“…This circuit is obviously simplified compared to reality, but it addresses enough complex connections between each component to simulate a consistent physical behavior to study baseload and load following modes of production. Similar schematic Rankine loop has already been used to carry out interesting results such as the optimization of mass flow regulation at turbine extraction stages [2] or the improvement of water reheater's efficiency and the turbines behavior for off-design load conditions [3][4].…”

The penetration of intermittent low-carbon energies in the French electric mix challenges the need of enhancing the manageability of the French nuclear fleet. Most of the French nuclear reactors have been devised to do load-follow operations in order to ensure the supply and demand balance anytime. However, it has been shown that the less the share of electricity production from nuclear energy (which would be mainly compensated by the development of wind and solar energy), the more load-follow transients will be planned to manage summertime peak of electric over-production or conversely winter season peak of underproduction. A coupling between the secondary loop and the cooling circuit of a pressurized water reactor has been implemented in addition to a simulator oriented French 1300 MW reactor model. We present here our modeling of the steam turbines, the moisture separator, the water reheater and the condenser for a typical P'4 French nuclear reactor provided with an open-loop cooling circuit. As we study off-design load conditions, we simulate a load transient based on real electricity production profile done in the past few years. We compare the temperature of the water withdrawn from the cold source downstream of the plant measured on site and the one we calculate from our model.

“…The steam power plant working is based on Rankine cycle, where the increasing of the superheated steam temperature lead to improving the thermal efficiency of cycle as thermodynamics process [14][15][16]. Later, researchers tried to improve the efficiency of the plant by increasing steam pressure, which resulted in degradation of the steam quality at the turbine exhaust [17].…”

In this work, the evaluated performance of thermal station is mechanically studied by determining the performance parameters for generative unit, which it is given the calculation model by doing heat balance for each one of its principal parts. A comparison is done between the particle results, which are obtained from the station and the theoretical results which its calculated from the basic first law thermodynamics, The different working loads (40%, 70%, 100%) of its completes load have been considered in order to determine the optimum working circumstances, in addition to demonstrate the effect of some working and environmental circumstances on unit performance.
