Abstract
Digital instrumentation and control systems (I&C) are
appearing as upgrades in older nuclear power plants
(NPPs) and are commonplace in new NPPs. To assess the
risk of NPP operation and to determine the risk impact of
digital system upgrades on NPPs, quantifiable reliability
models are needed along with data for digital systems
that are suitable for using in existing probabilistic
safety assessments (PSA). This paper presents a
methodology for the consideration of software failures of
I&C systems in nuclear PSA context. Evidence of
operational data of the digital system platform TELEPERMr
XS (TXS) developed at AREVA GmbH is considered in the
software failure probability quantification process.
