Abstract

The invention belongs to an apparatus for nuclear reactor spent fuel element damage detection, specifically an underwater sipping apparatus for the spent fuel element damage detection. The apparatus comprises a sipping container, a quick coupling, air inlet pipes, exhaust pipes, air inlet valves, air release valves, drainage pipes and the like. A main material of the apparatus is stainless steel.According to the apparatus provided by the present invention, batch radioactive gas samples required by the spent fuel element damage detection can be collected in a short time so as to provide high detection efficiency.

Description

technical field [0001] The invention relates to a damage detection device for nuclear reactor spent fuel elements, in particular to an underwater sipping device for detecting damage to nuclear reactor spent fuel elements. Background technique [0002] In the damage monitoring of spent fuel elements of nuclear reactors, it is necessary to monitor the presence or absence of spent fuel elements 85 The overflow of radioactive gases such as Kr is one of the effective methods to judge whether the spent fuel element is damaged. Wherein the collection of spent fuel elements spilled after damage 86 There are many kinds of devices for radioactive gases such as Kr. At present, all devices of this type package a single or multiple spent fuel elements in a lead-shielded container, use underwater loading, and lift them to the water for capping operation. By heating the gas or water medium in the container, and then collecting the gas released from the breach of the spent fuel element 8...
