The EPA Carbon Plan: Coal Loses, But Who Wins?
Lasrick writes: Mark Cooper with one of the best explanations of some of the most pressing details on the new EPA rule change: 'The claims and counterclaims about EPA's proposed carbon pollution standards have filled the air: It will boost nuclear. It will expand renewables. It promotes energy efficiency. It will kill coal. It changes everything. It accomplishes almost nothing.' Cooper notes that although it's clear that coal is the big loser in the rule change, the rule itself doesn't really pick winners in terms of offering sweet deals for any particular technology; however, it seems that nuclear is also a loser in this formulation, because 'Assuming that states generally adhere to the prime directive of public utility resource acquisition—choosing the lowest-cost approach—the proposed rule will not alter the dismal prospects of nuclear power...' Nuclear power does seem to be struggling with economic burdens and a reluctance from taxpayers to pay continuing subsides in areas such as storage and cleanup. It seems that nuclear is another loser in the new EPA rule change.
I think you can be sure no matter how this plays out, power is going to be more expensive. In addition, if the coal-fired plants are removed from the equation before replacement sources of power are in place, there will be power shortages.
We freeze in the dark.
Oliver's law of assumed responsibility: If you're seen fixing it, you will be blamed for breaking it.
Of course nuclear power doesn't seem viable if you look at it's current state! All the reactors we have now were designed in the '50s. They use water as a moderator (ie thermal neutrons) and coolant, requiring complex assemblies of fuel rods and control rods. Thermal neutrons also cause way more incidental nuclear waste (irradiated steel cores, wires, etc). They use
It doesn't have to be that way! The most recent design for a fast reactor seems to be the most legitimate and feasible new design to date. It's called the dual fluid reactor. http://dual-fluid-reactor.org/
It separates the fuel loop from the coolant loop. This has numerous advantages. You can alter the rate of either independently to best suit the current need. The coolant used isn't liquid sodium. Which, aside from not playing nice with air and water has a low boiling point and high neutron cross section. This reactor uses liquid lead as its coolant. Its so stable and resistant to radiation that the coolant loop can be piped into the non-containment area for power generation. In the papers I've read they mention coupling it to an MHR generator then a super-critical water loop en route to turbines.
It is engineered to run at 1000C, which at that temperature, makes it possible to do pyro-chemistry with electrodes to filter out the daught products in line with the fuel loop. The separated daughter products are then sent to a passive cooling chamber (the super short lived ones are hooked up to the coolant loop where it contributes to energy production) where they remain hella hot for a few hundred years. Then they become inert. There are supposedly lots of valuble metals after about 90 years that make the waste itself a hot commodity.
The reactor is designed to be a 2 meter cube, for simple production there are no bowed parts, only 90 angles with straight pipes. A reactor this size can put out 1500MW thermal.
Couple this with the recent advancement of laser-based particle accelerators and you wouldn't even have to start with enriched fuel! The power required to drive the laser would be
As Elon Musk would say (probably): Seriously guys, it's the 21st century, act like it!
Because of our dear President's own stance, we will not be opening new nuclear plants until he's gone.
Perhaps you can explain why the two new units at the Vogtle Plant in Georgia were allowed to go through then and even offered federal loan guarantees.
(From the article): On February 16, 2010, President Obama announced $8.33 billion in federal loan guarantees toward the construction cost,
Would Obama have done that if he was against nuclear power like you believe?
Nuclear is the cheapest per megawatt power source we currently have.
What have you been smoking? The main reason so few nuclear plants have been built in the US since the 1970's was that it was far more expensive than building a coal plant. Now planned coal plants have been cancelled because they weren't expected to be able to compete with solar when they were finished.
I agree with you that we should reprocess the spent fuel rods.
Solyndra was just a talking point for the Republicans to pound the President on. The program that the Solyndra loan was a part of was budgeted for a 10 or 11% loss rate and even with Solyndra it still had less than 5% losses. Solyndra lost out because of the unexpected drop in prices of solar modules from China that it couldn't compete with. It's unreasonable to expect that everything that gets tried like this will work out.
Yes. Because STORAGE was the problem at Fukushima.
Sorry son. Shitty MANAGEMENT and lazy engineering practice, plus a metric fuckton of "Mother Nature Always Wins"
The plant actually SURVIVED a magnitude 9.0 earthquake.
The reason it finally overheated was because the asshats at TEPCO ignored the calls of real engineers for a MUCH higher sea wall. So the tsunami set off by the TÅhoku quake may as well have had valet parking at the reactor when it hit land.
Right now we have the ability to build reactors that are PASSIVELY safe. It means you don't have to worry about failures in ACTIVE, mechanical cooling systems. When such a reactor is shut down, it dumps its fuel into a dump tank and the entire reactor simply cools off. No need to worry if the generators will kick in. No need to worry if the facility loses power. Natural, powered by a little thing we call GRAVITY. It's about as idiot proof as you're going to get until we figure out how to spot-reverse gravity.
And yes, there's always going to be SOME waste.
The stuff that they're pulling out of reactors today? Mildly radioactive. And will be for hundreds or thousands of years.
The stuff you would pull out of a liquid fuel reactor?
1: Medically useful.
2: Shitty bomb-making material.
3: Scientifically useful (and an element we actually can't get any more of).
4: HIGHLY radioactive. But INCREDIBLY short-lived. Some of it is gone within hours of extraction. The longest lived stuff will be a few years cooking off. As opposed to MILLENNIA with current solid-fuel reactors.
Ideal application for reactors such as these is to take them and bury them in concrete. Let them run their usable lifetime and then decommission them. Once it hits EOL, you drain the device and cap it. Then give it a decade or two to cool off (radiologically speaking).
Maybe we CANNOT guarantee that we can build a facility that'll last thousands of years, through god-knows-what. But storage bunkers intended for product with a 10-50 year shelf-life? Pfft.

Half a century (plus) and counting.
And remember, these things can be fairly compact and relatively light (they were initially designed as a power system for a plane). These things could replace diesel generators and even small hydro installations. WORLDWIDE.
Yes. Dropping one into the San Andreas Fault, or Yellowstone National Park, or the New Madrid Fault would probably be a FUCKING DUMB IDEA.
So here's a smarter one. We don't DO that. We drop them in more geologically stable areas instead.

THANK GOD!!!
The government has been running different programs like that for a long time (more than 50 years) to help encourage new technologies to get off the ground. They always write in a 10 or 15% loss rate into them and the programs seldom reach that rate. In fact the boost to the economy for the ones that do succeed probably far outweigh any losses in the programs.
The coal plants can still be "plugged in" and operated during times of peak load (weekday summer afternoons and winter mornings); what they can't do is operate much the rest of the time.
The problem with this is that coal plants can't operate this way. A typical coal plant takes 4-8 hours to reach full power from a warm start and can take 24 hours to cold start. This is why we currently use them for baseload power and use other sources (mostly natural gas and hydro) for load following.
