core memories

WRITTEN BY Maria V. Snyder

Three Mile Island. TMI. THE NAME EVOKES AN AUTOMATIC association with the most serious nuclear power plant accident in the United States. Even 30 years later, memories of those living in Central Pennsylvania during the accident are still vivid.

The accident began in TMI-2’s plant on Wednesday, March 28, 1979, at about 4 a.m. The main feedwater pumps stopped running and prevented the steam generators from cooling down. Both the reactor and steam turbines automatically shut off, which increased the pressure in the system. In order to fix the problem, a relief valve opened to decrease the water pressure, but once the pressure decreased, the valve failed to close. Cooling water therefore poured from the open valve instead of going into the reactor core.

charge, and he was calm and didn’t flowercoat anything.” The accident had caught everyone offguard. Since then, the NRC and other government organizations have made major changes to policy and procedures. Yet public fear and distrust remain, and the incident has halted and slowed nuclear plant construction throughout the United States, thereby “killing the nuclear industry for 30 years,” Andrew Kadak, MIT professor of nuclear engineering, said. Only 35 new commercial reactors have been put online since 1979. Cleanup of TMI-2 lasted 12 years and cost $973 million. Currently, the reactor is in long-term monitored storage. TMI-1 reactor was restarted in October 1985, and has a license to operate until 2014. In January 2008, a license renewal application, which would allow TMI-1 to operate until 2034, was submitted to the NRC. Memories of fear and panic will remain with those who lived through those five days in 1979. Everyone would likely agree with Dick Morgan, who says, “It’s an experience I don’t want to go through again.” ) ) )
