The NAWG-15 workshop will be an opportunity to explore recent developments in the use of natural analogues (NA) in supporting safety cases (SC) for the disposal of radioactive wastes. Argumentation by use of analogy is well established in many fields including philosophy, biology, linguistics and law and most scientists are familiar with this approach and will have used it at some point in their career. If you are keen to learn more, why not come along? Currently, the programme looks like this:

Tuesday 23rd May.

Session I: To explore the current use of NA in developing and supporting the Safety Case. Examples from the Finnish and UK programmes, along with a short overview from an international project, will set the scene and the topic will be discussed within smaller groups in the afternoon.

Morning
TimeDescription
08:45 Welcome from Venda Havlova (UJV, Rez, our local host) and introduction to the workshop from Russell Alexander (NAWG)
09:00 Current status of the Czech programme – tbc (SURAO, Czech Republic)
09:15 Use of NA in the UK SC – Simon Norris (RWM Ltd, UK)
10:15 Coffee
10:45 Safety Case communication - Interim report of the NEA Integrated Group for the Safety Case – Ulrich Noseck (GRS, Germany)
11:15 Use of NA in the Finnish SC – Heini Reijonen (GTK, Finland)
12:15 Lunch
Afternoon
TimeDescription
13:30

Discussion in small groups. Points to be considered include:

  • relative weighting of laboratory and modelling results and NA
  • ‘ground truthing’ of modelling results via NA input – is that the limit?
  • Why so little NA in SC, does it have an image problem?
15:15 Coffee
15:45 Presentation of main points from the discussion
16:15 Open floor discussions on new topics
17:30 Close of Session I Train at 17:52
17:30 – 18:30 Session II: Poster session Posters will remain in place until the end of the workshop. Train at 18:52

Wednesday 24th May.

Session III: Explore the current use of NA in communicating both the results of the SC and the wider aspects of radioactive waste disposal

Morning
TimeDescription
09:00 Use of NA in communications: 1. experience from the Canadian programme – Erik Kremer (NWMO, Canada)
10:00 Use of NA in communications: 2. EU-research project Carbon-14 Source Term Erika Neeft (Covra, The Netherlands)
10:30 Coffee
11:00 Use of NA in communications: 3. potential use in the Japanese programme – Ken Kaku & Kunio Ota (NUMO, Japan)
12:15 Lunch
Afternoon 

Facilitated round table discussions will bring forth any remaining questions and topics from the main presentations for open discussion among all participants. Points to be considered include:

TimeDescription
13:30

Discussion in small groups. :

  • can we use the same NA information in different ways for different audiences?
  • how do the positions of different audiences affect their reception of different natural analogue and could this inform how NAs are presented?
  • can we agree on what defines those audiences (e.g. local communities/regional communities/different levels of government/implementers & regulators/watch-dog groups)?
15:15 Coffee
15:45 Presentation of main points from the discussion
16:15 Open floor discussions on new topics
17:30 Close of Session III Train at 17:52
19:00 Workshop Dinner Venue to be announced

Thursday 25th May.

Session IV: To explore the potential for using NA in staff training and education. Proposed use of NA projects/material in this role will be presented and, as a juxtapose, examples from past projects will set the scene and the topic will then be discussed using AN software.

TimeDescription
09:00 How can we use NA in staff training and education? Some comments from Kunio Ota (NUMO, Japan)
09:45 Training in NA projects: some examples Russell Alexander (Bedrock Geosciences, Switzerland)
10:15 Coffee
10:45

Round table discussion. Points to be considered include:

  • could you envisage your organisation using NAs in this form?
  • Why has training not been a greater focus in past projects?
  • can NAWG play a role here (and, if yes, what)?
12:15 Lunch

Session V: to present an updated view (with recent examples) on the use of archaeological analogues in the SC.

TimeDescription
13:30 - 14:15 Introduction: a critical overview of the use of archaeological analogues in support of the SC and in communication: where can we go from here? tbc
14:15 – 14:45 Archaeology analogues for geological disposal of spent nuclear fuel (SNF) - current status and future outlook in Taiwan – Polly Tsai (INER, Taiwan)
14:45 – 15:15 Natural glasses as NA for vitrified HLW – Venda Havlova (UJV, Czech Republic)
15:15 – 15:30 Coffee

Session VI: General topics (e.g. long-term behaviour of bentonite, natural glasses, model testing, etc)

TimeDescription
15:30 – 15:50 Long-term behaviour of bentonite (LPB) – preliminary project results – Tatsuya Kijima (NRA, Japan)
15:50 – 16:10 Bentonite studies in the Czech Republic – tbc (SURAO, Czech Republic)
16:10 – 16:30 Matrix diffusion revisited – Richard Metcalfe (Quintessa, UK)
16:30 - 16:50 tbc
16:50 wrap-up, Russell & Venda. Close of workshop

Friday, 26th May - Session VII: Field trip to SÚRAO’s Bukov URL in the former Rozna uranium mine

These are but a few examples and we are open to any suggestions to broaden the scope of the meeting - please drop Russell Alexander (the NAWG Chairman) a line with your ideas and comments at This email address is being protected from spambots.
