Planned joint compliance inspection with the Environment Agency

Executive summary

Purpose of Intervention

    A planned joint intervention with the Environment Agency, to inspect the implementation of the licensee’s arrangements to remediate some minor contamination beneath the site. I discussed a recent minor event which resulted in an elevated radiation dose to a plant operator. I also participated in the planned Springfields Site Stakeholder Group meeting, held near the site, reporting on recent ONR interventions at Springfields. The intervention formed part of the planned 2016/2017 Intervention Programme for the Springfields Fuels Limited site.

Interventions Carried Out by ONR

A meeting was held to discuss a recent event on the site, where an operator had incurred a small radiation dose uptake.

I inspected aspects of the licensee’s implementation of compliance arrangements, relating to the control of the leakage and escape of radioactive material and radioactive waste on the site, as a joint intervention with the Environment Agency. The intervention was informed by ONR’s guidance requirements (as described in our technical inspection guides, which can be found at in the area inspected, specifically the Technical Inspection Guide for Licence Condition 34, NS-INSP-GD-034, Rev 3, April 2016. Further information on intervention ratings is available at

I participated in the planned meeting of the Springfields Site Stakeholder Group, held near the site, reporting on recent ONR interventions at Springfields.

Explanation of Judgement if Safety System Not Judged to be Adequate

As no safety system inspection was undertaken, this was not applicable to this intervention.

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

I discussed the licensee’s investigation into a recent event where a plant operator had incurred a small internal radiation dose. I was satisfied that the licensee had duly rigorously investigated this matter and had promptly implemented some improvements which would reduce the likelihood of a recurrence.

I conducted a joint compliance intervention with the Environment Agency, inspecting aspects of the licensee’s implementation of Licence Condition 34 arrangements. This was at a meeting to inspect the remediation of historic very low levels of uranium contamination in the ground beneath part of the site.

At the meeting of the Springfields Site Stakeholder Group, I reported on recent ONR interventions at Springfields and addressed some queries from the members.

Conclusion of Intervention

I concluded that the licensee had adequately investigated a recent minor radiation dose exposure to a plant operator. No intervention rating was warranted for this meeting.

I concluded that an inspection rating of green, adequate, was warranted for the planned joint intervention with the Environment Agency. The licensee adequately demonstrated the timely implementation of aspects of licence condition 34 compliance arrangements, in relation to a ground contamination Issue. I concluded that there were no matters that may significantly impact on nuclear safety.

I concluded that the Springfields Site Stakeholder Group meeting provided a useful opportunity to enable ONR to report on recent site interventions to the members of the Stakeholder Group. No intervention rating was warranted for this meeting.
