Tritium water preparation device and method

Abstract

The invention relates to a tritiated water preparation apparatus and method, and belongs to the field of tritiated water preparation. The tritiated water preparation apparatus comprises a tritium storage metal tank, a first gas mass flow controller, an oxygen bottle, a second gas mass flow controller, a tritium and oxygen composite catalytic reactor, a cold trap, a tail gas collecting tank and a vacuum pump, the tritium storage metal tank communicates with the first gas mass flow controller, the oxygen bottle communicates with the second gas mass flow controller, the first gas mass flow controller and the second gas mass flow controller respectively communicate with the tritium and oxygen composite catalytic reactor, the tritium and oxygen composite catalytic reactor communicates with the cold trap, and the tail gas collecting tank and the vacuum pump respectively communicate with the cold trap. The tritiated water preparation method comprises working steps of the apparatus. The tritiated water preparation apparatus and the tritiated water preparation method realize rapid compounding of tritium and oxygen, recycling of tail gas tritium and obtaining of highly pure tritiated water, and have the characteristics of high preparation efficiency, low cost and high safety.

Description

technical field

[0001] The invention relates to the fields of chemical industry and nuclear technology and equipment, in particular to a device and method for preparing tritium water. Background technique

[0002] Tritium water (T2O) is an ideal non-partitioning tracer, which has important application value in water flooding development of complex fault-block oilfields. As a non-partitioning tracer, tritium water can not only dissolve in the injection fluid, but also migrate at the speed of the fluid, and has low detection limit, long-term chemical and radiochemical stability, no adsorption on the rock or wellbore surface, and no interaction with the reservoir fluid. Advantages of chemical reactions and isotope exchange. Through the calculation of tracer output, it can accurately calculate the parameters of high permeability zones or large pores between wells in oilfields, and can be widely used in water injection development of small fault block oilfields.
