A pound is a pound. Or is it?THE COMBUSTION OF ONE POUND OF COAL PRODUCES ONE KILOWATT HOUR OF ELECTRICAL ENERGY.

IN COMPARISON, THE FISSION OF ONE POUND OF URANIUM 235 PRODUCES 3 MILLION KILOWATT HOURS OF ELECTRICAL ENERGY.

NUCLEAR Advantages:

Relatively cheap to operate

require relatively little fuel

No pollution

Disadvantages: Expensive to build Waste Security

We keep our fuel (solid uranium pellets) sealed in zirconium rods.

Fuel Cells

• 7 Trucks, each carrying 6 cases of 2-12 foot high fuel cells, can fuel 1000MW reactor for 1.5 years. (84 fuel cells)

• To operate a coal plant of the same output and same timeframe would require 1 train of 89-100 ton coal cars EVERY DAY! This would produce 350,000 tons of ash and 4 million tons of CO & CO2.

NUCLEAR REACTIONS

A SUBSTANCE USED TO SLOW NEUTRONS FROM THE

HIGH SPEEDS AT WHICH THEY ARE RELEASED IN FISSION

TO LOWER, MORE EFFICIENT SPEEDS WHICH INCREASE

THE PROBABILITY OF CAUSING FISSION.

How it works

Fun Radiation Facts!

• The average person is exposed to 300 mrem/yr from natural sources and accepted risks (medical exams, flying)

• Working in US nuclear power plants will typically yield an exposure of <100 mrem/yr (significantly less in US Navy reactors)

• For comparison, a radiologist receives approximately 500 mrem/yr

Fun Radiation Facts!

• A person would get 1 mrem of exposure from:– Three days of living in Atlanta– Two days of living in Denver

• The loss of life expectancy from 1 mrem is about 1.2 minutes. Compare that to:– One cigarette reduces life expectancy by 7

minutes

Consequences of Radiation Exposure (if entire dose is received at once)

• These are in REM! (1000 millirem)

REM Effect– 0-25 No observable effect – 25-100 Slight blood changes – 100-200 Significant temporary reduction in

blood platelets and white blood cells– 200-500 Severe blood damage, nausea, hair

loss, hemorrhage, death in many cases – >600 Death in less than two months for over

80% of people
