U232 can be a bridge to aneutronic fusion power. I propose an aneutronic fusion reaction (Q>1) that uses D-T fusion to generate neutrons for the irradiation of Th230 so that U232 is produced. 230Th(n,y) -> 231Th(-B) -> 231Pa(n,y) -> 232Pa(-B) -> 232U U232 is the most radio productive among all the u...

http://www.inl.gov/pdfs/nantenna.pdf I hold great hope for this concept. From the abstract, it states as follows: A nantenna electromagnetic collector (NEC) has been designed, prototyped, and tested. Proof of concept has been validated. The NEC has moved forward further along in the product developm...

Now the question is how much better that Nanomaterial is (if it says it somewhere in that article, I cant read it anymore...grrrr). That link you provided works for me - and I don't have a subscription. Interesting stuff. Here are some related links: http://www.newscientist.com/article/dn13545 http...

If aneutronic B11-H fusion is not practical from either a technical or economic standpoint anytime in the near future, then D-T fusion is best served by a fusion/fission hybrid concept, and the Hilion reactor topology is well positioned for this approach. Any big project should be developed in well ...

Reference: http://www-ferp.ucsd.edu/PUBLIC/SNOWMASS/Energy-A.pdf The p11B fuel cycle avoids exotic isotopes, so that no breeding of fuel is required and the potential fuel supply is essentially unlimited. It is also nearly aneutronic, thus addressing materials damage and much of the materials activa...

Make the whole reactor out of diamond; it is cheap and will both conduct of insolate based on doping. It does not interfere with magnetism. Surround the reactor with a FilBe blanket. Run it at 700C for power removal and shielding (700C is the ideal diamond defect annulling temperature). This blanket...

Fusion and fission make a good couple; together they fill each others gaps. Fusion-fission hybrid reactors can be viewed as sub-critical nuclear fission reactors driven and controlled by an internal high energy neutron source; the fusion reactor. Such hybrids combine the natural neutron richness of ...

The fusion/fission hybrid power calculations are far higher than for just fusion. The FRC may work in fusion/fission hybrid mode with a fusion “Q” factor of less than 1. Fission is a huge energy multiplier. Using thorium and beryllium, for every fusion neutron produced, you get out 144,000 MeV therm...

It, is not that I oppose fission power. It is that I am dismayed by the cavalier attitued of orgaanzations/ nations that provide nuclear plants to costomers whith no or little real control over innapropiate operation of the plant. Certainly, any nation capable of building their own plants could use...

FYI: http://www-formal.stanford.edu/jmc/progress/chernobyl.html The Chernobyl accident occurred as a result of experimental use of a commercial reactor. This is crazy from the start. Making an experiment with the reactor which involved disabling its safety features . This is the single main cause of...

Re: optimum solution Good engineers will always freely acknowledge and admit mistakes and flaws in their approach as a prerequisite to their mitigation. Engineers continually obsess over mistakes and flaws as problems to be overcome, they think about them constantly, even loss sleep over them. On th...

I will address the thorium fuel cycle since it is highly proliferation resistant (I think proliferation proof) when coupled with fusion in preference to the uranium fuel cycle and its plutonium (a proliferation risk) byproduct. In other words, each D-D fusion produces one neutron that breeds 4 U233...

So, making a U233 bomb would be very difficult I would state it more strongly, it is near impossible to make a bomb out of U233 produced by fusion. Any terrorist or rouge nation would use PU239 instead; absolutely. I will now mention that U233 would be denatured. It would be contaminated with U234 ...

Fusion people would not use water as a blanket material. They would use either Lithium/lead or molten fluoride salts of lithium and beryllium and/or maybe sodium because of their nuclear properties and heat exchange advantages (High thermodynamic conversion efficiency) Unless fusion products find th...

I'm sceptical of the nonproliferation potential of thorium breeders. The Uranium 233 produced is not ideal for bombs, but I understand it might actually be easier to build. The Uranium 233 halflife limits the shelf life of the bomb- use it or lose it. And it fissions too easily. I understand only a...
