前言工业规模的核能发电厂,在其内用涂料的耐久性方面存在着许多特殊的问题。在这种工厂的设计使用寿命中,涂料应能同时经受高湿和在高温下的累积辐射剂量。另外,涂料还应当是能用除剥离法以外的其他方法消除沾染的,并且在设计的冷却剂事故损失条件下(LOCA)——有时也可叫做设计基本事故(DBA)——有足够的耐久性。应付这些挑战是一门较新的涂料工艺,它有一套精巧的测试和鉴定方法。为了鉴定核能装置初级保护外壳所用的涂料,如果没有实际证实这类试验,是很难作出估计的。
Introduction Industrial-scale nuclear power plants have many unique problems with the durability of their internal coatings. During the design life of this plant, the coating should be able to withstand both high humidity and cumulative radiation dose at high temperatures. In addition, paints should also be capable of eliminating contamination by methods other than lift-off and designed to withstand LOCA - sometimes referred to as Design Basis Accident (DBA) - with sufficient durability Sex. Meeting these challenges is a newer coating process with a sophisticated testing and qualification methodology. In order to identify coatings used in the primary protective casing of nuclear installations, it is difficult to make estimates without actually verifying such tests.
