V. A look ahead: More plants to come; Computer's role on rise

In the U.S., there are 73 commercial nuclear reactors in operation. Eighty-three more are in various stages of construction, and construction permits are being sought for 12 others. The numbers are essentially the same as before the TMI accident, though a few plants have been canceled, and chances are good that nearly all of the proposed plants will eventually be licensed to operate.
