Embodiment Construction
[0037] Attached below figure 1 The present invention will be described in further detail.
[0038] Example design: 200kW medical isotope production reactor saving uranium fuel
[0039] The core production structure of the reactor mainly includes:
[0040] Flat-bottomed cylindrical stainless steel core container 1 with core material liquid 3: UO 2 (NO 3 ) 2 And the air cavity 4 above and the core material liquid 3 radially divided into inner and outer zones. The inner zone is arranged with control rod duct 2 including two safety rod ducts, two automatic adjusting rod ducts and two compensation rod ducts, each of which is control rod The tube is sealed and welded to the upper cover and lower bottom of the core vessel 1, the inside of each control rod tube is water, and the outside of the control rod tube is connected to the fuel solution UO 2 (NO 3 ) 2 In contact, the safety rod, automatic adjustment rod and compensation rod installed in the control rod duct 2 can be moved up and dow...

The invention discloses a medical isotope production reactor with uranium fuel saving. The main structural characteristics of the medical isotope production reactor are that a concentrated liquid overflow port is added in an acidication tank, a liquid discharge quantity indication tank is connected through a pipeline, the bottom pipeline of the liquid discharge quantity indication tank is connected to the feed liquid discharge pipeline of a core vessel, from an acidication tank concentrated liquid overflow port pipeline, by way of a liquid discharge quantity indication tank, the washing water discharge pipeline of the liquid discharge quantity indication tank, the feed liquid discharge pipeline connected to the core vessel, after accessing and washing a medical isotope extraction column and discharging washing water into a storage tank, a washing water pipeline system of acidication tank washing extraction column is formed. By using the system, after starting and stopping the reactor to carry out isotope extraction in each time, the feed liquid is stored in the storage tank, then by using the system, the washing water with remaining uranium after washing the extraction column is discharged into the storage tank, the washing water and the feed liquid with isotope extraction in the tank are mixed, in a next time of starting the reactor, dilute feed liquid is concentrated to the initial fuel concentration of a previous time of reactor starting, and a lot of uranium fuels are saved in the life cycle of 20 years of the reactor.
Description
Technical field [0001] The invention relates to a "water boiler" type medical isotope production reactor technology, in particular to a method for saving uranium fuel in a medical isotope production reactor. Background technique [0002] The technology of medical isotope production reactor is developed from the "water boiler" type solution reactor. Due to the relatively small scale and low power of the "water boiler" solution reactors, the amount of extracted medical isotopes is very limited, and most of the "water boiler" solution reactors in the world are shut down due to various reasons such as equipment aging and process technology. At present, there is no large-scale dedicated solution fuel medical isotope production reactor in the world. [0003] The medical isotope production reactor that saves uranium fuel applied in this case is designed to operate for 24 to 48 hours each time, and then shut down for cooling. After cooling, the material liquid is passed through a medical ...
