If we switched solely to nuclear power, and assuming we only mine more uranium and don’t build breeder reactors, how long could fuel reserves meet global energy demand?
>>17085086Few decades with conventional reactors, few millennia with breeder reactors.
>>17085086There's currently about 100 years of uranium resources left, nuclear makes about 5% of the primary energy demand so about 5 years of uranium at 100% energy use.
How much would California benefit from a dual-purpose nuclear power/desalination plant built at the site of the old Diablo Canyon plant?Assuming funding wasn't an issue.
>>17085167It would have to be earthquake and tsunami proof.
>>17085086About a million years
>>17085086Reserves or known reserves?
>>17085106And is that assuming other stayes don't have their own nuclear build up?
>>17085086Even excluding seawater extraction, there's plenty of uranium in the crust that we could feasibly extract. At current consumption we'd be good indefinitely, the future might be an issue if we're limited to mining simply due to the rate at which we discover and exploit deposits.
>>17085086If you go by the Red Book's lowball estimate for uranium consumption, we'll run out of all reserves that could theoretically be mined for under $260/kgU by the year 2074. I'd run numbers for the case where government pledges actually come true (which includes jeets, niggers, pinoys), we'll run out by 2064. >>17085552All of these numbers are for known reserves (places with actual mines, reasonably assured resources and inferred resources). Reasonably generous. This is also assuming China doesn't build insane uranium reserves the way they did for petroleum, or whatever other cards they have up their sleeve. I suggest you pull up the Red Book and play around with it a bit.
>>17085086Or we could just lower the amount of brown people in general.
>>17086882yeah I was about to post this, why do we need to keep up energy production and piss through resources because 3rd worlders overbreed again? the world population should be 5% of what it is
>>17085086doesnt matter. At the lowest point humanity will huddle around hydroelectric plants with a 500 million population eternally in balance
>Today, the world’s nuclear fleet burns roughly 65,000 tonnes of natural uranium per year.Decade maybe.
>>17086882They use up the least amount of resources overall though.>>17087190>why do we need to keep up energy production and piss through resources because 3rd worlders overbreed again?But developed states are who are burning through resources. You think some .iddle class family in Ethiopia polluted or consumes as much as a household in Arizona that uses AC with the windows open?
hundreds of years of uraniumthousands of years of thorium
>>17087435>They use up the least amount of resources overall though.They use about the same amount of resources for food and the fuel required to distribute it. Humans tend to eat a similar amout of food everywhere, between 2900 and 3800 calories a day.
>>17087462>They use about the same amount of resources for food and the fuel required to distribute itNo they don't. Poor people use significantly less resources on food (like an order of magnitude less) simply because they are you know poor and can't afford food shipped in fresh from across the world and just eat local in season products and mostly plants at that.
>>17087464>they are you know poor and can't afford food shipped in fresh from acrossThey eat grain and meat fed with grain like everyone else. The concept of fresh isnt relevant here
>>17087464Billions are fed like this. The grain is turned into pasta and bread, and fed to chickens. Onions flour added to increase the protein. Quiet a lot of calories come from seed oils and corn syrup.
>>17087473Ethiopians consume about 25 times less meat than Americans. The same goes for everything else that has high energy inputs per calories like imported fruits, foreign specialties etc. You simply can't get the around the year fresh products in an Ethiopian supermarket that you can get in an American one and they don't magically appear in the supermarket, they have to be shipped and stored which costs energy and resources and the things rich people eat just cost straight up more resources to produce too, meat consumes way more land than plants, specialty plants consume more than basic grains and vegetables etc, imports cost more than domestic production etc. The energy that goes into making and transporting their food is simply substantially less. This is a stupid hill for you to die on.>>17087474Billions of poor people yes. The land use and fossil fuels required to feed one poor person is much less than the same to feed a rich person. It's just a fact.
>>17087462>2900 and 3800 calories a dayI was going to call you a burgerfat, but the numbers actually show that to be trueWhy is everyone eating so much? Isn't 2000 a day supposed to be the nutritional standard?
I want to be around humanity at rest energy after they glowed enough to emit star constants in procedural ordering.

>>17087462>They use about the same amount of resources for food and the fuel required to distribute it.False. Developed world market demans and wastage is astronomical. Now combo that with electrical waste and overuse and the gap between both groups is outright immense. The average UK fridge uses mote power in one month than a family in Mali does in a year.
>>17087489The demand for year round fruit and foreign veggies/fruits or coffee cannot be downplayed. No one ever cares to acknowledge it because everyone got so used or entitled to it as a "permanent" staple and the fact that many people tie their statuses and egos to being able to spend $$$ on them
>>17087871>. Developed world market demans and wastage is astronomical.nonsense, the alleged waste is in perishable fruits and vegetables, which are an insignificant fraction of the diet. The bulk of the diet is meat, dairy, grease, sugar and grain. Not some delicate green that wilts in a day if it isnt sold.
>>17086882>>17087190>>17087462>>17087871fat amerimutts are the ones that have the highest per capita energy consumption in this planet. even higher than china, which is basically a big ass factory.>Humans tend to eatthis has nothing to do with nuclear energy plants, RETARDSyou "guys" (assuming these are not bots) obviously don't belong here if you are unable to do a fucking google search or conflate totally different things to push for fake arguments.
>>17087877>the alleged waste is in perishable fruits and vegetablesAnd a fuckton of other stuff anon. Most shit within and outside produce is thrown out. The system is extremely inefficient and leads to massive problems up and down the logistics chain.>The bulk of the diet is meat, dairy, grease, sugar and grain.Only for fatasses and people who think eating meat and dairy is a status symbol and aping unhealthy diets.>>17087881>fat amerimutts are the ones that have the highest per capita energy consumption in this planetMany many other developed statea have high consumption and waster output per capital too. Pinning it on just the Americans is an extremely foolish line to push.
>>17087917>Only for fatassesIt still the bulk of the diet. The general population isnt living on avocadoes or lettuce. People eat dairy, meat, grain, grease and sugar. The most common vegetable is potatoe, most common fruit are oranges, consumed as juice.
>>17085106>few decadesmuch, much more since there is no much search for uranium mines, it's too cheapalso there is a fuckton of unconventional sources
>>17087999>also there is a fuckton of unconventional sourcesNamely the oceans. In which case it might as well last forever.
>>17087622>aliens come to Earth seeking intelligent life>they land in Poland
>>17088158better than landing in snowgeria.
>>17085086You don't need breeders, a multi-cycle reprocessing strategy combined with a fast reactor fleet will allow us to burn our depleted uranium for centuries to come. And that's not counting all the unmined reserves, both known and unknown. The bigger issue with a "solely nuclear" generation is that nuclear is too inflexible to adjust to demand. You need something that can be easily turned on and off to follow peaks and lulls.
>>17087935>It still the bulk of the dietand that's why their bidy systems are so fucked up and healrhcare system suffers for it.
>>17090464So just build throttles, for load following. Frog reactors were mandated to have them, IIRC.
>>17087877t. has never looked into a supermarket dumpsterthey usually have one filled to the brim with bread/pastries that are a day old and arent sold because they are "stale" and the e costumer expects the shelfs to be filled until closing time. theres also plenty of dairy, meat and packaged stuff that gets to close to the bestby date. fresh fruit and veggies are maybe 1/3rd of the overall volume.
