1st Regulatory Workshop
PEBS Workshop for Regulatory Authorities, preliminary programme
The workshop will be arranged as a closed workshop open only to experts of European/global regulatory authorities and their partners/contractors. The objective of the workshop is to present the current status on how processes in the early evolution may affect the long-term performance of the Engineered Barrier System (EBS) of a nuclear waste repository and how the activities within the PEBS project may reduce the uncertainties in the handling of these processes.
The programme will contain:
- Introduction to the PEBS project: objective, partners, activities and expected impact.
- Overview of the current treatment of the early evolution of the EBS in safety assessments in a number of European national programmes. This includes the safety assessment methodology, the use of safety functions, the identification of important processes, assessment of the early evolution and the identification of key uncertainties. A plan for how the scientific work performed within PEBS will be used to reduce uncertainties in future assessments will also be presented.
- The experimental work within PEBS. PEBS includes a large experimental programme at laboratory, mock-up and field scale. The work is focused on the H-M, THM and THMC couplings. This topic will consist of an overview of all experimental work within the project as well as two detailed presentations of specific experiments.
- Model application and development within PEBS. The objective of the modelling is to perform coupled HM, THM, and THMC analyses to provide a sound basis for the interpretation of the various tests within the experimental programme. This also includes the development of new or improved models as demanded by the calibration of computation results with the actual measured data, and use of the the data and improved models for extrapolation to long-term evolution of the repository. In the workshop an overview of the modelling will be given together with specific presentations on coupled thermal-hydraulic-mechanical modelling of the bentonite buffer and coupled thermal-hydraulic-chemical modelling taking into account (certain) mechanical effects.
- Questions and discussion

Bentonite training course and workshop (PEBS Bentonite week)
PEBS is offering a special laboratory training workshop on bentonites for HRLW disposal, and a related field trip to bentonite deposits and producers.
Objectives of training course and excursion
The Bentonite week is aimed at early-stage re-searchers as well as experienced scientists working for universities, implementers and regulators entering this research area with e.g. a. geomechanics or mineralogic background.
Background
Compacted bentonites are currently being investigated as a geotechnical barrier in high-level radioactive waste (HLRW) repositories due to their low permeability, high swelling pressure, and cation adsorption capacity. Bentonite properties vary significantly from one deposit to another and even between different locations of a given deposit. During the training course in the lab both cutting edge and recently implemented methods for bentonite characterisation are presented. The theoretical background as well as training in the lab will cover the current industrial, environmental and economical demands of globally operating organizations.
Of special importance for future installations of final repositories will be an optimal specification of the bentonite raw material for the technical application which should also cover economical aspects.
The desired and required bentonite properties are diverse. Information about the relation between bentonite properties and performance is required to define reasonable bentonite specifications. The ideal HLRW bentonite, capable of rendering all problems negligible, has, however, jet to be identified.
At the end of the training course, the field observations, and the bentonite processing in the clay industry, an open discussion should resolve the quetions of "what kind of quality parameters for bentonites are required?”
