The energy, which requires for solving modern energy-intensive tasks of spacecraft control, can be given only by nuclear power plants. The spectral method is suitable for simulating automatic control systems of a nuclear power plant. Presently various mathematical computer-oriented systems and their extension packages are used to simulate control systems by the spectral method. In this paper the spectral method is applied for simulating automatic control systems of a nuclear power plant on conditions that it is described by the point kinetics equation. In order to simulate such control system the MLSY_SM extension package for Mathcad is used.
