3. Nuclear Power Plant
A nuclear power plant is a thermal power
station in which the heat source is a
nuclear reactor.
Nuclear power plants are usually
considered to be base load stations.
4. History
September 3, 1948 the X-10 Graphite Reactor in
Oak Ridge, Tennessee generated electricity to
power a light bulb.
On June 27, 1954, the world’s first nuclear
power plant to generate electricity for a power
grid started operations at the Soviet City of
Obninsk.
The first full scale power station in Calder Hall in
England opened on October 17, 1956.
As of April 23 2014, there are 437 nuclear power
reactors operating in 31 countries.

9. The ONLY erected commercial nuclear
power station within the ASEAN countries.
It sits at the tip of a 389 hectare protected
land at Napot Point, Morong, Bataan.
The BNPP is a Westinghouse Pressurized
Water Reactor Nuclear Power Plant, the
most popular reactor design in the industry.
It took 10 years to construct and has been on
preservation mode since 1986 at a cost of
Php40 to Php50 million a year.

10. Advantages of Nuclear Power
Plants
Relatively Low Cost
Nuclear energy is cost-competitive and generating
electricity in nuclear reactors is cheaper than
electricity generated from gas, oil and coal.
Synergistic Energy
Nuclear power plants provide stable amount of
energy. They can work synergistically with other
energy sources since energy from power plants can
be lowered or cranked up high when required.
11. Advantages of Nuclear Power
Plants
High Density
The amount of energy we get from nuclear fission is
ten million times better than the amount we get from
burning fossil fuel such as oil and gas. This means
that a power plant can get a lot more energy from
basically the same amount of matter.
Sustainable (and Low Pollution)
By definition, nuclear energy is a non-renewable
energy source; however, it is sustainable by the use
of breeder reactors and fusion reactors.
The environmental effects of nuclear power are
relatively light compared to other energy sources.
12. Disadvantages of Nuclear Power
Plants
Accidents
No matter how careful and organized our plant
operators are there’s still a chance for human
error. Even the best technology and computer
systems have glitches and these little errors
could cause great damage not only to the
nuclear plants but also to the environment and
life itself just like what happened in Three Mile
Island (1979), Chernobyl (1986) and Dai-ichi,
Fukushima, Japan (2011).
13. Radioactive waste
We are exposed to radiation everyday but too
much absorbed dose of radiation can cause cell
death, cancer induction and even genetic damage
that could affect future generations.
If the radioactive wastes are not disposed of
properly, they can cause long term damages to the
environment and life itself.

15. Disadvantages of Nuclear Power
Plants
Nuclear weapon proliferation
Fissile materials used/produced/processed
in nuclear power plants can be used in
creating nuclear weapons.
16. Nuclear Weapons
Explosive devices that derive their
destructive force from nuclear reactions,
either fission (atomic bomb) or a combination
of fission and fusion (thermonuclear weapon
or H bomb).
17. Two types of Nuclear Weapons
Fission weapons or
atomic bombs
Thermonuclear weapons
or hydrogen bombs

19. Advantages of Nuclear
Weapons
War Deterrence
Nuclear weapons are the ultimate form of
deterrence as no enemy can hope to defeat a
nuclear weapon power without massive losses to
itself.
Smaller nations can stand a chance of defending
themselves against larger nations that have more
money and military capabilities when the have
nuclear weapons. This can increase the peace
and make it less likely that certain nations will get
bullied or invaded.
20. Advantages of Nuclear
Weapons
Low Cost Insurance against Aggression
Building massive army, fighters and armor cost a
massive deal of money. Compared to that, building
a few nuclear bombs is quite cheap especially for
countries who have operating nuclear power plants.
21. Disadvantages of Nuclear Weapons
Radiation Accidents
Terrorism
Environment Disaster
Finishing mankind off
22. Nuclear Disarmament
Nuclear disarmament refers to both the act
of reducing or eliminating nuclear weapons
and to the end state of a nuclear-free world,
in which nuclear weapons are completely
eliminated.
23. Former Secretary Henry Kissinger says there
is a new danger, which cannot be addressed
by deterrence: "The classical notion of
deterrence was that there was some
consequences before which aggressors and
evildoers would recoil. In a world of suicide
bombers, that calculation doesn’t operate in
any comparable way".
George Shultz has said, "If you think of the
people who are doing suicide attacks, and
people like that get a nuclear weapon, they
are almost by definition not deterrable".
