Testing of parameter averaging techniques for far-field migration calculations using FARF31 with varying velocity

Technical Report:

Abstract

This report was prepared for SKB as a part of the SKB 91 performance assessment study. The object of the study was to test different averaging techniques for averaging velocity profiles. The average velocities obtained with the different techniques were used to set appropriate values on the Peclet number, Pe, and the groundwater travel time t{sub w}, and used as input to the FARF31 code. The output from the FARF31 calculations were compared against numerical simulations made with TRUCHN. Three different averaging techniques were tested: volume averaging, flow averaging and a technique based on the principle of additive variances. Four different nuclides were studied, {sup 238}U, {sup 237}Np, {sup 135}Cs and {sup 129}I. Five velocity profiles were tested, four generic profiles and one particle track from the groundwater flow calculations made for the Finnsjoe site. (au).
