Second meeting of INAGO, INAGO-2

The second meeting of INAGO, INAGO-2, took place in December in Helsinki. The purpose of the meeting was to discuss and clarify the comments and recommendations of INAGO-1, to examine STUK’s Issue List and Posiva’s plans for resolving these issues, to consider Posiva’s plans for quality management and to discuss STUK’s review of TKS-2003 and Posiva’s response to this review.

The status of the ONKALO programme was presented to the members of INAGO and was followed by a discussion on the issues raised at the first INAGO meeting, in particular the need for the amount of tunnel mapping that Posiva are currently carrying out, the use of geophysics in the site characterisation programme and the question as to why some boreholes had been left open. In its closed session INAGO had a comprehensive discussion on tunnel mapping and the use that should be made of Pilot holes, that are drilled down the ONKALO’s access tunnel ahead of its construction. Following these discussions, they made recommendations to Posiva on the type of underground investigations that they considered most appropriate.

Extensive discussion also took place regarding STUK’s Issue List, in particular those issues which STUK consider are of immediate concern. INAGO members were generally supportive of Posiva’s response to these issues and considered that their programme took STUK’s comments into account. INAGO look forward to receiving the new reports which Posiva are in the process of producing, which specifically relate to the resolution of these issues.

Posiva’s plans for quality management were well received by INAGO and considered as appropriate for use in the ONKALO. The issues raised by INAGO at their first meeting were also discussed – in the majority of cases the issues had been resolved, whereas in others Posiva agreed that further work was still required. Posiva’s TKS-2003 report sets out their programme of work for the period up to 2006, and the issues raised by STUK’s review of this report are generally included within their own Issue List, with the result that Posiva are already dealing with these matters.
