Nuclear waste is understood any substances and objects that have a high radiation background were previously used in the production process and at the moment do not represent any value. This is a special category of “garbage”, which requires an extremely responsible and professional approach.
How nuclear waste is formed?
“Phoning” garbage appears as a result of the activities of the relevant industrial enterprises, nuclear power plants and even medical institutions. The process of its formation is completely different, but three main groups can be distinguished.
The contents of ventilation. This is the socalled gaseous form of waste, which appears as a result of the operation of industrial installations. Many technological processes provide forced ventilation, through the pipes of which the smallest particles of radioactive substances are drawn. Of course, such a ventilation system must have a very reliable collection and treatment facilities.
Liquids. Liquid nuclear waste appears in specific production. For example, this includes solutions from scintillation meters (devices for registering nuclear particles), research devices and other similar technology. In this group and what remains after the processing of nuclear fuel.
Solid waste. Hard radioactive garbage is parts of research and diagnostic apparatuses, various techniques, as well as consumables for them. This can be waste of various laboratories, pharmaceutical enterprises, hospitals, as well as glazed radioactive substances obtained in the process of processing radioactive fuel.
How radioactive substances dispose?
The recycling process directly depends on the strength of the radiation background. There is a “phony” garbage that does not pose a very great danger, but you can’t just throw it away. More often these are waste from hospitals and laboratories in the form of films from xrays and other similar “consumables”. These are medical waste “D”, which pays special attention.
The radioactivity of such waste is small and the process of decay of substances that create a background passes quite quickly. Therefore, such garbage is placed in metal containers tightly sealed with cement. These containers are then stored at time venues, and after a decrease in the radiation background to normal limits, the contents are disposed of at ordinary garbage training grounds.
Another thing is when it comes to the waste of industrial enterprises. In this case, radioactivity is much higher and volumes larger. Almost always “phoning” substances are laid for storage, but not on temporary sites, but in specialized storages, because they will have to store them for several centuries.
What is a nuclear burial ground?
Nuclear burial grounds are called structures designed for long and safe storage of radioactive waste. They are complex engineering solutions that obey state standards.
Such storage facilities are in many corners of the world, and in them countries with nuclear energy are stored radioactive garbage. The solution is quite controversial, because in the case of depressurization of containers, a very largescale disaster can occur. Especially when you consider that a certain number of nuclear waste containers several decades ago were flooded in the Atlantic Ocean. But completely dispose of, that is, to neutralize or destroy, mankind has not yet learned how to waste from the “background”.
