The invention belongs to the technical field of level detection in the nuclear power industry and specifically relates to a device for measuring level under high temperature and high pressure irradiation environment. The device comprises a measuring probe, an electrical penetrating member, a dual coaxial cable and a detection circuit; two ends of the dual coaxial cable are respectively electrically connected with the detection probe and the detection circuit; a dual coaxial cable penetrating part is provided with an electrical penetrating member with the dual coaxial shielding structure. The invention applies the anti-hanging design to the high temperature and high pressure graphite dust environment, and proves through the test that the graphite bit dust adhesion is prevented from affecting the measurement result, and the material level under the high temperature, high pressure and irradiation environment is reliably measured.
Description
technical field [0001] The invention belongs to the technical field of material level detection in the nuclear power industry, and in particular relates to a device for measuring material level in a high temperature and high pressure irradiation environment. Background technique [0002] The R&D project of storage spherical tank material level gauge for absorption ball shutdown system of high temperature gas-cooled reactor was proposed by the Institute of Nuclear Research of Tsinghua University. switch alarm signal. High-temperature gas-cooled reactor nuclear power technology is an advanced nuclear power technology with independent intellectual property rights in my country. The reliable detection of the level gauge in the storage spherical tank of the high-temperature gas-cooled reactor absorption ball shutdown system is directly related to the normal operation of the nuclear power safety system. Requirements for the working environment in the storage spherical tank: the a...
