Abstract: We propose a method of burning high-level transuranic waste combining with Th-U fuel cycle in a subcritical reactors driven by external fusion neutron sources. Corresponding one-dimension model is built by means of ONESN_BURN code with new data libraries. Numerical results, including actinide radioactivity, biological hazard potential, and high burn-up rate of high-level transuranic waste are obtained. Comparison with thermal reactor shows that the harder neutron spectrum is the more efficient than the soft one.

Key words: high-level transuranic waste, burning actinide, fusion fission reactor, Th-U fuel
