ASME核电建造规范对材料韧性的要求

Requirements for Tough Material Used in Nuclear Power Plants per Section Ⅲ,Division 1 of ASME

鉴于核电设备的重要性及其高度潜在危险,ASME规范对核电设备建造规定了远高于普通压力容器的韧性要求和特殊试验方法。以核1级和核2级部件的要求为例,介绍了ASME规范在这方面的规定。

As the great importance and the highly potential hazards of the equipment used in the nuclear power plants, the much more higher acceptable standard and unique test procedures are set forth in the ASME nuclear mechanical component construction code for the toughness of materials in contrast with the pressure vessels. Taking NB and NC subsections as examples, provi- sions in this respect was introduced.
