HIDRA Project

Human Intrusion in the context of Disposal of Radioactive Waste

Second plenary meeting

The second and final plenary meeting of HIDRA project is planned to be held on 1-5 December 2014. 

Background

Insert image hereIn September 2012, a Technical Meeting was held at the IAEA headquarters to discuss Human Intrusion (HI) and Future Human Actions in relation to Disposal of Radioactive Waste. The discussions focused on various issues such as the difference and commonality of human intrusion scenarios for geological and near-surface disposal facilities and approaches that have been used for such assessments in different countries. As a result of these discussions, a new international projectwas launched: "HIDRA - Human Intrusion in the context of Disposal of Radioactive Waste".

Objectives

The objectives of the HIDRA project are:

  • To share experience and practical considerations for development and regulatory oversight of assessments of impacts of future human actions, primarily human intrusion, in the context of the safety case during the lifecycle for a disposal facility
  • To provide specific information regarding technical, societal and design considerations to support development of a structured process or methodology for developing scenarios for site-specific application
  • To describe the role of assessments of future human actions for siting, design and development of waste acceptance criteria in the context of the safety case
  • To provide suggestions for communication strategies to describe the rationale for assessments of future human actions and for interpretation of the results of those assessments for the public
  • To provide recommendations for WASSC and RASSC, as appropriate, for clarification of existing IAEA Safety requirements and guidance relevant to the assessment of future human actions and human intrusion.

Expected outcome

The expected outcome of this project is to provide guidance on how to address human actions in the safety case and safety assessment of radioactive waste disposal in the future, and then using those assessments to optimize siting,  design and waste acceptance criteria within the context of a safety case.

The two-year project would involve an annual plenary meeting as well as several task group meetings. Each plenary meeting would play a pivotal role in presenting and discussing the scope, content and
outcome of the project. Individual task meetings may be held between plenary meetings to review the progress of specific task activities, and to plan subsequent activities.

Meetings

First plenary meeting

The first plenary meeting of HIDRA was held in November 2013. Core group members (Chairpersons and WG leads) presented current status of WG activities, interaction with other WGs, and work plan during the week.

Following the overview presentations intensive discussions were carried out regarding the methodology on how to select scenarios and protective measures to use to address the HI scenario, and how the factors (developing scenarios, consideration for societal factors, consideration on protective measures etc.) are linked each other in the framework of a safety case.

During the WG sessions participants worked in threeworking groups to improve the current document.

Prior to the conclusion of the meeting progress was reported from each Working Group chairpersonp. Thereafter the future activity plan - to hold the next plenary meeting to be held in 2014, while each WG might organize intermediate group session individually - was agreed by the participants.
