GE Healthcare Grove Centre Nuclear Licenced Site, Amersham Planned Inspection of LCs 19, 21 and 22

Executive summary

Purpose of intervention

This was a planned intervention at the GE Healthcare Grove Centre Nuclear Licenced Site in Amersham to inspect licensee compliance with Licence Conditions 19 (Construction or Installation of New Plant), 21 (Commissioning) and 22 (Modification or Experiment on Existing Plant) as part of a planned intervention within the Decommissioning Fuel and Waste plan.

Interventions Carried Out by ONR

I visited the site on the 15th and 16th December 2015 and met with the Safety Case Manager, Project Managers, Safety Case Author, Engineering Design, Project Lead and Project Manager.  The intervention involved sampling the licensee’s arrangements and implementation to assess compliance with Licence Conditions (LC) 19, 21 and 22.  I also inspected some plant areas where new plant had been installed and where modifications had been implemented.

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 19 (Construction or Installation of New Plant), 21 (Commissioning), and 22 (Modification or Experiment on Existing Plant).

The arrangements for LC19 were appropriate and their implementation for a package of work showed clear oversight and control.  I judged this demonstrated adequate compliance with the LC19 requirements.

The procedures for commissioning (LC21) were sampled as were records which clearly showed the testing that had been completed and ‘as built’ records that were produced.  There was clarity on when commissioning started and the authority required to progress into the operational phase.  I considered these arrangements to be adequate for compliance with LC21.

The arrangements for the control of modifications were inspected and examples of the documentation prepared to assess and control these modifications were sampled.  Plant locations where modifications were on-going or completed were inspected.  I consider there are appropriate arrangements in place to identify and assess modifications and to provide suitable controls to ensure the impact on safety is addressed.  The implementation of the modifications was also sampled and found to be satisfactory.  I judged a rating of 3 (adequate) was appropriate against LC22.

Conclusion of Intervention

I judged that the licensee’s arrangements for compliance with LCs 19, 21 and 22 were adequate.
