Are you concerned more about the development of nuclear power after the Fukushima
nuclear disaster?
I have carried out a survey among 150 Hong Kong
citizens(60 students,30 teachers and 60 other citizens). Here is
the result.

Q:How does a nuclear power plant generate electricity?
Wong Kamyui@Fukushima nuclear power
plant

Mr. Lui(Worker of the power plant)
A nuclear power plant = a steam power plant that is fueled by a radioactive element, like uranium.

Q:How much of the world's electricity comes from nuclear power?

There are still a lot of nuclear power plants in
the world. Mr. Lui(Worker of the power plant)

Should we
continue to
develop
nuclear
power?
12
Yes56%
No44%
In the view of Fukushima nu-clear disaster, is it still worth
developing nuclear power?
The development of nuclear power is controversial.Lee Yuk Wa

HOW THE JAPANESE GOVERNMENT THINKS ABOUT NUCLEAR POWER…
14
1.Won’t produce
greenhouse gases
E.g. sulphur dioxide ,
carbon dioxide , nitrogen
oxides.etc
->Reduce air pollution
15
2.Cheaper nuclear
fuels costAmong all the costs of
nuclear generation, the cost
of fuels occupy with a lower
proportion.
16
3.Small in size but
large amounts of
energyMillion times larger than
that from the chemical
energy->Save money
17
4.Reduce our reliance
on fossil fuelsFossil fuels is ranked the top
3 of global energy consumption
(87.04% of the world's energy
consumption)
18
What we have done after 311:① Set up a new
department to regulate the nuclear power generation.
② Limit the exports of some products in the areas aff ected.
③ Install a new emergency generator.
④ Set the emergency evacuation orders.
19
HOW THE JAPANESE CITIZENS THINK ABOUT NUCLEAR POWER…
20
1. The used nuclear fuel is radioactive . It must be sealed up and buried for thousands of years to allow the radioactivity to die away.
21
2. For all that time it must be kept safe from accidents. This is difficult.
22
$ $
3. Comes with an enormous price because it takes strenuous researches , comprehensive safety facilities and manpower.
23
4. Nuclear power generation will produce a lot of heat . This needs plenty of water to cool it down . The sea water temperature will increase and thus the growth of algae, resulting in large amounts of carbon dioxide and the marine life will die.
24
5. Requires a lot of flat land to build nuclear power plants.
25
Lower produc-tion cost
17%
The absence of greenhouse gases
25%
Great storage of nuclear resources
7%
The fuel is smaller in size
but can generate larger amount of
energy21%
Reducing the re-liance on fossil
fuels 30%
Why is it worth developing nuclear power in Japan? (Choose the most
significant reason)
26
Nu-clear
power is
harm-ful to
human body 48%
The used nuclear fuel is radioac-tive11%
It re-quires a lot of
flat land for
build-ing nu-
clear power plants12%
Lack of mod-ern
tech-nology
14%
The use of
nuclear power comes with an enor-mous price15%
Why is it not suitable to develop nuclear power in Japan? (Choose
the most significant reason)
27
WHAT IF THERE IS ANUCLEAR LEAKAGE?!
28
Radioactive dust
->released into the atmosphere
->causes cancer on human body
Health
29
Food Contamination-Japanese didn’t have food to eat-Export income dropped
30
Residents should be alienated from the nuclear disaster area.->They don’t have a place to live
さようなら !(GOODBYE)
31
Q:What do you suggest the government to do?
Wong Kamyui@Japan
32
Stop using nuclear power!!!Use other renewable powers
instead!!!
(It is the opinion from most of the Japanese forum.)
Mr. Chung(a Japanese)
33
Advanced technology for keeping
the used nuclear
fuel 24%
Better emergency
power generation equipment
5%Equipping
with water tanks to provide cooling water
7%
Planting more sun-flowers to reduce nu-clear radia-
tion5%
Using other
re-new-able
powers instead
(e.g. wind , solar)58%
Others1%
What is the most urgent action that the Japanese government should take to reduce the negative im-pacts of the nuclear disaster?
-better development plans-better designs of nuclear power plants
34
ConclusionFrom the project, we found that:
People concern more about the development of nuclear power
The development of nuclear power is controversial
Still a lot of nuclear power plants
Nuclear is not safe enough
35
We think:Tidal, wind or solar powers can
be used to guarantee people’s safety.
Less electricity should be consumed, fuel used for generating electricity can be reduced.
Safety are more important.
