The Grove Centre, Amersham - Operational Standards Inspection

Executive summary

Purpose of Intervention

In accordance with the DFW strategy, a planned Operational Standards Inspection (OSI) on the Drytec Generator Facility and the Materials Handling Centre was undertaken at the GE Healthcare Ltd licensed nuclear site at the Grove Centre, Amersham.

The intent of an OSI is to consider key human related Licence Conditions, Leadership and Management for Safety and ONR Safety Assessment Principles (SAPs) in an integrated way, drawing on consideration of the leadership and safety culture within the facility whilst focusing on front-line activities. During this inspection, I sought to gain evidence that within the facility:

The leaders and managers responsible for operations had adequate ownership of operational and behavioural standards and have arrangements to monitor performance against them (LC17, SAPs MS.1 and SAPs MS.3).

There was a learning and performance improvement culture and adequate supporting arrangements (LC7, LC25 and SAPs MS.4).

The organisational structure (LC 36) and operational capability (SAPs MS.2) are adequate.

Operational practices are linked to the conditions and limits identified in the safety case (LC23); they written into the operating instructions (LC24); there was adequate supervision and control of work (LC26) and that persons conducting operations were adequately trained and authorised to do so (LC10 and LC12).

Interventions Carried Out by ONR

I carried out an on-site Operational Standards Inspection covering a suite of Licence Conditions.  The inspection comprised of presentations and discussions with GE Healthcare Ltd staff, plant walk downs and reviews of plant records and GE Healthcare Ltd arrangements.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not Applicable.

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

From the areas examined, I did not identify any significant shortfalls in the licensee’s compliance with their formal arrangements for LC’s 7, 10, 12, 17, 23, 24, 26 or 36, which merited any formal action.

Conclusion of Intervention

This intervention provided ONR with a comprehensive view of the operational standards and the supporting management arrangements of the GE Healthcare Ltd site at Amersham.  Overall I was satisfied that the evidence provided during the inspection demonstrated good alignment with these arrangements and a positive safety culture. I made a small number of minor observations, and gave regulatory advice to the licensee to address these.
