Inspection and disassembly
For many years, the Joint Stock Company Institute Orgenergostroy has successfully examined the construction units of buildings, structures, and power facilities. The following sites demonstrate the company's expertise in this area:
- Determination of technical condition of civil structures of Balakovskaya NPP Power unit №1 Reactor building, including peripheral structures, foundation part, Reactor hall and Containment pre-stressing system;
- Inspection of Volgodonskaya NPP Power unit №2 TG foundation and development of defect repair procedure;
- Inspection of civil structures in order to obtain the materials for development of Preservation design for Voronezhskaya Nuclear Heating plant;
- Inspection of the lower slab of Kalininskaya NPP Power unit №4 TG foundation and assessment of possibility of completion;
- Inspection of civil structures of Khmelnitskaya NPP Power units №№ 3 and 4 (and development of repair documents);
- Inspection of Ryazanskaya SDPP TG foundation;
- Inspection of FTA of “Construction of 410T CCGT unit” object;
- Inspection of buildings and structures for assessment of technical condition of them at Bataan NPP (Philippines).
Within the period 2016-2018 – complete inspection analysis of service life of civil structures of all buildings and structures in process chain of Armenian NPP Power unit №2 (WWER-440). The works were performed in connection with expiry of design operation period and for determination of possibility and the period of further operation. Except for inspection of standard civil structures, the works on assessment of condition of TG foundation and of spent fuel cooling pond lining were performed.
Inspection of civil structures of the main buildings and structures of Kozloduy NPP Power units 5 and 6 (WWER-1000 design) in Republic of Bulgaria was performed in 2014. Inspection was performed for determination of extension of NPP service life for further years due to expiry of design service life.

Inspection and dismantling of civil structures
The technological capabilities of the Joint Stock Company Institute Orgenergostroy enable the development and dismantling of main and auxiliary structures of industrial plant facilities of any complexity for reconstruction, integration, or decommissioning.
Orgenergostroy applies both time-proved and advanced methods of disassembling of reinforced concrete structures, including:
- diamond cutting with chains (ropes) and discs;
- hydraulic cutting using hydraulic monitors;
- splitting into blocks using hydraulic wedges, electrohydropulse method, non-explosive expanding compounds;
- detaching of pieces using hydraulic cutter and hydraulic shear;
- crushing using pneumatic and hydraulic hammers;
- building controlled explosion.
At “Belene” NPP over 150 thous. m3 of reinforced concrete structures and about 20 thous. t of metal structures were disassembled completely. The metal structures were dismantled by disassembling of bolted connections and by cutting applying welding technologies.
