Optimization of Sizing and Operation of a Nuclear District Heating System Using Teplator, Gas Boiler and Heat Storage

Popis výsledku v původním jazyce

Expansion of the nuclear energy-based district heating systems can effectively contribute to the elimination of CO2 emissions, reduce the dependency on fossil fuels, supply the heating demand with higher efficiency, and are eligible to be competitive compared with the individual heating systems. Consequently, the interest in using heat-only small modular reactors for district heating applications is growing, and some concepts such as Teplator are recently proposed. A flexible operation and fast load following are required, while generally, nuclear power plants are designed to be operated at nominal capacity, and boosting flexibility at nuclear plants is technically complicated. Therefore, heat storage or auxiliary boilers could be adequate for load following and peak shaving, reducing the total costs by decreasing the required capacities of the nuclear plant and heat transmission system. In this study, the optimization of the design and operation of a nuclear district heating system using heat storage and auxiliary boilers is formulated. The capacities and hourly-based operation of the heat generation units and the charging and discharging schedule of the thermal storage are optimized. The technical constraints, such as maximum charging/discharging power rates of the heat storage, or the power ramp rate of the heat generation units, are included in the model.
