Imperial College Reactor Centre (ICRC) - ICOL LC 21 Active Commissioning Readiness Inspection

Executive summary

Purpose of intervention

This is a planned readiness inspection at Imperial College (ICOL) undertaken as part of the planned integrated intervention strategy (IIS) for ONR's Decommissioning Fuel and Waste Programme.

Interventions Carried Out by ONR

This was a planned inspection covering:

The licence condition was inspected against ONR's published guidance requirements (as described in ONR's technical inspection guides).

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable

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

I found ICOL's LC 9, 10, 12, 21, 26 and 36 arrangements, to enable the move from inactive to active commissioning, to be adequate (Rating 3 - Adequate).

The inactive commissioning of the CONSORT research reactor defueling equipment was considered to be nearing completion. ICOL was judged to have adequate LC 21 arrangements in place to proceed to active commissioning.

Whilst a number of minor regulatory observations were identified, ICOL has committed to addressing these through its internal governance process. ICOL has confirmed that these observations will be closed before the start of active commissioning. Given this commitment, I judge that it would be disproportionate not to provide a regulatory statement of no objection to allow active commissioning to proceed.

A number of minor issues relating to the comprehensiveness of documentation, and ICRC's organisational capability moving into decommissioning, will be addressed during ongoing regulation after the defuelling project is complete.

From the information gathered during this inspection, ONR and the Environment Agency found no evidence that would prevent the CONSORT research reactor moving from inactive to active commissioning of the defueling equipment. Consequently, I recommend that ONR provides ICOL with a statement of 'no objection' to proceed towards active commissioning.

Conclusion of Intervention

ICOL's LC 9, 10, 12, 21, 26 and 36 arrangements were judged to be adequate. I recommend that ONR provides a statement of no objection, for the CONSORT research reactor, to proceed to active commissioning of the defueling equipment.
