Validation of critical signals for the safety parameter display system: Final report

Technical Report ·
OSTI ID:6541428
Signal validation in the context of this project is the process of combining information from multiple plant sensors to produce highly reliable information about plant conditions. In this project, the signal validation methodology that has been developed in previous EPRI-sponsored projects has been enhanced and applied toward validation of critical safety related signals in the Northeast Utilities Millstone 3 Westinghouse PWR plant and the Millstone 2 Combustion Engineering PWR plant. The designs were implemented in FORTRAN software and tested off-line using recorded plant sensor data, RETRAN generated simulation data, and data to exercise software logic branches and test the integration of software modules. Designs and software modules have been developed for 15 variables required by 6 critical safety functions that have been selected as a shared SPDS requirement by a utility advisory group attached to the project.
