Abstract
The article aims to assess the efficiency of hydrogen facility based on the night-time off-peak energy produced by the nuclear power plant (NPP) in comparison with the pumped storage power plant (PSPP) under conditions of fatigue wear of the master equipment. The relevance of hydrogen facility coupled to NPP units is evaluated. Evidenced is provided for the necessity of assessment and accounting of fatigue wear of the master equipment in the hydrogen facility. A new methodology for assessing the working resource of the master equipment has been worked out with account for the turbine rotor using of a condensation type turbine C-1000-60 / 1500 example under fatigue wear conditions. This methodology is used to determine the maximum number of cycles prior to fracture in the critical elements of the master equipment depending on the cyclic loads per day. A nomograph has been designed to estimate the prime cost of on-peak energy of the hydrogen system considering fatigue wear of the basic facility. Competitive advantages of the hydrogen complex and the PSPP is estimated based on the net present value criterion (NPV). It is shown that the hydrogen system can compete with the PSPP under its relative capital investments at about $ 660 / kW. The PSPP versions under the relative capital investments over $ 660 / kW lose their competitiveness compared to hydrogen complex.
