Abstract

The invention provides an LOCA simulation test device for fuel cladding, which comprises a sample clamping system, a high-temperature oxidation furnace system and a cold quenching system, wherein thehigh-temperature oxidation furnace system comprises a high-temperature oxidation furnace, the high-temperature oxidation furnace comprises a furnace chamber arranged in an axial direction and used forcontaining a sample for the fuel cladding, the top and bottom of the furnace chamber are respectively provided with a top opening and a bottom opening for conveying the sample; the cold quenching system comprises a cooling pool, wherein the cooling pool is positioned below a bottom opening and communicated with the bottom opening through a joint; the sample clamping system is positioned above theopening and is communicated with the top opening; the sample clamping system is used for suspending and fixing the sample and conveying the sample between the high-temperature oxidation furnace and the cooling pool. According to the invention, the chamber of the high-temperature oxidation furnace is arranged in the axial direction, the sample clamping system is positioned at the top opening of the furnace chamber, the cooling pool is positioned at the bottom opening of the furnace chamber, the sample can be hung and fixed and conveyed to the furnace chamber and the cooling pool through the sample clamping system, a high-temperature oxidation test and a thermal impact test of longer rod-like fuel cladding can be achieved.

Description

technical field [0001] The invention belongs to the technical field of nuclear safety control, and in particular relates to a fuel cladding LOCA simulation test device. Background technique [0002] In order to study the high-temperature steam oxidation performance of fuel cladding materials and the influence of resubmergence quenching on the cladding material properties after LOCA accidents in nuclear power plants, it is generally necessary to design a LOCA simulation test device. However, the existing device cannot realize the high-temperature oxidation test and thermal shock test on both sides of the longer rod-shaped fuel cladding; it cannot realize the high-temperature oxidation test and thermal shock test on the longer non-metallic rod-shaped fuel cladding. [0003] Therefore, there is a need for a fuel cladding LOCA simulation test device capable of performing high temperature oxidation tests and thermal shock tests on long rod-shaped fuel claddings.
