Should Nuclear and Renewable Energy Supporters Stop Fighting?

Lasrick writes "A debate is happening in the pages of the Bulletin of the Atomic Scientists that started with their publication of 'Nuclear vs. Renewables: Divided They Fall,' an article by Dawn Stover that chides nuclear energy advocates and advocates of renewable energy for bickering over the deck chairs while climate change sinks the ship, and while the fossil fuel industry reaps the rewards of the clean energy camp's refusal to work together. Many of the clean energy folks took umbrage at the description of nuclear power as 'clean energy,' so the Civil Society Institute has responded with a detailed look at exactly why they believe nuclear power will not be needed as the world transitions to clean energy."

      In the UK, however, there seems to be only one plant (http://en.wikipedia.org/wiki/Dinorwig_Power_Station), costing 425M GBP in 1974 capable of absorbing around 1GW worth of power, so nowhere near 50% of base load, so it seems that PSH costs around 425M/1G = 0.5 pounds per watt capacity. Apparently, a new nuclear plant costs about US$ 5,339/kW., or 4 pounds per watt capacity, while windmills cost around 1-2 pounds per watt. So, assuming enough sites for PSH can be found, the costs for power storage capacity seems to be 5-25% of the cost for generation capacity.

      According to the wiki, "The stalling of the UK nuclear power programme in the late 1980s and the coincident "dash for gas" increased the network's ability to respond to changes in demand, making the use of pumped storage for day/night load balancing less attractive. As a result, a similar facility planned for Exmoor was never built.[2]"; so it seems that at the time the demand is what limited PSH construction, not cost or environmental factors.

There is a problem known as Neutron poisoning where the byproducts of fission build up in a reactor's core and absorb more and more neutrons. Some of these neutron absorbers are "burned off" when a reactor is in operation, by absorbing neutrons and then decaying into other things. Problem is, the neutron poisons are produced by radioactive decay that has non zero half lives. This means that they will show up in your reactor some time after you shut it down. This makes throttling the reactor difficult because you have to account for the eventual production of neutron poisons when turning the power down. If you don't, and you don't have any neutron absorbing control rods to remove to keep the reaction going, the reactor will shut itself down. This is more and more of a concern as you get late in your fuel cycle.

These designs are very safe but still bring along with them the baggage of the problems of designs have been derived from ancient research and plutonium producing reactors. They still use solid fuel rod designs optimized for producing mushroom clouds over battlefields than producing electricity. The coolant is water, something more suited for coal than a power source capable of reaching temperatures that can disassociate the water into hydrogen and oxygen gasses. The boilers are large vats filled with water, graphite control rods, and zirconium clad fuel rods. Should the reactor get too hot the water will boil. The steam from that will react with the graphite and zirconium, setting them on fire. This will mean the creation of highly flammable gasses like O2, H2, and CO. The molten fuel will collect on the bottom of the reactor, getting hotter and hotter as the moderator burns off or boils away.

      The insurance companies will insure against this melt down condition because the physics behind all of this is well known, and because the designers have assured everyone involved on the near impossibility of this happening. They will show that such a catastrophic meltdown cannot happen because there are multiple redundant cooling systems, each capable of quenching any fire and nuclear fission that may result.

      They will get their funding and license to operate because this is a known design with known risks. At the same time they will refuse the construction of a generation IV reactor design, a molten salt reactor. The insurance people and the government license board will ask to see their passive water cooling supply, and then be shocked that there is no cooling water supply. The temperature a MSR operates within would turn water into a fireball. Instead a supply of neutron absorbing salt is shown as a means for emergency cooling. They ask to see the containment dome drawings. No such drawings exist as no water means no radioactive steam. A meltdown condition is dealt with by allowing the non-radioactive elements to boil off and escape, leaving the heavier radioactive elements to collect at the bottom of the structure.

      So, we get inferior nuclear reactors licensed and insured. We have safer nuclear reactors on the drawing board with all kinds of simulations, equations, and stacks upon stacks of documentation showing how much cheaper, safer, and more profitable they are to operate. They don't get licensed because it is so different than what they've seen before that they don't even know how to issue a license.

