A methodology has been developed that provides validation of safety-significant plant parameter measurements, plant state verification, and fault identification in the presence of many instrumentation failures, including common-cause failures. This methodology is based on a systematic search for a ''minimum system validation set'' and plant computer models that run in real time. A minimum system validation set is defined as a set that contains a minimum number of parameters sufficient to define the system state (minimum system state definition set) plus one more parameter whose value can be analytically generated from the minimum system state definition set. This methodology is presented using a liquid-metal fast breeder reactor plant as a reference. All the minimum system validation sets, the associated instrumentation failures, and the sets of instrumentation failures that do not allow plant state verification are determined for this plant.
