The aim of this study is to investigate the hydrogen production rate of a hybrid cycle magnesium chloride (Mg-Cl) cycle hydrogen production facility integrated into the Peaceful Nuclear Explosive Reactor (PACER). 1000 MW of power is generated by explosions of 2 kt intensity at the center of the nuclear fusion reactor every 40 minutes. Hydrogen production and neutronic calculations of the PACER fusion-driven thorium-based molten salt reactor have been performed. Time-dependent calculations were made using 20 mol% ThF4 and 80 mol% LiF by volume. The energy multiplication factor (M) was obtained by neutronic calculations. During the approximately 20 years of operation of the PACER fusion reactor, the energy multiplication factor (M) value was calculated to be approximately 1.33 at the beginning and approximately 13.28 at the end of the operation period. The heat energy generated from the reactor is transferred to steam through the intermediate heat exchanger. This energy is then divided into two and a portion of it goes to the gas turbine to produce electricity. The other part goes to the hydrogen production facility to meet the heat energy required by the Mg-Cl cycle. The electrical energy required for the cycle is 295.50 MW and the heat energy is 196.82 MW. Under these conditions, the hydrogen production ratio ( ) of the hybrid magnesium chloride (Mg-Cl) 455cycle hydrogen production unit integrated into the reactor was calculated as approximately 14.32 kg/s at the beginning and approximately 208.90 kg/s at the end of the operation period.
