Dangerous
wastes from these facilities…

Need Site for Safe Disposal
Nuclear energy, energy from
the nucleus of radioactive atoms, is being used for several purposes by various
industries such as
Nuclear power plant (to
produce electricity, first one was built in 1957 in the
Nuclear Weapon industry
Medicine and
Research Facility.
The main problem all of these
industries are facing at present is, to be able to find an appropriate and safe
site to dispose off their nuclear waste, also called radioactive waste which
has been accumulating since past forty years. They have been storing it temporarily
at their facilities. 30 tons/year is being produced at each of the 104 power
plants in US, total amount from all of these
industries has reached an amazing, unbelievable amount, about millions of tons
waiting for disposal. They have been classified as Low level which stays
dangerous for about 300 years and the high level waste that stays for tens of
thousands of years.
The waste generated at these
facilities is much different than the regular or the toxic waste produced
elsewhere which can be either put in the landfills or incinerated or recycled.
None of these are the options for disposing off the radioactive wastes. The
reason being they emit very dangerous radiations and remains so far thousands
of years; it poses problems not only for the present generation but for future
generations as well. The radiations can cause skin burns, cancer or mutations
of genes or other health problems or even death.
We therefore have to be very
careful in dealing with this important social issue. .
When, where and how to dispose it is a difficult
environmental dilemma
Department of Energy(DOE)
and other Research Scientists have been studying several options as given in the following website
Such as
Ocean dumping and Land burial. Space dumping is also being considered.
The various criteria are
taken into account such as geological disturbances (volcanic activity, earth
quake, etc), the depth of ground water, isolated area and containers to be used
for packaging- should be very strong and stable for thousands of years without
any leakage of radiations.
Two sites have been chosen. One in
It is planned that some 850,000 drums (containers) will be
stored in the US$1.8-billion pilot plant. It has already started receiving shipment.
Other one is in
This is the aerial view of
the site for disposing the hazardous waste, to be buried deep underground. It
is considered to be geologically safe
and safe from intrusion of ground water.

You are one of the very well known Public Policy
Analyst and a scientist, so have been appointed as a representative of your
community by the Environmental Protection Agency to discuss about the benefits
and drawbacks of these sites. Give your opinion about solving this problem. Being given a responsible position, you have to be well
educated as to know all the alternatives available, read the resources for
important information and start your important task as a group. Good Luck..
Working in a group of 3, your task consists of two
main parts:
A WRITTEN PAPER
Submit a typed paper about
3-5 pages long. It must have a cover page showing the Title, Date, Teacher’s
name and the names of all the Group members. You must include bibliography at
the end. You have to follow the Public Policy Analyst Model (PPA) to complete
your paper; the steps of this model are given below. You will the information
gathered by following these steps to complete the task.
1-Define the problem
2-Gather Evidence of the
Problem
3-Identify the causes of the
problem
4-Evaluate the existing
Policy
5-Develop Public Policy
Solution
6 Selecting the Best Policy
after analyzing Benefits and Risks
You may also make a power
point presentation using at least one slide for each of the work sheets and submit
the floppy disk.
You will be given 5-7 min of
time for oral presentation in front of the class about your findings on this
topic. All the members of the group should be able to answer questions about
your findings.
1. Each member of your group
must be assigned a job for appropriately completing your project. In order for
you to understand the problem, read the four Hyperlinks listed in the resources
section of this TIPS Web Quest.
Each member may read one (or two) of these and discuss with each other, noting
down the important points of your interest. You may also read more references
as you work on your paper if you need extra information about the topic.
2. There are 6 work sheets, one for each of the 6 steps of PPA model.
You will need these worksheets in order to complete your written report.
Find these at the end of each of the
following PPA hyperlinks. Read these carefully. To get to the first worksheet
click on the hyperlink, “Define the Problem”, you will see a yellow screen with
some information, read this part, you may click on the “See the example” given
to help you in completing your worksheet. You will see two work sheets for each
step, but you can type your answers only on one of them (MSWORD), click on it
and answer the questions 1-4.
2-Gather Evidence of
the Problem
3-Identify the causes
of the problem
4-Evaluate the Existing
Policy
5-Develop Public Policy
Solution
6-Selecting the Best
Policy after analyzing Benefits and Risks
3. Follow the same steps to complete other 5
worksheets. For every worksheet there is an example given to help you complete
it for your problem. You will use your worksheets to complete the task. These
are your research tools. Be sure to access the web sites given in the resource
section. You may use text material and journal articles as well.
4. Now, you may start typing your paper making
sure to follow the proper steps using your worksheets and other resources
listed below. The completed report should answer the following questions.
A) What is the main problem faced by an industry
using nuclear energy? (Worksheet 1)
B) Show the Proof that it
exists and the reasons that contributed to its existence (Worksheets 2 and 3)
C) List
various options available for the disposal of such radioactive wastes.
D) Discuss
the benefits and risks involved with these options. (Worksheet 4)
E) Evaluate
the options for their Effectiveness and Feasibility (worksheet 6)
F) Can your policy be easily enacted by the Govt.
agencies? Will it be safer for the present community as well as for future
generations? (Worksheet 5)
Use the following websites to help you research your
paper:
(These two can be used as search engines to look for
various sites)
( WIPP site)
http://www.nrdc.org/bushrecord/nuclear.asp
http://www.nuc.umr.edu/~ans/QA.html
(This site explains the need for nuclear energy, its
uses and risks compared to other sources, waste disposal, cost analysis etc.)
http://www.history.rochester.edu/class/EZRA/
(This paper gives the location and statistics of
total KWhrs of energy produced by Nuclear Power Plants in various states
including
the 3 in NY)
http://www.nei.org/index.asp?catnum=1&catid=14 Gives a very good description about nuclear energy,
including the public policy issues.
Federal legislation mandates a centralized geologic repository. The
Nuclear Waste Policy Act of 1982 and its 1987
amendments require or authorize the U.S. Department of Energy to locate, build
and operate a deep, mined geologic repository for high-level waste;
1. locate, build and operate a
"monitored retrievable storage" facility;
2. Develop a transportation
system that safely links
To accomplish this, the Act
established the Office of Civilian Radioactive Waste Management within DOE,
headed by a presidential appointee.
(It describes the Low-level Waste management).
