"The INES Scale is a worldwide tool for communicating to the public in a consistent way the safety significance of nuclear and radiological events.
"Just like information on earthquakes or temperature would be difficult to understand without the Richter or Celsius scales, the INES Scale explains the significance of events from a range of activities, including industrial and medical use of radiation sources, operations at nuclear facilities and transport of radioactive material...."
The four-page pdf document explains what sort of events are described for each of the seven (eight, counting the zero, or 'nothing happened') levels of severity: and gives brief definitions of the terms.
Putting THREE MILE ISLAND! THREE MILE ISLAND! in Perspective
The reactor failure at Three Mile Island, back in 1979, was very scary, very expensive, and not, in the Lemming's opinion, all that dangerous to people who didn't have money invested in the power plant. Not compared to, say, housing developments built on toxic waste dumps. And that's another topic.Still, the Lemming's gotten the impression that for some folks, particularly chronic journalists, Three Mile Island is spelled "THREE MILE ISLAND! THREE MILE ISLAND!"
Yes, the Three Mile Island accident was the worst nuclear power plant malfunction in American history to date. But, expensive and scary as it was, the containment building held - and there doesn't seem to have been a serious health risk involved. Unless someone decided to go inside in his skivvies. ("Backgrounder on the Three Mile Island Accident," NRC)
Or maybe everybody in Harrisburg and York, Pennsylvania, died horribly; and those space-alien, shape-shifting lizard people have kept us from finding out. You probably don't know anybody in Harrisburg, Pennsylvania: YOU SEE? THAT PROVES IT!!
Quite a few news sources - the ones that the Lemming's seen, anyway - seem to have calmed down quite a lot since the '80s. As far as THREE MILE ISLAND! THREE MILE ISLAND! is concerned, anyway. Even so, there still seems to be quite a bit of emphasis on that 1979 overheated core: that may have done more damage to the bank balances of a few individuals, than anything else.
Moving on.
And taking a more 'global' approach:
It looks like the Soviet Union won the nuclear disaster race in one category. The top two occurred at soviet-era reactors. The winners, looking at this as a contest, so far are:
- Category: People and Environment
- Level 7: Chernobyl, 1986
- Widespread health and environmental effects
- External release of a significant fraction of reactor core inventory
- Widespread health and environmental effects
- Level 6: Kyshtym, Russia, 1957
- Significant release of radioactive material to the environment from explosion of a high activity waste tank
- Level 5: Windscale Pile, UK, 1957
- Release of radioactive material to the environment following a fire in a reactor core.
- Release of radioactive material to the environment following a fire in a reactor core.
- Level 7: Chernobyl, 1986
- Category: Radiological Barriers and Control
- Level 5: Three Mile Island, USA, 1979
- Severe damage to the reactor core.
- Level 5: Three Mile Island, USA, 1979
INES Scale: What Those Numbers Mean
Here's a sort of short, and not-terribly-informative, rundown of what those seven levels of severity mean.- Major Accident
Level 7 - Serious Accident
Level 6 - Accident with Wider Consequences
Level 5 - Accident with Local Consequences
Level 4 - Serious Incident
Level 3 - Incident
Level 2 - Anomaly
Level 1 - No Safety Significance
(Below Scale/Level 0)

"INES," Fukushima's Reactors, and Getting a Grip
As for Japan's Fukushima power plant: depending on who you ask, yesterday it was at level 6, or 5. Maybe 4. (CNN)As the Lemming recalls, the Japanese government's assigning a level 4 to Fukushima was
- After
- The earthquake
- Which doesn't appear to have seriously damaged the reactors
- The tsunami
- Which took out the primary cooling system
- The earthquake
- Before
- The backup system ran out of power
- Other systems failed
- Explosions started happening at intervals
Doesn't the Lemming Care About the Horrors of [insert phobia]?
The Lemming, as this blog's name suggests, is "apathetic." That's been discussed before. The Lemming's "apathy" means not caring - hysterically, irrationally - about the "right" things.Nuclear power plants are dangerous. So are those using oil, natural gas, or coal for fuel.
There's no such thing, in the Lemming's opinion, as a "safe" technology. (March 12, 2011) Even knapping flint is risky. What's changed in the last million years or so is the scale of problems we're dealing with.
Happily, along with dangerous technologies like fire, sharp rocks, scissors, and nuclear reactors: we've also developed increasingly powerful and sophisticated societies. We didn't all die of manure pollution in the 18th century - and I'm pretty sure that the folks in Japan will deal with what's happening at Fukushima.
And if they don't, we'll all have learned something.
Now, about caring: Yes, the Lemming cares.
It's possible, maybe likely, that tens of thousands of people were killed last Friday. That's a terrible loss. Many more are facing sub-freezing temperatures and snow today. That's not good, either.
But the Lemming won't make the situation better by wringing his paws and agonizing. The Lemming can give a link back to a list of probably-okay charities, assembled for the Haiti disaster. (The list is what was assembled: with one exception, the charities had been around for a while.)
Most of the organizations on that list are global, or connected to international outfits: and although Japan is a major nation - this week, they might be able to use some financial help. Just a thought. Here's that link:
- "Haiti: About the Earthquake, Relief, and Related Topics"
(January 15, 2010)
So, yes: the Lemming cares.
