Provides 11% of World’s

electricity

Little to no greenhouse gas

pollution

1 pellet is equivalent to 149

gallons of oil or 1 ton of coal

Nuclear power plants can

run nonstop for months

USING NUCLEAR POWER

BOILING WATER REACTOR

PRESSURIZED WATER REACTOR

Uranium 235 Pellets placed end to end to make Fuel Rods

Fuel Rods placed in Fuel assemblies with control rods

FUEL ASSEMBLY

Fuel Assemblies Placed inside reactor vessel

Control Rods Removed, Fission Takes Place

Fission Reaction Heats up water, which travels through pipes in a closed system

REACTOR VESSEL

Hydraulic like system

Uses spargers, a type of spray nozzle to push water into the reactor

Uses a hydraulic reactor coolant pump to cool down the water

REACTOR VESSEL

A second closed system of water is heated by first

Turns to steam and rotates a turbine

Attached to rotating shaft to turn electromagnet generator

Magnet creates electricity

TURBINE AND GENERATOR

Steam passes through a third closed water system, called condenser coolant

Some plants discharge water into a lake next to the plant

Others Use Cooling towers so water can be recycled.

LAKE OR COOLING TOWERS

ProsA lot of energy

stored in a very small amount of space

Little greenhouse gases

Water can be reused countless times

ConsCreates radioactive

wasteUses 672 gallons of

water per 1 megawatt-hour of energy produced

Second most expensive method for producing electricity

EFFICIENCY

Would produce much more energy than fission reactors

Limitless fuel available

Zero greenhouse gases

Core radioactive for only 100 years
