Abstract: STUDIES ON LEACHING BEHAVIOR OF THE SIMULATED HLW-GLASS FORM 1．EFFECTS OF TEMPERATURE ON LEACHING BEHAVIORSheng Jiawei;Luo Shanggeng;Tang Baolong(China Institute of Atomic Enerty, P.O.BOX 275(93)，Beijing 102413)Abstract:The effect of temperature on the simulated HL W-glass form is studied．The activation energies are obtained and the rate-controlling process of glass corrosion is determined．The experimental results show that in deionized water，with temperature increasing，the rate-controlling process of glass corrosion is changed from ion-exchange to network dissolution，In simulated under ground water，the rate-controlling process of glass corrosion is ion-exchange，which is independent on temperature. Keywords: Simulated HL W-glass form Leaching behavior Temperature effects Rate controlling process Ion exchange process Network dissolution process
