Announcing a further speaker at CRA’s annual Risk Forum on 5th & 6th October 2016 in Stratford upon Avon.
Speakers: Bryan Coxson from EDF Energy
Topic: Designing for Safety trumps Operability: A Case Study at Sizewell B
Bryan Coxson’s talk will cover a period of over 35 years and focus on some specific features of the Sizewell B design relating to Instrument Air Systems. In 1995, these features assisted in enabling Sizewell B to be the only ‘off the drawing board’ design classed by the US Electric Power Research Institute (EPRI) as an ’Advanced PWR’.
The talk will cover how these features have been modified in the light of Operational Experience, the Sizewell B Living PSA, and current HRA techniques. The final outcome – 35 years on – was the automating of a claimed operator action following a plant modification completed during a recent outage at the station.
Bryan Coxson (C Eng MIET) started his career working on reliability aspects of distribution, transmission, and power generation in the Electricity Supply Industry. In 1986 he joined the Sizewell B design team introducing PWR technology to the UK. Bryan was in the licencing Safety Case team, responsible for procuring the operational, equipment failure and human error data. He currently works in the Design Authority for EDF Energy Generation as a Safety Case engineer supporting the Sizewell B Living PSA. Despite working in the industry for over 45 years, he still enjoys ferreting out insights that otherwise might be overlooked.
