This report covers an inspection of Magnox Ltd's Harwell nuclear licensed site between 18-20 January 2017. This inspection was undertaken as part of a programme of planned interventions as outlined in the IIS plan for 2016/17.
During this intervention, ONR inspectors carried out compliance inspections against the following licence conditions:
Whilst on site I held meetings with the licensee to discuss a number of routine matters.
My inspections were carried out against the requirements of ONR's published inspection guidance associated with the above Licence Conditions. The inspection comprised plant inspection, office-based examination of procedures and records and interviews with staff.
No safety system was inspected during this intervention
In regard to LC22, I have inspected the implantation of the licensee’s arrangements for the modification of existing plant by sampling the production of a preliminary safety report. I consider that the licensee has identified the appropriate need for safety related equipment and judge that the licensee has also demonstrated that it is working to its own arrangements.
In regard to LC26, I have inspected the licensee’s arrangements for the control and supervision of operations by concentrating on the appointments of Authority to Operate Holder and Duly Authorise Person for the B462 complex. Whilst I consider that the licensee has appropriate arrangements for supervision of operations for now, I have challenged the licensee to review its proposed organisational structure to ensure there is sufficient separation between operations and compliance.
In relation to LC 35 Decommissioning, I considered the licensee’s decommissioning strategy and programme. I noted that the licensee is currently reviewing its arrangements to ensure that they are adequate for future work it was planning. I consider that the licensee had demonstrated that it has implemented its decommissioning arrangements adequately.
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
From the evidence gathered during this intervention, I conclude that there are no matters that may impact significantly on nuclear safety.
