een specified yet. Since the size of the harbours and the needs of the transportation system will
not be different than they are today, m/s Sigyn can, in terms of size and characteristics, be used
for the time being as a point of departure in the planning of the shipments to the deep repository
as well, assuming the latter is located in Forsmark.
The terminal vehicles will eventually have to be replaced as well for reasons of age. Old and
new vehicles will be able to work side by side during a transition period.
Any proposed changes in cargo handling will first be studied to make sure that today’s
shipments can also be performed.
9.5.2 Equipment for canister transport
A transport cask for canisters is being designed, see section 9.3.3. Transport frames that can
be handled in the encapsulation plant and in the deep repository, as well as together with the
transportation system’s vehicles and ship, are needed for the new transport casks. The transport
frames will be designed together with the casks.
The planning of shipments to the deep repository is being coordinated with the encapsulation
plant and with the deep repository project, above all when it comes to the equipment for
handling canister transport casks and associated transport equipment.
In addition to technical data concerning size, weight, design of transport frame and the like,
such questions as maintenance of casks, temporary storage of empty or full casks and other
logistics questions for the canister transport casks must be dealt with jointly.
9.5.3 Accounts
A relatively comprehensive account of canister transport forms a part of the account of the deep
repository and will be included in the permit application for the deep repository. A status report
will be included as supporting material with the permit application for the encapsulation plant.
The material will be produced gradually. However, there will not be any extensive investigations,
since a functioning transportation system has been in operation for a long time. The
changes in SKB’s transportation system that will be made up to the time the deep repository is
taken into operation will for the most part be such changes that would have been made anyway
due to the need for modernization and new regulations, agreements or the like.
