The possibility of power module development as the first step for the development of an orbital power state (OPS) is reviewed in this report. The most probable OPS scheme is a laser system with direct nuclear pumping. Since this task is not yet been defined well enough in its technical form, a better developed prototype has been selected in the form of a free electron laser with the power system on the basis of a gas core nuclear reactor (MGD)—generator and multi‐modular closed gas turbine system. Taking into consideration that many of the elements of this orbital complex are in the stage of advanced development within current programs in different countries, we propose to continue the research and development of the remainder of the key elements.This work was carried out earlier for military purposes but was halted after the end of the cold war. It is proposed to perform this work within the framework of international cooperation, and a lot of the achievements of the Russian nuclear and aerospace technology will be utilized in the project. It will be a worthwhile task to achieve within 6−8 years the development of an orbital power module with a shortwave laser having the power of NL=100 kW for short−time periodical energy transmision from the 500 km orbital to a stationary site in Eastern Siberia. The power supply for this laser is based upon a closed high temperature gas turbine system with a graphite heat accumulator, which is charged with electricity generated by the ‘‘Topaz’’‐type nuclear power system. ©American Institute of Physics 1995
