Branch “SS “Atomremontservice”

In order to improve the quality management and efficiency of repair activities carried out at Ukrainian nuclear power plants, on November 24, 2000, State Enterprise “NNEGC “Energoatom” signed Order No. 821 on the establishment of Separate Subdivision “Atomremontservice” on the basis of Centralized Maintenance Center of State Specialized Enterprise ChNPP.

On February 21, 2001, Separate Subdivision “Atomremontservice” was included in the Unified State Register of Enterprises and Organizations of Ukraine (certificate of the State Statistics Committee of Ukraine No. 1494-01).

The branch “Separate Subdivision “Atomremontservice” (branch “SS ARS”) has its own production sites at Ukrainian nuclear power plants: branch “SS KhNPP”, branch “SS SUNPP”, branch “SS RNPP”.

Safe and efficient performance of complex and non-routing maintenance activities, including design, installation, repair, reconstruction and modernization of equipment at Ukrainian NPPs, safe operation of the Centralized Spent Nuclear Fuel Storage Facility, as well as personnel certification for non-destructive testing in accordance with the requirements of DSTU EN ISO 9712.

Branch “SS “Atomremontservis” has 40 permitting documents to carry out its activities. Branch “SS ARS” has confirmed the functioning of the quality management system, occupational health and safety management system, and environmental management system in accordance with the requirements of international standards DSTU ISO 9001:2015 (ISO 9001:2015, IDT), DSTU ISO 45001:2019 (ISO 45001:2018, IDT), DSTU ISO 14001:2015 (ISO 14001:2015, IDT).

The personnel of the branch “SS “Atomremontservis” are highly qualified employees with many years of practical experience in nuclear industry, equipped with advanced technologies, unique equipment and facilities, that allows the staff to effectively perform work of any complexity at all NPPs of Ukraine.

Branch “SS “Atomremontservice” includes the following departments:
