RD&D-Programme 2004 - SKB

Newfound knowledge since RD&D 2001
Experience within the framework of the conclusions in RD&D 2001 is being documented.
No new separate analysis of the canister factory has been done.
Programme
The lessons learned from the trial fabrication of all canister parts will be applied to and
influence the further development of the factory. The work of investigating and establishing
acceptance criteria and testing methods will make it possible to specify modified equipment
for NDT and other quality inspection more precisely. A more thorough evaluation of modified
machinery and testing equipment will be done in cooperation with potential suppliers. This will
provide opportunities for a more precise analysis of the factory’s layout and investment costs.
If the development of friction stir welding shows that the technique may be suitable for sealing
the canisters, the consequences of this need to be examined and weighed into factory layout and
investment costs.
In order to get a complete picture of potential uncertainties, a risk analysis will be conducted of
operations in the planned canister factory.
A detailed timetable coordinated with SKB’s main timetable will be prepared.
A technical description of the canister factory will be appended to the permit application for
the encapsulation plant. However, the siting work for the canister factory is not expected to be
finished at the time of the permit application for the deep repository.
