[en] The leaching of highly active French glasses at Studsvik, which have been described earlier, have continued. This report gives analytical data up to 1978-04-03. LWR glasses containing Cs and Sr show considerable difference in the beginning which tend to diminish during stage 5. Observed leach rates are 1-2 x 10^-6 g cm ^-2 day ^-1 at the end of observations. They have a tendency to decrease futher. Increase in temperature from 25 deg C to 60 deg C gave a leach rate increase with a factor of about 10. In all cases but one the leach rate at 60 deg C decreased considerabley with time. For Pu, the leach rate remained approximately constant at 5 x 10^-7 g cm^-2 day^-1 during stages 1 - 3 and beginning of stage 5. After a few weeks of that stage there was a temporary strong increased of Pu leaching, that decayed back to about 5 x 10^-6 g cm^-2 day after about a month. This effect is still unexplainded but may be due to inhomogenity
