More than 65% of the commercial reactors in the United States are pressurized-water reactors or PWRs. These reactors pump water into the reactor core under high pressure to prevent the water from boiling. The water in the core is heated by nuclear fission and then pumped into tubes inside a heat exchanger.
Another advantage of graphite is that it can endure huge numbers of charging and discharging cycles and is easy to manufacture [64], [65].
