INVERSE PROCESS OF RADIOACTIVE WASTE ELIMINATION IN ADS

Along with the development of energy gain in the Energy Amplifier (EA) system proposed by C. Rubbia [1], solving the problem of destruction all actinide elements by fission is considered.
This system transforms LLFFs (Long Lived Fission Fragments) into short-lived or stable elements [2-4]; as well as transforming stable elements into radioactive elements. Therefore, we can’t exclude that the “inverse” process may occur while ADS is being operated.
In this work, we use semi-empirical formulas established from the TARC experiment [5] to calculate the transmutation rate of the short lived or stable elements 134Cs, 136Cs, 92Mo, 92Z and 78Se into the long lived radioactive elements. The transmutation rate trth of 134Cs, 136Cs and 78Se is rather high. This demonstrates that these isotopes are able to capture neutrons in the high resonance region and that EA can transform them into long- lived isotopes. We offer suggestions to resolve the inverse effect for destruction of LLFFs in ADS.
