This report covers an inspection of Magnox Ltd’s Winfrith nuclear licensed site between 21st and 23rd September 2015. This inspection was undertaken as part of a programme of planned interventions as outlined in the IIS plan for 2015/16.
During this intervention, I carried out compliance inspections against the following licence conditions:
During this intervention, a specialist inspector and I assessed the Level 1 emergency exercise “Gannet”.
My inspections were carried out against the requirements of ONR's published inspection guidance associated with the above Licence Conditions. The inspection comprised office-based examination of procedures and records, interviews with staff and work place inspections.
This intervention did not include an inspection of a safety system.
In relation to Licence Condition 4, Restrictions on Nuclear Matter on the Site, I considered that the licensee had made and implemented suitable arrangements for the importation of radioactive materials to site that ensure that that a suitable safety case exists for the facility that will receive the radioactive materials. I have also sampled the licensee’s arrangements for the receipt of radioactive materials onto site and am satisfied that these are being properly implemented.
In relation to Licence Condition 5, Consignment of Nuclear Matter I have found that the licensee has comprehensive arrangements for the consignment of radioactive materials from site. I sampled the licensee’s arrangements for the despatch of radioactive materials from the site and I am satisfied that these are being properly implemented.
In relation to emergency exercise “Gannet”, I considered that the planning for this exercise was thorough, and that the scenario was proportionate to the hazards remaining on site whilst remaining challenging of the emergency arrangements. During its observations of the emergency exercise, a number of good points and areas for improvement were identified.
Taking into account the exercise planning/ scenario and all the ONR team’s exercise observations I consider the emergency exercise to be an adequate demonstration of the site’s emergency arrangements.
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.
