Q,

Nuclear plants are best suited for base (full) load operations. Their ability to load follow is slow and usually causes more problems for plant operations than it is worth. Also, power distribution and hence nuclear fuel burnup is optimum at max unit power.

regards
homer

quehubo, Do most cc runs on natural gas? My experience with coal-fired plants is that they can ramp maybe 10% over an hour's time in terms of energy output.

So some ramping but clearly not the instantaneous ramping of a hydropower project or very quick response of a combined cycle generator.

Question for you Quehubo. Do all CC's require cooling water -or do some CC's run strictly on an air-cooled basis. Needless to say if water requirements are high on these replacement NG-Burning CC plants -especially out West- then replacing hydro with NG weirdly may solve one surface water problem, but then create another groundwater usage problem with having to cool the new plants....

Also a lot of my friends from the Carter work for environmental groups now. I communicate with them frequently and we discuss ways to retire coal-fired plants in a way so as not to impact the total energy supply avaialble and the incredible life-style changing things going on in Silicon Valley in California or Route 128(?) in Boston, Austin, Texas or Telcom Corridor in Dallas, etc.

That is Key Economic Issue No. 1 for all Americans I believe in the power/oil & gas arena- keep the energy supplies feeding this unbelievable technological explosion- I only wish I were a younger man or woman and could be around when the days of routine commercial space travel arrive- less than 100 years away now I believe.....Maybe be the first ever space pirates, ha! Drinking rum in weightlessness! Yo ho! Yo ho! A pirate's life for me, ha! (Even though it's technically politically incorrect, I kinda like the way Walt Disney depicts a pirates' life at the "Pirates of the Caribbean" Ride at Disney Land, Sign me up for a tour of duty ha!

This again may be another source of NG usage long-term (fuel cells)....

y amigo que significa el apodo de "Quehubo"??
