Abstract
Zariadenie pre změnu polohy palivové] kazety sa vyznačuje tým, že vo vodiacej rú- re kazety je umiestnený piest, ktorého posuv je ovládaný hydraulicky.A device for changing the fuel cartridge is characterized in that a piston is disposed in the cassette guide, the feed of which is hydraulically controlled.
Description
Vynález sa lýka zariadenia pre změnu polohy palivovej kazety. '>« >The invention relates to a device for changing the position of a fuel cartridge. '>'>
Doteraz známe zariadenia pre změnu polohy palivovej kazety před kolimátoroih používané u nás i vo svete (NDR, USA] sú mechanicky zložité, změna polohy palivovej kazety je obtiažna. Zariadenie používané v našich podmienkach vyžaduje naviac stálu přítomnost žeriavu a' jeho obsluhy. Ďalšou nevýhodou je nutnost používať pri meraniach špeciálny bazén, alebo odtienený priestor nad bazénom skladovania vyhořených palivových kaziet.Previously known devices for changing the position of the fuel cartridge before collimators used in the Czech Republic and abroad (GDR, USA) are mechanically complicated, changing the position of the fuel cartridge is difficult. the necessity to use a special pool or shaded space above the pool for spent fuel assemblies.
Vyššie uvedené nevýhody sú odstránené zariadením pre změnu polohy palivovej kazety podía vynálezu, ktorého podstatou je, že vo vodiacej rúre kazety je umiestnený piest, ktorého posuv je ovládaný hydraulic· ky.The above disadvantages are overcome by the fuel cartridge positioning device of the present invention, which is based on the fact that a piston is disposed in the guide tube of the cartridge, the displacement of which is controlled hydraulically.
Hlavnou výhodou zariadenia podía vynálezu je přesné, jednoduché, spolehlivé a rýchle nastavenie meraného bodu palivovej kazety před kolimátorom. Pri vlastnom meraní nie je potřebný žeriav. Ďalšou výhodou je to, že ho je možné použiť v 1'ubovolnom bazéne so zabudovaným kolimátorom. Výhodou tohto zariadenia je i to, že počas všetkých manipulácii s vyhořenou kazetou je táto pod hladinou vody v bazéne, čím je zachovaná radiačná bezpečnost. Za výhodu je možné pokládat i to, že v případe zlyhania zariadenia pád meranej kazety je tímený hydraulikou a rýchlosť pádu sa rovná pracovnej rýchlosti posunu kazety. Nasta06 v-enie maximálnej hornej polohy palivovej kazety je- zaistené bezpečnostnými otvormi vo vodiacej rúre kazety.The main advantage of the device according to the invention is the accurate, simple, reliable and quick adjustment of the measured point of the fuel cartridge in front of the collimator. A crane is not required for the actual measurement. Another advantage is that it can be used in any swimming pool with a built-in collimator. The advantage of this device is that during all handling of the spent cartridge it is below the water level in the pool, thus maintaining radiation safety. It is also advantageous that in case of failure of the device the drop of the measured cassette is lowered by hydraulics and the drop speed is equal to the working speed of the cassette advance. Adjusting the maximum upper position of the fuel cartridge is secured by security holes in the cartridge guide tube.
’ Na prrpOjéiitíffi výkrese je schematické zobrazenie principu zariadenia podlá vynálezu, kde na obr. 1 je znázorněné zariadenie v podélnom řeze a na obr. 2 je znázorněný priečny rez podía roviny A—A.BRIEF DESCRIPTION OF THE DRAWINGS A schematic representation of the principle of the device according to the invention is shown. 1 shows a longitudinal section of the device, and FIG. 2 is a cross-sectional view taken along line A-A.
Na schematlckom zobrazení je kazeta 1, vodiaca rúra kazety .2, piest 3, přívod vody od čerpadla 4, přívod k ventilu 5, otvory vytyčujúce maximálnu hornú polohu piesta 6, závěs kazety 7.In the schematic illustration, the cassette 1, the cassette guide tube 2, the piston 3, the water inlet from the pump 4, the inlet to the valve 5, the openings indicating the maximum upper position of the piston 6, the hinge of the cassette 7.
Vodiaca rúra kazety 2 je upevněná na konzolách pri stene bazénu před ústim kolimátora pre meranie gama spektra vyhořeného paliva. V spodnej časti vodiacej rúry kazety 2 je otvor pre přívod vody od čerpadla 4 a otvor pre přívod k ventilu 5. V hornej časti vodiacej rúry kazety 2 sa nachádzajú otvory vytyčujúce maximálnu hornú polohu piesta 6. Vo vodiacej rúre kazety 2 je kazeta 1 položená na pieste 3. Piest 3 je hydraulicky ovládaný vháňaním vody čerpadlom, cez otvor-prívod vody od čerpadla 4, do priestoru pod piest 3, alebo jej vpúšťaním cez otvor- přívod Ik ventilu 5. Piest 3 vytláča aleho spúšťa kazetu 1 podlá potřeby. V případe, že spodný okraj piesta 3 je vyššie ako bezpečnostně otvory vytyčujúce maximálnu hornú polohu piesta 6, voda vháňaná čerpadlom uniká cez tieto otvory a nedojde k úplnému vytlačeniu kazety 1 z vodiacej rúry kazety 2.The cassette guide tube 2 is mounted on brackets at the pool wall in front of the collimator for measuring the gamma spectrum of the spent fuel. At the bottom of the cassette guide tube 2 is a water inlet opening from the pump 4 and a valve inlet port 5. At the top of the cassette 2 guide tube there are openings indicating the maximum upper position of the piston 6. In the cassette 2 guide cassette 1 is placed Piston 3. The piston 3 is hydraulically actuated by injecting water through the pump, through the inlet-water inlet from the pump 4, into the space below the piston 3, or through it through the inlet-inlet Ik of the valve 5. If the lower edge of the piston 3 is higher than the safety openings stating the maximum upper position of the piston 6, the water blown by the pump escapes through these openings and the cartridge 1 is not completely pushed out of the guide tube of the cartridge 2.
