Abstract

The invention provides a fuel cladding LOCA simulation test device, which includes a sample clamping system, a high temperature oxidation furnace system and a quenching system. The high temperature oxidation furnace system includes a high temperature oxidation furnace, and the high temperature oxidation furnace includes a sample for containing the fuel cladding and A furnace chamber arranged in an axial direction, the top and bottom of the furnace chamber are respectively provided with a top opening and a bottom opening for sample delivery; the quenching system includes a cooling pool, which is located below the bottom opening and connected to the bottom opening through a joint; the sample The clamping system is located above the top opening and communicates with the top opening. The sample clamping system suspends and fixes the sample and transports the sample between the high temperature oxidation furnace and the cooling pool. The furnace cavity of the high-temperature oxidation furnace of the present invention is arranged axially, the sample clamping system is located at the top opening of the furnace cavity, and the cooling pool is located at the bottom opening of the furnace cavity, and the sample can be suspended and fixed by the sample clamping system and transported to The furnace cavity and cooling pool can realize high temperature oxidation test and thermal shock test of longer rod-shaped fuel cladding.

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.
