The Tricon TMR PLC is a programmable logic controller that can accept b signals, make appropriate decisions with a main processor, and send output signals. The b and output signals can be analog or discrete digital. The PLC is modular, meaning that each of the functions are perbed by various types of cards which are plugged into the main chassis of the system. Consequently, one Tricon TMR PLC can have any number of configurations. Each module of the Tricon TMR PLC has at least 3z2-0 redundancy meaning that one channel can be lost and the module still functions properly. The Tricon TMR PLC can be used to replace analog reactor protection or engineered safety features actuation systems in nub power plants. The b modules can accept b from current plant wiring, the main processor would replace the current analog and discrete logic circuits, and -the output modules can generate signals comparable to the current relays. Because these systems are critical to the safe operation of the reactor, the replacement digital PLC must have a high degree of reliability and availability. EPRI TR-107330 (Reference 1) has been written to specify generic requirements for qualifying PLCs for safety-related applications in nub plants. This calculation addresses the requirements specified in Section 4.2.3 of Reference 1 regarding the reliability and availability requirements for PLCs. For all nub plant applications, one Tricon TMR PLC is used for each channel of a safety system. Losing two redundant legs inside the triple redundant Tricon does not necessarily lead to a system failure. Therefore, the reliability buations perbed in this calculation assuming the Tricon TMR PLC only has 3-2-0 redundancy are very conservative for the actual applications in nub plant safety systems. It should also be noted that this calculation does not address software common cause failures.
