Introduction

Redundant Sensor Algorithms (RSAs) are utilized to eliminate single point of failure vulnerabilities within the control application and improve reliability and robustness of the system and its ability to automatically control the plant over its full power range for the entire fuel cycle. These allow the system to suffer a partial or complete loss of one of the redundant input signals with minimal or no upset to plant operation or loss of vital plant process information. The redundancy starts at the process measurement transmitters. Multiple, mutually exclusive field devices are used to measure the same plant process variable. These measurements are brought into the control system on separate I/O devices (FBMs), further increasing the reliability of these signals. Care is taken to also ensure that the transmitters are on separate process connections, otherwise they are still vulnerable to a single failure, such as plugged piping or failure of the sensing line piping itself.

For all cases, when there is ‘No Valid Input.’

Control “action” is blocked

Failsafe action is imposed

Controls are transferred to MANUAL where applicable, holding the plant at a known state.
