The people in our business are recognised internationally for their professionalism and range of capabilities.  To support our nuclear work our project teams include specialist engineers and designers as well as nuclear and industrial safety experts.

Our projects are supported by colleagues throughout Halcrow, including contaminated land specialists, environmentalists and geotechnical engineers.

Whatever the project and wherever the location we ensure that our project teams include the relevant safety and environmental specialists.

Safety and Environment Support - Halcrow’s depth of experience and engineering and environmental knowledge, positions the company to provide world class integrated safety and environmental support.  Many of our specialists are renowned in the work they do in environmental and safety case management.

Safety Case Production:  Halcrow’s nuclear safety team are experienced safety consultants with a track record of managing, preparing, implementing and reviewing safety documentation.  This experience includes safety documentation production for new and existing facilities, decommissioning safety cases, modifications to systems / facilities.  It extends from concept stage preliminary safety reports to detailed design pre-construction safety reports and eventual pre-operational safety reports.

Hazard Identification Tools: Halcrow’s nuclear safety team is experienced in the use of an extensive number of risk identification techniques.  These are targeted to ensure our clients receive maximum value from the chosen technique and can vary from methodical / systematic HAZOP technique to the more imaginative use of brainstorming processes.  Our senior safety engineers are experienced in the use of Structures “What-If” Techniques (SWIFT) and several other hazard identification tools, ensuring the identification of the maximum number of pertinent hazards.

Hazard Assessment Tools:  Our specialists undertake complex hazard assessment, to support safety documentation production.  These include quantitative and qualitative techniques such as FMEA, FMECA, fault tree analysis, event tree analysis, radiological HAZAN production including radiological dose modelling and human factors/violation assessments.  Our safety engineers have experience of risk assessment covering both risk to operators and members of the public.  They are also commercially experienced in assessing business risks as a result of business critical system failure, resulting in loss of production, damage to company image etc.

Case study - Dounreay - D1209 ventilation and gaseous discharge service

Between 2004 and 2006 Halcrow undertook the design of the complex D1209 gaseous discharge upgrade project.  As part of this commission Halcrow was responsible for the detailed design, environmental and safety documentation production.  This involved the development of the Best Practical Means (BPM) report and discharge modelling. This determined optimum stack height and discharge characteristics to minimise, as far as reasonably practicable, the dose to the critical group.  Halcrow was also responsible for the production and management of the Pre-Construction Safety Report (PCSR) for the project.  This involved integrating the safety case team into the design process and developing Safety Functional Requirements, which the design could then be developed against.  The design was substantiated by our engineers and this fed into the safety case to justify the overall safety of the proposed modification.  The project was delivered on time, to budget and quality.

Case study - Drigg Post-Closure Safety Case

Between 2000 and 2003 Halcrow provided support to BNFL in the preparation of the Drigg Post-closure Safety Case (PCSC). This support included the provision of advice on aspects of the direction and development of the safety case as well as the production of documentation. The work of these committees included the development of Drigg specific FEP lists that identified all Features, Events and Processes (FEPs) that could impact on the performance (in broadest terms) of the facility.

Case study - Hunterston A Temporary Weather Barrier Safety Case

Halcrow’s safety team are currently involved in the management and production of an options study review and safety case (Pre Commencement Safety Report) for the Hunterston A Reactor Buildings Temporary Weather Barrier project.  The commission involves the production of an options study to consider additional options which could be investigated to remove the potential hazard associated with the glazing system on the reactor buildings.  This study was followed by the development of a PCSR to allow the project to progress to the installation phase.  The PCSR production involved the identification, assessment and consideration of hazards associated with the project.  This project represents one of the early stages of an eventual strategy to place the reactor buildings into safe store through the construction of a Weather Envelope, a project on which Halcrow are providing Design and Safety case services.
