Table 3a. Important issues for site-adapted design. Solutions for the deep repository are based
for the most part on existing knowledge and technology that is adapted to the requirements of
the deep repository and conditions on the site. Interim goals for design are shown in Table 4. A
plus sign indicates important links that must be taken into account in the design work.

Table 3b. Important issues for site-adapted design. Solutions for the deep repository are based
for the most part on own technology development, cf section A4.4. Interim goals for design are
shown in Table 5. A plus sign indicates important links that must be taken into account in the
design work.
