From early April 2020, wildfires raged in the highly contaminated areas around Chernobyl nuclear power plant (CNPP), Ukraine. For about 4 weeks, fires spread and into exclusion zone (CEZ) came within a few kilometers of both CNPP radioactive waste storage facilities. Wildfires occurred on several occasions throughout month April. They were extinguished, but weather conditions by airborne embers smoldering led to new starting at different locations CEZ. The forest only completely under...
The results of the study on speciation and mobility uranium in ore processing residues Centralny Yar tailings (CY, former site -Pridneprovsky Chemical Plant Ukraine) are presented.Due to poor neutralization sludge material was dumped into body acidic state.Several incidents with breakage pipeline transporting complex radiochemical solutions caused radioactive spillover onto surface.Two features radiological concern were identifiedsecondary contamination surface amid elevated gamma dose...
Problems Statement and Purpose. The territory of the former Uranium production facility “Prydniprovsky Chemical Plant” (“PChP”) are located in Kamensky city, Dnipropetrovsk region, occupy area upper lower terraces Dnieper River (more than 300 hectares), where remained legacy facilities residues uranium ore processing located. After 1991 concentrates ceased without remediated. Thus, up to 40 million tons radioactive chemical mineral have accumulated within its industrial site at adjacent...
This study provides an analysis of data from long-term (2005-2021) observations the chemical composition groundwater in impact zone former uranium ore processing enterprise (Production Union Prydniprovskyi Chemical Plant (PU “PChP”) city Kamianske, particular, areas near-surface tailings processed residues (“Zapadnoe”, “Central Yar” and others). All on site PU “PChP” were built without installation anti-permeable barriers, therefore under influence atmospheric precipitation, water, formed...
Purpose: Justification the possibility of safe re-use and recycling residues Uranium-containing raw material processing as an element remediation strategy for bringing site former "Prydniprovsky Chemical Plant" (PChP)to a state. Methods: Site specific field studies analytical methods determining radionuclides Uranium-Thorium series, well useful mineral elements in Uranium production, assessment management possible options its recycling. Results: According to results monitoring on...
The article summarizes the results of long-term radioecological monitoring environment radioactive state within former 'Prydniprovsk chemical plant' and adjacent territories at preparatory stage life cycle uranium legacy site. Data analysis have been determined background activity levels natural radionuclides (in particular 238U, 226Ra, 230Th, 210Pb, 210Po) in soils, underground surface waters, air (fall density volume activity), exhalation 222Rn from soil its activity. dynamics trends...
The methodology of radioecological zoning the territory possible radioactive contamination was applied to analyze consequences a hypothetical radiation accident at Khmelnytskyi NPP (KhNPP). With help European decision support system in event RODOS, as well set models aerial and root vegetation, developed Institute for Safety Problems Nuclear Power Plants National Academy Sciences Ukraine (ISP NASU), modeling transport emissions, their deposition on underlying surface agricultural products...
There are many sites in the world, where Environment still under influence of contamination related to Uranium production carried out past. Author’s experience shows that lack site characterization data, incomplete or unreliable environment monitoring studies can significantly limit quality Safety Assessment procedures and Priority actions analyses needed for Remediation Planning. During recent decades analytical laboratories enterprises, currently being responsible establishing specific...
<p>Most of the territory Chernobyl Exclusion Zone (CEZ) is covered by forest. Forest CEZ have accumulated a significant part radioactive release and for many years served as barrier to non spreading radionuclide contamination outside CEZ.</p><p>According classification wildfire danger, forests belong high, above average medium classes, making cases wildfires quite common.</p><p>Poor, sod-podzolic soils Ukrainian Polesye...
<p>Since the 1986 Chornobyl accident transport of radionuclides by Pripyat River shares more than 90% annual total flux radioactivity coming out Exclusion Zone (ChEZ).  90Sr was main contributor to this flux. In course time destruction accidentally dispersed "fuel particles" leads increase mobile, e.g. water-soluble, forms 90Sr  on territories affected by, while fixation 137Cs in soil is reflected significant reduction aquatic outside...
