Future Trends in Nuclear Materials
A nuclear power plant is clearly a demanding proving ground of a maerial’s resilience. Materials possess a memory and damage is cumulative. Abuse early in life is rarely annealed out; even if it is, the accompanying microstructural changes are rarely acceptable for long lifetimes. Thus, for application in a hostile environment, and there is probably none more demanding than that of a nuclear reactor, materials must be fabricated with care, components must be constructed with care, and systems must be operated with care. These requirements place great demands on all concerned, from the forgemaster to the reactor operator. The reliability and safety record of the nuclear industry shows that this challenge is being met, but, with the increasing need to extract more energy from available systems, further improvements are called for.
