACTOR AND REACTOR PRESSURE VESSEL PRODUCTION METHOD

摘要

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
