Subject: New Macromedia Flash web site presents U.S. nuclear reactor
  systems in animated format

March 7th, 2005


Re: New interactive animations show the inner workings of U.S. nuclear power reactors.

To help people understand nuclear power, the author has created a web site with animated drawings of the two types of nuclear reactors in use in the United States: Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs).  There is an animated overview for each type and, for the PWR, there is also a view showing a typical steam generator arrangement.  For the BWR, there is a reactor core flow diagram.

All four animations are based on common, well-known industrial illustrations of Westinghouse and General Electric reactors.  The program may be freely copied if left unchanged.

Here is the URL for these new animations:

This author would also like to gratefully acknowledge Synthesis/Regeneration: A Magazine of Green Social Thought, which included my essay about the dangers of tsunamis and nuclear power plants in their March issue (page 4).  Other places the Tsunami article can be found include:

These sites have also either posted the article, or at least a link to one of the other postings, and usually a description as well:

You'll also find the essay mentioned at the web site:


To see what can go wrong at these reactors, please view my previous animation, called ONE BAD DAY AT SAN ONOFRE, about an internal memo sent by the plant's management to all employees in December, 2004 regarding this author.  ONE BAD DAY includes a graphic depiction of various natural (and unnatural) disasters which might befall the facility (move your mouse over the icon ONE BAD DAY, on the left, to view the animated destruction of the facility):
