That would be a helluva resistor!  Cooling would require the equal of say, another cooling tower, or cooling pond, more circ pumps, and BIG pipes and make up water.  All used very infrequently, costing $$$.  All requiring periodic testing.

"Transmission faults" take time to identify, troubleshoot and restore. And you STILL have to be ready for an internal generator or step-up transformer fault anyway.  When THAT happens, the Main Steam Stop Valves (actuality ALL steam turbine valves) slam shut, and the resistor would be unused. 

Large step/rapid changes in Rx power are difficult to control due to Xenon poisoning.   See:  https://en.wikipedia.org/wiki/Xenon-135  

That's one reason nuc plants don't "participate" in dispatch.  They run pedal-to-the-metal (except for periodic minor derates due to required on-line turbine valve testing and the like).

There are main steam bypass valves directly to the condenser on BWR's (not sure about PWR's),  but only designed for part-flow (say 20%?) used during starting, and taking a real wear and tear toll on the condenser as well.

Again, If the issue at South Texas #1 was the loss of a reactor feed pump (on the primary side), why that pump was not being supplied by the aux transformer.

I find most news reports about plant outages inaccurate, anyway.

Thanks that may explain the reason why it isn't done.

If you shut the steam off to a 1000MW / 500MW turbine how long does it take to decelerate down to zero?

Typically coast-downs are about 45 minutes (or longer or shorter). It really depends on the condenser vacuum level.  If the operator "breaks" vacuum (opens a valve to atmosphere), it WILL be shorter.  If a good vacuum is maintained (shaft steam seals still operable because steam is still available from "somewhere", circ water pumps still operable), it could be longer.

Just keep that lube oil flowing, even low speed on turning/jacking gear, else heat flux from the hot rotors will melt the babbitt/white metal bearings.

Thats one paper written by a researcher. 

In any case if you read the text the predicted cooling will be  swamped by AGW driven rises. 

In effect it  will moderate temperature rises over the next 30 years rather than actually cool the earth. The other side of that situation is what happens after the earth comes out of the grand solar minimum? 

No Nick, not just one paper, but an entire school of scientists in Finland and Russia and Britain and U.S. who have published voluminous work in recent decades. And no again, there will be a cooling, just read the text.

We can now wait and see which climate model is valid, the global warming model or the global cooling model, that is how science works.

The key research question here is

A: Did Al Gore actual state that?

B: Did Ron put that on a picture / pick up the picture from the internet?

You obsessed with conspiracy theories? Poor old Al Gore was never a scientist, just a political guy.

He just signed on to the wrong climate model.

Nick, your material is out of date, new models are on the scene.

Here is one, showing a cooling phase of several decades starting now. This is currently the best explanatory model with a 94% success rate, far above the outdated models which the Biden folks are relying on.

Pot, kettle, black

Its you lot obsessed that AGW is some globalist / elitist / plot to impoverish you through taxes. 

I just think its unsporting to label people in such a way of they never said that. 

If Gore did say no snow by 2013 lets see the evidence please.

Al Gore was a generous supplier of hyperbolic overstatement, the likes of which I have never seen.  For him, the climate was an emergency alarm, going off every time he took the podium to screech out his message. You already know that, Nick.

Interesting that 1998 was near the solar minimum. For years denialists have been telling me that 1998 was the hottest year ever and it had been cooling ever since / its all solar related . 

1998 was an abnormally hot year (not the hottest on record) so clearly the 11 year solar cycle has little influence on global temperature .

I believe 2016 and 2020 are the hottest years on record  which are the peak and trough respectively.

Looks like the grid may have forced South Texas Unit #1 off.  Hard to tell from this report.  You would think that a reactor feedpump would be supplied by the housepower (auxiliary) transformer.

This was the outcome of the civil legal case in the UK (Civil cases have a lower burden of proof for the plantiff who was challenging the showing of AG's film in schools) 

The Legal Case

The film is also subject to attack on the grounds that Al Gore was prosecuted in the UK and a judge found many errors in the film. This is untrue.

The case, heard in the civil court, was brought by a school governor against the Secretary of State for Education, in an attempt to prevent the film being distributed to schools. Mr. Justice Burton, in his judgement, ordered that teaching notes accompanying the film should be modified to clarify the speculative (and occasionally hyperbolic) presentation of some issues.

Mr. Justice Burton found no errors at all in the science. In his written judgement, the word error appears in quotes each time it is used – nine points formed the entirety of his judgement - indicating that he did not support the assertion the points were erroneous. About the film in general, he said this:

17. I turn to AIT, the film. The following is clear:

i) It is substantially founded upon scientific research and fact, albeit that the science is used, in the hands of a talented politician and communicator, to make a political statement and to support a political programme.

22. I have no doubt that Dr Stott, the Defendant's expert, is right when he says that:
"Al Gore's presentation of the causes and likely effects of climate change in the film was broadly accurate."

The judge did identify statements that had political implications he felt needed qualification in the guidance notes for teachers, and ordered that both qualifications on the science and the political implications should be included in the notes. Al Gore was not involved in the case, was not prosecuted, and because the trial was not a criminal case, there was no jury, and no guilty verdict was handed down.

See above

His film was examined in a court of law in the UK in a civil case trying to prevent it being shown in schools

A lot of expert opinion was sort and the conclusion was it was broadly accurate 

Case thrown out.

The paper you cite predicts a cooling effect by the speculated GSM of upto 1 degree C by 2070

To be fair that may moderate global warming and buy some time but it won't lead to an absolute cooling - the thermometer will still be rising albeit a little more slowly. 

The downside of this is what happens when it comes out of that minimum? Ok not an issue for me but may well be for my children and grandchildren.
