Embodiment Construction

[0025] S1: lithium beryllium oxide (Li 2 Bi 2 o 3 ) material preparation. Prepare quantitative high-purity lithium hydroxide (LiOH.H 2 O) and beryllium oxide (BiO), put them into the container according to the ratio of Li / Bi molecular molar ratio of 1 to 1.05, rotate and stir at room temperature (20°C to 30°C) for 20 to 24 hours to fully and evenly mix; after drying Put the gel into the sintering furnace, heat it to 1073-1100K in the air environment, sinter for 5-6 hours, and fully carry out the solid-phase reaction. The reaction formula is:

[0026] 2LiOH.H 2 O+2BiO→Li 2 Bi 2 o 3 +3H 2 o

[0027] After the furnace temperature dropped to room temperature, the samples were taken out for analysis;

[0028] S2: Sample analysis of lithium beryllium oxide material. Take an appropriate amount of lithium beryllium oxide sample and fully grind it into particles of 2-3 μm, and use XDR to analyze the grain composition of the sample, and the sample is composed of single-phase ...

Abstract

The invention discloses a preparation method of fusion reactor cladding neutrons and tritium breeding agent beryllium acid lithium pellets. The preparation method of the fusion reactor cladding neutrons and tritium breeding agent beryllium acid lithium pellets comprises the following steps: preparing a beryllium acid lithium material, representing, preparing beryllium acid lithium pellets with the diameter of 1mm, detecting performances, preparing lithium hydroxide and beryllium oxide raw materials at room temperature, putting into a container according to the proportion of 1 of Li/Bi molecule mole ratio, rotating and stirring for about 20 hours, mixing fully and uniformly, putting dried gel in a sintering furnace, warming to 1073K under an air environment, forging for 5 hours, and carrying out solid phase reaction fully; taking a beryllium acid lithium sample, grinding fully into particles, analyzing the formation of components by adopting XDR (external data representation; analyzing the Li/Bi mole ratio by adopting ICP-AES (inductively coupled plasma-atomic emission spectrometry). According to the invention, the problem that when lithium silicate or lithium titanate pellets are originally adopted as breeding agents, a plurality of layers of beryllium zone breeding neutrons are required to be arranged in a cladding is overcome, so that the utilization efficiency of breeding agents in a limited space of the cladding is improved extremely, and the fusion reactor tritium self-sustaining difficulty can be solved effectively.

Description

technical field [0001] The invention relates to a preparation method and an experimental system of an advanced neutron and tritium multiplication agent lithium beryllium oxide ball in a fusion reactor cladding, and belongs to the field of advanced nuclear reactor fuel research. Background technique [0002] Fusion energy is one of the potential effective ways for mankind to permanently solve energy problems. The construction and operation of the International Thermonuclear Experimental Reactor (ITER) has laid the foundation for the future construction of fusion power generation demonstration reactors. The high-energy neutrons (14.1 Mev) produced by the high-temperature plasma deuterium-tritium thermonuclear fusion of the fusion reactor enter the reactor and face the plasma component breeding cladding, and undergo a nuclear reaction with the tritium breeding material in the cladding to release huge energy, and at the same time breed fusion The fuel tritium needed by the stack...
