The reliability of plant control and protection is strongly dependent on the reliability of the plant instrumentation system. The experience from the operation of nuclear power plants has shown that erroneous and contradictory instrument signals confuse the operator and delay corrective action. The same experience has also shown that about 10% of the total unplanned shutdowns are due to instrument failures. Plant safety as well as plant availability can be enhanced by improving the reliability of instrument information. A methodology has been deveoped that provides validation of safety-significant plant parameter measurements, plant state verification, and fault identification in the presence of many instrumentation failures (including multiple common-cause failures). This paper presents the basic features of this methodology and some results of its application to a reference LMFBR plant.
