Winfrith - Transport Inspection

Executive summary

Purpose of intervention

Inutec Ltd has applied to ONR for a nuclear site licence for its undertakings on the Winfrith site. In order to determine whether to grant the requested licence, ONR is carrying out a series of interventions and assessments. This inspection forms part of this work.

Interventions Carried Out by ONR

During this intervention, ONR undertook compliance inspections against Licence Conditions 2 (LC2, Marking of the site boundary) and 25 (Operational records), and engagement regarding Inutec Ltd's emergency arrangements for the purposes of monitoring progress under two ongoing Regulatory Issues.

In addition, in response to a request from the Government's Business, Energy and Industrial Strategy Department (BEIS), we reviewed Inutec Ltd's means of controlling its nuclear inventory in accordance with criteria set in the Nuclear Installations (Prescribed Sites) Regulations 1983.

LC2 requires licensees to mark the boundaries of the site by fences or other appropriate means and to ensure these fences (etc) are properly maintained.

LC25 requires licensees to ensure that adequate records are made of the operation, inspection and maintenance of any plant which may affect safety and places further requirements on the types of record which must be made.

In this inspection, the site inspector and I walked the proposed site boundary, inspected items of Inutec Ltd documentation relevant to its licence request and held discussions with Inutec personnel, including discussions on the company'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.

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A - this was not a safety system inspection.

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

Inutec Ltd and the current Licensee, Magnox Ltd, demonstrated adequate means of marking the proposed nuclear site boundary. There are, however, some minor discrepancies between the proposed Inutec Ltd nuclear licensed site boundary and the map provided to ONR. These are attributable to drafting errors arising from quirks of the current licensed area. Granting of a licence to Inutec Ltd affords the opportunity to remove such quirks; it was agreed all parties would follow this matter up.

Inutec Ltd demonstrated adequate arrangements for control of its nuclear inventory for the purposes of ensuring its status as a Prescribed Site under the Nuclear Installations (Prescribed Sites) Regulations 1983.

Advice was provided to Inutec Ltd regarding its Emergency Plan which ONR intends to specify for approval, upon grant of a nuclear site licence. We noted however that, despite having a credible plan, Inutec Ltd was only able to demonstrate limited progress against the actions placed on it under Regulatory Issues 4947 and 5052.

Conclusion of Intervention

From the evidence gathered during this intervention, I noted no matters that impact significantly on nuclear safety. I awarded inspection ratings of Green (no formal action) against both LC2 and LC25. ONR will continue to regulate Regulatory Issues 4947 and 5052 to ensure required improvements to Winfrith's emergency arrangements are made in a timely manner.
