TESTING AND EVALUATION OF SOLIDIFIED HIGH LEVEL WASTE FORMS
A second joint programme of the European Atomic Energy Community was started in 1981 under the indirect action programme (1980 - 1984), Action No. 5 "Testing and evaluation of the properties of various potential materials for immobilizing high activity waste". The overall objective of the research is to test various European potential solidified high level radioactive waste forms so as to predict their behaviour after disposal. The most important aspect is to produce data to calculate the activity release from the waste products under the attack of various aqueous solutions. The experiments were partly formed under waste repository relevant conditions and partly under simplified conditions for investigating basic activity release mechanisms. The topics of the programme were: (i) studies of basic leaching mechanisms; (ii) studies of hydrothermal leaching and surface attack of waste glasses; (iii) leach tests carried out in contact with granite at low water flow rates; (iv) static leach tests with specimen surrounded by canister and backfill materials; (v) specific isotope leach tests in slowly flowing water; (vi) leach test of actinide spiked samples; (vii) leach tests of highly radioactive samples; (viii) leach tests of alpha radiation stability; (ix) studies of mechanical stability; (x) studies of mineral phases as model compounds and phase relations.
