Executive summary

ONR regulates the civil transport of radioactive material by road, rail and inland waterway in Great Britain (GB). The ONR Transport Competent Authority (TCA) is responsible for delivering non-nuclear transport inspection and enforcement activities. This inspection forms part of that delivery function with reference to Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (CDG), the Ionising Radiations Regulations 2017 (IRR17) and the Radiation (Emergency Preparedness and Public Information) Regulations 2019 (REPPIR19). CDG refers to the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) and ONR used ADR 2021 during this inspection (

Purpose of Intervention

The purpose of the inspection was to review Unitech Services Ltd’s arrangements associated with the road transport of radioactive material. ONR carried out this inspection at the Crumlin site on 21 July 2022.

Interventions Carried Out by ONR

The chosen inspection sample included:

  • notification, registration or consent – IRR17 Regulation 5, 6 or 7;
  • a suitable and sufficient radiation risk assessment (RRA) – IRR17 Regulation 8;
  • suitable and sufficient measures to restrict exposure – IRR17 Regulation 9;
  • suitable and sufficient Contingency Planning and/or Emergency Arrangements – IRR17 Regulation 13 and CDG 2009 Regulation 24 & Schedule 2;
  • adequate information, instruction and training – IRR17 Regulation 15 and ADR 1.3.1;
  • adequate Transport Documentation – ADR 5.4;
  • adequate Security arrangements – ADR 1.10;
  • Equipment on Board – ADR; and
  • a suitable and sufficient Management System – ADR 1.7.3.

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

The inspector sampled the arrangements deployed by Unitech Services Ltd for the safe transport of radioactive materials, including the associated arrangements for protecting workers against the effects of ionising radiations and reducing risks as low as reasonably practicable (ALARP).

The inspector compared relevant statutory requirements with both prescribed arrangements and actual practice.  The inspector identified a number of examples of the dutyholder meeting relevant good practice in reducing risk to levels that are ALARP, including adequate management system, suitable contingency plans, appropriate training and instructions. The inspector identified one non-compliance and discussed this during the inspection, which included enhancements required to the radiation risk assessment.

During the inspection, the inspector also suggested certain improvements to transport practices that would be prudent for Unitech Services Ltd to consider.

Conclusion of Intervention

Unitech Services Ltd demonstrated that for certain aspects of its operations it met the requirements of CDG, ADR and IRR17. Based on the inspection sample, the inspector identified one non-compliance with relevant legislation and suggested three improvements. The inspector discussed these during the inspection and Unitech Services Ltd gave a commitment to address them.

The inspector gave Unitech Services Ltd until 12 Sept 2022 to provide ONR either with evidence that the findings have been resolved, or an appropriate resolution plan with timescales for completion.

For this intervention, the inspector assigned an inspection rating of GREEN, due to there being relatively minor deficiencies in compliance arrangements.

ONR will monitor the identified non-compliances through its Issues Management arrangements.
