radiation fatigue

The major aging problems in a PWR plant and their assessment technologies were summarized as the radiation embrittlement of reactor pressure vessel materials, thermal aging of cast stainless steel, stress corrosion cracking of steam generator tubing and metal fatigue in primary circuit of a PWR plant.

主要的老化机理有反应堆压力容器的辐照脆化、铸造不锈钢的热老化、蒸汽发生器传热管的应力腐蚀开裂和金属疲劳。因而可能是一种潜在的辐射防护剂。

Usually, the key components of large scientific facilities work in the extreme environment with high temperature, high pressure, intense radiation and fatigue loads, and prone to fatigue failure.

大科学装置中的关键零部件经常处于高温、高压和强辐射的极端环境中，承受着疲劳载荷，容易发生疲劳破坏，在设计阶段就需要重视疲劳破坏问题。

Side effects of radiation therapy may include mild skin problems or fatigue.

放射治疗的副作用可能包括轻度皮肤问题或疲劳.
