Key findings, inspector's opinions and reasons for judgement made

Based on the sample inspected, I judge that URENCO ChemPlants Ltd has appropriate arrangements for tracking nuclear material in QTM1 and QTM2 and that those arrangements are being adequately implemented in accordance with NSR19 Regulation 9 (1) requirement to implement and comply with the arrangements and procedures described in the accountancy and control plan and ONR regulatory expectations detailed in FSE 7 of ONMACS
From my sample I am content that URENCO ChemPlants Ltd are maintaining adequate operating and accounting records required by NSR19 Regulations 10 and 11 and that these records are traceable to and underpin the declarations within the accounting reports submitted to ONR in line with NSR19 Regulation 12.
From my review of arrangements for the production of nuclear material accounting reports I am content that URENCO ChemPlants Ltd has appropriate arrangements for data processing and control as detailed in FSE 8 of ONMACS
From my review of weigh scale calibration records and observed implementation of routine operational functional checks I judge the operator NMACS system is being implemented and maintained in accordance with ONR expectations for measurement and control of detailed in FSE 6 of ONMACS.
I provided regulatory advice relating to how the use of the locally developed arrangements are captured and linked to the formally issued operating instructions.


No matters requiring immediate regulatory attention were identified during this inspection.

On the basis of the evidence sampled at the time of the inspection, I judge that URENCO ChemPlants Ltd are adequately implementing arrangements for accountancy and control of QNM in line with regulatory expectations and are compliant with NSR19 Regulations 6,10 and 11. I also judge that URENCO ChemPlants Ltd are broadly meeting the expectations for measurement and control of QNM detailed in FSE 6, nuclear material tracking detailed in FSE 7 and Data Processing and Control detailed in FSE 8 of ONMACS. 

I judge that URENCO ChemPlants Ltd is complying with the requirements of NSR19 regulations 6, 10 and 11 and FSEs 6, 7 and 8. I did not identify any shortfalls and therefore judge that a rating of green (no formal enforcement) is appropriate.
