on wna, a world nuclear association, 2100 to? how can anybody guess how many nuclear power plants we will have then? typically, these studies look at gdp growth and they project what electricity demand will be and they assign a percentage of that to nuclear. as my statistics professor told me, there is no truth. you have to see when the concrete is being poured to see what these countries will do. >> about the world nuclear association tables, if you go on there website, they catalog the nuclear reactors as operational, under construction, planned, and proposed. you can project out operational out when the licenses run and when they sort of fade out of service. you run into the issue of license extensions. in the u.s., they go beyond 60 years. reactors under construction only represent about 10% of operational reactors. it is a 10% of addition and they are most likely to get built but may be delayed a few years. reactors that are planned typically are those where they have specific dates with respect to start of construction and
