The design and operation of vertical steel tanks (VS) in Ukraine are subject to strict regulations. This is necessary to ensure the safety, durability and reliability of tanks, especially when storing hazardous liquids such as oil, chemicals and fuel. In this article, we will consider the main standards that need to be taken into account when designing and operating a nuclear power plant in Ukraine.
Basic regulations and standards
Before designing and operating vertical steel tanks (VS) in Ukraine, it is necessary to take into account key standards that ensure safety and durability. Here are the main ones:
DSTU B EN 14015:2010
It is one of the key standards governing the design, installation and testing of liquid storage tanks. It describes the requirements for materials, welding and tightness tests. It is important that all these stages are strictly followed, as the safety of operation depends on it.
DSTU 2651:2010
This standard establishes requirements for steel materials used in the manufacture of tanks. For example, 09G2S steel, which combines strength and corrosion resistance, is often used for the construction of RVS. Strict adherence to this standard guarantees the durability of the structure.
SNiP 2.09.03-85
A document describing the general requirements for the design of steel structures. It prescribes the rules for calculating the load on the structure, welding features and quality control of materials. This is an important standard that helps take into account all possible loads so that the tank does not deform or collapse during operation.

Peculiarities of designing in Ukraine
- Consideration of seismic activity:
There are regions with increased seismic activity in Ukraine. Therefore, possible earthquakes must be taken into account when designing reservoirs. In such areas, tanks are designed with additional reinforcements to make the structure resistant to soil fluctuations. - Hydraulic
After completion of construction, the tank must undergo mandatory hydraulic tests. This means that the tank is filled with water to check its tightness and the reliability of the welds. Such a test helps to detect possible defects before the start of operation. - Anti-corrosion
An important part of tank design and operation is anti-corrosion protection. Steel can be exposed to corrosion under the influence of the external environment, especially if the tank is in aggressive conditions (salt water, chemical reagents). Therefore, various methods of protection are used - from the application of special coatings to the use of cathodic protection.
Operation of RVS
- Regular checks and maintenance:
In order for the tank to last as long as possible, it is necessary to carry out regular inspections and maintenance. The welds, the condition of the anti-corrosion coating and the general tightness of the tank are checked. This allows timely detection and elimination of possible problems. - Quality control
Since welding is a key element of the construction of the RVS, its quality is checked not only during installation, but also during operation. For this, ultrasound tests, visual examinations and other diagnostic methods are used. - Environmental
In Ukraine, there are strict regulations regarding environmental protection. It is important for enterprises using RVS to minimize the risks of leaks and environmental pollution. This is achieved by installing special vapor capture equipment and conducting regular environmental inspections.
Conclusion
Adherence to standards and regulations in Ukraine is not only a requirement of the law, but also a guarantee of safety and durability of vertical steel tanks. Proper design, quality materials and regular maintenance allow you to use the tanks for decades, ensuring the safe storage of liquids.
