Abstract：
The transmutation of nuclear waste ¹²⁹I in the subcritical system was studied in the present work using both theoretical and experimental methods. In the experiment, the energetic proton beam (1.0 GeV) form accelerator was used to bombard a thick lead target. And the long lived nuclear waste ¹²⁹I was transmuted to ¹³⁰Xe by the spallation neutrons generated in the target. The transmutation efficiency of ¹²⁹I was compared with theoretical simulation. And the transmutation in an Accelerator Driven Subcritical Fast Reactor (ADSFR) was explored with the experimental results. The spent fuel of PWR (Pressured Water Reactor) is assumed to be used as the fuel in ADSFR. The liquid lead was chosen as target and coolant in the ADS.
