<p>PROBLEM TO BE SOLVED: To reduce reprocessing quantity by separating minor actinides from rare earth element and efficiently utilize minor actinides for fuel without giving large impact on a recycle system by a wet reprocessing. SOLUTION: Spent fuel 5 from a light water reactor core 3 separates Pu, Np by an improved Purex process 6 and minor actinides(MA) and rare earth element (RE) are separated into FD except for RE and a mixture of MA and RE by a Truex process 8. The MA and RE are separated by a metal reduction process 9 and the MA is used for fuel of a specific fuel aggregate 11. The specific fuel aggregate 11 is loaded in a fast reactor core 4 so as to be driven. The spent specific fuel aggregate 12 is separated into RE (most of them), and MA, RE (some) by an MA recycle system 2 by an electrolytic purification 10. Though the core fuel aggregate 7 is loaded in a fast reactor core 4, it is returned between the light water reactor core 3 and the spent fuel 5 by a core fuel aggregate recycle system 1 after the drive.</p> |
