Belgium/China/Germany/France/Pakistan Future Research Participation Interest Belgium: Even if the vehicles used for RAM shipment is not battery powered, but the package may be also impacted by battery fire caused by other vehicles considering the increasing market of battery powered vehicles. Hydrogen powered vehicles haven t become so common. 6/8 2/8 Additional Information 6

Recommendation from the Survey Limited current activities or regulatory frameworks for battery and hydrogen vehicle used in radioactive material transport Consider establishing a CRP to explore potential impacts and develop appropriate regulations Summary 7

Assessment process of a CRP TRANSSC Secretary TSU will take the task to get the approval of CRP proposal New Proposal entered in CRA-Online and sent by NACA to PO for evaluation Proposal evaluated by PO, technical approval by SH and sent back to NACA Administrative approval by SH- NACA Contract/Agreement Proposal sent by research institution to NACA NACA: Research Contracts Administrative Section, NA 8

CRP performance assessment The New CRP is active (i.e., contracts and agreements have been awarded under this CRP) 1st CRP review is prepared after 2 or 3 years by PO, cleared by SH/DIR and submitted by NACA to the CCRA for approval of the CRP continuation Additional Review might be needed if the CRP continues beyond two further years, or an extension/additional funds are required CRP is completed and a CRP evaluation is prepared by PO cleared by SH/DIR and submitted by NACA to the CCRA for approval 9

Funding of the CRP Funded from the RB & EB as an integral part of Agency s approved Programme and Budget. The size of the award may vary considerably with the subject of research, the institute selected, and the amount and source of funds available. seed money ( 6000/y for a typical Research Contract) and cost-sharing basis with the institute absorbing a large portion of the expenditure 10

Funding of the CRP Not meant for salaries and wages, but rather to cover expendable supplies and certain minor items of equipment specifically required for the contract concerned, and not for major items of equipment, building construction or renovation. When equipment is to be purchased on behalf of the contracting institute, to the extent possible, sufficient funds should be made available in the initial year to defray the entire cost involved. It may then be possible to reduce substantially the level of support provided in subsequent years. Funds for transportation or travel should be provided sparingly and only on the condition that such expenditure is essential for the successful undertaking of the work envisaged. 11

Description of the CRP Proposal/WG ToRs Project Name: Potential Effects of Accident Caused Battery and Hydrogen Fires in View of Regulatory Test Requirements for the Safe Transport of Packages of Radioactive Material Project Description: This CRP will explore potential accident scenarios involving hydrogen and battery fires during the transport of radioactive material. It will assess the impact on various shipment types by analyzing frequencies, probabilities, and other relevant factors through a combination of analytical, experimental, and simulation methods. Project Objective: The objective of this CRP is to assess the implications of emerging transport technologies on existing regulatory test requirements, which were established decades ago. It will focus on the unique risks posed by hydrogen and battery fires, evaluating whether the current IAEA regulations remain sufficiently conservative or if revisions are necessary. Expected Output: Statistical analysis of hydrogen and battery fire characteristics Risk analyses of transport scenarios Evaluation of the existing design and test requirements in SSR-6, their applicability and identification of gaps Proposals to fill the identified gaps 12

Choosing Our Next Step Option A: Initiate A CRP Option B: Establish A WG
