Nuclear power plant-Life cycle

1 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

2 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%

3 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

4 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

5 Reactors that use natural (unenriched) uranium are

	considered impossible
	are already in use
	are likely to emerge in the next few decades

-Breeding

6 Fast breeder reactors use uranium-238, an isotope which constitutes _____ of naturally occurring uranium

	30%
	3%
	1 %
	99%
	60%

7 One concern about fast breeder reactors is that the uranium reserves will be exhausted more quickly

	true
	false

-Solid waste

8 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

9 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

10 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

11 One concern is that long term nuclear waste management is now being performed by a number of private waste management companies

	true
	false

12 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

13 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

14 The reprocessing of spent Uranium worsens the problem of long term waste storage

	true
	false

15 The reprocessing of spent Uranium helps alleviate the problem of long term waste storage

	true
	false

Economics

16 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

17 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

18 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

19 It has been estimated that farmland lost due to Fukushima accident will be again useful for farming in 40-60 years

	true
	false

20 It has been estimated that farmland lost due to Fukushima accident will not be farmed for centuries

	true
	false

Nuclear proliferation

21 The Megatons to Megawatts Program
