Sizewell A system based inspection on SVSAVD system

Executive summary

Purpose of Intervention

This inspection was undertaken as part of a planned programme of inspections for 2017/18 at Magnox Ltd.'s Sizewell A licensed nuclear site.

Interventions Carried Out by ONR

During this intervention, I undertook:-

Explanation of Judgement if Safety System Not Judged to be Adequate

The FED retrieval system satisfies the requirements of the safety case.

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

Sizewell site is managing a significant increase in workload across a number of different work-streams and is taking due regard to safety.

The FED Retrievals project is about to commence detailed design, this project builds on the knowledge and experience gained with previous FED retrieval projects at other sites whilst is taking care to maintain a proportionate approach to the specific needs of the site.

I also undertook a site walk-down and a meeting with the safety representatives. The safety representatives raised a number of issues that were being progressed through due process. I did not need to formally intervene in the interests of safety.

I reviewed the arrangements for Sizewell's preparations to take on remote management of the Bradwell site. The organisation of the remote management team has been strengthened to provide more focussed direction of the work. The training burden has also been focussed onto providing a core of trained staff in time for the entry to C&M. SZA staff are also participating in the Resources Management Group to ensure that staff who could assist with the handover are not released from Bradwell too early.

I attended the Sizewell SSG meeting and referred to my SSG report. Questions were asked relating to the transfer of ILW to the Bradwell ISF, the potential for contamination from Russian Ruthenium 106 releases and the pollution from Sellafield. I responded as best I could as these matters are not in my normal work area and my responses were supported by the chair.

Conclusion of Intervention

From the evidence gathered during this inspection, I concluded that there are no matters of nuclear safety concern. No regulatory issues were raised.
