Partitioning of u in bottom sediments of
mayak reservoir R-17
Abstract
Partitioning of 234,238U in
bottom sediments of Production Association Mayak reservoir R-17 was
investigated. Uranium isotopes were found in all fractions carried out by
sequential extraction. The maximum content was found in the fraction associated
with carbonates (29–33%). In the conditions of the V-17 reservoir of the Mayak
Production Association, uranium is washed out of bottom sediments by surface
waters. It can be assumed that the mechanism of radionuclide migration will be
ion transport of carbonate complexes.
Key words: PA "Mayak", 234, 238U,
sequential extraction, bottom sediments.
