Preventive maintenance (PM) programs in US nuclear plants have evolved from strict compliance with the vendor`s general recommendations which are likely to be conservative, to more flexible tasks which are intended to accommodate the plant service conditions. These PM programs have evolved piecemeal from the vendor recommendations and historical experience, with the result that their logical structure and coherent basis may be technically weak and scarcely recognized. The historical reasons for the performance of specific PM tasks are usually poorly documented, if at all. The result is that relationships and dependencies between the tasks, their limits of applicability and justifications for task intervals, are not well known. Utilities have expressed the desire for a technical basis and rationale capable of supporting the maintenance tasks for each major component type and of facilitating appropriate changes to them. The PM Basis project provides the utility user with the technical basis for PM tasks and task intervals and also gives the necessary information to adapt the tasks and intervals to plant conditions. A recommended program of PM tasks, a synopsis of the task content and intervals, and the reasons why these choices are technically valid in a variety of circumstances, are presented for 39 major component types. Each component type is treated in a separate volume of this series. This project overview report presents the project objectives and organization, describes the content, interpretation, and use of the PM Basis database, and explains the process by which the information was obtained.
