A major parameter to quantify this performance is the number of high-level waste (HLW) glass units generated per GWd (gigawatt-day based on reactor thermal power Fuel cycles have always been of key strategic importance to the nuclear industry to form MOX fuel, which can be effectively utilized in CANDU. AECL has performed extensive studies on the use of MOX fuel in CANDU in collaboration with an overseas client.

The mixed oxide fuel proposed by Shaw AREVA MOX Services (formerly Duke COGEMA Stone & Webster (DCS)) is a blend of plutonium dioxide and depleted uranium dioxide that will be used as fuel in commercial nuclear power plants. Depleted uranium is a byproduct of the uranium enrichment process.

Mox has been used in France since 1987. At present, a partially closed fuel cycle is operated in some countries, notably in France.

With the Th-U cycle, doubling times values are only slightly higher than those predicted for solid-fuel fast reactors working in the U/Pu cycle (in the range 40–60 years). The characteristics of different launching modes of the MSFR with a thorium fuel cycle have been studied, in terms of the safety, proliferation, breeding, and deployment capacities of these reactor configurations [10].

Spent fuel is reprocessed and the plutonium is mixed with uranium and reused in so-called MOX fuel (mixed oxide fuel) in existing thermal neutron reactors. The spent MOX fuel is then stored, pending reprocessing for future use in fast neutron reactors. Japan Nuclear Fuel Ltd. （JNFL）applied for the approval of nuclear fuel material processing to construct the MOX fuel processing facility for light water reactor （LWR）“J-MOX”at Rokkasyo-mura, Aomori Pref. in April 2005.

Fuel cycles have always been of key strategic importance to the nuclear industry to form MOX fuel, which can be effectively utilized in CANDU.
