Springfields - LC 34 inspection

Executive summary

Purpose of Intervention

This was a reactive unplanned inspection at the Springfields Fuels Limited Licensed Site on the 2 August 2017 to inspect compliance with Licence Condition (LC) 34 - Leakage and escape of radioactive material and radioactive waste, in response to a Deepdale Brook ONR Level 4 issue and an incident notified to ONR on the 6 July 2017.  Reactive unplanned inspections support the wider intervention strategy of the Decommissioning Fuel and Waste Sub-division.      

Interventions Carried Out by ONR

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

The inspection examined a sample of the Licensee’s arrangements and their implementation to enable the closure of ONR regulatory Issue 3246 “LC 34: Leak and escape of uranic material off the nuclear licensed site into Deepdale Brook that exceeds recognised standards (WHO)”; the current land quality management arrangements; and the systems in place to maintain compliance with LC 34 in response to an Incident Notification Form (INF1) received on the 6 July 2017.

 The Licensee is due to review the compliance documentation for LC 34 by the end of 2017 and recommendations to clarify the arrangements for LC 34 were identified due to the focus on the Environment Agency’s (EA) permit requirements. However from the documentation sampled there are adequate arrangements in place to reduce the risk from leakage and escape of radioactive material and radioactive waste, so far as is reasonably practicable. 

The site is currently responding and implementing changes following an incident notified to ONR on the 6 July 2017 related to a leak and escape of radioactive material and radioactive waste from a storage tank. It is my opinion that the arrangements sampled during the inspection, following the incident, provide adequate compliance with LC 34 and it is my expectation that lessons learnt will be promulgated site-wide and implemented within the safety case documentation for all facilities.  The full-investigation report will be reviewed by ONR in due course for compliance with the other Licence Conditions.

Conclusion of Intervention

In my opinion the Licensee’s arrangements for compliance with LC 34 were adequate from the documents sample inspected and the operations observed during the intervention.
