Considered here is the problem of cooling water-cooled reactors in an emergency, including in emergencies involving a blackout. This problem has become particularly important after the events that occurred at the Japanese nuclear power plant, пїЅFukushima-1.пїЅ Here we present a new emergency reactor-cooling system developed at the Department of Energy Problems at the Saratov Scientific Center, Russian Academy of Sciences. We propose a new way to provide redundant, auxiliary power for nuclear power plants (NPPs) t...

Experience of radiological contamination of land, especially after the Chernobyl and Fukushima disasters has shown the need to explore possible ways of capturing radionuclides in the area affected and adapting the landscape management to this purpose ex-ante the considered accident in terms of prevention. The project "Minimizing the impact of radiation contamination on land in the emergency zone of TemelпїЅn NPP" (2012-2015), dealt with the possibility of utilization of wetlands as retention sites for water carryi...

Knowledge of emitted neutron spectra is crucial to determination of degradation rate of materials or biological shielding designing. Therefore the paper focuses on the neutron spectra measurement using passive activation detectors made from indium and special spectral filters. A neutron radionuclide source made of mixture americium and beryllium was used for irradiation. The irradiation was carried out on the special stand SVICKA that allow generating different spectra in various irradiation channels. The spectral...
