LC 28 & 32 Compliance Inspection - Sellafield Ltd Active Area Services, Sellafield

Executive summary

Purpose of intervention

The Office for Nuclear Regulation (ONR) undertakes all regulatory interactions with Sellafield Limited (SL), the site licensee, against a strategy defined by the ONR Sellafield, Decommissioning, Fuel and Waste (SDFW) Programme. The planned inspection schedule for the current regulatory year (covering April 2016 - March 2017), the content of which is guided by that strategy, identifies the Licence Conditions (LCs) that will be inspected over this period.

This planned intervention was undertaken to determine if SL's Active Area Services is adequately implementing SL's site-wide arrangements for compliance with Licence Condition 28 (examination, inspection, maintenance and testing) and Licence Condition 32 (accumulation of radioactive waste). The intervention focussed on the Active Area Services laundry facility as it provides an essential duty service to facilitate the overall hazard and risk reduction activities on the site.

The overall adequacy of SL's site-wide arrangements is considered in other inspections.

Interventions Carried Out by ONR

Licence Condition 28 (LC 28) requires the licensee to make and implement adequate arrangements for the regular and systematic examination, inspection, maintenance and testing of all plant which may affect safety.

My inspection, which comprised discussions with SL staff, examination of plant documentation, and inspection of facilities and equipment, focussed on SL's:

Licence Condition 32 (LC 32) requires the licensee to make and implement adequate arrangements for minimising so far as is responsibly the rate of production and total quantity of radioactive waste accumulated on the site at any time and for recording the waste accumulated.

My inspection, which comprised discussions with SL staff, examination of plant documentation, and inspection of facilities and equipment, focussed on SL's:

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable; this was not a safety system based inspection.

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

I consider the licensee is in breach of LC28 requirements as its Plant Maintenance Schedule for the laundry have not been kept up to date with the supporting safety case. I note however, that the licensee is aware of this shortfall from its own recent review. Nevertheless, I consider that this matter is important enough to assign an inspection rating of Amber (seek improvement) against LC28.

I consider the licensee's implementation of its site-wide arrangements for LC32 to be adequate. SL demonstrated with evidence the processing and sentencing of some of its historical solid waste arisings. Its recent appointment of a waste coordinator is proving to be of value and represents good practice. In regard to minor shortcomings I noted, the licensee accepts it is at the start of a journey with further distance to travel. As the shortcomings observed were minor, I have awarded an inspection rating of Green (no formal action) against LC32.

Conclusion of Intervention

My findings were shared with and accepted by the licensee as part of normal inspection feedback. I plan to raise one new Regulatory Issue as a result of this inspection, to track SL's updates of its PMS so that it aligns with the plant safety case.
