처분부지의 수리지질특성
Hydrogeological characteristics of the LILW disposal site
Abstract
Korea Hydro and Nuclear Power Company (KHNP) conducted site investigations for a low andintermediate-level nuclear waste repository in the Gyeong Ju site. The site characterization workconstitutes a description of the site, its regional setting and the current state of the geosphere andbiosphere. The main objectives of hydogeological investigation aimed to understand thehydrogeological setting and conditions of the site, and to provide the input parameters for safetyevaluation. The hydogeological characterization of the site was performed from the results ofsurface based investigations, i.e geological mapping and analysis, drilling works and hydraulictesting, and geophysical survey and interpretation. The hydro-structural model based on thehydrogeological characterization consists of one-Hydraulic Soil Domain, three-Hydraulic RockDomains and five-Hydraulic Conductor Domains. The hydrogeological framework and thehydraulic values provided for each hydraulic unit over a relevant scale were used as the baseline forthe conceptualization and interpretation of flow modeling. The current hydrogeologicalcharacteristics based on the surface based investigation include some uncertainties resulted fromthe basic assumption of investigation methods and field data. Therefore, the reassessment of hydro-structure model and hydraulic properties based on the field data obtained during the construction isnecessitated for a final hydrogeological characterization.
