In the article presents the problem of modeling the reliability for the thermal control system of «Progress » cargo transportation spacecraft. Model is founded on the basis reliability block diagram, phase block diagram, fault tree methodology, implemented in the software package Relex. The simulation results are proposed to use for the program evaluation as a priori failure level reliability of the thermal control system «Progress» cargo transportation spacecraft during electrical testing.
