3. 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.
4. NUCLEAR
Advantages:
Relatively cheap to
operate
require relatively little
fuel
No pollution
Disadvantages:
Expensive to build
Waste
Security

6. We keep our fuel (solid uranium pellets) sealed in
zirconium rods.
7. 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.
9. 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.

13. 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
14. 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
15. 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
