In line with the 2016/17 inspection plan for Dounreay I carried out planned inspections and other interventions to provide confidence that Dounreay Site Restoration Ltd. (DSRL) is controlling its hazards properly and complying with its statutory obligations.
I undertook compliance inspection against Licence Condition 23 Operating Rules and Licence Condition 24 Operating Instructions within the waste processing facility and analytical laboratory.
I sampled the Safety and Environmental Limits and Conditions document which summarises the safety management requirements (SMRs) and safety related equipment (SRE) derived from the safety case. SRE is maintained within operating limits in accordance with the plant maintenance schedule. I confirmed that maintenance had been completed. I also sampled check sheets that demonstrated that operating limits and conditions had been met. I sampled operating instructions and watched the completion of an operation to replace a glovebox manipulator. The work pack demonstrated that the steps within the operation had been signed off as required by the operating instruction.
I concluded that my inspection had found an adequate standard of compliance with licence conditions 23 and 24 when considered against ONR expectations as described in NS-INSP-GD-023 Revision 4 LC 23 Operating Rules and NS-INSP-GD-024 Revision 3 LC 24 Operating Instructions.
The intervention did not identify any matter impacting on nuclear safety that required immediate regulatory action.
