Prydniprovsky Chemical Plant Radioactive Dumps
The now-defunct Prydniprovsky Chemical Plant (; ''Prydniprovsky khimichnyi zavod'', ''PHZ'', also PChP) in the city of Kamianske, Ukraine, processed uranium ore for the Soviet nuclear program from 1948 through 1991, preparing yellowcake. Its processing wastes are now stored in nine open-air dumping grounds containing about 36 million tonnes of sand-like low-radioactive residue, occupying an area of 2.5 million square meters. The sites, improperly constructed from the very beginning, have been abandoned by the industry long ago and remain in very poor condition. The top concern is the dumps’ proximity to both the large Dnieper River and city residential areas. According to government experts, the dams separating the grounds from soil water are already leaking, causing the pollution of Dnieper basin. It is believed that further deterioration of the dams, irrespective of any outer accidents, may cause a devastating radioactive mudslide. The Ukrainian government is now tightening ...

Kamianske
Kamianske (, ; ), previously known as Dniprodzerzhynsk from 1936 to 2016, is an industrial city in Dnipropetrovsk Oblast, Ukraine, and a port on the Dnieper, Dnieper River. It serves as the administrative center of Kamianske Raion and Kamianske urban hromada. Population: On 19 May 2016, it was renamed back to its historical name of Kamianske. Along with the city's name change, the city's hydroelectric station was renamed to Middle Dnieper Hydroelectric Station, Middle Dnieper Hydroelectric Power Plant. Besides the hydroelectric station, the city houses a few other industrial enterprises: Prydniprovsky Chemical Plant radioactive dumps, Prydniprovsky Chemical Plant (closed in 1991), Bahley Coke Factory and Dnieper Metallurgical Combine. History The first written evidence of settlement in the territory of Kamianske appeared in 1750. At that time the villages of Romankove and Kamianske, which make up the modern city, formed a part of the Zaporozhian Sich. The city was known as ...

Threat Of The Dnieper Reservoirs
The Dnieper reservoir cascade or Dnieper cascade of hydroelectric power stations (HPP) () is a series of dams, reservoirs and hydroelectric power stations on the Dnieper river in Ukraine. It was created to prevent uncontrolled flooding and improve water transportation infrastructure. Coordination and operation of all dams on the Dnieper is conducted by government company Ukrhydroenergo. In 1970, the Kyiv dam partially prevented flooding in comparison with the 1931 Kyiv flooding. As with any dam, the water reservoirs of the Dnieper in Ukraine pose a significant threat of a large-scale, human-made disaster if their dams fail. Those concerns were raised in particular in connection with the 2009 Sayano–Shushenskaya Dam disaster. Concerns had yet again been raised regarding an air attack of the Kakhovka Dam on July 11, 2022. The Kakhovka Dam would later fail in the result of an explosion that occurred on June 6, 2023. Flooding will impact downstream communities such as Kherson an ...

Chemical Companies Of Ukraine
A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. If a mixture is separated to isolate one chemical substance to a desired degree, the resulting substance is said to be chemically pure. Chemical substances can exist in several different physical states or phases (e.g. solids, liquids, gases, or plasma) without changing their chemical composition. Substances transition between these phases of matter in response to changes in temperature or pressure. Some chemical substances can be combined or converted into new substances by means of chemical reactions. Chemicals that do not possess this ability are said to be inert. Pure water is an example of a chemical substance, with a constant composition of two hydrogen atoms bonded to a sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dnieper Basin
The Dnieper Basin is the drainage basin of the Dnieper River, covering an area of . Its water resources compose around 80% of the total for all Ukraine. Geography The Dnieper Basin lies within Ukraine, Belarus, and Russia. It borders on the Volga Basin in the northeast, on the Donets River Basin in the east, which belongs to the Don River Basin, and in the southeast on several small watersheds, the watercourses of which flow in flow into the Sea of Azov. The southern edge of the watershed borders on other small watersheds whose rivers flow into the Black Sea. In the south of the catchment area, the main river Dnieper runs into a peak west of the city of Kherson and runs across the Dnieper–Bug estuary, where the stream flows into the Black Sea. In the southwest, the catchment area of the Dnieper borders on the Southern Bug Basin, which attaches laterally to the catchment area of the Dnieper. To the west is a small border with the Dniester Basin, as well as the Vistula Basin. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Engineering

Radioactive Waste
Radioactive waste is a type of hazardous waste that contains radioactive material. It is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into 3 categories: low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity; intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding; and high-level waste (HLW), which is highly radioactive and hot due to decay heat, thus requiring cooling and shielding. Spent nuclear fuel can be processed in nuclear reprocessing plants. One third of the total amount have already been reprocessed. With nuclear reprocessing 96% of the spent fue ...
