James Hansen takes stage at COP21 to explain carbon fee and dividend

ByRod Adams

…nd generate until things can recover are nukes. And no nukes can survive a load rejection anymore, with a rapid runback to low load limit supplying their own power required to stay operating until the grid can be recovered. Post-TMI2 NRC required changes eliminated the runback capability. Doomsday scenario? Not hardly, a single grid interconnect fault in Arizona took down most of the generators in S Cal. A hardened selective portion of the nationa…

With immediate and profound changes, U.S. nuclear power can become an unexpected but welcome low carbon wedge

ByRod Adams

…his they may have to start up peaking turbines or use the “smart Meters or Load Shedding Switches to reduce the grid load to prevent brownouts or even blackouts on loss of the RE when the wind stops blowing. [Think of the incident in South Australia last year.] Because of that fact the customers, ME and the other paying the bill, are paying for that Faux Cheap RE and the operating power plant that is not making any power. We are paying for the sma…

Naval Reactors should be empowered to show the way – again

ByRod Adams

…of peak demand (especially from heating loads in winter), and lots of baseload. “France mostly exports baseload electricity, while its imports mainly occur during peak periods” (p. 109). If you can figure out how to sell electricity at periods of low demand above those of peak periods, please let us know. That would be some serious proprietary stuff indeed, and perhaps of great benefit to consumers and energy developers worldwide. A revolution, p…

Update: One-Woman Crusade to Encourage Exelon to Restore the Zion Nuclear Power Plant and Operate it In Her Backyard

…cerns are not an issue, nuclear can meet much of our energy need including load following, and that manufacturing processes can be scaled elsewhere without the available local technical or manufacturing capacity). These are real constraints. In fact, I would argue that nuclear needs renewables and other low carbon sources of energy (the sun shines brightest during times of peak demand) at least as much as renewables need back up power from natural…

Mark Jacobson condenses 26 years of wind, water, solar research to 6.5 minute barrage

…ea for wind turbines, however they are getting a 16% CF ignoring the house loads. Thus even the best sites will only give you a Net CF in the range of 20% or so. Think 5% House Loads is to big? Well if these 42 sites have a total of 400 wind turbines then that means they are only consuming 597 KWhr each on average. That is less than six 100 watt light bulbs. As I have posted further up this Blog. The real house loads are in the neighborhood of 15%…

Focus on food, water, shelter. Dr. Greg Jaczko is wrong and giving dangerously bad advice

ByRod Adams

…l since at 6-7 days into a loss of power boiling is likely with a full off load of fresh fuel. But since the fuel was off loaded in November it has had 4 months of decay which should reduce the load markedly. I would estimate (a wild guess) that there is about 8 million Btu/hr in the pool. At this rate and a full cavity and dryer separtor pit boiling might occur in 10 days or so. Regardless vapor should be seen. Without vapor from the pool the bes…

Holding State Lands Commission accountable

…et of PWRs humming away at 100% power, with an overlay of BWRs that can do load-following on top of the baseload capacity. Nuclear could do it all. Throw in some fast-spectrum reactors that have a dual purpose of actinide burning and power production, and you’d come close to closing the back end of the fuel cycle. Sure, it might take three or four generations of SFRs to burn down the actinide inventory, but in the meantime those SFRs would be trem…

Northwest wind takes a week-long vacation

ByRod Adams

…jd Something about the graphs I don’t understand. Is the red line labeled “load” just the load on the BPA distribution system alone? Easiest to see at left side, but the total generation exceeds the load by about 3500 MW. Are they pumping up storage, selling outside of their system, etc? That’s quite an excess of generation over what they call “load.” Pete51 This link is a bit easier to see all of France’s power generation. http://www.rte-france.c…

Nuclear plants performed well during Sandy – as expected by professionals

ByRod Adams

…the reports are silent? William Vaughn @Rob I note that the wiki page on “Load following power plants” points out that the French PWRs use something called “grey” control rods to adjust their power output. Is there some licensing restriction that prevents US plants using the same technology or is there some technical reason why older plants like Oyster Creek can’t be upgraded? I find it a curious engineering mindset that these plants weren’t orig…

Assembling reliable off grid power system for emergency preparedness

ByRod Adams

…is high capacity, reliable, dispatchable, has some measure of flexibility (load following), and uses proven technology. The alternative of using an inherently non-dispatchable primary energy source (wind and solar), then going through the hassle of converting it to a marginally dispatchable system by implementing various storage schemes, along with their costs and inefficiencies (energy losses), seems less desirable. Has anyone built a utility-sca…
