Summary:The present invention relates to an apparatus for protection against radiation of inspection equipment for an internal structure of a calandria capable of performing visual inspection by inserting a measuring apparatus for inspecting an internal structure through a viewing port (VP) provided in a calandria vessel (10). The apparatus for protection against radiation inserting inspection equipment for an internal structure of a calandria into a VP provided in a calandria vessel (10) and ascending the inspection equipment in a vertical direction to inspect the internal structure comprises: a chamber (500) provided at an upper portion for the calandria vessel (10) in which the VP is located and having a transfer space of a rod unit (200) to which a measuring apparatus (100) is fixed at the lower end; and a vacuum source (610) connected to the chamber (500) to generate negative pressure. 본 발명은 칼란드리아 용기에 마련된 관측공을 통해 내부 구조물을 검사하기 위한 계측기기를 투입하여 육안 조사를 수행할 수 있는 칼란드리아 내부 구조물 검사장비의 방사선 피복을 방지하기 위한 장치에 관한 것으로, 칼란드리아 내부 구조물 검사기기를 칼란드리아 용기(10)에 마련된 관측공(VP)에 투입하여 수직방향으로 승강하여 검사하기 위한 시스템의 방사선 피폭 방지장치에 있어서, 상기 관측공(VP)이 위치하는 칼란드리아 용기(10)의 상부에 구비되어 계측기기(100)가 하단에 고정되는 로드부(200)의 이송구간에 마련되는 챔버(500)와; 상기 챔버(500)에 연결되어 부압을 발생시키는 진공원(610);를 포함한다.
