Results of investigations of issues of reiiable and economically viable municipal district heating based on small pool-tipe reactor RUTA (heating reactor with atmocperic primary coolant pressure) are presented.
Conceptual design of RUTA are available for 10 to 70 MW reactor thermal capasity. Desctiption of basic design features of reactors are presented in the paper as well as their neutronic and technical characteristics. Prospects and benefits of applicotion of RUTA reactors in district heat supply sistems and possibility of broaden of area of their usefull utilization:
• as an energy source for nuclear desalination,
• as a neutron source for:
- medical and industrial radioisotop production,
- medical neutron therapy beams,
- irradiation of polymeric films.
Nessesary first step for implementation of any new nuclear technology is to be construction and operation of a first-of-a-kind unit. Erection of this unit for RUTA reactor is sujested to implement at IPPE-site in Obninsk where it could be done in shorter term and with minimal constructiom expenditures.
In 2004 several organizations of ROSATOM (AEP, ENTEK and IPPE) were developed "Feasibility study of demonstration project of District Heating Plant RUTA 70 MWth at the IPPE-site". Key results of the Feasubility Study related to the project design and economics are presented in the paper.
