Main contractors and suppliers:

General contractor — Northern Construction Administration;

General reactor hardware supplier — Production Association «Izhora Plant»;

General turbine designer — Production Association “Leningrad Metallic Plant”;

Designer of main building and reactor part — Moscow branch of the “Atomenergoproject” Institute;

Developer and manufacturer of electromechanical equipment (Control, Monitoring & Protection; FC Integrity Monitoring; and Fuel Cladding Failure Detection (FCFD) systems) — Production Association “Obukhovo Plant”;

Development of technical documentation and manufacture of the NPP Automated Process Control System hardware — Leningrad Scientific & Production Association “Krasnaya Zarja”.

An agreement was obtained from Westinghouse Corporation to develop and manufacture, jointly with NIKIET, the Automated Process Control System for an NPP with the MKER-800 reactor in the framework of a joint Soviet-American project.

The calculated and experimental justification for the most crucial assemblies and systems was performed on a competitive basis. The comparative analysis of the results as well as their correlation with foreign experience were carried out.

Nuclear Power Plant with the MKER-1000 Reactor

The MKER-1000 project incorporates a diversity of advantages typical of the channel-type reactors, e.g.:

  • the possibility of on-load refuelling and, through this, an enhanced fuel burnup and a small operational reactivity margin;

  • a multi-loop main coolant circulation circuit mitigating the size and consequences of accidents due to equipment and pipe rupture;

  • a continuous integrity monitoring of the fuel channels and fuel assemblies allowing for their prompt replacement and, consequently, a timely restoration of safety barriers;

  • a flexible fuel cycle allowing for a comparatively easy adaptation of the reactor to the domestic fuel balance conditions.
