Planned intervention at Bradwell
- Site: Bradwell
- IR number: 16-147
- Date: November 2016
- LC numbers: 4, 32
Purpose of intervention
This report covers an inspection of Magnox Ltd’s Bradwell nuclear licensed site on 22th to 24th November 2016. This inspection was conducted as part of a programme of planned interventions as outlined in the Bradwell Integrated Intervention Strategy (IIS) for 2016/17.
Interventions Carried Out by ONR
During this intervention, We assessed the suitability of the arrangements for the site’s compliance with Licence Condition 4 (LC 4) – Restrictions on Nuclear Matter on the Site and LC 32 Accumulation of Radioactive Waste. This inspection was undertaken as part of the continuing programme of decommissioning aimed at the site entering care and maintenance operational status later next year.
The intervention was carried out against the requirements of LC’s 4 and 32 and ONR’s published inspection guidance for this Licence Condition.
Explanation of Judgement if Safety System Not Judged to be Adequate
This intervention did not include an inspection of a safety system.
Key Findings, Inspector's Opinions and Reasons for Judgements Made
- Licence Condition 4 – Based on our sample the arrangements at Bradwell site for nuclear matter are such that it is stored separately from other material. There are adequate means of controlling access to the storage areas which have been specially designed or modified for the purpose. There is a clear storage array for material in the ISF and adequate records are maintained including package/container details and markings/labelling. Therefore we have rated compliance with LC4 as Green.
- Licence Condition 32 - Based on our sampling the amount and locations of FED and ILW wastes on site are properly understood and waste is not being generated or processed in a manner which is incompatible with pre-existing treatment and disposal routes. Key characteristics of the waste are properly recorded and the waste containers are kept in pristine condition to meet the requirements of the fLoC for eventual disposal. The processing and packaging of the waste material includes steps to minimise the amount and volume of the waste produced and good learning from operational experience was demonstrated in respect of the surface damage to the containers from the FAVORIT heating jacket. Therefore we awarded a rating of adequate (Green).
The preparations for the entry to care and maintenance operations (C&M) are nearing completion and a sound process for managing the transition to C&M is in place. It is anticipated that the formal submission for entry to C&M will be made in mid 2017.
Conclusion of Intervention
From the evidence gathered during this intervention, I concluded that there are no matters of nuclear safety concern. I have therefore rated the licensee’s compliance with Licence Conditions 4 and 32 to be adequate (green).
