Transport inspection - Trawsfynydd

Executive summary

Purpose of intervention

The purpose of the inspection was to:

Sample the adequacy of the arrangements for the transport of radioactive material, and compliance with the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 at Trawsfynydd.

To develop ONR’s understanding of the current and future activities at Trawsfynydd in regard of radioactive materials transport and how these relate to the wider Magnox estate, including the arrangements for transport emergencies.

Interventions Carried Out by ONR

The inspection was conducted through a visit to the Trawsfynydd site, interviews with staff and documentary review.

The inspection was conducted  against the requirements of the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 SI 2009:1348 (CDG 09), a relevant statutory provision of the Energy Act 2013, and one which requires carriage by road to be in accordance with the appropriate edition of a European Agreement known as ADR. The current edition is ADR 2015. In particular, although not exclusively, the inspection considered arrangements in respect of ADR 1.7.3 – Management System, ADR 1.3 - Training, ADR 1.8.3 - Safety Advisor, and CDG 09 Regulation 24 – Radiological Emergencies. 

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A – not a System/Structure Based Inspection.

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

The inspection found current arrangements for packaging and consignment of Class 7 material (exempt  excepted and IP2 packages, in addition to unpackaged low specific activity (LSA I) material) to be adequate for the purposes of ADR, and in compliance with the requirements of CDG09.

No findings were made for Trawsfynydd to consider further to the visit.

The inspector was satisfied that the current arrangements for carriage of Class 7 material did not present a significant risk to workers or the public. Consequently, no formal regulatory action was considered necessary on this occasion.
