- Contract research for the UK Control and Instrumentation Nuclear Industry Forum (CINIF) on the reliability of diverse protection "trains" in critical systems. The diverse trains cannot be generally proved to fail independently; the question is how much improvement can be claimed over a single train. This output shows how to obtain a conservative bound for the improvement.
The method has been applied to a nuclear plant case study (CINIF report PB_DISPO2_03), and the same concept has proved useful in other conservative bounding methods for safety assessment (see https://openaccess.city.ac.uk/id/eprint/15248/ and https://openaccess.city.ac.uk/id/eprint/24378/)
