Abstract

Zariadenie je určené k tieneniu povrchu nátrubkov jádrových reaktorov pri kontrole a opravě. Kuželový tanier tvaru zrezaného ikužela má plášť vyložený tieniacimi blolkmi okrem miesta, kde je v plášti štrbina. Pootáčaním plášťa štrbina odkrývá len nutná časť povrchu nátrubku.The device is intended for shielding the surface of the nozzles of nuclear reactors during inspection and repair. The conical plate in the shape of a truncated cone has a shell lined with shielding blocks except for the place where there is a slot in the shell. By rotating the shell, the slot exposes only the necessary part of the nozzle surface.

Description

Vynález sa týká zariadenia pre tienenie nátrubkov jádrových reaktorov.BACKGROUND OF THE INVENTION The present invention relates to a device for shielding core reactor sleeves.

Doteraz známe zariadenie používané pre tento účel při kontrole a opravě nátrubkov je tvořené válcovým tienením, spuštěným do nádoby reaktora, ktoré má oproti nátrubku otvor vačší ako nátrubok. Personál je vystavený účinkom žiarenia, ktoré je úměrné ploché otvoru.The prior art device used for this purpose in the inspection and repair of the sleeves is formed by a cylindrical shield, lowered into the reactor vessel, which has an opening larger than the sleeve opposite the sleeve. The staff is exposed to radiation that is proportional to the flat hole.

Vyššie uvedený nedostatok je odstránený zariadením podlá vynálezu, ktorého podstatou je kuželový tanier tvaru zrezaného kužela, ktorý má plášť vyložený tieniacimi blokmi okrem miesta, kde je v plášti výřez. Pootáčaním plášťa oproti povrchu nátrubku štrbina poodkrývá len nutnú časť nátrubku. Za účelom montáže je zariadenie tvořené montážnymi celkami, a to centrálny hriadel ukončený čapom s kotevnými doskami, kuželavý tanier, tieniace bloky, matica s pákou talk, aby pre ich montáž postačovali 1 až 2 pracovníci.The aforementioned drawback is eliminated by the device according to the invention, the essence of which is a frusto-conical conical plate having a casing lined with shielding blocks in addition to where a cutout is present in the casing. By rotating the jacket against the mouthpiece surface, the slit only reveals the necessary part of the sleeve. For the purpose of assembly, the device consists of assembly units, namely the central shaft terminated by a pin with anchor plates, the conical plate, the shielding blocks, the nut with the lever lever, so that 1 to 2 workers are sufficient for their assembly.

Hlavná výhoda zariadenia spočívá v znížení radiaonej záťaže pracovníkov pri opravě a kontrole nátrubkov.The main advantage of the device is that it reduces the radioactive burden on workers when repairing and inspecting sleeves.

Na výkrese je znázorněný pozdížny rez zariadením.In the drawing, a cross-sectional view of the device is shown.

Kuželový tanier 4 tvaru zrezaného kužela, ktorý má povrch vyložený tieniacimi blokmi 5 okrem miestá, kde je v povrchu výřez 6, je otočné uložený na čapě 3 centrálneho hriadela 1, ktorý je upevněný v kotevných doškách 2.The frusto-conical cone plate 4 having a surface lined with shielding blocks 5, except where the cutout 6 is in the surface, is pivotally mounted on the pivot 3 of the central shaft 1, which is fixed in the anchorage 2.

Funkcia zariadenia spočívá v tom, že kuželový tanier 4 pootáčaním odkrývá výrezom 6 v plášti len tie miesta, ktoré sú nutné k prehliadke alebo opravě nátrubku 9, pričom tieniace bloky 5 ostatně časti zakrývajú. V potrebnej poloihe možno kuželový tanier poistiť proti pootočeniu maticou 7 s pákou 8. Zariadenie sa skládá z montážnych celkov, a to centrálny hriadel 1 ukončený čapom 3, kuželový tanier 4, tieniace bloky 5, matica 7 s pákou 8.The function of the device is that the tapered plate 4 revolves only by rotating the cut-out 6 in the housing, which is necessary for the inspection or repair of the sleeve 9, while the screening blocks 5 cover the parts. In the required position, the tapered plate can be locked against rotation by nut 7 with lever 8. The device consists of assembly units, namely central shaft 1 terminated by pin 3, conical plate 4, shielding blocks 5, nut 7 with lever 8.
