ABSTRACT
FPGA is a convenient technology that is being applied intensively to build I&CS for critical industries
like NPPs. Practical experience conirms that in some cases application of the FPGA technology is much
more reasonable than application of other technologies like microprocessors, etc. Experience of RPC
Radiy in FPGA-based I&C development is provided in this chapter, as well as general information on
FPGAs. Dependability of NPP I&CS is an important but challenging task. There are several techniques
that can be applied for safety and dependability assessments, but all of them have limitations and cannot
be easily applied in most cases. Sometimes combined usage of diferent methods is the most appropriate
solution. Techniques of dependability assessment and achievement developed and used by RPC Radiy,
as well as elements of the assessment methodology are briely described.
INTRODUCTION
accordance with international requirements on
nuclear and operational safety.
One of the contemporary trends is dynamically
growing application of novel complex electronic
components, particularly, FPGAs in NPP I&Cs and
other critical areas. I&C systems based on Field
programmable gate array (FPGA) technology
Nuclear power production is a safety-critical
process that requires reliable and safe operation.
Information & control systems (I&Cs) of nuclear
power plants (NPP) play key roles in stable opera-
tion ensuring and therefore should be designed in
