Sensitivity Analysis of a Steam Generator Model Dynamic Output

model, steam generator. Steam generators Pressurized light water nuclear power plants mainly consist of two separated water loops that exchange heat. The water from the primary loop goes first through the reactor itself where it is heated by the nuclear reaction and then through heat exchangers called Steam Generators (SGs) where it transfers heat to the water of the secondary loop. Secondary water is at much lower pressure (60 bars versus 155 bars for the primary water) so it boils when heated by the primary loop inside the SGs. The steam exiting the SGs by their upper opening flows through the turbines which produce the work eventually converted into electricity by alternators. A SG consists of a cylindrical tank (approximately 20 meters high with a diameter of 3 meters) that contains the secondary steam-liquid mixture. The primary water enter the SG at its bottom and goes through a bundle a U shaped tubes. Thus, primary and secondary waters never mix and the heat exchange unfolds inside the metal the U-shaped tubes and at their internal and external interfaces. The tube bundle is maintained in place by circular plates called Tube Support Plates (TSPs). The TSPs have circular holes to allow for the passage of the tubes and these holes are surrounded b
