I've considered this scenario quite a bit. I'm curious as to the viability and sustainability of a cycle in which a Pebble-Bed Nuclear Reactor uses recycled Plutonium-239 from a Fast Breeder Reactor to generate power, and has its waste material fed into the same Breeder for recycling. In theory, this should produce limitless amounts of electricity at very little risk, especially if the scant amounts of unrecyclable waste products were treated accordingly and buried.

Yes, your understanding is quite correct Nygdan. However I do not believe recycling the waste is a bad thing, in fact it is very efficient. Have a look at the link below for a story on French nuclear energy. There nuclear plans started on a large scale in the seventies due to oil problems in the middle east.

Nuclear production accounts for 76% of Frances electricity and Hydo power accounts for I believe around 12%, thats pretty dam (excuse the pun) impressive. They certainly are clued up when it comes to energy production.

Vitrification consists of the mixing of calcined waste with borosilicate glass grit. This is melted in a specialized furnace and cast into a mold. Borosilicate glass is considered a suitable matrix for nuclear waste because the glass has strong interatomic bonding but not a strict atomic structure. Because of this, it is able to contain a variety of different elements. Under running or standing water, radioactive products leak out at a very slow rate. In addition, the glass is resistant to structural damage from radiation.

It seems to a very safe and effective way to store waste. France has always been one step ahead when it comes to waste reduction and storage. They had already thought about good ways to do it before they started mass production of nuclear facilities, something it sems the rest of the world had not thought about as much.

I haven't looked at the recycling of nuclear waste, however the following provides some options in reducing the radioactivity of the waste:

I also believe Henry T Moray looked at/could transmutate radioactive waste into something else...couldn't find a link though.

I support the French for the innovation of nuclear waste disposal. The combination of the waste into glass seems like a good idea. I believe the same technique has been examined for Yucca Mountain.

Nuclear reactors that produce plutonium (known as breeder reactors) are more efficient in energy production than the slow neutron reactors in wide use. However, unless the spent fuel is reprocessed and added back to the reactors the gain for waste with a shorter half life will not be achieved. A half life is the time it takes for a radioactive material to become half of what it was when it started.

When looking at this proposal of reprocessing radioactive waste note that "real people" have to take part in the processing. The drawbacks of this are that you will have people who have access to plutonium which is one of the most hazardous and toxic elements known to man. Also, these people will be putting themselves at risk of being exposed to radioactivity. And, every tool used to process the waste will become radioactive from fast neutrons or need to be decontaminated.


further reading
The design of fast-breeder reactors poses greater safety problems than those of other reactor types. The challenge is to develop a safe fast-breeder reactor that is economically competitive with thermal (slow-neutron) reactors, even when the lower fuel costs are accounted for. Currently the price of natural uranium and enrichment is not high enough to justify the additional costs associated with the use of breeder reactors. Thus, breeder reactors are more complex than other types of reactors and raise concerns about the proliferation of plutonium.
