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.

Fusion-fission hybrid reactor in a long term energy resource strategy is described briefly.Capability of electricity and fissionable material production of a hybrid reactor consisted of typical fusion reactor core and blanket is analyzed emphatically.Capability of electricity production of composite fuel cycle system of hybrid and satellite reactors (e.g.PWR) is studied.Related calculations show that a natural uranium fueled and water cooled blanket is economical and less technical risk.
