- Additional information
- The output was supported by funding from CINIF (UK Control and Instrumentation Nuclear Industry Forum), part of research to support validation of existing and future reactor safety cases. The diverse 1-out-of-2 architectures modelled are fundamental in the industry, but hard to assess. The presented work demonstrates a mathematical structure for this assessment, combining previously developed methods with novel solutions. NASA/CR–2018-220080 technical report, "Considerations in Assuring Safety of Increasingly Autonomous Systems" points to this work as one way of managing epistemic uncertainty.
