IMPROVEMENTS
Future Of Atomic Energy For Peaceful Purposes
By TOM MARGERISON
BRITAIN'S plans for using atomic energy to
generate a quarter of her total requirements of electricity by 1975 are now for advanced. The first atomic power station at Calder Hall on England's north-west coast has been at work for several months. Detalled plans for three other atomic power stations, each twice the size of Calder Hall, have already been announced. Announcement of a fourth is expected soon.
These four improved versions timbiné dich tinted the electrielly of Calder Hall, show quite generator. All the problems clearly that for some years to revolve around the dévign of come this type of atomic power the atomic furnace or nuclear station will be unrivalled where renelor.
