Research methods are physical and mathematical modulation in programs using the Monte Carlo code in the MCNP6 program and physical modeling in the Serpent program. The most important results are: Modeling of the transfer process of relevant particles (neutrons and photons) in the proposed fiber-concretes was carried out in the MCNP6 and Serpent programs for various concrete compositions and sources of radioactive radiation. The calculation of neutron and gamma radiation dose rates and rates was performed in the Serpent program. The results of simulation of the obtained results were analyzed. Modeling of the passage of neutron radiation in concrete composites was carried out using the Monte Carlo code MCNP6. It is shown that the addition of basalt-boron fiber to concrete improves the protective properties of concrete against neutron radiation. An industrial technology for creating basalt-boron fiber, a material for reinforcing concrete, has been developed, which will improve its mechanical characteristics, reduce the level of microcracks and, as a result, increase durability and significantly improve the protective characteristics of concrete against neutron radiation.
