“…Since 1989 the present facility for NTD-Si has been based on horizontal experimental channel HEC-4 with 150 mm diameter to allow us to dope ingots up to 125 mm in diameter and 750 mm in length using aluminum container diameter of 130 mm. The average thermal neutron flux in the channel is 4•10 12 cm -2 s -1 [5]. The uploading device of the facility/installation is surrounded by biological shielding made of heavy concrete so that safety conditions throughout ingots irradiation is fully provided (Fig.…”

“…The scope of such technologies is very wide. For example, the production of radioisotopes for medicine [1][2][3][4][5][6], radiation coloring of semiprecious stones for the jewelry industry [7][8][9][10], neutron transmutation doping of semiconductors for the electronics industry [11][12][13][14], and radiation treatment of seeds for the agricultural industry [15][16][17]. Nuclear and radiation technologies are implemented based on nuclear and electrophysical installations, in particular, on the basis of research reactors.…”

A nuclear reactor is a complex engineering and technical installation that generates radiation. Because of this, the experimental measurement of the radiation characteristics of a nuclear reactor is a difficult task, and in some cases technically impossible. The modern development of calculation codes and tools makes it possible to determine the radiation characteristics of a nuclear reactor with sufficient accuracy and reliability. Due to this, computational modeling of physical processes occurring in a nuclear reactor has become one of the main scientific research methods. The WWRK reactor is a multi-purpose research reactor with a large number of vertical and horizontal irradiation positions used for a wide range of scientific and applied problems. The irradiation position with the largest dimensions in the WWR-K reactor is the niche of experimental devices, which makes it possible to irradiate objects up to 1000 mm in diameter. This position is considered as a candidate for neutron transmutation doping of silicon ingots with a diameter of more than 200 mm. The article presents the radiation characteristics for the current and modernized configuration of the niche of the experimental devices of the WWR-K reactor. It is shown that the upgrade of the configuration leads to an improvement in the neutron characteristics in the irradiated position.
