The purpose of this routine intervention was to inspect the adequacy of the implementation of the site's LC26 (Control and Supervision of Operations) arrangements on a waste & decommissioning project.
The project, which is nearing completion, has involved the demolishing of several decommissioned waste treatment facilities and the sentencing of waste materials arising from these operations, some of which are radioactively contaminated, into appropriate categories for safe management and disposal as appropriate. The operations have been carried out largely by contractors under the control and supervision of AWE.
During this intervention the site inspector and I engaged with the licensee by:
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
This intervention did not include a safety system inspection.
The ONR team found evidence that, in the area inspected, the implementation of arrangements for compliance with LC 26 at the site is adequate. In particular, the appointed Project Manager overseeing the contractor's work and the Duly Authorised Person had clear and good understanding of their roles.
The walk down of the relevant area was consistent with these findings. For example, the area appeared well managed, with adequate barriers and protection in place for the packaged waste and demolished buildings. I recommend that ONR continues to monitor progress, to confirm that the radioactive waste materials are being dealt with appropriately and accumulations are minimised.
In the area I considered during the intervention, I found that the implementation of the arrangements for compliance with LC 26 at Aldermaston was to an adequate standard and that no formal ONR action was required.
