Announcing the third speaker at CRA’s annual Risk Forum 5th & 6th October 2016.
Speaker: Hugh Stephenson, Principal Consultant at CRA
Topic: ‘Computer Says No’ – Safety and Security Challenges with Digital Control Systems
Interesting Fact Hugh’s degree is in Automotive Systems Engineering Design. He maintains a series of old cars and is a Nuclear Biker.
An increasing amount of digital Control and Instrumentation is being used in automation at existing and planned Nuclear Power Plants. Whilst the operational benefits are large, this increase presents a range of new challenges in the areas of both nuclear safety and security. In this session, some of these challenges will be examined further, in particular the estimation of reliability of equipment for use in both probabilistic and deterministic safety cases, drawing comparisons with the equivalent reliability of analogue and manual alternatives.
The increased use of digital technology also requires careful consideration of associated security risks. This session will close with a brief introduction of such issues and their potential impact on nuclear safety risk, drawing on lessons learned from the Stuxnet events of the 21st century.
