DRY MORTARS FOR CONSTRUCTION OF PROTECTIVE STRUCTURES AGAINST NEUTRONS WITH ENERGY OF 14.8 MeV
Pages 947-953
Subject: concrete for construction of protective structures from neutrons with energy of 14.8 MeV. When constructing protective structures from ionizing radiation in the buildings of nuclear facilities, special attention is given to the work quality and conformity assessment of the built structures to the project documentation requirements. Research objectives: the objective is to obtain the necessary data for verification of software programs for neutron-physical analysis of protective characteristics of concretes with different chemical composition. Materials and methods: in order to achieve the objectives, computational and experimental studies were carried out using a 14.8 MeV neutron generator, a spectrometric and dosimetric equipment complex, and the ANISN computational software package. Studies were carried out for two compositions of concrete. Results: the results of the performed studies showed satisfactory agreement between the computational and experimental data. Conclusions: the obtained results of computational and experimental studies will allow us to develop simple semi-empirical calculation methods that can be used in designing concrete compositions with the required protective efficiency from neutrons with energy of 14.8 MeV and in controlling the stability of chemical composition of dry concrete mixtures during their production and usage.
