Abstract
Software-based safety systems have become increasingly
common in nuclear power plants. Due to their complexity,
software applications can almost never be exhaustively
tested and proved error-free. FPGA technology could
alleviate these problems with the less complex hardware
and flexible capabilities of software. As FPGA technology
is rather new in the nuclear industry, there are
currently no commonly accepted regulations or guidance
directly addressing the use of FPGAs in NPPs. This paper
presents how we implement two variants of an I&C safety
system called Stepwise Shutdown System using FPGA
technology. One of the variants contains a design error,
and the other is free of errors. We demonstrate how the
nuclear domain I&C systems can be designed using this
technology, and show how the design error in the I&C
design was found using simulation and hardware tests.
