    On The Possible Leakage of ET-RR1 Liquid Waste Tank: Hydrological and Migration Modes Studies by N. S. Mahmoud, S. T. EL-Hemamy

    Published 2005-01-01
    “…Therefore, at present, it faces a serious problem due to aging equipment, especially those directly in contact with the environment such as the underground settling tanks of nuclear and radioactive waste. The possible leakage of radionuclides from these aging tanks and their migration to the aquifer was studied using instantaneous release.This study was done based on the geological and hydrological characteristics of the site, which were obtained from the hydrogeological data of 25 wells previously drilled at the site of the reactor[1]. …”
