Licence Conditions 32 and 34 compliance inspection

Executive summary

Purpose of Intervention

This was a planned Office for Nuclear Regulation (ONR) / Environment Agency (EA) joint intervention at the EDF Energy Nuclear Generation Limited (NGL) Heysham 1 Power Station undertaken as part of a series of planned interventions listed within the Heysham 1 Integrated Intervention Strategy 2018/2019. The intervention was carried out to assess EDF NGL’s compliance with Licence Condition (LC) 32 (accumulation of radioactive waste) and LC34 (leakage and escape of radioactive material and radioactive waste).   

Interventions Carried Out by ONR

The intervention focused on the licensee’s arrangements and their implementation for compliance against the following Licence Conditions, and made use of the relevant ONR Technical Inspection Guides (TIG):

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

LC32 compliance inspection

On the basis of the evidence sampled, and my interactions with EDF NGL staff, I judge that:

Overall, I consider that the standard of compliance was consistent with relevant good practice and I am satisfied that the licensee is complying with its legal duties. Potential improvements in relation to the storage of acid within the decontamination workshop were identified; these will be addressed through the facility improvement team. No issues have been raised, so an inspection rating of GREEN is appropriate.

LC34 compliance inspection

On the basis of the evidence sampled, and my interactions with NGL staff, I judge that:

Overall, I consider that the standard of compliance was consistent with relevant good practice and I am satisfied that the licensee is complying with its legal duties. No issues have been raised, so an inspection rating of GREEN is appropriate.

Conclusion of Intervention

There are no findings from this intervention that could undermine nuclear safety at this time. Therefore, no additional regulatory action is needed over and above the planned interventions at Heysham 1 Power Station.
