TPP-3 - Transportable nuclear power carried on the four self-propelled tracked chassis, established on the basis of the T-10. TPP-3 was developed in the Physics and Power Engineering in Obninsk. The chassis has been developed in OKB Kirov Plant by lengthening the chassis of the T-10 (and, consequently, increasing the number of rollers to 10) and increasing the width of the track to keep ground pressure to the extent necessary.
Two-circuit thermal capacity of the heterogeneous water-moderated reactor that is installed on the two self-propelled - 8,8 MW (electricity, with generators - 1,5 MW). On the other two mobile units located turbine, generator and other equipment.
TPP-3 entered into trial operation in 1961. Subsequently, the program was phased out.
