	Beam injectors in tokamaks are utilized for plasma heating and diagnostics. Due to the relatively large distance between the injectors and plasma, the tokamak stray magnetic field inside injectors during the operation should be very low (down to the tenths of Gauss) to avoid the deflection of the ion beams. The Magnetic Field Reduction System (MFRS) should be used to reduce the stray magnetic field produced by the tokamak EM systems and plasma to an acceptable level inside the injectors. In total, the complex MFRS can consist of a passive magnetic shield and active coils to provide the strict design criteria during a plasma scenario. To provide precise computations, detailed numerical models of MFRS should have the dimensions up to several tens of millions of degrees of freedom. Such problem could be solved only with the use of high-efficiency vector algorithms and parallel computations. The paper is dedicated to simulation of MFRS for beam injectors in tokamaks.
