Nuclear Power Webquest

Introduction

The fifth energy source considered in this course is nuclear power.  As you learned in my presentation on 7 October, nuclear fission is a major form of energy - accounting for 22% of electricity generation in the United States.  Nuclear plants are found worldwide, including 133 separate facilities in the United States.  As I mentioned, however, no new nuclear plants have been constructed in the US since 1974.  Concerns over safety have led to serious restrictions in deployment over new plants.  Moreover, many of the plants constructed in the 1960s are reaching the end of their projected life spans.

Many people believe that concerns over nuclear power are really unwarranted, based on the large-scale safety record of existing plants.  Those people believe that nuclear fission continues to hold great promise as a viable alternative to direct combustion of fossil fuels to generate electricity.  Others believe that it has limited applicability and the environmental risks far outweigh the benefits.


The purpose of this webquest is to enable teams of students to learn more about nuclear power, and determine its potential to serve as a significant source of "clean" energy in the future.


Task

The teams assigned to this webquest are to review the websites listed below.  Students in those teams are to answer the following questions:
  • What evidence supports the idea that products of nuclear fission can provide a significant proportion of energy demand in the future?
  • Does everybody agree with that evidence?  If not, explain.
  • My presentation suggested that nuclear energy has been best developed in industrialized locations such as North America, Europe, and Asia. 
    • Can energy production from nuclear energy be enhanced in those areas?
    • Can energy production from nuclear energy be developed in those areas (e.g., South America and Africa) where it has not yet been developed?
  • What environmental problems does nuclear energy pose?  Are those problems real or exaggerated?
  • What social / political problems?
  • Do any laws or regulations prevent the deployment of nuclear energy in the US? Other industrialized countries?  Non industrialized countries? 
  • Are any countries seeking to shut down all their nuclear plants?  If so, what arguments are being used to justify that course of action?  What other forms of energy are they planning to use instead?
  • What is the life expectancy of nuclear energy reserves?
  • What is nuclear fusion?  Does it old much promise for our own energy needs in the next 30-40 years?
Process

On 22 October, student teams will conduct a webquest using the following websites:
Of course, you may work outside of class as a team to further research the topic, generate a synthesis, and formulate a presentation.

On 22 October, student teams assigned this topic will each give a 20 minute Powerpoint-based presentation in which they will answer the questions.

Evaluation

Students will be evaluated using the following rubric.  The grade will reflect both an individual and a team performance.
