S.M. Lee et al. (Paper 32)

The average discharge burn-up for a 160 day refuelling cycle is slightly less than for a 240 day cycle because of rounding errors; for example, sub-assemblies reaching optimum burn-up in 240 days have to be removed at 160 days.

The requirement for a 10 kg/day combined capacity for reprocessing and fabrication plant is necessary as reactor throughput is ^ 10 kg/day; otherwise there will be build up of fuel in the fuel cycle. In case there is parallel processing for the refabrication and reprocessing plants, the individual plant capacity will be 10 kg/day. In case both plants have successive batch processing, the independent plant capacity will be 20 kg/day but the effective combined capacity of the two plants will remain at 10 kg/day.
