[en] In a repository for spent fuel a shaft hoisting system is to be built for a transport unit (waste package and vehicle) with a total weight of 85 t. At present no suitable hoisting equipment for 85 metric tons is available anywhere in the world. To establish its technical maturity a preliminary design was carried out. More than 100 shaft hoisting facilities in operation were analyzed in a 'reference study'. The result is that nearly all main components of the shaft hoisting facility can be referred to facilities in operation. Only very few components with special requirements for a repository must be built up in a prototype scale and tested to establish its maturity

[en] The ICARUS T600 detector is in operation at the Gran Sasso underground laboratory. High quality cosmic ray and CNGS beam events are being collected and analyzed.

[en] The realization of a 600 tons liquid argon (LAr) TPC represents the first step of the ICARUS project. The principal aim of this detector to be run into the Gran Sasso Laboratories, will be a detailed analysis of the atmospheric and solar neutrinos fluxes with very low and well controlled experimental systematics. The final goal of the projects is to reach, by addition of other 600 tons modules, a sensitive mass of the order of 5000 tons to study the matter stability up to nucleon lifetimes of the order of 10³⁴ years and to search for long baseline neutrinos oscillations with a neutrino beam from CERN.

[en] The article presents some reasons for the lagging of domestic mining engineering from foreign competitors, substantiates the need to form a new promising technological paradigm in the field of formation and development of underground space. A new systematic approach to the development of geotechnics and geotechnologies is proposed, which allows for creation of prerequisites for formation of a new technological structure and Russia’s breakthrough into leading positions in the field of geotechnology and mining engineering.

[en] We report the latest results of the search for magnetic monopoles with the MACRO detector at Gran Sasso. No candidate events have been observed and flux upper limits for an isotropic flux of magnetic monopoles are established at the level of the Parker bound. (author)

[en] Jinping Underground Nuclear Astrophysics Experiment (JUNA) will take the advantage of the ultra-low background in China Jinping Underground Laboratory (CJPL). A number of nuclear reactions important to hydrostatic stellar evolution near their Gamow window energy such as ²⁵Mg (p, γ) ²⁶Al, ¹⁹F (p, α) ¹⁶O, ¹³C (α, n) ¹⁶O and ¹²C (α, γ) ¹⁶O will be directly measured. At present, 400 kV high current accelerator and ECR ion source were successfully developed, and the proton and He⁺ (400 keV, 10 mA) and He²⁺ beam (800 keV, 2 mA) were successfully obtained. The development of high-power solid targets and the establishment of experimental data acquisition systems were successfully completed. Ultra-low background fast neutron detectors, 4π BGO detector arrays and large solid angle particle detector arrays were developed and assembled, and the background levels of the ground and CJPL were measured. In general, JUNA project smoothly completed the objectives set in the medium term and passed the assessment of the fund committee (Grade A) and international assessment. (authors)

[en] In this study, research status on radionuclide and colloid migration in underground research facilities including KURT (KAERI Underground Research Tunnel) was investigated. Some foreign underground research facilities constructed in crystalline rock formations such as granite were briefly introduced and compared. International joint researches concerned with the radionuclide and colloid migration were investigated particularly for the Grimsel Test Site (GTS) and Aespoe Hard Rock Laboratory by analyzing major research items, on-going research projects, and future plans.

[en] The SN1987A explosion on the February 23, 1987, gave unique opportunity to see the correlation between the data of different underground installations. It is well known that 4 detectors - at Baksan (BST), Kamioka (K2) and Mont Blanc (LSD) laboratories, as well as the detector of Irvine-Michigan-Brookhaven collaboration (IMB) were running, and these groups have reported on the existence of rare pulse bunches in their data

[en] Studies of diffuse supernova neutrino background (DSNB) by modern underground detectors are reviewed. DSNB neutrino fluxes, their spectra and current experimental limits on their flux are discussed. Currently the best upper limit on DSNB neutrino flux is 2.9 cm"-"2s"-"1. Also posibilities to improve upper limits on future detectors and perspectivies of DSNB neutrino detection are discussed. (paper)