You have a collection of meal bars in said compartment to last you 20 years, and they are individually vacuum sealed well enough to stay preserved for 100 years, meaning that there is no significant amount of decomposition going on with them. The sources I can find suggest that typical human biological processes would result in having about 10 days worth of air, assuming it's at normal composition, and that your body can still function until there is no oxygen left in the room.

    1. Cheap storage. Something like flywheels or ultra capacitors. Batteries are a non starter.

    2. Decentralized generation. Ideally on top of your actual house. A percentage of power is lost in transmission over long distances. A percentage of power is lost meeting demand largely by over supplying a bit... there are other things that each shave their percentage off the total. Add them all up and its a significant amount of power. If the power were provided locally you'd get most of that back.

    3. Extremely cheap solar panels. We need something so cheap that you can put it on every surface without thinking about the cost. The efficiency doesn't have to be great. It just needs to be insanely cheap. Do that, and then link everything up to that... and then maybe you'll need a few high efficiency cells.

    Get everyone running mostly on their own generation and they'll start conserving power. Not because they want to conserve but because they would run out of power otherwise.

    Ideally do the same thing with water as well... at least in so far as having a cistern that is fed from municipal supply. So if there is a disruption or there are months when the water is expensive... they can shift around. Also, in California they're talking about water rationing again.

The teachnological one is developing a functioning technology. There are hurdles to overcome but there is reason to believe they could be overcome. After all, fuel cells and the like are already in existence and prototype vehicles have been made. The much bigger problem is economic. The first economic problem is that hydrogen powered cars are expensive because there is no manufacturing economies of scale, supporting industries and a limited manufacturing base. Absent some sort of subsidy they cannot be produced for a price in the near term that is competitive with existing vehicles. The second economic problem and the real killer is that there is no fuel infrastructure in place and developing one would be hugely expensive. We have infrastructure in place for natural gas, petroleum/diesel products and electricity. Anything that doesn't use one of those three things is essentially starting from scratch.

    The truth is that if you want every person to own an electric car, Hydrogen is the only way you get there.

Electric vehicles based on batteries become practical once you solve the charging time problem. Basically you have to get charging time down below about 10 minutes for at least 200 miles of range.

France has an artificial high base load, about 60% - 65% , because it cant steer its nuclear plants good enough, so they have to rely on neighbours to buy their excess power or on heavy industrial processes at night (oh, what comes to mind, wow: nuclear fuel reprocessing).

      Base load is the amount of load you always feed into the grid regardless of demand. Base load plants run at more or less constant output. So: how the funk (see, I calmed down) should a french base load plant react on a german power surge? Easy answer: it can't.
      Complex answer: it can be planned. When I run a french nuke, I know I produce excess power between 1:00 and 5:00 at night. (Unfortunately at that time germany does not buy french excess base load power) If I run 30 of such plants, I know I have excess power from 21:00 till 8:00 (at a varying degree). I might put that on the market. Or I might run a complex schema of powering down plants 1-10 while running 11-30 on a fixed output. But the 10 I have powered down will have trouble to get up again ... they need a few days to get rid of neutron poisoning. So my complex schema now requires me on the next day to _try_ to power up 1-10 while I power down 21-30 and keep 11-20 running on full power (well, they where on 85% only anyway), or I might increase 21-30 to 95% ... and with shifting around the plants I power down each day and up the other day and the gaps of surplus and lack of power get filled by neighbours.

      Wow, suddenly when we look at the discussion from France perspective we figure: stupid idea to have 75% - 80% of your power production relying on nuclear. As you are forced to have a neighbour who can as well BUY your surplus power as FEED you with the badly needed power in case your plants are to slow.

      Actually, that above was exaggerating: France buys our power mainly to refill its pumped storages (which it needs to balance the grid. You need about 7% total power production to balance the grid with either pumped storage or gas turbines ... and the equivalent of about 10 days power production as total storage, if you rely mainly on pumped storage)

Transformers provide an efficient and economical way to convert between different voltages, something the DC systems of the time did not have. Voltage conversion is a vital part of any large scale electricity grid as the voltages that are appropriate for generation and use are very different from the voltages that are appropriate for transmission and distribution. DC can also be problematic for end use because it's far more prone to sustaining arcs than AC is.

      Consider this your correction. With modern technologies, High Voltage DC is actually the preferred method for long-distance power transmission. In the past, the issue was always the AC/DC conversion at either end of the line.

