AWE compliance inspection

Executive summary

Purpose of intervention

The purpose of the intervention was to complete a system based inspection into site communications. This allowed ONR to review progress on a number of improvements AWE had identified in their Forward Action Plan (FAP) following the site PRS 5 years previously. The systems based inspection was planned in the weapons inspection plan.

Interventions Carried Out by ONR

I requested information in advance of meeting with the licensees personnel to discuss the site communications systems as part of a Systems Based Inspection which covers a number of licence conditions.

Explanation of Judgement if Safety System Not Judged to be Adequate

The System Based Inspection was judged to be adequate.

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

I discussed arrangements with the licensee's employees, observed some of the systems available and reviewed documents that support the availability of diverse communications for a range of scenarios. AWE were able to demonstrate they had identified how they would react in response to communications systems failures (individual or multiple) to ensure they could communicate across the site and with external stakeholders.

Conclusion of Intervention

I considered the arrangements AWE has put into place provide diverse means of communications and manage information to reduce the potential for overloading systems to be appropriate. The training provided on operation of new equipment was suitable. I judged AWE's arrangements to be appropriate and considered that no formal regulatory action was required in accordance with ONR's rating system.
