nuclear energy

Facts

Nuclear power is cheap and emission free but following fears of meltdowns and concerns about waste disposal, it is also vastly unpopular. Yet in spite of the environmental concerns it raises, nuclear energy still has huge economic viability and so remains an issue with states that are always searching for more affordable energy alternatives. Nuclear power plants also come up as a security concern, in spite of claims that power plants are largely terrorist-proof.

Energy produced

How much of our energy is nuclear energy (2002):

  • 20% of our electricity (EIA);
  • 8% of all energy (EIA).

Cost of nuclear energy compared to other energies

(using 1997 info) (EIA)

  • Nuclear fuel: $0.51 (per million Btu).
  • Coal: $1.31 (per million Btu).
  • Coke coal: $2.95 (per million Btu).
  • Natural gas: $4.62 (per million Btu).
  • Petroleum: $7.82 (per million Btu).

Waste

Two kinds of nuclear waste (NRC):

  • High-level waste is the "spent" nuclear material that is no longer usable but is still highly radioactive.
  • Low-level waste is material that has been exposed to nuclear material (clothes, etc.) that is now "contaminated."

How much nuclear waste we produce now:

  • Low-level waste: about .3 million cubic feet a year (2000) (NRC), or 1 - 2 million cubic feet (NE) (out of a total of 350 billion cubic feet of garbage Americans produce each year).
  • There is currently a total of about 49,000 metric tons of high-level waste. (OCRWM) (OCRWM says this is the equivalent of a football field piled ten feet high with nuclear waste.)

What we do with the high level waste:

  • All high-level waste is now being stored in about 130 temporary sites (usually at the nuclear reactors) in 39 states (OCRWM), at a cost to the Energy Department of $500 million a year (NYT).
  • The only current plan in the works for long term storage is to store high-level waste in Yucca mountain (up to 70,000 metric tons), but that plan is years behind schedule and still slowed by political and legal battles. (OCRWM) A private company, Private Fuel Storage, announced in 2006 that it will build its own spent fuel repository. (NYT)

The half life of common nuclear waste (half life is the length of time it takes half of a batch of nuclear material to naturally decay) (NRC):

  • Cesium-137 and strontium-90: 30 years;
  • Plutonium-239: 24,000 years.

For more information on kinds of nuclear waste, see US Nuclear Regulatory Commission.

Where the facts are from:

Did we miss something, let some slant slip in, lose a link - or do you just have something to say? Drop a line below! In the spirit of open dialogue, cJ asks you keep it civil, keep it real and keep it focused on the message, not the messenger. See our policy page for more on what that all means.

Yucca Mountain Safety

It seems that most of the Presidential candidates, in order to win Nevada voters, are now against using Yucca Mountain. My understanding is that we have spent Billions studying the geology, that it is the most closely studied piece of real estate in the world, and that it is by all rational accounts a safe place to store the spent fuel rods. I do not believe that it can be argued that it is not much better to place the spent reactor fuel in Yucca Mountain than to leave it in the storage facilities of the reactors all over the country. So, my question to you is: Shouldn't this web site go over the available science, and explain to us why or why not Yucca Mountain is or is not the best choice for nuclear waste.
