Depends on size of course, but a typical case would be about 75 tons total, with about 25 tons being changed every two years.
The handling of many tons of fuel as opposed to a few truckloads of uranium, the production of carbon dioxide and sulfur dioxide, the disposal of many tons of ash, the mining of the coal which can be dangerous and has caused many accidents, and possibly the cost of the fuel relative to uranium though that depends on how easily the coal can be obtained.
The number you are asking for (the critical size) varies dramatically with reactor design and fuel enrichment level, a large power reactor may need thousands of tons of yellowcake while a small research or medical reactor could operate on as little as about 1Kg Highly Enriched Uranium.Some examples of actual reactor fuel loads:X-10, 54.1 tons slightly enriched Uranium metalNRX, 10.5 tons natural UraniumSUPO, 870 grams 88.7% enriched Uranyl Nitrate in water solutionCalder Hall, 130 tons natural UraniumShippingport, 14.16 tons natural Uranium yellowcake & 75Kg Highly Enriched Uranium metalAHPR, 90Kg highly enriched Uranyl Sulfate & Uranyl Nitrate in water solution
Yes; the average nuclear power plant yields about 3 tons of radioactive waste each year.
13200 tons in 13200 tons
About 1500 tons of coal
about the same as any other power plant nuclear supplies the heat to boil the water to run the turbine to turn the generator 90 tons of uranium doesnt take as many barges as 252,000,000tons of coal so the plant doesnt need to be built by a river can be inland with only road access
A typical large power reactor will have approx 75 tons of uranium fuel with about 1/3 of this being changed every two years
tenure
almost none
Approx. 70 000 kg day.
This depends on the type and power of the reactor; say tens of metric tons.
That depends on what substance the question refers to. For example . . . Gold: very few tons Diamonds: even fewer tons Enriched uranium: several tons CO2: copious tons Trash: megatons
tens of thousands tons each year
1.1112007E31 or 1.1112007 x 1031 tons.
690 tons
This is taken from Wikipedia, about India and nuclear power Uranium used for the weapons program has been separate from the power program, using Uranium from indigenous reserves. This domestic reserve of 80,000 to 112,000 tons of uranium (approx 1% of global uranium reserves) is large enough to supply all of India's commercial and military reactors as well as supply all the needs of India's nuclear weapons arsenal. Currently, India's nuclear power reactors consume, at most, 478 metric tonnes of uranium per year. Even if India were to quadruple its nuclear power output (and reactor base) to 20GWe by 2020, nuclear power generation would only consume 2000 metric tonnes of uranium per annum. Based on India's known commercially viable reserves of 80,000 to 112,000 tons of uranium, this represents a 40 to 50 years uranium supply for India's nuclear power reactors (note with reprocessing and breeder reactor technology, this supply could be stretched out many times over). Furthermore, the uranium requirements of India's Nuclear Arsenal are only a fifteenth (1/15) of that required for power generation (approx. 32 tonnes), meaning that India's domestic fissile material supply is more than enough to meet all needs for it strategic nuclear arsenal. Therefore, India has sufficient uranium resources to meet its strategic and power requirements for the foreseeable future.
(Another contributor wrote:)Carbon dioxide (CO2),Sulfur dioxide (SO2),Nitrous oxide (NOx), uranium oxides, etc. go up the stack into the atmosphere.Clinker and ash remain in the fire box and have to be removed and disposed of.Tens of times as many tons as any nuclear plant.
