Abstract

The invention relates to a method for simulating nuclear materials in a molten salt reactor (MSR). The method comprises following steps: providing a device for simulating nuclear materials in a moltensalt reactor (MSR); hanging a nuclear material sample on the bottom of an elevating device, forming a simulated system that is isolated with the external environment; starting a high temperature furnace to heat molten salts to a temperature of 400-650 DEG C, soaking the nuclear material sample in liquid molten salts; automatically lifting the nuclear material sample out from the molten salts by the elevating device; introducing mixed gas into the tank through an air inlet pipeline, and interacting the mixed gas with a thin salt membrane to carry out a high temperature test; wherein the mixedgas is Ar-HF, Ar-HF-O2, Ar-HF-CO2-CO, or Ar-HF-CO2-H2. According to the simulation method, the safety is high, the elevation can be automatically controlled, furthermore, simulation and monitoring indifferent environments can be carried out, and the method has a wide application prospect.

Description

technical field [0001] The invention relates to the field of molten salt, more particularly to a method for simulating nuclear materials in a molten salt reactor. Background technique [0002] Since the molten salt reactor uses lithium-fluorine salt as the primary circuit coolant, a large amount of tritium will be produced after neutron irradiation in the reactor. According to the relevant research on the molten salt reactor by the Oak Ridge National Laboratory in the United States, the tritium produced in the molten salt reactor mainly exists in the form of tritium fluoride (TF) and HT. The highly corrosive TF is easy to corrode the reactor loop pipe, reducing the material Tritium control has become a key scientific and technical issue in molten salt reactor research. [0003] Obviously, the realization of tritium control requires the study of the interaction between tritium in molten salt and nuclear materials, which requires the simulation of nuclear materials in molten ...
