Nuclear waste disposal by reducing the long lived isotopes to short lived isotopes by nuclear transmutation

Technically proven safe disposal of the nuclear waste is geological disposal. After 300 years major isotopes are ¹³⁷Cs, ⁹⁰Sr, ²³⁹Pu, ²³⁸Pu, ²⁴¹Am, ¹⁵¹Sm, ²³⁹Np, ⁹⁹Tc and ^137mSa. After 10,000 years major isotopes are ²³⁹Pu, ²⁴⁰Pu, ⁹⁹Tc, ²³⁹Np, and ²⁴³Am. After 1, 00,000 years major isotopes are ²³⁹Pu and ⁹⁹Tc. The geological disposal depends on the time the spent fuel takes to decay. The disposal repository capacity is constrained not by volume but by heat generation. The spent fuel can be reprocessed through a fuel cycle to recover and re-use Uranium and Plutonium. Our country's reprocessing program plans to include both U and Th fuel cycle in order to minimize the transuranic wastes. As an alternative to geological disposition and reprocessing is the transmutation of the spent fuel which can change the long-lived isotopes to short lived ones
