Table 4. Current situation and preliminary interim goals for certain design issues, according to Table 3A.
Design issue/
subsystem
Current situation, reference D1 – permit application for
encapsulation plant
D2 – permit application for deep
repository
Infrastructure and layout for facility
parts above ground
Location and disposition of functions
in relation to local conditions.
Generic design basis and reference
solutions exist. First site adaptation
done during step D0.
Alternative locations and preliminary
configurations presented.
Environmental aspects preliminarily
analyzed.
Main alternative chosen and
justified. Configuration presented
for this alternative. Environmental
aspects analyzed and described.
Access alternatives
Various combinations of shafts and
inclined tunnel (ramp) can be chosen
for transport and communications.
Comparative analyses done of
alternative solutions.
Reference: Separate shafts for
personnel transport and rock
hoisting, ramp for transport of
transport casks with canisters.
Locations for shafts, or route for
ramp, preliminarily determined and
justified. Environmental aspects
preliminarily analyzed.
Locations and dimensions for
shafts chosen. Possible execution
described. Revised route for ramp
described. Environmental aspects
described.
Rock spoil
Handling procedure for excavated
rock from removal to end use.
Location of facilities, transport roads.
Handling alternatives, preliminary
market situation etc have been
analyzed.
Proposals for handling procedure
studied, alternative locations of
facilities presented. Environmental
aspects preliminarily analyzed.
Handling procedure and technical
solution presented for prioritized
alternative. Environmental aspects
analyzed and described.
Ventilation below ground
System solutions and rating. Preliminary assessment of the
ventilation requirement is included
in the reference design.
Preliminary rating of the ventilation
system based on the requirement
for the facility’s underground part,
including principles for design of fire
ventilation and fire cells.
Ventilation system rated for
ventilation requirement of the
facility’s underground part,
including principles for design
of fire ventilation and fire cells.
Main and construction documents
Requisite documents for procurement
of contracts for site preparation and
infrastructure.
Documents for executing the works
on the site prepared, checked and
approved.
Handling procedure and technical
solutions chosen and approved.
Ventilation requirement during
construction and operating
phases clarified so that requisite
procurements can take place as
needed.