      HVDC has a number of things to recommend it.

      1) Uses the entirety of the conductor for power transmission. When you push AC through a conductor, it exhibits what's called the "Skin Effect." In the case of 60Hz AC, the power is actually only using about the outer 7mm of the conductor. Power companies actually do make use of this, using a steel core for tensile strength, and a copper sheath for high conductivity, but it also puts a limit on how much current a given conductor can actually carry. At DC, the power will flow through the entirety of the conductor, and since resistance is proportional to the cross-section area of the conductor, you get less loss for a given piece of cable.
      2) AC loses significant amounts of power to the ground through capacitive losses. In effect, the transmission line forms a very large capacitor with the earth. For long transmission lines this becomes a significant effect. Again, because this is due to frequency, DC solves the problem.
      3) Isolates and relaxes the frequency requirements of the grid. After they lost most of the power grid to an ice storm in 1998, Quebec Hydro rebuilt their grid using HVDC transmission lines and interconnects to the eastern grid. Because of this, they were isolated from the frequency instability that caused the large north-east blackout in 2003 and thus the lights stayed on.

      Anyhow, the main reason why AC has been used for long haul transmission is because when the grid was built out, there was no efficient way to convert power between AC and DC or to change the voltage once it was in the DC domain. With the advent of modern power electronics, it's quite possible to build megawatt and/or gigawatt scale inverter/rectifiers that will do this more efficiently than the AC losses for long distance power transmission. As with all of our crumbling infrastructure, the main problem is that no one is willing to invest in the capital expenditures to make it happen.

      Thanks for the data, your information is interesting. You do make me feel a little bad for hitting you with this, but I'm scared shitless from climate change.

      6 pointer earthquakes are a non issue for nukes. It's the 7.5+ pointer ones that actually are trouble. Specially the 8.0 plus (the strongest ones you see in the Ring of Fire). You know that from a 6 to an 8 pointer there's 100 times increase in energy ?

      Nukes secondary containment structures have extremely solid steel+concrete structures (as strong as one meter of solid steel), and they are only needed in case of a meltdown/rupture of internal core plumbing, so only extreme tornadoes are any risk, and even then a small one (except for Chernobyl style nukes, which there are none in any serious democracies, developed or not, Chernobyl didn't have that, I believe that even former USSR states got rid of all of them after Chernobyl).

      Water cooled nuclear isn't load following, but fluid fuel nukes are (Thorium LFTR and IFR). Germany could take that extra energy and pump water back into dams, produce hydrogen (fuel cell cars are starting mass production in 2014, although I like Elon Musk's statement that they are fool cells, except when you have enormous electricity surplus you could use to produce hydrogen from them, producing hydrogen from natural gas is an environmental stupidity).

      Specially interesting is Thorium LFTR technology, because they can operate at 700C (with possibility of higher temp designs), which is hot enough to run many industrial processes that otherwise would burn natural gas (or petrol/coal if natural gas is unavailable). For instance, an Oil refinery typically burns natural gas to produce process heat for refining fuels. That gas could otherwise be used to power cars or heat homes. Canada tar sands production is looking into high temperature nuclear to power their filthy oil extraction from tar sands processes (so they can export their gas to Japan). Process heat is also needed to produce fertilizers, run petrochemical processes (like producing plastic/nylon/...). This could also be used to directly produce renewable fuels from H2O + CO2 (directly replacing gasoline and diesel). I'm yet to see a case of high temperature process heat from solar directly (doing this from electricity would be extremely inefficient).

      One smart thing the Germans could do is a 160Km/h speed limit (trying to propose something that's still faster than speed limits elsewhere) on the Autobahns. Not because of safety but because of emissions. Just electronically ticket those going faster, so that the rich can keep going at 250Km/h, but charge enough money to get most people driving below the limit. But I reckon this would be like trying to take machine guns away from the US rednecks, there would be a revolt if someone tried to do it.

      Scrubbers on coal are positive, they remove the sulfur and other poisonous emissions, but the CO2 is still going out. I just found out those brand new plants emit 300Kg CO2 per second at peak load, or 4,7 million tons of CO2 per year if they are operated on average at 50% load capacity. That's 4,7 billion tons of CO2 yearly for one thousand of those (assuming they operate at a low capacity factor of 50%, in tandem with lots of wind and solar). You really need to look at the volume of coal a power plant burns, even the most efficient ones. An entire train filled with coal (like 150 wagons) every week.

