Hartlepool Nuclear Licensed Site Control of Occupational Radiation Exposure project Intervention

Executive summary

Purpose of intervention

This report describes an inspection of the EDF Hartlepool Power Station, undertaken as part of the planned ONR cross sites intervention, which is looking at Control of Radiation Exposure (CORE) across all GB nuclear sites.

Additional to the CORE inspection was an inspection of the procedures and records associate with sealed source leakage testing and record keeping; regulations 27(3) and 28 of IRR99.

Interventions Carried Out by ONR

The intervention was conducted principally under regulation 8, ‘Restriction of Exposure’, of the Ionising Radiations Regulations 1999.  To ensure consistency with previous inspections at other nuclear sites, the inspection was conducted using a standard questionnaire and follow up face-to-face question and answer session with representatives at Hartlepool. During the intervention we inspected the arrangements for controlling radiation exposure by inspecting a number of areas including the pile caps, refuelling area, active maintenance facility, irradiated fuel disposal facility and basement area.   

Explanation of Judgement if Safety System Not Judged to be Adequate

This intervention did not include a safety system based inspection.

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

Compliance with the requirements of the IRR99 was judged overall to be adequate. ONR noted that in relation to the control of occupational radiation exposure, Hartlepool is performing at a similar standard to other reactors within the Fleet and that EDF is effectively leading the industry in the standards it adopts.  

ONR advised on a number of areas for improvement in order to achieve a better alignment with relevant good practice. These are:

Whilst leakage testing and source record keeping procedures appear compliant, the electronic source record documentation appeared to require improvement and the Station have been requested to ensure that the records contain all of the statutory information and where practicable relevant additional information. A Level 4 issue has been raised to monitor progress.

A more detailed set of ratings for each of the eight CORE criterion is also presented in this report.

Conclusion of Intervention

In conclusion, it was considered that a Green IIS rating was appropriate for the CORE inspection with some opportunities for further improvement identified which were discussed and agreed with the licensee.
