The paper presents a general analytical framework to analyze unavailability caused by latent failures in standby safety systems used in nuclear plants. The proposed approach is general in a sense that it encompasses a variety of inspection and maintenance policies and relaxes restrictive assumptions regarding the distributions of time to failure (or aging) and duration of repair. A key result of the paper is a general integral equation for point unavailability, which can be tailored to any specific maintenance policy. (authors)
