Problems solved by technology

However, there are potential safety hazards in this design. During the whole process of transferring samples to the fume hood for analysis, the operator will still receive a certain dose of radiation. Moreover, due to the poor sealing performance of the fume hood, it is easy to cause the leakage of radioactive atmosphere, and the reliability is poor.

Abstract

The invention discloses analysis equipment and an analysis system for a spent fuel reprocessing plant. The analysis equipment comprises a sample receiving and transmitting shielding box chamber; the pretreatment shielding box chamber is connected with the sample receiving and sending shielding box chamber through a first channel, the side wall of the pretreatment shielding box chamber and the side wall of the sample receiving and sending shielding box chamber which are connected with the first channel are in sealed connection, and a first cover door used for opening and closing is arranged in the first channel; the analysis shielding box chamber is connected with the pretreatment shielding box chamber through a second channel, the side wall, connected with the second channel, of the pretreatment shielding box chamber and the side wall of the analysis shielding box chamber are connected in a sealed mode, and a second cover door used for opening and closing is arranged in the second channel. The equipment meets the requirement of personnel for safe operation, reduces unnecessary sample circulation, simplifies personnel operation, improves analysis efficiency, prevents electronic components of instruments from being damaged by radiation, and is convenient to overhaul and maintain.

Description

technical field [0001] The invention belongs to the technical field of nuclear fuel reprocessing, and in particular relates to an analysis equipment and analysis system of a spent fuel reprocessing plant. Background technique [0002] The analysis laboratory of the post-treatment plant mainly analyzes various materials in the post-treatment process and the three-waste treatment process, providing timely and accurate analysis results for process operation. Analytical laboratories undertake a large amount of sample analysis, including samples with high, medium, and low radioactive levels. There are many analysis items and analysis positions. Usually, the same sample needs to complete multiple analysis tasks, and the types of instruments involved are also very wide. In addition, due to the strong radioactivity and toxicity of the samples in the post-processing plant, personnel cannot directly contact them. The analysis operation needs to be carried out in a shielded box room (h...
