Abstract
This paper attemps to simulate the characteristic parameters of the oxide film formed during plant operation at the outer surface of nuclear reactor vessel,such as roughness,surface topography,phase composition,layer stucture,oxidative weight gain rate.By doing high temperature oxidation simulating test on reactor vessel material,and comparing the difference between samples with various original states,to acquire the oxidation product similar to the actual situation.The analysis showed that the reactor vessel material is completely antioxidant,and there is difference between the data of samples uncorroded before high temperature test and the data of corroded ones,thus giving effective data for the solution of molten corium in-vessel retention (IVR).关键词
