The structural design methods for LWRs described in Chapter 5 are applicable to the components subjected to low temperatures for which creep effects can be neglected. On the other hand, the operating temperatures of fast reactors include the range potential creep deformation. In addition, elevated temperatures imply that a larger temperature gradient exists with structures at low temperature, causing more severe thermal stress. Consequently, different failure modes than those affecting the LWRs have to be taken into account when designing fast reactor components subjected to high temperatures.

摘要

The structural design methods for LWRs described in Chapter 5 are applicable to the components subjected to low temperatures for which creep effects can be neglected. On the other hand, the operating temperatures of fast reactors include the range potential creep deformation. In addition, elevated temperatures imply that a larger temperature gradient exists with structures at low temperature, causing more severe thermal stress. Consequently, different failure modes than those affecting the LWRs have to be taken into account when designing fast reactor components subjected to high temperatures.
