Accident Dose Assessments 




Nuclear engineer and long-time industry executive, Arnie Gundersen gives a talk on his calculations of the amount of radiation released during the accident at Three Mile Island.  Mr. Gundersen's calculations differ from those of the NRC's and official industry estimates.

Part 1:

The irony is that 30 years after the most infamous U.S. accident since the splitting of the atom, there is talk of a nuclear-power revival, driven by greenhouse-gas concerns.


A separate reality is that three decades after the iconic partial-meltdown at Three Mile Island, the nuclear plant's surviving Unit 1 reactor is almost assured of soon receiving government permission to continue operating through 2034.


Is that a good thing?

Mary Osborn Ouassiai still calls it home. Her house behind the WITF television station building in Swatara Township, Dauphin County, Pa., overlooks a valley that slopes down several miles toward the Susquehanna River. 

She can see the cooling  towers on Three Mile Island from her driveway; the same driveway she walked across on March 28, 1979 to put her 9-year-old daughter on the school bus. She looks out the same windows she looked out of that day, and the days following, holding her son, 2, and wondering if her family and neighbors were being told the truth about the danger to which they had been exposed. 




Nuclear Regulatory Commission staff will conduct an informational open house on Tuesday, March 31, regarding the agency’s annual assessment of safety performance for the Beaver Valley nuclear power plant.


The open house, which will take place from 6:30 to 8 p.m. at the Shippingport Community and Municipal Center, 164 State Road 3016 in Shippingport (Beaver County), Pa., will provide members of the public with an opportunity to learn first-hand from NRC staff members about performance at the plant during 2008. Unlike the standard meeting format, the setting will allow citizens to discuss plant-related topics on a one-on-one basis with NRC inspectors assigned to the plant and their NRC Region I supervisor.

I’d like to begin with a review of the status of nuclear power and nuclear regulation the day before the 

accident at Three Mile Island.  As of that time, the NRC’s licensing process, maligned though it often was, 

had issued more licenses than the next five nations combined, though half of the construction permit 

recipients did not complete their power plants.   



 Remember TMI, March 28, 2009: Thirty Years since the Atomic Accident


The NRC and the nuclear industry are attempting to revise the history of the Three Mile Island accident on March 28, 1979. They say no significant amount of radiation got out and nobody got sick or died. The nuclear industry's sophists-for-hire call TMI a nuclear industry success story.  Nothing is farther from the truth.

BRATTLEBORO If you've been keeping an eye on Vermont Yankee's decommissioning trust fund, it has had so many ups and downs in the past year you might need to take some anti-nausea medication.


In just the past year, the fund has lost $80 million, from $427 million in March 2008 to $347 million by the end of last month. Since September 2007, the fund has lost $93 million.

TMI Accident 30th Commemorative, March 28, 2009

Background: It will be 30 years ago on March 28 since the Three Mile Island nuclear power plant had a radioactive accident near Harrisburg, PA.There were no sirens in place to warn communities around the melting reactor. Instead, the warning came with early morning sightings of an iridescent cloud billowing out of the cooling tower, people downwind experiencing a metallic taste, sunburn-like symptoms and loss of hair. Birds fell in large numbers from the trees and the insects fell silent. X-ray film became mysteriously fogged in a local dentist's office vault. After two terrifying days, tens of thousands of area residents had spontaneously evacuated before then-Governor Thornburg advised pregnant women and young children within five miles of the reactor to leave the area.

The Nuclear Regulatory Commission staff has completed its final environmental impact statement (EIS) for the Susquehanna Steam Electric Station, Units 1 and 2, and concluded that there are no environmental impacts that would preclude license renewal for an additional 20 years of operation. The staff has also issued a safety evaluation report (SER) that documents the interim results of the NRC staff’s review of the license renewal application and site audits of Susquehanna’s aging management programs to address the safety of plant operations during the period of extended operations. Overall, the interim results show that PPL has identified actions that have been or will be taken to manage the effects of aging in the appropriate safety systems, structures and components of the plant and that their functions will be maintained during the period of extended operation.

Forget that 17 utilities have applied to build 30 new nuclear plants in the United States.


Forget that concerns over global warming have made even environmentalists cast an 

eye toward nuclear power.


Forget that a recent survey shows 55 percent of Americans now are behind more nukes.


No new nuclear plant has been built in the country since the accident at Three Mile Island

 — 30 years ago this month. 


The infamous accident and its once unthinkable partial meltdown of the reactor core brought

new construction of nuclear plants to a grinding halt.
