Frazer-Nash provides system process design at Hunterston B

Frazer NashFrazer-Nash has recently completed a contract with EDF Energy HNB Projects Department to provide the system process design for a new carbon dioxide (CO2) storage and delivery plant for Hunterston B nuclear power station.


The new plant will support the entire duration of the station’s working life extension and subsequent decommissioning, providing a supply of gaseous CO2 to the high pressure reactor ring main to meet all routine and safety case claims for the supply of CO2.


Frazer-Nash has worked closely with EDF Energy using a systems engineering approach to help deliver a CO2 plant system design, which provides enhanced nuclear safety, reliability, operability and maintainability when compared with the existing CO2 Plant.


The engineering consultancy has a long standing relationship of providing consultancy services to EDF Energy, but in a first for Frazer-Nash, the company has used its multidisciplinary capability to work with the project team at Hunterston B and EDF Energy Central Engineering at Barnwood to develop the design and produce the required technical documentation.


Frazer-Nash held a number of formal workshops with the EDF Energy project team and station operations and maintenance personnel, enabling it to define the user and system requirements and undertake system hazard and operability studies (HAZOP) and failure mode and effects analysis (FMEA).


John Collins, Frazer-Nash Technical Lead for the project said:“ The workshops were well received by the EDF team and provided a forum for enabling decision making and a rationale for fully understanding the initial concept and functional specification. As a result we were able to use our specialist expertise coupled with EDF’s domain knowledge to develop and substantiate a system process design that satisfied the nuclear safety requirements with improved performance, operability, maintainability and reliability.”


Frazer-Nash delivered this challenging project over a tight timescale with a team that drew together specialist expertise in a number of engineering disciplines including requirements management, design, process engineering, instrumentation and control, electrical engineering, safety, human factors assessment, pipe system performance assessment and reliability engineering to develop a fully engineered design solution.


Chris Jones, Business Manager at Frazer-Nash said “We have a strong pedigree in delivering across discipline engineering solutions for the nuclear industry and are delighted to have contributed to this significant contract directly with EDF Energy.”
