NUCLEAR
TECHNOLOGY What is Nuclear Tech.? Nuclear technologies involves a medium sized group of things.

-Fission (the now)
-Fusion (the future)
-Explosives (The original) Fission - taking fissionable isotope of an element and tearing it apart. Adding extra neutrons can make a chain reaction so more energy will be produced from the initial reaction. Nuclear: Dealing with the involvement of the nucleus of an atom Technology: Applying scientific know how into 'practical' machines for 'practical' use. Pros Cons - Creates Massive
amounts of energy

- Cleaner than most
conventional methods
in most ways. - Needs energy to start
reaction.

- Radioactive waste.

- Very deadly if something
goes wrong. The Energy gained from a nuclear reaction is from matter "lost" in the reaction. This is also know as the deficient matter. The equation to calculate this is E=mc 2 Fission! Nuclear Technology: Machinery using energy created from splitting or combining atoms. Smoke Detectors are the most common piece of nuclear technology to many people. Fusion! Fusion- opposite of fusion; taking two atoms and putting them together. Most commonly 2 Hydrogen to 1 Helium Pros Cons -More Energy
-Hydrogen is
very abundant
-Possibly
bring back
airships! -Deadlier failures
-Harder to
control
-Nuclear waste Disasters Nuclear
Explosives When things go wrong, they go very wrong. Sometimes the reaction gets out of hand and the energy levels surge which destroy the containment chamber. After it has destroyed the containment chamber it releases mass energy and radiation to the surrounding area. Pripyat Deuterium is an
isotope of hydrogen
with one neutron
while tritium is a
hydrogen isotope
with two neutrons. Like the silly humans we are, the first thing we thought to make with this power is a weapon. It started with the Atomic Bomb created through the Manhattan Project which involved America and Canada. Atomic Bombs were
all about fission. Currently we now have Hydrogen Bombs.
We call them this because they use hydrogen to cause a fusion reaction for a bigger boom. H-Bomb work by causing a
fission reaction to jump start
the fusion explosion. The first fusion bomb had a
bigger blast radius than expected
because it starting fusing other things This is the Hiroshima Aftermath. Only twice has a nuclear weapon been use in war. Both during WWII by The United States of America against Japan Only about half the deaths from
a nuclear explosion are from the
initial blast. The other half are from
the fallout that irradiates and slowly
kills and/or deforms its victims Chernobyl Reactor 4 100 rads = 1 Gy -1 Gy nothing noticeable, only blood changes
-1-2 Gy in less than 1 day Causes ARS
-2-10 Gy over a few hours causes serious sickness
-more than 10Gy will usually cause death Gy stands for Gray and it measures Energy absortion. Created by Zach Selders And
Charlotte Prince Recap! Fission -energy produced
by splitting atoms Fusion- energy produced
by combining atoms Explosives- Atomic
bombs were developed
during WW2 and used
fission to
create energy. Hydrogen bombs were
developed and use
fusion to make
a bigger boom. Disasters happen when
a reaction gets our
of control. 3 major disasters:
Pripyat
Chernobyl
Fukushima Daiichi Plant Thanks for watching our Presentation!
