Abstract

Abstract: The effect of high temperature(160~320)℃ on the helium leak detection results of TVS-2M fuel rod was investigated. The leak detector is used to analyze the change of leak rate value under different temperatures, and to explore whether high temperature affect the leak detection results and influencing factors. Through the experiment, the fastest temperature range and time of outgassing were obtained. The following conclusions are drawnthe main reason for the increase of helium leak detection results under high temperature is the venting of tvs-2m fuel rod; the fastest venting rate of TVS-2M fuel rod is at(200-220)℃; prolonging the residence time of TVS-2M fuel rod at(200~220)℃ can eliminate the effect of the increase of helium leak detection results caused by venting; when the holding temperature is at(200~220)℃ and the holding time is at(1~1.5)h, TVS-2M helium leak detection results of fuel rods are true and accurate.

Key words: nuclear reactor, fuel rod, high temperature effect, helium leak detection, outgassing
