If the Three Mile Island atomic reactor near Harrisburg hadn’t melted down 30 years ago this Saturday…well, there probably would have been an accident somewhere else. The entire U.S. nuclear industry was melting down in the 1970s, irradiated by spectacular cost overruns, interminable delays and public outrage. Forbes later called its collapse “the largest managerial disaster in business history, a disaster on a monumental scale.”
The TMI fiasco was a scary cultural moment, coming just two weeks after the release of the movie The China Syndrome, but there was nothing particularly tragic about it. It didn’t kill people. It didn’t kill nuclear power, which still provides 20% of U.S. electricity. It didn’t even kill TMI; the plant’s surviving reactor is about to receive a 20-year extension of its operating license. If anything, the core meltdown did some good, prompting desperately needed upgrades of nuclear safety standards.
No, the real tragedy was the dysfunction of the fledgling U.S. nuclear industry, which was already canceling new reactors all over the country before TMI, and has not ordered one since. That’s a shame, because nuclear reactors produce no carbon emissions. If we got 80% of our electricity from nukes today, as France does, we’d emit nearly a third less carbon. It would be the greenhouse-gas equivalent of taking all our cars off the road. So it would be nice if we could turn back the clock.
The other tragedy is that we can’t. There’s huge hype these days about a “nuclear renaissance,” since the industry now has its act together, fossil fuels are frying the planet, and solar and wind are only intermittent electricity sources. But nuclear energy is still paying the price for the disastrous era that ended with TMI. And it’s too high a price.
