| 講演要旨(和文) | | 高レベル放射性廃棄物等の地層処分事業では，3段階の調査（文献調査，概要調査，精密調査）を経て処分場を選定する．このうち概要調査段階では物理探査等を実施し，前段階の文献調査で作成した地質環境モデルを更新する作業を実施する．ここでは電中研横須賀地区において実施した物理探査の実証試験を通じて，当該地区のような沿岸域に位置する地域において地質環境モデル構築に必要な地下深部情報の取り扱いについて検討した結果について説明する． |

| | 講演要旨(英文) | | The high level radioactive waste program requires a stepwise approach as literature survey, preliminary investigation and detailed investigation, finally leading to the rational selection of a geological disposal site. In the preliminary investigation stage which is the second stage of three steps of siting, NUMO plans to carry out the ground geological survey, geophysical prospecting and drilling for updating the fundamental geological environment model that is built in literature survey stage. This paper describes how NUMO treats the geological environment model in the coastal area through the validation and demonstration program of geophysical prospecting in the CRIEPI's Yokosuka laboratory site. |
