| Abstract |
| The reference fuel for operating and forthcoming prototype and commercial
liquid metal cooled fast breeder reactors (LMFBR) all over
the world, including India, is mixed uranium plutonium oxide (MOX).
Mixed uranium plutonium monocarbide (MC) and mononitride (MN)
are considered as advanced LMFBR fuels. Powder-pellet (POP)"
is the conventional method for production of MOX, MC and MN
fuel pellets starting from U02 and Pu02 powders. The POP route
involves generation and handling of plutonium bearing fine powder or
dust particles which has the problem of radiotoxic dust hazard.
Further, fine powders have poor flowability which makes automation
and remote fabrication difficult. The combination of ammonium
uranyl plutonyl carbonate (AUPuC) process and low temperature
oxidative sintering (LTS) minimises the radiotoxic dust hazard and
the fabrication cost of MOX fuel and is considered as advanced POP
route. |
