I'm sure that's a great comfort to the former residents of Chernobyl and all those living in the water table area surrounding the nuclear facilities at Hanford, Washington, Three Mile Island and any other contaminated area. :roll:Originally posted by: ntdz
You do realize that nuclear power plants don't "explode" when things go wrong, right?
A little info from the NRC
For some more perspective, see the list of civilian nuclear accidents. I'll skip those from the '50's through the '90's and cut to those since 2000.NRC Incident Reports

NRC ASP Analysis Program
- Three Mile Island Unit 2 (28-Mar-1979)
The NRC established the Accident Sequence Precursor (ASP) analysis program in 1979 in response to the Risk Assessment Review Group report (see NUREG/CR-0400, dated September 1978). The primary objective of the ASP Program is to systematically evaluate U.S. nuclear power plant operating experience to identify, document, and rank the operating events that were most likely to lead to inadequate core cooling and severe core damage (precursors), if additional failures had occurred. To identify potential precursors, NRC staff reviews plant events from licensee event reports (LERs), inspection reports, and special requests from NRC staff. The staff then analyzes any identified potential precursors by calculating a probability of an event leading to a core damage state.
(ref NRC Commission Document SECY-05-0192 Attachment 2)
A "significant precursor" is an event that leads to a conditional core damage probability (CCDP) or increase in core damage probability (CDP) that is greater than or equal to 1×10-3. In other words given that the precursor event has occurred, the probability that a subsequent failure will cause core damage is >=0.001.
As of 24-Oct-2005 the "significant" precursor events (i.e. the worst category) were (listed from highest probability of occurrence 1 to lowest probability of occurrence 0.001):

Considering the meaning of the word, ACCIDENT, and ignoring the added threat of an intentional terrorist attack, remember, it would take just ONE serious nuclear event to kill more people than than died on 9-11, sicken a lot more and render a significant amount of real estate uninhabitable forever.List of civilian nuclear accidents

2000s
- February 15, 2000 ? The Indian Point nuclear power plant's reactor 2 in Buchanan, New York, vented a small amount of radioactive steam when a steam generator tube failed. No detectable radioactivity was observed offsite. Con Edison was censured by the NRC for not following the procedures for timely notification of government agencies. Subsequently, Con Edison is required by the NRC to replace all four steam generators. NRC Information Notice 2000-09
- February 9, 2002 ? Two workers were exposed to a small amount of radiation and suffered minor burns when a fire broke out at the Onagawa Nuclear Power Station Miyagi Prefecture, Japan. The fire occurred in the basement of reactor #3 during a routine inspection when a spray can was punctured accidentally, igniting a sheet of plastic.
- April 10, 2003 ? Radioactivity leak in Paks Nuclear Power Plant, Hungary. Rated INES-3.
- April 19, 2005 ? Sellafield, UK. Twenty metric tons of uranium and 160 kilograms of plutonium dissolved in 83,000 liters of nitric acid leaked undetected over several months from a cracked pipe into a stainless steel sump chamber at the Thorp nuclear fuel reprocessing plant. The partially processed spent fuel was drained into holding tanks outside the plant.
- 2005 ? Dounreay, UK. In September, the site's cementation plant was closed when 266 litres of radioactive reprocessing residues were spilled inside containment. In October, another of the site's reprocessing laboratories was closed down after nose-blow tests of eight workers tested positive for trace radioactivity.
- July 25, 2006 ? An electricity fault prompted shut down of the Forsmark Nuclear Power Plant, Sweden. Several problems occurred during the shut-down phase. While Swedish Nuclear Power Inspection authority rated the incident INES 2, Lars-Olov Höglund, expert familiar with design of the plant, stated it was the most serious nuclear incident since the Chernobyl disaster and it was pure luck that prevented a meltdown.
Knowing that, now, would you rather take every precaution to prevent such a catastrophy before it happened or live with the foreseeable results and your own conscience AFTER the fact... that is, if you weren't one of the victims?
If you're not in a position to make such decisions for our society, and remembering how flawed this and previous adminstrations have been about monitoring our air, water, food supply, chemical and nuclear plants and other critical resources, what would you think about those who decided to go forward with more nuclear facilities AFTER the fact of such a nuclear event? Do you really trust those who serve a money driven government and economy to choose wisely 100% of the time? :shocked:
