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.