      Germany turning off nuclear has already elicited responses from the Indians and Chinese that if they can do that, then they don't need to go nuclear quite as fast (keep burning coal), but their plants don't have scrubbers, don't use ultra efficient combined cycle turbines, and China is still starting up a few new coal power plants every month, and they aren't nearly as clean as Germany's.

As pointed out above a MSR does not care about the weather. MSRs can be placed just about anywhere that power is needed.

    Solar, wind, hydro, whatever are certainly welcome to attach to the grid to provide power in my world, I just don't see the need. Modern nuclear power could be so cheap and reliable that if allowed to reach it's full potential that I feel no other power source could compete.

Which obviously means if you want to sell peak energy in summer at 7PM you will sell nothing at all in winter at that time of the day :D However such a thing would make perfect sense for a beer garden which uses most of its power itself (and out door activity of that beer garden is closed in winter).

      The question how fast the wind needs to be depends on the turbines, they are designed for specific wind speeds.
      If you have your wind average at 30km/h, you use turbines suiting that average, then they will produce 100% (not 60%) of their rated power at that speed. (Offshore wind parks of the company http://enbw.com/ in the Baltic Sea e.g. produce roughly 4000h/y at 'rated' level and a bit more than 4000h/y 'above rated' level and about 300h/y they don't produce because of maintanance or to much or to less wind. So the mythical 'capacity' factor of those plants is above 100% Search on their web site, the pdfs covering this should be public available.)

      The lower the wind speed, the turbines accept, the more "time of the year" they produce power, but their peak production is less (IIRC).

      BTW: it is easyer to use m/s instead of km/h because that is usually the unit for the nameplates and easier to google (especially if you want to buy a turbine or want to know the average wind speed at a certain place on the world).

      German eletricity cost: US$ 0,46 / kWh
      American electricity cost: US$ 0,23 / kWh

      Just because Brazil could invest massively on Solar and Wind, the simple fact is those investments don't add up like the Green claim.

Take the subsidies off and those projects crash.

      Brazil has an extremely capable grid. We transfer tens of GWs for thousands of Kms. That makes sense for large hydro. It doesn't for electricity that costs 10x more.

      Thorium LFTR a "paper technology", humm, the core reactor characteristics have been demonstrated before I was born (I'm 41 BTW). The critical features outside the core are chemical challenges that good chemists could solve with a few dozen year-man effort. perhaps pessimisticly a US$ 10 billion problem to do the first research reactor, finalize commercial design, get the production line ready. Nobody is saying they can make LFTR happen in 1 year, but instead 2-3 years for a small scale research reactor and less than 10 years for the production line working. But there's zero point in doing this unless we get the nuclear paranoia out of people's heads. Unfortunately mankind waited until the scientists from the Thorium project at ORNL were all dead or getting senile before we tried to revive this tech.

      Thorium is essentially free fuel, cause it's an "undesirable" byproduct of rare earth mining, since we don't use it. There are dozen of rare earth mines that would each one produce as much thorium yearly than the whole world would need if it converted 100% of worldwide electricity production (and electrified 100% of the car fleet), and still replace 100% of fossil demand left from H2O + CO2 + a lot of heat (about 5000 tons per year, we could easily produce 100k tons per year). They can't operate cause the US EPA qualifies thorium as something dangerous, when you can put a 50g pellet of thorium in your pocket for years, and nothing will happen to you. I know because I sunbathed all summer long from age 9-19 in Thorium rich sands, primarily in a city known an Brazil's "city of health", people go to those sands for its therapeutic characteristics, exactly because of Thorium, Uranium and Radium. It's called Guarapari, and it's featured in Pandora's Promise.

      I said before Brazil electricity demand is close to 200GW, I was wrong, it's close to 100GW. Germany is 70GW. But 20 years from now Brazil is likely to need 150GW, and perhaps Germany will be 80GW tops.

We're building our 3rd nuclear station, about 1/10th the electricity production than the dam, but it's in a central location, a few hundred Kms from the 3 largest metro areas in Brazil, and we're now planning to build 5 or so new nuclear sites in the edge of the largest metro areas in Brazil (still in planning stages).
