Are all the controll rods pulled when the nuclear power plant run at maximum?

I am assuming you are asking if all rods are fully withdrawn - the answer is no.  Since the fuel (e.g., uranium) is gradually spent when it undergoes fission, you have to put more uranium than you initially need into the reactor core.  Otherwise, you would have to keep adding fuel (this would be expensive) in order to keep operating at the "max" power.  Since it is slow and painful to change out the fuel, the fuel cells contain more fuel than they need, and so the plant operates with the control rods only partially withdrawn.  As the plant ages and the fuel is being used up, the height at which the rods are maintained increases, until the end of the reactor core life, when the rods being fully withdrawn will not supply enough power.  This is simplified explanation; there are a lot of other factors which affect rod height also (temperature, recent power history, etc.).  I have ignored those for simplicity - it is still an accurate explanation.\n\nIf you are asking if some control rods remain at the bottom of the core when operating, I've never seen this.  I have, however, seen reactors where SOME rods are fully withdrawn, while the remaining ones are only partially withdrawn.

CanTexan is on the right path. More specifically, Nuclear Reactors create Heat. This heat energy creates a Pressure in the transfer medium (Water -> Steam) and is transferred to Rotational Mechanical Energy in a turbine. The attached Generator produces Electrical Energy.

an power plant will consume more input than it will produce in output.  even fusion power plants will not be 100% efficient due to transmission loss and transfer loss.

Nuclear power is very raw and easy to create.  Very little has to be done to provide immense amounts of power.  Infact, if more than necessary is done (say you move a certain part more than an inch), too much power can be produced, causing a nuclear meltdown.  \n\nI'm not the nuclear expert, so I won't go into specifics.  I fully believe that we will only run out of nuclear power if the Earth were to be no more.

Maybe the one on this page will suffice,\nhttp://science.howstuffworks.com/nuclear-power3.htm\nAnd its animated, thats a bonus, but it isnt really a flow chart.

well depending on how well it's built, the same thing that would happen to any reactor hear in the US if it core was breached. You would have a radiation leak

Nations such as France and Japan use nuclear power to generate massive amounts of electricity.  That means they're using less oil, coal and natural gas.

This all comes down to human performance.  The cast of likely culprits would be in the 100's.  Ultimately, if you want to be  a hard nose about it, it was the fault of the shift reactor operator at the time that it happened.  That would only be because his license was the "One" that was allowing the plant to be operated at that moment.  The utility is responsible along with the operator for all consequences of operating the plant.

Reactor : To generate heat. Thats where the radioactive stuff is.\n\nModerating Rods : to control the rate of heat release from the reactor.\n\nBoiler : To generate steam and to cool down the reactor. (Moderating rods are used assuming what is called a heat load on the boiler ie that its full of water and making steam. What happened at Three Mile Island was that they thought there was water in the boiler and there wasn't)\n\nTurbine : to make electricity from the steam\n\nCondenser : to turn the steam back to water (If the turbine is not a condensing turbine)\n\nPump : to pump the condensed water back into the boiler\n\nInstrumentation : measuring flows, pressures, temperatures, liquid levels etc, and lots and lots of it to let you know whats happening and keep the thing safe. (what happened at Chernoble is that the emergency instrumentation was "overridden" which means its didn't shut the plant down when it should have)\n\nConcrete : to keep everything isolated.\n\nA very simple overview, hope it was interesting.

All the above is true,\nIt also however formed the basic understanding of Nuclear power generation.  The reaction that causes an explosion for a weapon, is the same as that in a reactor except it is controlled.  Modern ( western) nuclear generators can trace their lineage back to the Manhatten Project.

Do you mean what happens in a power plant with a 1000 MW capacity when the demand is only 750 MW?  The answer to that is that he plant only puts out 750 MW.  In a case like that, whatever is providing the energy for the plant (say a turbine engine) will not have to push as hard, and will use less fuel, than when the full capacity is needed.  As an experiment, you can connect a bulb, through a switch, to a little hand-cranked generator.  When the switch is off, it's real easy to turn the crank; but when the switch is turned on, you suddenly have to crank much harder to keep the light lit.

ALOT just see for yourself.\n\n(It's a chart)\n\nhttp://www.nrdc.org/nuclear/nudb/datab9.asp

In Japan a few years ago the workers at one facility were carrying radioactive solutions in buckets from one place to another where they put so much of it that it started having nuclear reactions from reaching a critical amount.  This was amazing news, but it happens that the people doing mundane, dirty, or high exposure work often know little and are only following or misfollowing instructions of more knowledgeable scientists who are not always there to prevent mistakes.\n\nAlso, one time in the USA, out west, a man was working on a reactor and, they say, everyone had been told not to remove a certain vital control rod.  But he did, and instantly the reactor exploded, releasing radioactive contaminants inside the containment.  The mans body was found on the ceiling impaled by the control rod.\n\nThat sounds like a made up story, I know, but I have heard it told about three times from VERY reputable and different sources.\n\nAnother time was during the testing of fissionable materials in the laboratory at Los Alamos where the first atom bombs were developed.\n\nOne scientist was investigating critical mass by bringing two hemispheres or pieces of fissionable materials slowly closer to each other on some kind of track.  He got them too close and did not get them apart fast enough.  The radiation exposure was so intense he died shortly after that, also I believe one other person who was in the room.

Torent reactor is good

Not in your kitchen, but at the power station - yes (unless it is nuclear or wind powered)
