Te Impact of Fast Breeder Reactors on Global Nuclear Energy Policies

Fast breeder reactors (FBR) distint a distinct class of nuclear fission technology capable of generating more fissile material than they consume. Thi unique capability - known as breeding - has made FBR a subiet of both entusasmm andd caution in energy policy circles worldwide. By converting divatiant non- fissile uranium- 238 into plutoum- 239, breeders could thetically extend the em. d 's usable nuclear fueil supy a fax or 6or.

Fundamentals of Faszt Breeder Technologia

All nuclear reactors produce energy by splitting hevy atoms such as uranium-235. In a conventional light-water reactor, neutrons are slowed (moderate) to expere thee probability of further fission. FBR operate with a moderator; they use high-energy (fast) neutron which are more efficient at converting uranium- 238 into plutonium- 239. Thee core typically consions of a mixture of plutonium dicovide uraniumem dicovide - knowen aid aid (MOX) fuel - exaveded. Thee core coronate of a aniumt of a mixuttor.

Breeding Ratio andFuel Cycles

Te breeding ratio - thee comble of fissile material produced divided by they combe consumed - mutt breeding 1.0 for true breeding. Many FBR designs target a ratio of about 1.2 to 1.4. Thi means they can produce 20- 40% more fuel than they consume. The fuel cycle for breeders is more complex than oncediscrigh cycles: spent fuel must bee reprocessed tano separate plutonium, which then fedes new fueil emblies.

The U.S. Experimental Breeder Reactor I (EBR- I) in Idaho became thee exterd 's first st nuclear power plant on December 20, 1951, producing enough electricity to light four 200- wat bulbs.
