The Office for Nuclear Regulation (ONR) undertakes all regulatory interaction with Sellafield Limited (SL, the site licensee) against a strategy defined by the ONR Sellafield Programme. My planned inspection schedule for the current regulatory year (covering April 2014 – March 2015), the content of which is guided by that strategy, defines the Licence Conditions (LC) that will be inspected over this period.
This intervention was undertaken to determine if the Waste Vitrification Plant (WVP) area is adequately implementing SL’s site-wide arrangements for compliance with Licence Condition 7. WVP was selected for this inspection because of the potential for an accident at this plant to have offsite consequences.
Licence Condition 7 (LC7) requires the licensee to make and implement adequate arrangements for the notification, recording, investigation and reporting of incidents occurring on the site.
My inspection, which comprised discussions with SL staff and examination of plant documentation, focussed on the following areas:
Not applicable; this was not a Safety System inspection.
I judge, from the evidence presented, that the site-wide arrangements for compliance with LC7 have been implemented appropriately within the WVP facility. Where the facility has undertaken additional assessment activity as part of their process to manage incidents, I consider that this represents good practice, and should be shared with other facilities on site.
I identified a small number of minor shortfalls in the licensee’s control of delivery timescales for both investigation delivery, and corrective action completion. Having reviewed those shortfalls, I am content that none present any safety concern.
The licensee has adequately implemented its arrangements for compliance with this LC. Given that there were a small number of areas of good practice, but also a number of improvements that could be made, I have recorded an IIS rating of 3 (adequate) against Licence Condition 7 (Incidents on the site).
My observations were shared with, and accepted by, the licensee as part of normal inspection feedback. No ONR Regulatory Issues were raised as a result of this inspection.
