nuclear
power
contributes about 15% of the world’s electricity generation. presently, there are some 435
nuclear
reactors in 30 countries with an installed
power
generation capability of 370 gw. today there is a renaissance for new
nuclear
power
plants
with 30
plants
under construction and another 70 firmly planned. near-term challenges include prolonging the lifetime of existing
plants
, rebuilding the infrastructure for delivery of new
plants
, and demonstrating storage of highly radioactive waste including spent fuel on an industrial scale. the opportunities and challenges in a 20-50 years time-frame include the development of generation iv
plants
and the technology infrastructure that follows. this will also require political and international policy arrangements and agreements in order to provide the full benefits.
nuclear
fission energy will then in prac- tice become a sustainable energy source to be used also for other purposes than electricity production. looking beyond 50 years, fission energy will contrib- ute a large portion of the electric energy needed – now using also thorium as a fuel. hundreds of those
plants
being built or planned today will still be in op- eration. fusion
power
plants
may start to contribute, but probably only from demonstration

nuclear
power
provides slightly more than 14% of the electricity production in the world. the share is about 30% within the european union. out of the 439 reactors in commercial operation in the world, 198 are situated in europe (144 within the eu). europe is more dependent on
nuclear
energy than any other comparable area. figure 1 provides an overview of the location of the
