Radiological Protection Inspection - Reactor 1 (R1) Statutory Outage 2014

Executive summary

Purpose of intervention

The ONR Civil Nuclear Reactor Programme's Radiation Protection Plan provides for two radiation protection interventions to be completed during Licensee statutory maintenance and inspection outages: one prior to outage commencement and another during its conduct.

This report is on the second such intervention at EDF Energy Nuclear Generation Limited's site at Torness, Scotland.

Purpose of intervention

The intervention described in this report was conducted so that I could gain regulatory assurance that the Licensee was continuing to operate in compliance with the requirements of the Ionising Radiations Regulations 1999 and in accordance with relevant good radiological protection practice in readiness for its bringing maintained plant back into electricity generation.

Interventions carried out by ONR

I considered the following matters during the intervention:

The licence conditions were inspected against ONR's published guidance requirements (as described in our technical inspection guides).

Key findings

The intervention didn't reveal any radiological protection issues that required action by the Licensee or follow-up by ONR in advance of start-up.

Conclusion of intervention

From a radiological protection standpoint, I am content with the Licensee's current state of readiness and preparation for plant start-up in due course.


There were no specific recommendations at the time of writing. The planned interventions set out in the integrated intervention strategy for the Torness outage remain valid and will be followed for future inspections.
