8.9

Winky, I fail to see why the power generating plant is on the grid in the first place. It is the power generating plant. There is no need for SCRAM if the power to the cooling system is still in effect. The cooling system can stay in effect with the power generated by the power generation of the plant it's sitting in.
 
The plants have been on the (external) grid for a few days now. The problems are more than that at this point, salt water isn't kind to mechanical or electrical equipment.

My newest camera that we ordered last week was delivered today, a well timed purchase. Sony shut 8 plants including the one that produces the imaging units for their video cameras, a clean-room operation effected by the quake. They had shipping containers on the docks and the supply chain is always tight.

Between a combo of sale, rebate and a professional promo I saved about a grand on the purchase. From what I read the price has already jumped by $300 and is expected to rise further.
 
evidently not

why can't it still use the input, and just disconnect the output?

Do you have the vaguest clue how the steam turbine
and the generator work?

=========================================================
Loss of only one ten-millionth part (10−7) of the beam is sufficient to quench a superconducting magnet, while the beam dump must absorb 362 MJ (87 kilograms of TNT) for each of the two beams. These energies are carried by very little matter: under nominal operating conditions (2,808 bunches per beam, 1.15×1011 protons per bunch), the beam pipes contain 1.0×10−9 gram of hydrogen, which, in standard conditions for temperature and pressure, would fill the volume of one grain of fine sand.

Your abject ignorance on the subject
has no bearing on my superior knowledge?
 
Since you can't answer the question, it appears we have ignorance all around.
 
No I have thought about this
I am fully capable of accurately
answering this question.

The issue is your ignorance in many different areas.

If I was talking to you face to face or even on the phone
I could explain fission,
(and how a nuclear excursion takes place in milli-seconds)
prompt critical, delayed neutrons, nuclear poisons
how you can't just throttle up and down the thermal output
of a reactor like it was a lawn mower

The idea that a steam turbine can over speed if unloaded
and that the 25,000 volts @ 25,000 amps output of the generator
has to be connected to a load (the grid) and what type of outrageously
expensive equipment would be required onsite to sink this massive load
if you were going to try to run the plant off the grid
a giant investment in a piece of equipment that you'd never use in the first place

and I could go on and on as to why you must not understand enough
regarding this issue or you would never have posed such a question in the first place.

Today there is a fire in building four in the fuel storage pool.

This is a nuclear accident of mammoth proportions and it proves
beyond any doubt that nuclear power is insanely safe.
Very little radiation will be released and no one is going to be killed
The tsunami has killed thousands

But ignorant people are already clamoring to have plants shut down
and this saddens me... :(

So Gonz what was the question again?

Why couldn't they just keep the plant running even after
a 30 foot tall wall of water washed over the plant?

Gee I haven't a freakin' clue
 
winky, I think where the misunderstanding is, is what energy usage is needed,
and to do what in the plant.

I do have a pretty full knowledge of both turbines, and generators.

I don't think being condescending is advancing the conversation.
Can't we be patient here.?
 
It's not a good thing

no you can not be a patient here
Obamacare doesn't take affect until 2014

Why couldn't these plants get hit with a 8.9 earthquake
and have a tsunami wash over them and remain in operation?
 
I understand why they could not remain 'in operation', at least for a time,
because or safety.
I'm guessing the workers had lights to use while it was down though.

Were the lights on generator, or the grid?
 
workers? I dunno
people? all I know is about about 250k are in shelters

I know several workers were there though,
because they evacuated yesterday, and some went back today.

I hear some 'experts' saying the main problem was the water pumps.
I can understand about that, because it takes much more power to
turn a water pump with electricity than diesel, as I said.

I wonder if they are using electricity to pump the water while in active operation.
Seems something amiss with this whole situation in the design.
 
All the electricity that the plant generates has to go somewhere - the grid. The grid is the only thing large enough to handle all that output.

The plant itself cannot possibly consume all of the energy it creates... electricity has a way of making things hot..particularly wires and the motors they are attached to.

SO If the grid is down, all that power output has to stop...so the plant begins to shut down it's output. It has to stop the reaction. It needs coolant.

It needs power to run the pumps of coolant.

The grid is down, so that's out. It can't feed itself..that's too much energy. So it uses diesel generators.

Or rather, it would use generators, if those hadn't been damaged by the earthquake, the tsunami the heat from the fires, the nuclear cores exposure.

You get the idea.

The problem is that it has TOO MUCH POWER, can't get rid of it fast enough and can't cool off all the heat that power is generating.

Nasty cycle, that.

Any questions?
