Reactor 1 statutory outage 2021 Radiological Protection inspection

Executive summary

Purpose of Intervention

This report is on ONR’s assessment of EDF Energy Nuclear Generation Ltd’s (henceforth referred to as the Licensee) radiological risk management arrangements during the 2021 statutory outage of reactor 1 at its Torness site. The site intervention sought to establish if the license’s statutory outage work programme was being conducted in compliance with the Ionising Radiations Regulations 2017 (IRR17). This will inform the ONR decision relating to the issue of a Licence Instrument for Consent for return to service of Reactor 1 at Torness.

The aim of the RP intervention was:

Interventions Carried Out by ONR

The intervention focussed on the following during the opening meeting and plant inspection:

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

The RP inspection did not reveal any significant nuclear safety concerns relevant to the Torness Reactor 1 outage that require action by the Licensee or further follow-up by ONR.

Discussions with the Head of Radiological Protection for Torness gave me suitable assurance that there is effective RP practice in place; an adequate level of compliance with the requirements of IRR’17 was noted by the RP staff from the NGL corporate centre.

An inspection rating of Green was therefore assigned against IRR’17.

Conclusion of Intervention

I identified no matters that should prevent ONR granting Consent under license condition 30 allowing the Licensee to return Torness Reactor 1 to power in due course.
