Thorium reactor design

Continuous spiral flow thorium molten salt breeder reactor
  (+2)

A cylinder with a spiral shaped guide inside directs the flow of Thorium salt around a central core, where it is extracted for purification and resupply of fresh Th fuel by florination etc; and the fresh molten salt is re-added to the outside of the spiral.

The core is equipped with a neutron source such as an accelerator, or alternatively U salts are added at a single or several points towards the core of the spiral coil.

As the salt works its way around the spiral and towards the center it becomes more fissile, and is finally burnt up as it reaches the center in a well balanced reaction. The speed of flow and length of the spiral helps to moderate the reactor and maintain the correct ratio of Th/U at various points of the spiral.

Gas and unwanted isotope etc. buildup could be alleviated by extraction directly into the spiral from above.

The whole cylinder is immersed in a heat transferring medium, eg. air.

       Interesting, but I need a little background on the reactions to get this...

       [peterpeter], one of the 'bakery's more discrete players - thirteen annoed ideas and eight ideas of his own in eight years.   

       Sometimes I feel like one of those sportscasters - "Frank, that's only the third time a player has run for 43 yards in the second quarter on a Monday night."

       Hang on, I've run out of thumbs again... so shooting the Thorium through fast means a smaller output, yes ?

       The Molten Thorium Salt Reactor is a well studied breeder design. The difference with this one is the development of hot spots.

       Not that I've bothered to look it up, but this design is to minimize radioactive emission: the new salt being introduced to the outside of the ball blocks the emissions of the fissing salt further on through... or something like that.

       The real problem here is there are all sorts of fission products being created, and some of them probably need to be continuously removed (gasses, for instance), while this idea seems to envision a very slow flow, almost one pass situation.

       The above comments have been used to rewrite the idea (originally a ball -- now a spiral), thank you for your help!
