Embodiment Construction

[0022] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0023] A kind of UF 6 The measuring container of the gas uranium abundance online monitoring device, such as figure 1 As shown, the measuring container is a cylindrical structure, UF 6 The gas enters the container through the inlet pipe 1 and flows out through the outlet pipe 2, and the detector 3 is placed at the bottom of the container. This embodiment preferably adopts a Marlin cup structure, such as figure 2 As shown, the detector 3 is placed in the inner cup of the container. The measuring container is mainly composed of a housing, an inlet pipe 1, an outlet pipe 2, and a deflector 8. The deflector 8 divides the container into a continuous flow channel in the housing. The inlet pipe 1 is located at the inlet end of the channel, and the outlet pipe 2 is located at the Channel exit port.

Abstract

The invention discloses a measuring container of an online detecting device for UF6 gas uranium abundance, wherein the measuring container is of a cylindrical structure, and comprises a shell, an inlet pipe, an outlet pipe and a guide plate; the guide plate divides the container into a continuous flowing channel in the shell; and the inlet pipe is located at an inlet end, and the outlet pipe is located at an outlet end. The measuring container provided by the invention is capable of online and real-time detecting gas uranium abundance, and has the characteristics of simple structure, high probing efficiency and no gas retention.

Description

technical field [0001] The invention relates to the technical field of nuclear material analysis, in particular to a UF 6 The measuring container of the gas uranium abundance online monitoring device. Background technique [0002] A uranium enrichment plant is a nuclear facility that conducts uranium enrichment activities, and is one of the key objects of arms control inspection and safeguard supervision. Uranium enrichment plants use mass spectrometers to monitor UF in pipelines 6 gas 235 U abundance, this technology has high precision, but the operation is complicated, the cost is high, the analysis period is long, and professionals are required. [0003] At present, the United States and Russia have mainly carried out research on related technologies in the world, and there has been no research on related technologies in China. On-line uranium abundance technology consists of two parts: total uranium measurement and UF 6 in gas 235 Measurement of U content. 235 The...
