Description
Przedmiotem wynalazku jest sposób wytwarzania molibdenu - 99 z uranu — 235. Molibden — 99 znajduje szerokie zastosowanie glównie w medycynie jak równiez w badaniach naukowych.The present invention relates to a method of producing molybdenum-99 from uranium-235. Molybdenum-99 is found widely used mainly in medicine as well as in scientific research.
Opisany w BNL Mannual of Izotope Production Processin Use at BNL (USAEC Rep. BNL-864 August 1964) sposób wytwarzania molibdenu —99 z uranu — 235 polega na napromienianiu w rdzeniu reaktora jadrowego tarczy w postaci stalej, gdzie uran — 235 wystepuje jako stop z aluminium. Po napromienieniu tarcze zawierajaca molibden — 99 w mieszaninie z produktami rozszczepienia uranu rozpuszcza sie, a nastepnie z otrzymanego roztworu wydziela sie molibden — 99 metodami chromatograficznymi. Inny sposób otrymywania , produktów rozszczepienia podany jest w opisie patentowym RFN Nr 1028704, w którym napromienianiu w reaktorze poddaje sie zawiesine dwutlenku uranu w wodzie, a wytworzone w procesie napromieniania produkty rozszczepienia uranu wydziela sie na sorbencie.Described in BNL Mannual of Izotope Production Processin Use at BNL (USAEC Rep. BNL-864 August 1964) the method of producing molybdenum -99 from uranium-235 consists in irradiation in the reactor core a nuclear shield in the form of a solid, where uranium - 235 exists as an alloy with aluminum. Shields after irradiation containing molybdenum - 99 in a mixture with uranium fission products, dissolves, and then the molybdenum-99 solution is separated from the solution obtained by chromatographic methods. Another way to get it fission products is described in the German patent specification No. 1028704, in which the irradiation in the reactor, a suspension of uranium dioxide in water is subjected to, and produced in the irradiation process the fission products of uranium are separated on the sorbent.
Sposób wedlug wynalazku polega na tym, ze jako material tarczowy poddawany napromienianiu w reaktorze jadrowym stosuje sie wodny roztwór soli uranu — 235, korzystnie roztwór siarczanu lub azotanu uranylu, a tarcze po wydzieleniu Mo — 99 zawraca sie ponownie do napromieniania w reaktorze jadrowym.The method according to the invention consists in being the target material to be irradiated the nuclear reactor uses an aqueous uranium salt solution-235, preferably a sulfate or nitrate solution uranyl, and the targets after Mo-99 separation are recycled back to irradiation in the nuclear reactor.
Zaleta sposobu wedlug wynalazku jest wyeliminowanie czasochlonnej i stwarzajacej dodatkowe zagrozenie obróbki chemicznej wysokoaktywnej tarczy uranowej co mialo miejsce w dotychczas stosowanych sposobach.The advantage of the method according to the invention is that it is time-consuming and does not pose an additional risk the chemical treatment of the highly active uranium target, which has taken place in the methods used so far.
Ponadto, mozliwosc wielokrotnego wy korzystania tej samej tarczy w sposób znaczny zmniejsza ilosci wysokoaktywnych odpadów promieniotwórczych w procesie. Przyklad wykonania sposobu wedlug wynalazku: Roztwór wedlug siarczanu uranylu zawierajacy 10 g/l wzbogaconego uranu w uran — 235 oraz kwas siarkowy wielkosci 0,5 m/l poddaje sie procesowi napromieniania w rdzeniu reaktora jadrowego wciagu 120 godzin.In addition, the ability to use the same blade multiple times significantly reduces the amount high-level radioactive waste in the process. An example of the implementation of the method according to the invention: Uranyl sulphate solution containing 10 g / l of enriched uranium in uranium-235 and sulfuric acid size 0.5 m / l is subjected to the irradiation process in the core of a nuclear reactor within 120 hours.
Napromieniona tarcze pozostawia sie przez 24 godziny celem wygasniecia krótkozyciowych produktów rozszczepienia uranu — 235, a nastepnie z roztworu wydziela sie molibden — 99 na drodze wymiany jonowej znanym sposobem. Tarcze zawraca sie ponownie do napromieniania w reaktorze.2 103 638The irradiated target is left for 24 hours to extinct short-lived products fission of uranium - 235, and then molybdenum - 99 is separated from the solution by ion exchange known way. The targets are recycled back to the irradiation in the reactor. 2 103 638
