Modeling of new neutron filters with energies of 107 and 1.65 keV was performed. An improvement of the installation for measuring total neutron cross sections by the transmission method has been developed. The element base of the universal installation for measuring the spectra of gamma for neutron capture has been updated. The possibility of studying the neutron capture cross sections for Hf and U nuclei with high accuracy is analyzed. Rules for entering spectra into the international experimental database CSISRS/EXFOR were developed. Algorithms was developed and software products for the preparation of data from neutron spectra after interference neutron filters was created. 9 blocks of data with spectra were entered into the international experimental database CSISRS/EXFOR. Compilation of experimental data obtained by Ukrainian scientists into the international experimental database CSISRS/EXFOR for incident neutrons (30 data sets), gamma quanta (140 sets) and charged particles of 413 data sets) were done. An updated English version of the Ukrainian Nuclear Data Center website has been created. Assistance was provided in obtaining and preparing nuclear data from the international experimental database CSISRS/EXFOR and ENDL at the request of nuclear data users. The possibility of obtaining software products from the database of computer programs at NEA Data Bank Computer Program Services (Paris, France) for the staff of the INR has been restored. Textual information on 2241 works on nuclear topics (nuclear theory, particle physics, plasma, materials science, nuclear reactors, ecology, effects of radiation on living organisms and biological materials) published in Ukraine was sent to the IAEA for inclusion in the INIS database.
