I think it was a steam explosion.
Not a “nuclear” explosion.

We want our own nuclear disaster!
Renewable Energy
Good or bad?
Nuclear Power – Savior or Devil?
Three-Mile Island
Chernobyl
Fukushima
TMI-2

40 years
Vasanth Prabakar 7:04 PM
The first impression is the best impression!
Lee Wright 7:08 PM
Chernobyl is a different design from TMI-2.
Chernobyl had no effect on USA.
Fukushima
We study the worst weather for the past 100 years in an area where we build a plant and DESIGN against it.
Spain has at least one nuclear plant.
Japan has many accidents but keep them secret.
China MUST have had nuclear accidents, but apparently keep them VERY secret.
India
Radioactive waste can be compacted and controlled
Gerard Arbat 7:13 PM

but people are over-terrified about this aspect.
Luckily, the ocean can dilute the radioactivity.
RosAtom

Recycle waste

Oil fumes kill people
Sun/wind nears lots of land, kills animal habitats
First responders
Sarcophagus (sar CAHF uh gus)
Concrete block over the plant
gist (jist)
Speaker believed in renewable energy.
Solar farms need space but kill animal habitats.
Wind mills kill birds and bats
and need lots of land
Solar panels will become waste.
Carbon dioxide.
Propaganda, advertising
friends’ opinions
Politics
Gerard Arbat 7:19 PM
sun and wind look clean
Lee Wright 7:19 PM
Marie was probably Marie Curie.
He looked at the facts objectively
and decided that nuclear power is actually the BETTER choice but we eshew (avoid) it psychologically.

Nuclear power doesn’t advertise much. I don’t understand WHY.
Reactor
Nuclear power is complex and hard for people to understand.
Physicist (FIZZ uh sist)

Lee Wright 7:23 PM
Nuclear power is viewed favorably in Russia.
Not in Spain
Not in Germany
Not in Japan
uranium
isotopes (ICE uh TOPES)
neutrons
different weight
< 1% in nature
Vasanth Prabakar 7:24 PM
Don't they want those countries to become rich?
Lee Wright 7:24 PM
Must enrich it to 3 to 5% for a power plant
Vasanth Prabakar 7:24 PM
Can't they invade?
Lee Wright 7:24 PM
Must enrich to 50% for bombs
Nuclear submarines use 95% enrichment to keep the reactors small.
Not expensive like gold or platinum

Uranium is very dense/heavy, like lead. So it is good to make bullets from, like lead.
So "spent uranium" (radioactive) is used to make armor-piercing bullets to shoot tanks.

Nuclear plants have HIGH security.
Fences, barbed wire
X-ray machines
metal detectors
cameras
infrared
motion detectors
empty areas between two tall fences, both with barbed wire
Hand biometrics

drug footprint
Lee Wright 7:35 PM
Radiation is undetectable and invisible. Can kill quietly
We pass through radiation detectors when leaving the plant as well.

Lee Wright 7:35 PM
Russia was the FIRST country to use polonium to secretly kill someone.
Russia didn't tell other countries about Chernobyl for days!
We all knew something was abnormal but USSR kept saying "No problem".
Japanese culture at the time of Fukushima was to HIDE flaws
to "save face"
Ukraine, Belarusa
Russia
Disasters make heroes.
People must volunteer to do suicide missions.
Use old, single people.
Old people are less damaged by radiation that younger people
Younger people think they are inviincible.
We drafted 18-year-olds to fight in the war.
easy to indoctrinate
glory!!!!
"Blaze of Glory" song
WW II
Bold pilots die young
Old pilots were cautious.
Should we use solar at all?
On a large scale, no.
On a smaller scale, yes.

Watches, calculator, traffic lights, have solar-powered backup sometimes.
Contingency source of energy.

hedge the risk
Lee Wright 7:50 PM
Spacecraft can use solar-power for an infinitely long period of time if they are close to a star.
Diversity in England
Diversity in energy

seawater is corrosive
sea levels go up and down

solar water heaters for hot water
Run your car on water alone! (scam)
not cost-effective
