Safety Assessment Handbook, Urenco
Urenco operates uranium enrichment facilities that increase the concentration of fissile isotope U-235 as part of the production of fuel for nuclear power reactors. The facilities date from the 1980s onwards and regulation requires periodical review of their condition, engineering and operational standards. RPS was contracted to revise the company’s guidance on the development of safety justifications.

Challenge
Urenco identified that the facility safety cases needed to be revised as their initial development had revealed some implementation issues with the existing Safety Assessment Handbook (SAH) and there had been significant developments in regulatory objectives since it was written.
Urenco undertook a structured review of these issues and requirements. The challenge was therefore to revise the guidance to facilitate the development of proportionate safety assessments that did not result in unmanageable requirements in plant operation.
The SAH revision needed to:
- Ensure proportionate safety measures and engineering requirements.
- Balance the management of chemical and radiological hazards.
- Provide flexibility to the safety assessors and engineers.
