Reliability assessment of diversity in digital I&C systems at nuclear power plants
Original language description
Digital automation devices start to be widely used within safety critical Instrumentation and Control systems at NPPs. This modern technology by itself is obviously relatively highly reliable and also brings side advantages which make the status of control devices more transparent and modifiable. The main safety concern is a possibility of an occurrence of dependent failures, which could leads to the loss of several safety functions. The diversity is a very important principle in the effort to avoid Common Cause Failures. Probabilistic reliability assessment of different ways of diversity in complex digital systems seems to be a good way how to disclose potential shortages of particular diversity approaches. Experience with probabilistic approach in digital I&C evaluation nevertheless shows a lot of uncertainty in results which mainly origin in insufficient knowledge of the behavior of both the electronic devices and software in particular. The experimental model based on a Fault Tree
