World nuclear news – EDF’s nuclear power plants in France and the UK generated 421.1 TWh and 55.8 TWh respectively, beating targets and up on 2010 performance by 13 TWh. The UK’s Advanced Gas-cooled Reactor fleet posted its best performance for six years.
One factor in the year-on-year increase in nuclear generation was the reduction of unplanned outages by a total of 594 days. The ending of long outages at Heysham and Sizewell B also helped, and the company noted “the positive impact of the large component replacement program” for the French fleet.
France had generated 381TWh up to November 2011. So France generated 40 TWh in December.
The capacity factor of Indias 20 operational nuclear reactors, adding up to an installed capacity of 4,780 MWe, is now projected to top 80 per cent in 2012-13. 80 percent capacity of 4780 MWe is 33 TWh. However an 11% increase over 2010 would take generation to about 23 TWh.
In 2006-07, the capacity factor was 64 per cent, but plummeted to 50 per cent in 2008-09. (The capacity factor is the ratio of the actual output to its output if operated at full potential.) It bounced back to 61 per cent in 2009-10 and increased further to 71 per cent in 2010-11. In the first nine months of this fiscal, it has reached 78 per cent.
India is up 11% over last year.
There was an increase of 30-40TWh in nuclear generation by China, India and the Ukraine. The variation depending upon what India actually generated.
