Deterministic modeling method of tornado impact at chernobyl NPP coolant pond

Вісник Національного технічного університету «ХПІ». Серія: Механіко-технологічні системи та комплекси, 2017
В роботе, на основе использования модельных подходов, предложенных В. И. Скалозубовым, выполнено исследование для оценки параметров волны цунами, вызванной влиянием смерча на водную поверхность ВО ЧАЭС. При определенных условиях волна может иметь  высоту превышающую высоту отгораживающей дамбы и в таком случае  и вызвать переливание радиоактивных ...

Radon and Its Effect on the Radiation Situation in the Chernobyl NPP Sarcophagus

Atomic Energy, 2018
During studies performed in 2010–2014, in the under-reactor rooms and deaerator stack of the sarcophagus at the Chernoby NPP, the average volume activity of radon was ~100 Bq/m3 and the average coefficient of equilibrium of radon and its daughter products was ~0.7. The maximum volume activity of radon reached 666 Bq/m3. The daughter products complicate

Surface activity and dose rate distribution inside 4th reactor hall of Chernobyl NPP

IEEE Transactions on Nuclear Science, 1998
A gamma locator designed to conduct contamination surveys inside the reactor hall of the Chernobyl NNP 4th unit is developed. The device consists of detector head and remote control computer connected with a cable (>150 m). The detector head is a collimated scintillator-based gamma-ray detector.

Radiation monitoring in Bryansk Polesie twenty-one years after the Chernobyl NPP accident

Russian Meteorology and Hydrology, 2009
Bryansk Polesie is the most 137Cs-contaminated region of the Russian Federation after the Chernobyl NPP accident, where in 2007 (i.e., 21 years after the accident), the radiation monitoring was conducted within the Russia-Belarus Union State Program. The paper is based on the comparison of data obtained in the settlements and at the nearby landscape ...

Factors governing strontium-90 export with surface runoff in the Chernobyl NPP restricted zone

Water Resources, 2016
Statistical analysis of collected data revealed priority factors affecting radionuclide migration in water. Considerable changes in the coefficients of correlations between the many-year values of those factors and the water export of 90Sr make it possible to identify the stages associated with a mass passage of primary 90Sr inputs into water-soluble ...

Observation of radioactive aerosols in chernobyl after the accident at the fukushima-1 npp

Atomic Energy, 2012
The results of a determination of the concentration and dispersity of radioactive aerosols in the local zone of the Cover in spring 2011 are presented. Aside from aerosols ‐ products of the accident at the Chernobyl NPP in 1986, technogenic 131,132 I, 132 Te, and 134,136 Cs contained in the emissions from the damaged units of the Fukushima-1 NPP and ...

Bubbler Basin and Steam-Distribution Corridor of the Chernobyl NPP Block 4: New Data

Radiochemistry, 2003
Information on the lava-like fuel-containing materials (LFCMs) accumulated in the bubbler basin and steam-distribution corridor of the Chernobyl NPP Block 4 is critically summarized and verified. The amount of the fuel in these rooms is estimated, and the verified results of γ-spectrometric, radiochemical, and elemental analyses of the LFCMs are ...
