Meaning
A nuclear reactor that uses water as a coolant and moderator; the steam produced can drive a steam turbine.
Classification
Nouns denoting man-made objects.
Examples
- Pressurized water reactor designs typically operate with two separate circuits for coolant and steam generation.
- Most pwr systems include some kind of backup power system for core cooling during shutdown.
- There are also compact PWR designs such as the SMR which aim to make this reactor design even safer.
- France operates many nuclear power stations which house dozens of pwr reactors generating about 75 percent of their power.
- However smaller countries are considering SMRs rather than conventional PWR installations because they offer easier scaling and require lower upfront costs.
