I strongly agree with Dewey.
I have found over the past few days that my university prefers that I speak publicly about the incident. The public wants more information. Some of the interview that I have done have been silly. NPR asked me to describe a non-normal natural disaster that could damage the reactors in Illinois after I said that the GE designs (4 in Illinois) now have been shown to survive a magnitude 9 earthquake which is greater that what we have observed in the New Madrid fault historically. What is a non-normal natural disaster? Something other than earthquake, fire, flood, tornado, hurricane.
Describe exactly what happened.
The tsunamis played a major role in the event. Took out diesels at Dewey stated.
Backup generators were flown in but they had some issues (everyone reports that the plugs did not fit). It could not have been due to the plugs not fitting as someone would have cut the wires and wired together plugs, etc. The likely issue is that some of Japan runs at 50 Hz and some of Japan at 60 Hz. I can't believe that it would be just the plug. This would not happen in the US.
Chernobyl, explain delayed vs prompt critical. Explain the Carbon moderators in the core. Explain the difference in amount of carbon vs the amount of Zr cladding (approximately 1 mm OD tube). This is what oxidizes (burns) in the reactor or spent fuel pool for that matter. It does contain the fission products. The UO2 does not burn.
If you are clear, the majority of people will understand what you are describing.
Give your contact information.
I have been answering hundreds of emails from the public after these appearances. Many of the questions are similar and you can cut and paste. Respond to questions from everyone. It makes everyone feel that you care about them. When they respond to your question with a thank you, respond with a you're welcome. Offer to answer any questions that they have in the future.
I have yet to receive an email from a rapid antinuclear person. They have been from the general public who want to understand what is happening.
This is just on top of Dewey's excellent advice that I have left in below.
If you are going to comment publicly, make sure that you have the most up-to-date information and that you understand what has been released. There have been multiple reactors that have been described as having problems.
Explain how much energy that we generate from nuclear, here in Illinois it is 50 percent. Explain that it would be nearly impossible to replace it immediately and we really would not want to as it provides extremely stable (no standard brownout times in Illinois) supplies in times of high demand.
I have been using it to explain the spent fuel problem as well. Describing reprocessing, long term storage and explaining why I think that storage in populated areas is not as good of an option as putting it in imperfect repositories such as WIPP or Yucca Mtn and that they should contact their representatives that they want safe nuclear power with the waste taken care of by the DOE as required by law.
