Ever since the accident to the nuclear reactor of Unit No. 2 at TMI, 31 months ago, the reactor’s great containment building and an auxiliary structure have been flooded with highly radioactive water. [It grew to be over eight and a half feet deep in the reactor building.] Utility engineers now have in operation a filtering system to decontaminate before storage the nearly one million gallons of water in the two buildings. The job is to take around nine months; the processed water will finally be disposed of in 1983; the filters holding the radioactive material will be trucked to facilities in Idaho and Washington State for testing and storage. Yet to come are the removal of the reactor’s cover, its damaged core, and the decontamination of the buildings themselves.

2. The cleanup costs at Three Mile Island are now projected at more than $1.5 billion, and will continue to increase. Many government officials and private analysts now believe that if the operating risks associated with nuclear power generating plants do not ultimately shut down many of them, their economic dilemmas will. I don’t know whether the nuclear power industry in the United States will die, but it’s in great trouble: Various studies show that around half of the 90 reactors under construction could be replaced by more economical coal-fired plants, containing excellent pollution-control equipment. By the late 1980s power from those new nuclear plants will be 25 percent more expensive than it would be if generated from coal.
There are plenty of more immediate challenges. For example: The staff of the Nuclear Regulatory Commission has asked the operators of more than 40 nuclear plants to check for cracks in the walls of the vessels encasing their pressurized-water reactors (which are the kind installed at TMI). Evidence is accumulating that the vessels are becoming embrittled by neutron radiation from the reactors much more quickly than their designers had anticipated. Small cracks have been found, but not all areas are reachable for testing. A rupture of a typical pressure vessel could result in an uncontrollable release of radiation into a containment building not designed to handle such a situation. If the building itself was breached, the escaping radiation could cause some 48,000 deaths, 250,000 nonfatal cancers and injuries, 5,000 first-generation birth defects, render 200 square miles uninhabitable, require decontamination of another 3,200 square miles, and damage other properties worth many billions of dollars. No protection against that kind of accident has ever been required by the NRC. The forces of consciousness at work would seem to be incredible—beyond our grasp.
