Nuclear Power NUCLEAR POWER PLANT - NUCLEAR PROLIFERATION (2 of 2 quizzes)
{ Nuclear power plant-Life cycle } {In a PWR reactor, the water is kept under high pressure } + to prevent it from boiling - only in the reactor core - to slow down the neutrons - to reduce the heat required to boil it { Life cycle } {Fuel rods spend typically ______ total now inside the reactor, generally until _____ of their uranium has been fissioned} + 6 years;  3% - 6 months;  30% - 6 months;  3% - 6 years;  30% {After about __________ in a spent fuel pool the spent fuel can be moved to dry storage casks or reprocessed.} - 5 months - 50 years + 5 years { -Conventional fuel resources } {Uranium is approximately ______________ than silver in the Earth's crust.} - 40 times less common - 4 times more common + 40 times more common - 4 times less common {Reactors that use natural (unenriched) uranium are} - considered impossible + are already in use - are likely to emerge in the next few decades { -Breeding } {Fast breeder reactors use uranium-238, an isotope which constitutes _____ of naturally occurring uranium} - 30% - 3% - 1 % + 99% - 60% {One concern about fast breeder reactors is that the uranium reserves will be exhausted more quickly} - true + false { -Solid waste } {High-level radioactive waste management is a daunting problem because} - they cannot be stored underground + the isotopes are long-lived - the isotopes are short-lived {A 2008 report from Oak Ridge National Laboratory concluded that the dose to the public from radiation from coal plants is ___________ the radiation nuclear plants (excluding the possibility of accidental discharges of radioactive material} - 10 times less than - about the same as + 100 times more than - 10 times more than - 100 times less than {A 2008 report from Oak Ridge National Laboratory concluded that the dose to the public from radiation from properly run nuclear plants is ___________ the radiation created by burning coal} + 100 times less than - 100 times more than - 10 times less than - 10 times more than - about the same as {One concern is that long term nuclear waste management is now being performed by a number of private waste management companies} - true + false {The Waste Isolation Pilot Plant in New Mexico } - can no longer nuclear waste from production reactors because it is full + is currently taking nuclear waste from production reactors - was originally a research and development facility but is now under private ownership { - Reprocessing } {In the United States, reprocessing of spent Uranium} - provides 5% of our fuel needs which is consumed within the United states + is not allowed due to nuclear weapon proliferation concerns - is not allowed due to waste management concerns - provides 20% of our fuel needs and allows the United States to export nuclear fuel {The reprocessing of spent Uranium worsens the problem of long term waste storage} - true + false {The reprocessing of spent Uranium helps alleviate the problem of long term waste storage} + true - false { Economics } {Nuclear power plants typically have} - low capital costs and high fuel costs + high capital costs and low fuel costs - high capital costs and high fuel costs - low capital costs and low fuel costs { Accidents and safety, the human and financial costs } {How many latent (cancer) deaths are estimated to result from the Three Mile Island accident?} + zero - from 4000 to 25,000 - from 0 to 1000 {It has been estimated that if Japan had never adopted nuclear power, the use of other fuels would have caused more lost years of life.} + true - false {It has been estimated that farmland lost due to Fukushima accident will be again useful for farming in 40-60 years} - true + false {It has been estimated that farmland lost due to Fukushima accident will not be farmed for centuries} + true - false { Nuclear proliferation } {The Megatons to Megawatts Program} - purchases spent fuel that could otherwise be used to make weapons, and is considered a failure - converts weapons grade uranium into fuel for commercial reactors, and is considered a failure + converts weapons grade uranium into fuel for commercial reactors, and is considered a success - purchases spent fuel that could otherwise be used to make weapons, and is considered a success
