Handling
Explanation of how the FEP is treated
Intrusion is considered in the Biosphere Interaction Matrix (SKB R-10-37) but not in the Radionuclide Model (RM). Intrusion is a process at the boundary to the geosphere and is not necessary to consider in the biosphere radionuclide model. In addition, intrusion to repository depth is unlikely for the KBS-3 method. The handling is further described in the SR-Site Biosphere synthesis report, SKB TR-10-09, and in the ecosystem reports, SKB TR-10-01, -02 and -03.
