Two new water cooled air compressor systems with a producing capacity of 25 m³/min each have been put into commercial operations at KhNPP in order to ensure compressed air continuous supply for technological and repair needs. The manufacturer of the systems is a Turkish company DALGAKIRAN MAKINA SAN.

The former compressors replacement process was started back in 2007. The required package of documents, including a project developed by JSC Kyiv Research and Design Institute «Energoprojekt», was prepared for implementation of compressor equipment renewal program.  Increasing need for compressed air was the basic argument for renovation of the fleet of compressors.

Compressor systems reconstruction was started with domestic compressors manufactured by Sumy JSC «RPJSC «SRI Compressormash”. The first more powerful BB-25/8 A type system was commissioned in early 2018. It became a test case because air-cooling of compressed air was a «novelty” for chemistry department: precursor compressors operated on water-cooling for over 30 years.

New compressors installation and commissioning was carried out by personnel of energy-repair department and electric shop of KhNPP without involving contractors. Chemistry department staff performed pre-commissioning activities.

Dmytro Korsun, Deputy Head of chemistry department for reconstruction and modernization, explains that this state-of-the-art equipment will help the Khmelnytskyy Nuclear Power Plant maintain the key technological processes at the appropriate level, increase reliability and raise compressed air production from 96 m³/min (capacity of four former compressors) to 155 m³/min.

Currently there are five new compressors at the plant compressor station (PCS). Owing to them, it is possible to provide a sufficient amount of compressed air, which will be needed both to establish full operation of the radioactive waste treatment facility being built at KhNPP site, and to finalize the construction of power units 3 and 4.
