Department of The Chief Designer of Pressure-Tube Power Reactors

Yu.M. Cherkashov
Chief Designer of Pressure-Tube Power Reactors

Main Activities

Upgrading of operating RBMK reactors:
- improvement of the operating logic of safety systems
- computational validation of upgrading projects
Safety analysis for operating plants (in-depth safety assessment of operating NPPs)
Enhancement of the operational safety of RBMK plants:
- preparation and improvement of operational documentation
- development of symptom-based emergency procedures
Engineering support in operation of RBMK plants
Supervision of equipment manufacture for operating plants
Development of advanced pressure-tube reactors
Service life management and decommissioning of pressure-tube reactors
Technical assisstance to plant Operator in case of emergency at an RBMK plant (Engineering Support Centre for RBMK NPPs)


Leningrad NPP with RBMK-1000 reactors


Main Control Room of Ignalina 1 (RBMK-1500)	Refuelling system in the reactor hall, Kursk 1

MKER-1000

The MKER-1000 reactor is a next step in development of pressure-tube reactor facilities in Russia. The performance and safety level of this reactor meet the current requirements for NPPs planned to be built early in the 21st century. The MKER-1000 development relies on 50-year experience in design and operation of domestic pressure-tube reactors with the total service record of about 500 reactor-years.

Design distinctions:

passive safety features depending for their operation on natural laws of physics;
reinforced concrete containment;
on-load refuelling which ensures consumers against interruptions in energy and heat supply;
equipment for production of a broad spectrum of isotopes employed in medicine, research and industry, and irradiation facilities for modification of material properties.
