Remote Multiplexing System Application to a Nuclear Generating Station - An Update

A previous paper (1) gave a preliminary description of a Remote Multiplexing System (RMS) for the Washington Public Power Supply System´s Nuclear Project No. 2 in its initial design stage. This paper describes the final design including Class IE qualification requirements and testing. It is believed that this is the first time a RMS design has been used in Class IE systems and for such extensive control and data gathering applications to achieve substantial economy and flexability in a nuclear power generating station. It is hoped that valuable experience will be obtained from this installation and will pave the way for further RMS applications.
