Subcriticality control elements in a reactor system with an extended plasma source of neutrons with regard for temperature

Materials have been selected for the shim rods and burnable absorbers to compensate excessive reactivity of facility’s blanket part provide possibility control in conjunction with a plasma source neutrons. Burnable absorber is layer zirconium diboride (ZrB 2 ) thickness 100 μm applied surface fuel compacts. Boron carbide (B 4 C) installed helium flow channels used bring entire system into state k eff = 0.95 as rod material. Throughout its operating cycle, facility subcritical controlled using neutron flux from source. Verified codes, WIMS-D5B (ENDF/B-VII.0) MCU5TPU (MCUDВ50), well modern constants were calculations. The neutronic performance was simulated regard changes inner structure temperature microencapsulated compact materials caused by long-term irradiation migration fission fragments gaseous chemical compounds.
