Installing a hydrogen energy complex at nuclear power plants is a well-known approach to solving the problem of providing nuclear power units with a base load under conditions of uneven energy consumption. A method has been proposed to reduce the underburning of hydrogen fuel to almost completely eliminate the entry of unburned hydrogen into the steam power cycle of a nuclear power plant unit. The work has developed a formula and determined the level of reduction in probable damage from explosions and fires at the hydrogen energy complex when implementing measures to reduce underburning. The calculations were carried out using the example of an autonomous hydrogen energy complex previously developed by the authors. The following results were obtained: the reduction in possible damage from explosions and fires is 1.61, 4.03 and 6.46 thousand $ with 20, 50 and 80% damage to the equipment of the hydrogen energy complex, respectively. Taking into account the possible increase in the cost of hydrogen energy complex equipment by 40%, this effect increases to 2.26, 5.65 and 9.04 thousand $, respectively.
