身が熱応力その他の理由で位置ずれをおしたり・又ＣＲ
Ｄ自動交換装置の位置ずれに対して対応ができず、最終
確認を目視に頼っていた。In conventional CRD replacement work, the automatic CHD replacement device was positioned relative to the CRD installation position, so the CRD itself could be misaligned due to thermal stress or other reasons.
It was not possible to deal with misalignment of the automatic exchange device D, and the final confirmation relied on visual inspection.
そのため、作業時間及び作業員の被曝量の増大を招いて
いた。This resulted in an increase in working hours and the amount of radiation exposure for workers.
本発明の目的は１作業′性が悪く作業幀の被曝量が多い
ＣＲり交換作業の自動化を可能とすることにある。An object of the present invention is to enable the automation of CR replacement work, which is difficult to perform and involves a large amount of radiation exposure in the work area.

たＣＲＤ交換装置によるＣＲり交換作業を自動的に行う
ことを考案する。In order to automate the CRD replacement work,
A one-touch target is attached to the lower flange surface of D, and a CRD replacement work using pattern recognition is automatically performed using the target.
以下、本発明の一実施例を説明する。 An embodiment of the present invention will be described below.
