The code allows simulation of key facilities of the external fuel cycle (fuel fabrication and reprocessing facilities, SNF storage, uranium, plutonium, neptunium, americium and curium stores, RW long-term storage sites), nuclear reactors, including RBMK-1000 rexisting existing and advanced VVER reactors (using different fuel types), and fast reactors (both existing and innovative).
The fuel fabrication and reprocessing facilities were operational, and two much larger reactors were under construction. .

Results rely on natural uranium supplies, fuel fabrication, spent fuel reprocessing, quantities of proliferating materials and the opportunity of a rapid deployment of fast reactors (FBR).
I is commonly either the top or among the top risk drivers, along with Tc, at radiological waste disposal sites and contaminated groundwater sites where nuclear material fabrication or reprocessing has occurred.
Transmutation of the manmade actinides and longlived fission products will require advanced technologies e.g. regarding reprocessing losses, remote fabrication techniques, and most probably, isotope separation processes.
Full recycling of TRU isotopes can, in theory, lead to a reduction in repository radiotoxicity to reference levels corresponds to the radiotoxicity of the unburned natural U required to fuel a conventional LWR in as little as ∼500 years provided reprocessing and fuel fabrication losses are limited.
The circulation of the fuel in this way eliminates the need for fuel fabrication and allows for continuous online reprocessing.
Carter hopes to slow down in this country and others the further spread of the technology for reprocessing spent uranium to yield plutonium, suitable for the fabrication of nuclear weapons.
The principal steps of the fuel cycle include uranium mining and extraction from its ore (processing), uranium enrichment, fuel fabrication, loading and irradiation in the reactor (fuel management), unloading and cooling, reprocessing, waste packaging, and waste disposal.
