Description
The paper describes a fail-safe reactor protection system, called the individual sub-assembly temperature monitoring system (ISAT). It is being developed for the commercial demonstration fast reactor. The system incorporates recent advances in solid-state electronics and in particular microprocessors to implement time-shared data acquisition techniques to obtain and process data from around 1400 fast response thermocouples whilst meeting the required levels for reliability and availability.
