Mitsubishi PLC in nuclear power plant

Does anyone knows what type of Mitsubishi PLC is used in reactor protection system in nuclear power plant?

I for one hope it is a safety PLC.

Why ?

Mitsubishi Nuclear Power System got a couple of contracts in US, I assume Mitsubishi control system (PLC, DCS) is used for those projects, interest to know what type of PLC is used, of course, it has to be safety class PLC.

It is probably a DCS type control system.
And I believe that it must have triple redundancy for the parts of the system that are critically important for monitoring and safe shutdown. The PLCs systems with redundancy that I know of, have only regular redundancy.

Just a tid-bit of information, GE actually has "Quad" redundancy available with theri Rx7i series of processors.
