Do all nuclear plants use water?

All nuclear plants, virtually all coal plants, and some gas-fired plants use steam turbines to generate electricity. Water from a nearby river, lake, reservoir, ocean or estuary is used to cool and condense the turbine exhaust steam at these plants. All nuclear plants use water for cooling; none use dry cooling.

Circulating Water Systems

Nuclear power plants are usually built next to lakes, rivers, and oceans. Not for the scenic views that such locales provide, but because water can absorb the waste heat produced by the plants. Circulating Water Systems at any power plant have two important functions: Filter water before it is pumped to and through the condenser. Cool the

How does a nuclear power plant cooling system work?

These cooling systems requires the consumption of additional water to circulate throughout the plant to condense the steam back into water through heat absorption. Nuclear power plants operate similarly and are typically built near lakes or rivers to facilitate water withdrawals and consumption.

Does a nuclear plant have a cooling system?

Most nuclear plants maintain an independent cooling water source to their safety grade cooling systems (e.g., essential service water) – independent from the circulating water system that cools the condenser. Many of these safety grade cooling systems use once-through cooling, even if the plant has towers for condenser cooling.
