6. Common Misperceptions of Nuclear Energy
Misperception 1:
Nuclear energy is bad for the
environment.
Nuclear Energy: Safe, Clean, and Reliable5
7. Environmental Benefits
• Nuclear energy produces 63.3 percent of all U.S. emission free electricity.
• In 2011, nuclear energy facilities prevented 613.4 million metric tons of carbon dioxide emissions, almost
equal to the amount of carbon dioxide emissions from all U.S. passenger cars.
• Nuclear energy facilities also prevented the emission of 1.41 million short tons of sulfur dioxide and 0.54
million short tons of nitrogen oxide in 2011.
• A nuclear energy facility’s life-cycle carbon emissions are among the lowest of any electricity generation
source at 17 tons of carbon dioxide equivalent per gigawatts-hour, comparable to geothermal (15 tons) and
wind (14 tons).
• Protecting the environment extends to safely managing used fuel, protecting water quality, and preserving and
improving habitat for plants and wildlife.
• All U.S. nuclear energy facilities have extensive environmental monitoring programs, which are under the
oversight of the NRC and state regulators.

13. Response to Events at Fukushima
• U.S. Nuclear Regulatory Commission in 2011
• Initiated special, focused inspections
• Verified no safety concerns requiring immediate action
• Made 12 recommendations for enhancements.
• Institute of Nuclear Power Operations (INPO) in 2011
• Independently required plant assessments
• The preliminary assessments included protection from seismic and
flooding hazards, an extended loss of power to vital safety systems,
and protection of used fuel in storage at U.S. reactors.
• Nuclear industry proposed to
• Place emergency equipment at diverse locations at each reactor site.
• U.S. plants will be supported by off-site equipment pre-staged at
specific locations.
• Acquired or ordered 300 pieces of backup safety equipment at 104
reactors including diesel generators, pumps and emergency and
response vehicles.
• Enhance the ability of nuclear energy facilities to remain safe even if
there is an extended loss of electric power.
• Develop strategies to mitigate external events beyond the design
envelope for nuclear plants.
• Re-analyze potential flooding and loss of ultimate heat sink scenarios.
• Implement improvements to ensure accessible and reliable hardened
vents for Mark I and Mark II boiling water reactor containments. (Of
America’s 104 reactors, 31 have Mark I or Mark II containments.)
• Improve plants’ ability to monitor water level and temperature in
storage pools for used nuclear fuel during an extended loss of electric
power.
• Assess staff needed to respond to a large-scale natural event at
multiple reactors at a site and to implement strategies contained in
the emergency plan.
• Assess communications and equipment used during an emergency to
ensure that power is maintained during a large-scale natural event.
Nuclear Energy: Safe, Clean, and Reliable12
There have been no deaths or cases of
radiation sickness from the nuclear accident,
but over 100,000 people had to be evacuated
from their homes to ensure this.
14. Common Misperceptions of Nuclear Energy
Misperception 5:
Americans get most of their
yearly radiation dose from
nuclear power plants.
Nuclear Energy: Safe, Clean, and Reliable13
15. Radiation Sources
Nuclear Energy: Safe, Clean, and Reliable14
• We are surrounded by naturally occurring radiation.
• Less than 1 / 1000th of the average American’s yearly radiation dose
comes from nuclear power.
• This yearly radiation dose is 100 times less than we get from coal,
[1]
200 times less than a cross-country flight, and about the same as
eating 1 banana per year.

16. Common Misperceptions of Nuclear Energy
Misperception 6:
Nuclear waste cannot be
safely transported.
Nuclear Energy: Safe, Clean, and Reliable15
17. Nuclear Waste Transportation
• Radioactive materials have been shipped in this country for more
than 60 years.
• 3 million packages of radioactive materials are shipped each year in
the U.S.
• As when transporting other commodities, vehicles carrying
radioactive materials have been involved in transportation
accidents. However, NO deaths or serious injuries have resulted
from exposure to the radioactive contents of these shipments.

18. Common Misperceptions of Nuclear Energy
Misperception 7:
There is no solution for huge
amounts of nuclear waste
being generated.
Nuclear Energy: Safe, Clean, and Reliable17
19. Nuclear Waste
• If all the used fuel produced by U.S. nuclear power plants in nearly
50 years were stacked end to end, it would cover a football field to a
depth of less than 10 yards.
[1]
• 96% of this “waste” can be recycled.
[2]
• Used fuel is currently being safely stored.
• The U.S. National Academy of Sciences and the equivalent scientific
advisory panels in every major country support geological disposal
of such wastes as the preferred safe method for their ultimate
disposal.

22. Common Misperceptions of Nuclear Energy
Misperception 9:
Nuclear energy can’t reduce
our dependence on foreign
oil.
Nuclear Energy: Safe, Clean, and Reliable21
23. Nuclear Energy and Dependence on Foreign Oil
Near-term
• nuclear power can provide electricity for expanded mass-transit and
plug-in hybrid cars.
• Small modular reactors can provide power to islands (e.g. HI, PR,
Nantucket and Guam) currently burning oil to generate electricity.[1]
Longer-term
• Nuclear power can reduce dependence on foreign oil by producing
hydrogen for fuel cells and synthetic liquid fuels.

25. Reliable Electricity
• Nuclear energy is a reliable energy source, providing on-demand baseload electricity
24/7. The average nuclear energy facility is on line 90 percent of the time,
generating on-demand electricity around the clock .[1]
• Nuclear energy facilities have the highest average capacity factor among all U.S.
electricity sources. A facility’s “capacity factor” compares its actual energy
production with how much it could produce at full operating power during the year.
This is a crucial measure of reliability and a plant’s online performance, and it varies
substantially by energy source. [1]

• Production costs at nuclear energy facilities in 2011
averaged 2.19 cents per kilowatt-hour, cheaper than coal
(3.23 cents) and natural gas-fueled plants (4.51 cents).
• The average nuclear energy facility pays approximately
$16 million in state and local taxes and $67 million in
federal taxes annually.
• Each nuclear energy facility generates about $470
million annually in sales of goods and services in the
local community.
• Approximately $40 million is spent annually in wages at
each facility.
• Ten license applications are being reviewed by the
Nuclear Regulatory Commission for 16 new reactors.
• Five new nuclear reactors are under construction in three
states: Georgia (Vogtle 3 and 4), South Carolina (V.C.
Summer 2 and 3) and Tennessee (Watts Bar 2).
• Some 19 companies and consortia are studying,
licensing or building more than 30 nuclear power
reactors.
Nuclear Energy: Safe, Clean, and Reliable26
•Up to 21,000 high-paying jobs will be created if
all planned nuclear reactors come on line.
•One reactor creates up to 3,500 jobs at peak
construction.
•A new nuclear energy facility creates 500
permanent jobs per 1,000 megawatts of
electricity generating capacity, compared to 190
jobs for a coal plant, 50 for a wind farm and 50
for a natural gas plant.
