DEMOLITION METHOD FOR DAMAGED REACTOR CORE
PROBLEM TO BE SOLVED: To provide a demolition method for a reactor capable of performing without filling the inside of a reactor containment with water.SOLUTION: A demolition method comprises: placing a pier 31, for lowering work apparatuses into a reactor, on a work floor 30 in the upper part of the reactor; fixing connection tubes 3 at the pier 31 with fixing mechanisms; lowering various work apparatuses through the connection tubes 3 and fixing the work apparatuses with work apparatus fixing mechanisms placed respectively at ends of the connection tubes 3; and performing demolition work with the work apparatuses in this state and continuing the demolition work by adding the connection tube 3 sequentially as the depth of work increases.SELECTED DRAWING: Figure 5
【課題】格納容器内に水を満たさずに施工できる原子炉解体方法を提供する。【解決手段】原子炉上部の作業フロア３０に作業器機を原子炉内部に釣り下ろすための桟橋３１を設置する。接続管３を固定機構により桟橋３１に固定する。接続管３を貫通して各種作業器機を釣り下ろし、それぞれの接続管３の先端に設置された作業器機固定機構により作業器機を固定する。この状態で作業機器により解体作業を行い、作業深度が深くなるにつれ順次接続管３を継ぎ足して解体作業を継続する。【選択図】図５
