Building a nuclear power plant, Manoir Industries expertise defined the stainless steel primary loops

Pressurized water reactors are today the most common functioning nuclear powerplants. They are designed with three successive coolant loops. The primary loop drives the heat extracted from the nuclear reaction towards steam generators. The steam generated within secondary loop then drives steam turbines that generate electricity. The coolant water within primary loop circulates within the reactor. It is highly pressurized at around 150 bar to remain liquid at high temperatures (350°C). The primary loop is a critical component that…
