Embodiment Construction

[0048] combined with figure 1 Describe in detail the core content involved in the design of a 200kW Medical Isotope Production Reactor (MIPR) by canceling the core compensating rods and simplifying the core structure of the present invention.

[0049] The core production structure of the 200kW medical isotope production reactor without compensation rods mainly includes:

[0050] Built-in core liquid UO 2 (NO 3 ) 2 The flat-bottomed cylindrical stainless steel core vessel 1 contains the core feed liquid 3 and the upper gas chamber 4. The core feed liquid 3 is radially divided into inner and outer areas, and the inner area is arranged with control rods 2: including two automatic adjustment rod guide tubes and Two safety rod conduits, the four conduits of these two types of control rods are sealed and welded to the upper cover and lower bottom of the core vessel 1, the conduits are filled with water, and the outer wall of the conduits is in contact with the fuel solution UO 2...

Abstract

The present invention discloses a medical isotope production reactor without a compensation rod and a method of continuously operating to compensate a reserve reaction loss. The reactor does not need a compensation rod, through the increase of the concentration of reactor core solution uranium-235 in operation or a frequent feeding method of maintaining the reactor core solution uranium-235 to be unchanged basically, the reserve reaction of the reactor is improved, the function of the compensation rod is substituted, a reactor core structure and a control system are simplified, and the initial loading amount of uranium is reduced. Since a self concentrated liquid overflow port pipeline is added to a reactor compensation acidication tank, by way of a liquid discharge quantity indication tank, the washing water discharge pipeline of the tank and a feed liquid discharge pipeline connected to a core vessel, after accessing and washing an extraction column, the washing water acesses a storage tank from the washing water discharge pipeline of the extraction column, the washing water pipeline system of an acidication tank composite water washing extraction column is formed, abandoned uranium is recycled, and a large amount of uranium materials is saved.

Description

technical field [0001] The invention relates to the field of "water boiler" type solution nuclear reactor. It specifically relates to the medical isotope production reactor that cancels the core compensation rod, and how to compensate for the loss of its backup reactivity to maintain the normal operation of the core. Background technique [0002] So far, no high-power "water boiler" type solution nuclear reactor for medical isotope production has been built in the world. The 200kW Medical Isotope Production Reactor (MIPS) in the United States is being designed, but the project has been suspended according to current information. my country's 200kW Medical Isotope Production Reactor (MIPR) began research and development in 1997. Due to various reasons, it took a long time. The research on the type and quantity of core control rods still stays on the solid fuel assembly reactor. [0003] The study found: [0004] For solid nuclear fuel assembly reactors, there are five majo...
