Abstract

UREDJAJ ZA POKRETANJE DVA SNOPA VERTIKALNO POKRETLJIVIH SIPKI NAROCITO REGULACIONIH SIPKI U ISTOM GORIVNOM SKLOPU U JEZGRU NUKLEARNOG REAKTORA, koji ima zatvoreni sud sa fluidom pod pritiskom u kome se kupa jezgro reaktora, sastavljeno od sklopova obrazovanih od snopova gorivnih sipki postavljenih vertikalno i u koje se za vreme rada reaktora uvlace snopovi, pri cemu jedan snop ima sipke koje apsorbuju neutrone i obezbedjuju regulisanje reaktora vertikalnim pomeranjem kojim se menja stepen uvlacenja apsorbentnih sipki, a drugi snop ostaje potpuno uvucen u sklop tokom samo jednoga dela ciklusa rada reaktora, nezavisno od pomeranja prvoga snopa, svaki snop je sastavljen od skupa medjusobno paralelno postavljenih sipki koje su spojene sa jednim delom za fiksiranje, mehanizam koji se sastoji od dve upravljacke sipke 2, 3 velike duzine od kojih je jedna spojena sa prvim a druga sa drugim snopom, pokretljivo su postavljene unutar jedne zaptivne caure 1 koja je u vezi sa unutrasnjim volumenom suda, jedan mehanizam 27, 28, 29, 30, 34 za drzanje i za kontrolisano vertikalno pomeranje upravljacke sipke 2 prvoga snopa unutar zaptivne caure, i uredjaj za rastavljivo spajanje svakoga od dva snopa sa odgovarajucom upravljackom sipkom 2, 3 naznacen time, sto se na gornjem delu kosuljice upravljacke sipke (2) prvoga snopa postavljene hvataljke (41) u prstenasti prostor (4), sto se na njih naslanja pokretna kosuljica (45) klizno postavljena na kraju upravljacke sipke (2), sto je izmedju sipke (2) i kosuljice (45) smestena opruga (46), sto gornji naslon (60) kosuljice (45) naleze na sediste (61) caure (1), sto je upravljacka sipka (3) postavljena koaksijalno unutar upravljacke sipke (2) i celom svojom duzinom ima jedan prosireni deo (3b) sa zaptivnim segmentima (50) i jedan zljeb (53), sto je na ispustu (54) postavljen naslon (55) na koji naleze sediste (56) na sipki (2), pri cemu je na gornjem delu caure (1) postavljen ventil (65) za dekompresiju. Prijava sadrzi jos 2 patentna zahteva.
