Potential Solution for Storing Nuclear Waste

02/17/2010 11:10 AM

GE Hitachi's Answer to Nuclear Waste

The maker of nuclear power plants is promoting a process to use the waste as fuel.

GE Hitachi Nuclear Energy, one of the world's biggest providers of nuclear reactors, says it has an alternative to burying nuclear waste at Yucca Mountain in Nevada, the proposed waste repository that the Obama administration has said is now "off the table." Based in Wilmington, NC, GE Hitachi wants to use nuclear waste as a fuel for advanced nuclear power plants, significantly reducing the volume of waste and the length of time that most of the waste needs to be stored.

(I am not an expert in the field.)

Seems, if the splitting of atoms (fision) should go on till the final outcoming items should be safe non radiating atoms. Then only the problem of nuclear waste will be elliminated.

It sounds good except for these two sentences:

"The first group consists of the products of fission that can't be used as fuel in nuclear reactors--these will need to be stored, but only for a few hundred years, rather than the tens of thousands of years that other nuclear-waste materials need to be stored."

"Although it could reduce nuclear waste and provide a valuable fuel source for nuclear power plants, the GE Hitachi technology would not completely eliminate the need for long-term storage, Forsberg says, because perfect separation of the components of nuclear waste isn't possible--there will always be some fraction of the material that needs to be stored for more than 10,000 years.Although it could reduce nuclear waste and provide a valuable fuel source for nuclear power plants, the GE Hitachi technology would not completely eliminate the need for long-term storage, Forsberg says, because perfect separation of the components of nuclear waste isn't possible--there will always be some fraction of the material that needs to be stored for more than 10,000 years."

It's hard to slide by those statements. Just think of how much more will be stored during those hundreds of years. It would be great to have nuclear power plants, but, until the waste is made safe within a relatively short period (say, 25 years), the risk isn't worth it.

Have some fun today,

I'm exactly a fan either

Good to have the discussion though...

There are several Guy's & Gals who actually know this stuff, 'round here, who will note the lack of technical detail in the proposal [should they show up].

My personal favorite questions designed to incite are:

Is the process safe enough that you would let your daughter of childbearing age work in the maintainance or disposal depatments?

Is it OK to have a few people take one for the team & be exposed to greatly elevated levels of radiation, for what is otherwise a safe & efficent scheme?

One positive I would note is using what is in effect a "breeder" process, would greatly reduce the need for further mining, another area of workplace exposure.
