Japan’s Nuclear Reactors Are Doing What They’re Supposed to in an Emergency

I can’t believe I’m saying this but look at this New York Times article on it here. 
From today’s WSJ is this:

The core of a nuclear reactor operates at about 550 degrees Fahrenheit, well below the temperature of a coal furnace and only slightly hotter than a kitchen oven. If anything unusual occurs, the control rods immediately drop, shutting off the nuclear reaction. You can’t have a “runaway reactor,” nor can a reactor explode like a nuclear bomb. A commercial reactor is to a bomb what Vaseline is to napalm. Although both are made from petroleum jelly, only one of them has potentially explosive material.
Once the reactor has shut down, there remains “decay heat” from traces of other radioactive isotopes. This can take more than a week to cool down, and the rods must be continually bathed in cooling waters to keep them from overheating.
On all Generation II reactors—the ones currently in operation—the cooling water is circulated by electric pumps. The new Generation III reactors such as the AP1000 have a simplified “passive” cooling system where the water circulates by natural convection with no pumping required.
If the pumps are knocked out in a Generation II reactor—as they were at Fukushima Daiichi by the tsunami—the water in the cooling system can overheat and evaporate. The resulting steam increases internal pressure that must be vented. There was a small release of radioactive steam at Three Mile Island in 1979, and there have also been a few releases at Fukushima Daiichi. These produce radiation at about the level of one dental X-ray in the immediate vicinity and quickly dissipate.
If the coolant continues to evaporate, the water level can fall below the level of the fuel rods, exposing them. This will cause a meltdown, meaning the fuel rods melt to the bottom of the steel pressure vessel.
Early speculation was that in a case like this the fuel might continue melting right through the steel and perhaps even through the concrete containment structure—the so-called China syndrome, where the fuel would melt all the way to China. But Three Mile Island proved this doesn’t happen. The melted fuel rods simply aren’t hot enough to melt steel or concrete.

Amnesiatic Obama and His Short Memory

After wondering why it took two months for the usual cry of “gun control’ to come, after the tragic shooting of Rep. Gabrielle Gifford in Tucson, Arizona this past January, and even doubting that Obama actually authored the op-ed published in the Sunday, March 13, 2011 Arizona Daily Star, I am left completely flabbergasted reading the very first paragraph.

“It’s been more than two months since the tragedy in Tucson stunned the nation. It was a moment when we came together as one people to mourn and to pray for those we lost. And in the attack’s turbulent wake, Americans by and large rightly refrained from finger-pointing, assigning blame or playing politics with other people’s pain.”

All of the normal knee-jerk calls for gun control are contained in the piece, “enforcing laws that are already on the books,” “reward the states that provide the best data – and therefore do the most to protect our citizens,” “make the system faster and nimbler,” “porous background checks,” “more we can do to prevent gun violence,” and the inevitable “beginning of a new discussion.”

Seen it all before, heard it all before, nothing new.

And as usual, missed is that the system in place was defeated due to lax law enforcement in identifying a young man, mentally disturbed that received several passes from run-ins with law enforcement and a family that did not heed repeated warnings on his mental instability.

Nothing new in all of this, save that first paragraph quoted above.

I realize actually performing in the office he was elected to in 2008 is not all the important to Barack Obama, as he spends more time on the golf course and on vacation than pretending to lead the nation, but doesn’t he ever receive news alerts while off playing on our tax dime? Doesn’t he at least have a radio on his golf bag?

How can anybody, with any pretense of a straight face come forward now, a mere 2 months after the tragic shooting/murder and say, “And in the attack’s turbulent wake, Americans by and large rightly refrained from finger-pointing, assigning blame or playing politics with other people’s pain.

Within minutes, it seemed, all were heard were attacks on Sarah Palin, Rush Limbaugh, conservatives in general and every faction of talk radio. Words ever spoken by any on the right were twisted into appearing like calls for violence. Ads featuring a target sight were manipulated to claim as threats of bodily harm.

Anything the left could twist was blasted as uncivil, vitriolic and violent, ignoring the even stronger tactics Democrats are noted for.

Obama himself came out in his January 13, 2011 speech at the memorial for the victims saying, “It’s important for us to pause for a moment and make sure that we’re talking with each other in a way that heals, not in a way that wounds,” indicating he must have been aware of the vitriol and rhetoric emanating from his party cohorts.

Of that speech, the New York Times published, “Mr. Obama called on ideological campaigners to stop vilifying their opponents. The only way to move forward after such a tragedy, he said, is to cast aside ‘point-scoring and pettiness’.”

From Rachel Maddow to Keith Olbermann, the rhetoric continued as fingers were pointed towards any on the right, knowing full well that it was the work of the deranged mind of a young liberal.

No cheap shot was too much, no casting aspersions against conservatives was over looked. Day in and day out for weeks, Democrats and their supporters pulled every dirty trick they could to cast a dark shadow over political opponents.

And now, Obama’s name is attached to an op-ed allegedly written by him, or for him claiming, “And in the attack’s turbulent wake, Americans by and large rightly refrained from finger-pointing, assigning blame or playing politics with other people’s pain.

Either he has totally lost what little mind he had and slipped into a state of amnesia, or he is totally dishonest in already going for revisionist history to make Democrats appear much better than they are for the 2012 elections.

Another reason could be, since he specifies “Americans by and large,” is that he doesn’t consider his party, liberal Democrats and their supporters as “Americans.”

Whatever the reason, that it would even be tried this soon after all of the rhetoric was thrown about just proves to me he is unfit for the office he occupies.

We need a leader in Washington D.C., we need someone at the helm knowing what he or she is doing and that wants to see America thrive and regain her greatness.

What we don’t need is the current poseur stumbling about who can’t even remember what was going on a little over a month ago.
