Imperial College Nuclear Licensed Site Ascot Planned Inspection of LCs 4, 5, 7 and 14

Executive summary

Purpose of intervention

This was a planned intervention at the Imperial College Nuclear Licenced Site in Ascot to inspect licensee compliance with Licence Conditions 4 (Restrictions on Nuclear Matter on Site), 5 (Consignment of Nuclear Matter), 7 (Incidents on the site) and 14 (Safety Documentation) as part of a planned intervention within the Decommissioning Fuel and Waste plan.

Interventions Carried Out by ONR

I visited the site on the 26th and 27th November 2015 and met with the Head of the Reactor Centre and the Safety, Assurance and Emergency Planning Manager.  The intervention involved sampling the licensee’s arrangements and implementation to assess compliance with Licence Conditions (LC) 4, 5, 7 and 14.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not Applicable.

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

I sampled the licensee’s arrangements for compliance with Licence Conditions 4 (Restrictions on Nuclear Matter on Site), 5 (Consignment of Nuclear Matter), 7 (Incidents on the site) and 14 (Safety Documentation).

Imperial College has arrangements for LC4 which are currently being reviewed.  I inspected the storage and management of radioactive materials to judge whether they are being held safely.  I consider that the radioactive materials I inspected were stored safely but I identified some areas for improvement which the licensee agreed to implement.  The improvements I identified and the absence of up to date procedures justifies an intervention rating of 4, below standard.

Whilst the arrangements for LC5 are in need of updating to reflect current Transport Regulations, they are overly restrictive as they prevent them from sending non-waste items to other licensed sites even though the Licence Condition permits this.  However, this would only apply to a small number of items if they consider them not to be waste and I judged the arrangements to be adequate for the current operations on the site.

The arrangements for LC7 aim to capture all unusual occurrences, including the more significant incidents.  These are investigated and actions are placed to prevent a recurrence.  Given this is a small licenced site with a very small number of incidents, I judged the arrangements to be adequate.

I sampled the licensee’s arrangements for compliance with LC 14 and judged that the processes to identify hazards and produce the safety case (including the categorisation and review processes) were adequate.

Conclusion of Intervention

I judged that whilst the licensee’s arrangements for compliance with LCs 5, 7 and 14 were adequate, their arrangements for LCs 4 were in need of improvement and so were below standard.
