SKB International announces “School of Geological Disposal” to be held 22-26 October 2018, at the Äspö Hard Rock Laboratory, Sweden.

Update on 5/07/18: A few seats are still available, please contact Erik Möller for further information about registration.

SKB International and SKB are delighted to offer a scientific training course covering important issues governing a national nuclear waste disposal programme.

Based on the experiences gained by SKB during the past 40 years the course will present the planning and execution of a successful programme. The starting point is a strategic and graded approach with an early safety prediction via detailed understanding of processes, research achievements and gains in correctly defined targets and how this leads to a communicative safety case based on a solid and well defined safety assessment.


The overall objective of the training course is to provide participants with an understanding on how to acquire the relevant knowledge needed to start or proceed in the development of a safety case and safety assessment for a geological nuclear waste disposal facility.

Participant Profile

The course is suitable for employees in waste management organisations, regulators and supporting technical organisations with a few years of experience in safety assessment, engineered barrier development and/or repository design.

Course Content

The course is given by senior experts from SKB, many with a world renowned reputation in their field, and will cover the relevant topics for geological disposal of nuclear waste. The course programme will launch from the fundamentals of safety assessment and its defined safety functions. We will present SKB’s experiences and knowledge based on selective research, successful experiments confirming assumptions and share experiences gained from failures. The lectures and discussions will provide extensive, profound information coupled to cutting edge applications when applicable. We aim to transfer theoretical knowledge and practical experience to the course participants efficiently and effectively all in an informal and inclusive atmosphere encouraging open discussions and networking.

Attendants will obtain course material (English), information material about SKB, and general information on Oskarshamn such as map, tourist information, etc. during the welcome reception to further enhance the positive experience of the course.
