Key findings, inspector's opinions and reasons for judgement made
This inspection focused on seeking regulatory confidence that the operator is maintaining an appropriate system of accountancy and control of qualifying nuclear material that includes suitable arrangements for material balance evaluation. This was achieved by reviewing an appropriate sample of operating instructions and arrangements followed by discussion with staff with operational implementation responsibilities within targeted facilities.
Based on the inspection activities sampled I judge that Urenco Chem Plants Ltd are maintaining an appropriate system of accountancy and control of qualifying nuclear material broadly in line with the requirements of NSR19 Regulation 6 and are adequately implementing those arrangements in line with our regulatory expectations detailed in FSE 9 (MACE 9.3) of ONMACS and rated the inspection GREEN.
I identified several areas of good practice.
Conclusion
No matters requiring immediate regulatory attention were identified during this inspection.
Based on the inspection activities sampled I judge that Urenco Chem Plants Ltd are maintaining an appropriate system of accountancy and control of qualifying nuclear material that includes suitable arrangements for material balance evaluation broadly in line with the requirements of NSR19 Regulation 6.
I also judge that Urenco Chem Plants Ltd are adequately implementing those arrangements in line with ONR regulatory expectations detailed in FSE 9 (MACE 9.3) of ONMACS.
