（産業上の利用分野）
本発明は、現在原子力発電所で定検実施時に照射された
燃料集合体の再装荷の可否の観点から、実施している燃
料集合体の外観検査方法に関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to the reloading of fuel assemblies currently being carried out at nuclear power plants from the viewpoint of whether or not fuel assemblies that have been irradiated during periodic inspections can be reloaded. This invention relates to an appearance inspection method.
（従来の技術）
燃料集合体の外観検査には、従来がら水中テレビが使用
されている。水中テレビ検査は再装荷予定の燃料集合体
を全て検査することもあり、原子力発電所の定検におい
て燃料取出、燃料検査の工程はクリティカルになってい
る。(Prior Art) Underwater televisions have traditionally been used for visual inspection of fuel assemblies. Underwater TV inspections sometimes involve inspecting all fuel assemblies scheduled for reloading, making the fuel removal and fuel inspection processes critical during regular inspections at nuclear power plants.
原子力発電所ではその稼働率向上の観点から定検短縮が
叫ばれており、そのために、は水中テレビ装置による外
観検査時間の短縮が必要となる。しかしながら従来の水
中テレビ検査装置は７面型もしくは２面型であり、７体
の検査時間が長く、またμ面を検査するために燃料集合
体を回転させる機構が必要となってくる。At nuclear power plants, there is a need to shorten periodic inspections in order to improve their operating rates, and for this purpose it is necessary to shorten the time required for visual inspections using underwater television equipment. However, conventional underwater TV inspection apparatuses are of a seven-sided or two-sided type, which takes a long time to inspect seven bodies, and requires a mechanism for rotating the fuel assembly in order to inspect the μ plane.
（発明が解決しようとする問題点）
定検実施時における燃料検査工程に要する時間を短縮す
ることを目的とするものである。(Problems to be Solved by the Invention) It is an object of the present invention to shorten the time required for a fuel inspection process during periodic inspection.
（問題点を解決するための手段）
燃料検査の一つとして水中テレビによる外観検査があり
、現状では７面型もしくは２面型であるが、それに代わ
って弘面型の水中テレビを使用することによって大幅な
検査時間の短縮となる。(Means for resolving the problem) One of the fuel inspections is visual inspection using an underwater television.Currently, it is a 7-panel or 2-panel type, but it is recommended to use a Hiromen-style underwater television instead. This results in a significant reduction in inspection time.

ダから燃料を引き上げる際に、同時に燃料の外観検査を
する方法を併用する。Furthermore, as a method to shorten the inspection time the most, a q solid underwater TV is fixed near the appender of the fuel transfer canal in the fuel handling building, and when the spent fuel bit crane is pulling up the fuel from the appender, the fuel is removed at the same time. Use in conjunction with the method of visual inspection.
この方法によれば外観検査のためだけに必要な時間を大
巾に短縮してしまうことが可能である。According to this method, it is possible to greatly reduce the time required just for visual inspection.

ｑ固型水中テレビを燃料集合体の表面検査に使用するの
で、燃料を回転する機構、テレビカメラの駆動機構も不
要になる。(Function) q Since the solid underwater television is used to inspect the surface of the fuel assembly, a mechanism for rotating the fuel and a driving mechanism for the television camera are also not required.
（実施例） 本発明の実施状況を第３図に示して説明する。(Example) The implementation status of the present invention will be explained with reference to FIG.
燃料集合体１は格納容器１０側からマニプレータクレー

燃料移送キャナル１１を通って燃料取扱建屋１２側へ移
送される。その後燃料取扱建屋１２側のアペンダ２上に
移されて、アペンダ２の回転により直立状態にされる。The fuel assembly 1 is transferred from the containment vessel 10 side to the fuel handling building 12 side through the fuel transfer canal 11 in a horizontal state by a manipulator crane 40 and an appender 2 having a rotation function. Thereafter, it is moved onto the appender 2 on the side of the fuel handling building 12, and is brought into an upright state by rotating the appender 2.
この状態で燃料取扱クレーン１３で燃料集合体１を吊り
上げて燃料保管ラック１４へ運び保管される。３０１１
イチ困シをｆ゛厘料フ０−ルて一青る。In this state, the fuel assembly 1 is lifted up by the fuel handling crane 13 and transported to the fuel storage rack 14 for storage. 3011
If you are in trouble, please fill out the fee.
従来は外観検査などはこの後再び燃料集合体１を保管ラ
ック１４から取り出して検査装置を設けである場所まで
クレーンで運んで検査を行っていた。Conventionally, for external inspection, etc., the fuel assembly 1 was taken out from the storage rack 14 again and transported by crane to a location where an inspection device was installed for inspection.

時に外観検査を行うようになっている。In the present invention, as shown in FIG.
By providing the fuel assembly 1 adjacent to the appender 2, it is possible to perform an external appearance inspection while taking out the fuel assembly 1 from the appender 2.

る。(Effect of the invention) Since the visual inspection of the t-plane of the fuel assembly is carried out simultaneously while pulling it up from the appender, it goes without saying that the inspection time is greatly shortened, and the inspection surface of the fuel assembly can be seen by a television camera. There is no need to install a rotation mechanism to orient the camera.
