Dounreay DRSL Ionising Radiations Regulations 1999; Regulation 8: Control of Occupational Radiation Exposure (CORE) Inspection

Executive summary

Purpose of intervention

In line with the 2014/15 inspection plan for Dounreay I carried out an inspection of Dounreay Site Restoration Ltd. (DSRL) for compliance with Regulation 8 of IRR99 - the Control of Radiation Exposure (CORE).

Interventions carried out by ONR

This intervention at the Dounreay Restoration Site Limited site adopted the same, consistent approach that is to be used for all CORE interventions across the industry.

The intervention was segregated into two elements: the first element to assess the general arrangements for restricting worker exposures under regulation 8 and the second element to involve the inspection of a specific work area or activity in order to ensure that the arrangements are being applied at the point of work.

Explanation of judgement if safety system not judged to be adequate

No safety system inspection was undertaken, hence this is not applicable.

Key findings, Inspector's opinions and reasons for judgements made

The licensee provided evidence that it is compliant with Regulation 8 of the Ionising Radiation Regulations 1999 to reduce operational exposure to as low as is reasonably practical (ALARP), hence the overall rating of adequate.

The licensee has adequate arrangements in place with regard to dose targets and investigation, the trending of dose and radiological survey data, the reporting and reviewing of radiological events, providing information, instruction and training, and benchmarking.

Conclusion of intervention

From the evidence gathered during this intervention, I do not believe there are any matters that currently impact on nuclear safety. I am of the opinion that the licensee has demonstrated adequate compliance with Regulation 8 of IRR99, and consequently I have allocated an overall rating of 3 (adequate) for this intervention in accordance with the IIS.
