Abstract
The article considers the layout solutions of the electrolysis shop of the hydrogen superstructure outside the territory of the nuclear power plant. To do this, an annual risk assessment was carried out taking into account the reliability and explosion risk for 1-4, 8 and 16 separate electrolysis shops installed on the site of the hydrogen superstructure. When taking into account equipment breakdowns, with possible explosions and fires in electrolysis plants, the risk due to fires and explosions was several times lower than the risk associated with equipment failures. Calculations showed that the transfer of electrolysis plants to increased hydrogen productivity in the event of failure of one of the cells is the best option in comparison with the reduction in the generation of electricity at the steam turbine installation of the hydrogen superstructure.

Summary
Для оценки возможных ущербов оборудованию в электролизном цехе и дополнительных расходов денежных средств необходимо оценить расход получаемого водорода, определяющего мощность паротурбинной установки (ПТУ) водородной надстройки, и суточную производительность её работы. Мощность электролизного цеха составила 197 МВт, при удельном расходе электроэнергии на электролиз 4 кВт·ч/нм3 и плотности водорода 0,09 кг/нм3. Связанного с утечкой водорода в одном из электролизеров и дальнейшего обрушения кровли, все это приведет к выходу из строя других электролизеров.
