Globally, the TC/PL values remain stable for most of the OECD countries. However, in some countries the trend is decreasing. In Korea, the total capacity increased considerably at the end of the 1990s (because of its considerable nuclear programme), but the high economic growth rate led to considerable electricity consumption, resulting in an important decrease of TC/PL in 2000-2007. The electricity generated by nuclear is only slightly sensitive to the variations of the price of uranium, contrary to energy sources burning fossil fuel.
