The main objective of this paper is to establish the essential information that is needed so that an adequate engineering and probabilistic assessment of the Reactor Protection System (RPS) can be carried out. This required information takes the form of questions that the assessor needs to ask of the system to aid his analysis. The SCRAM function of the RPS is used as an example. For simplicity and ease the RPS is divided up into its three main functional subsystems namely: 1) The Parameters, Permissives and Interlocks; 2) The Safety Logic; 3) The Relay Actuation and Control Rod Actuation. This paper includes questions related to the above listed subsystems, and satisfactory answers should be obtained from the Plant Safety Analysis Report, Plant Scpeificiations and Analyses. Conclusions reached should indicate that information is adequate to: a) demonstrate design intent; b) demonstrate how the system functions; and c) undertake a meaningful engineering and probabilistic assessment.
