Pre Licensing Compliance Inspection

Executive summary

Purpose of intervention

Tradebe Inutec Ltd has applied to ONR for a Nuclear Site Licence for its undertakings on the Winfrith site. In order to determine this application, ONR is working to an inspection and assessment plan. This report covers an inspection at Tradebe Inutec Ltd's facility on 31 August 2016. This inspection will be used to inform ONR's decision whether to grant a nuclear site licence to Tradebe Inutec Ltd.

Interventions Carried Out by ONR

During this intervention, ONR inspectors examined Tradebe Inutec Ltd's proposed arrangements for the following licence conditions to enable judgement as to the adequacy of those arrangements to meet ONR's requirements:

Whilst on site I held meetings with the licensee to discuss and follow up on the status of actions and held meetings 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.

Explanation of Judgement if Safety System Not Judged to be Adequate

No safety system was inspected during this intervention.

Key Findings, Inspector's Opinions and Reasons for Judgements Made

In regard to Licence Condition 14, this inspection has compared Tradebe Inutec Ltd's arrangements for the production and maintenance of its safety case with the relevant ONR Technical Inspection Guide. This inspection identified some improvements that Tradebe Inutec Ltd has accepted. I have concluded that Tradebe Inutec Ltd has developed adequate arrangements that would meet ONR's requirements for the production and maintenance of safety cases.

In regard to Licence Condition 15, the inspection found that Tradebe Inutec Ltd need to make improvements to its arrangements for the periodic review of its safety case. Tradebe Inutec Ltd has recognised that it needs to ensure that it makes clear arrangements for periodic review and will supply ONR with an action plan for production and implementation of suitable arrangements to undertake periodic reviews. As a consequence of this finding an ONR issue has been raised to record progress towards completing this action.

In regard to Licence Condition 23, it was found that Tradebe Inutec Ltd has an adequate safety case which identifies the limits and conditions necessary in the interests of safety, which are in turn clearly translated in to its working procedures. Tradebe Inutec Ltd's arrangements are suitable to ensure that operations are at all times carried out in compliance with such limits and conditions, and that arrangements for notifying, recording, investigating and reporting any breaches are sufficient.

In regard to Licence Condition 24, it was found that Tradebe Inutec Ltd has suitable arrangements to produce written operating instructions. The instructions that were sampled were found to be clearly written and capable of being understood by a suitably qualified and experienced person. Tradebe Inutec Ltd was judged to have a suitable process to review and amend its instructions.

In regard to Licence Condition 28, this inspection found that Tradebe Inutec Ltd has suitable arrangements for regular and systematic examination, inspection, maintenance and testing of all plant which may affect safety. All such plant is identified on the maintenance schedule derived from the safety case, and Tradebe Inutec Ltd suitably demonstrated the implementation of its arrangements through sampling of the maintenance records database. During this inspection we have identified some improvements that Tradebe Inutec Ltd has accepted.

The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.

Conclusion of Intervention

From the evidence gathered during this intervention, I conclude that there are no matters that may impact significantly on nuclear safety.
