Since one requirement for the qualification of safety-related components for the nuclear power industry is that consideration be given to aging of the component prior to any tests in a simulated accident environment, there is considerable interest in accelerated aging techniques. One of the more difficult areas of accelerated aging occurs in simulating the ambient deterioration of a component which degrades due to a combination of two or more environmental stresses. Inside the containment of a nuclear power plant many components exist in combined radiation, thermal, and humidity environments. In such situations, the deteriorating effects of the various environments may not be additive; in other words synergism is potentially important. This can greatly complicate accelerated aging. The results of a continuing program whose main goal is the development of reliable accelerated aging techniques are described. One result of these studies was the development of an approach or method potentially applicable to combined environment aging when synergism is important. A brief review of this suggested approach is given, followed by an extensive discussion of aging data on a neoprene cable jacketing material.
