Nuclear realities

The world’s first nuclear pow­er sta­tion, at Ship­ping­port, Pa., came on line in the late 1950s. After the hor­rors of Hiroshi­ma and Nagasa­ki, the Ship­ping­port plant seemed to vin­di­cate our hard-won knowl­edge of the atom­’s secrets. Here at last was a peace­time use for atom­ic ener­gy. Mag­a­zines were full of arti­cles with titles like “The Atom: Our Obe­di­ent Ser­vant.” For most of us, it was the dawn­ing of an age bright with promise.
