Abstract

The paper presents new generation reactor - modular helium reactor with gas turbine (GT-MHR), which satisfies the requirements of the developing nuclear power.

The paper describes the reactor plant and peculiarities of GT-MHR technical concept, such as high efficiency (about 48%) of electric power generation, increased safety of the plant, etc. The technologies, which are the innovative essence of GT-MHR project, are:

  1. fuel in the form of fuel particles with multi-layer ceramic coatings which confine fission products at high temperatures (of about 1600°);
  2. large gas turbines;
  3. single-shaft vertical turbomachine design;
  4. electromagnetic bearings;
  5. high-effective compact heat exchangers.
Main technical and economical indices of GT-MHR project are presented.
