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.

We have an excellent stone fireplace in the living room of the hill house, and often during the winter months I used to build a fire in it at suppertime; we ate while sitting on the couch. Jane and I really enjoyed all of the deep implications conjured up by the wood fires. We had the fireplace cleaned a couple of years ago, however, and with that break in routine I gave up using it: By then my time had become so taken up each day with what seemed like an endless list of things to do—with trying to help Jane, with working, with running the house, with answering the mail and so forth—that I just stopped making fires.

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.
