[en] Electricity growth rate in India in 1999-2000 improved compared to the previous year and the installed electric capacity reached 97.5 GWe, with about 2 GWe nuclear. The nuclear power plants performed very well with average capacity factor of over 79%. Two new 220 MWe reactors, Kaiga-2 and RAPS-3, were commissioned during the year. FBTR was operated at various power levels up to 12.5 MWt and a peak burnup of 51500 MWd/t achieved. Test irradiation of Zr-Nb pressurized capsules were completed in FBTR for the PHWR programme. Detailed design and technology development for PFBR were continued. Review of the chapters of the PSAR by two level safety committees was continued. The 'rapid' environmental impact assessment report was prepared and measurements for the detailed report are in progress. R and D in reactor physics, shielding, engineering development, safety engineering, structural mechanics thermal hydraulics, instrumentation, metallurgy, non-destructive evaluation, chemistry and reprocessing were continued. These include cover gas heat transfer, sodium heaters, sodium pumps, drive mechanisms, flow restrictor devices, buckling damage, sodium-concrete interaction, activity transport in sodium, fuel development, materials testing and characterisation, corrosion measurements and electrochemical meters.
