ENGINEERING SUBSTANTIATION SUPPORT FOR CULHAM KEY SAFETY RELATED EQUIPMENT

Client:
UKAEA, Culham

Description:
UKAEA identified a requirement to carry out an engineering substantiation study of the Key Safety Related Equipment (KSRE) prior to the start of the Trace Tritium Experiments (TTE) that were to be carried out during September – October 2003. The aim was to identify the key safety requirements within the Torus and AGHS POSR, advise engineers carrying out the assessment and pull together the results and any recommended changes to the equipment in time for them to be implemented prior to the start of TTE and advise on proposed implementation changes to the KSRE. Due to the age of the equipment it was not possible to carry out a full engineering substantiation study in line with the UKAEA/SAH/G3 procedure so a simpler Fitness for Purpose (FFP) study was carried out and reported to the Culham Safety Committee.

Scope of service supplied

• Identify the Safety requirements from within the Torus and AGHS Pre-operational Safety Report

• Identify the requirements for the UKAEA/SAH/G3

• Develop success criteria for each KRSE

• Review UKAEA’s implementation of the BS IEC 61508 on Safety Integrity Levels and its application to the JET’s FFP studies and provide advice to engineers carrying out the FFP studies

• Assess safety case modifications where required

• Peer Review the FFP study reports

• Prepare the summary document for the Chief Engineer to present to the Culham Safety Committee for all the FFP studies
