This inspection was undertaken as part of a planned programme of inspections for 2018/19 at Magnox Ltd.’s Sizewell A licensed nuclear site.
During this visit, I undertook a System Based Inspection (SBI) on the preparations for the Grid Building Demolition Project. The inspection was carried out against the requirements of LC’s 10, 23, 24 27, 28 and 34.
I also undertook a general site walk-down, including a visit to the Cooling Water Pump-house.
I sought information on progress with the decommissioning of the ponds and the FED retrievals plant and aspects of the remote management of the Bradwell site.
I participated in a conventional health and safety inspection targeted at work to remove asbestos contaminated materials from the site.
I examined a sample of the Site’s management arrangements for handling nuclear matter and for managing operations on the site. There is a clear management structure and process. An established and effective process for managing the project work for the demolition of the structure is in place. Therefore, I rated compliance with LC’s 10, 23, 24, 27, 28 and 34 as adequate.
The plant and equipment in the cooling water pump-house has been removed and the area is now redundant. It would be a suitable place to dispose of rubble left from the demolition of the remaining facilities.
From the evidence gathered during this inspection, in respect of the demolition of the grid building, I concluded that the arrangements are adequate and no matters of significant nuclear safety concern were identified.
Magnox Ltd should give consideration to re-purposing the cooling water pump house as a repository for rubble currently stored above ground when other facilities are demolished.
