The plant was built near a geological fault in the Columbia River in the 1970s. In 1989, the Nuclear Regulatory Commission fined PGE for debris in two sumps that could have prevented its emergency core-cooling system from working in a disaster.
Its ongoing problems led many to believe that it was the inspiration for the error-ridden nuclear plant in the TV show ``The Simpsons,'' a creation of Portland-born Matt Groening. (Groening's representative said it is not.)
The plant rarely ran at full capacity, often stopping operations when there was a major snowmelt because PGE could buy excess hydroelectric power from nearby Bonneville Dam cheaper than the power plant could make it. And the market for energy was changing, making Trojan's operation more labor intensive and expensive than other alternatives.
So after steam tubes cracked and leaked radioactive gas into the air, PGE and regulators decided it made more financial sense to close the plant than to continue operations. Built for $460 million, Trojan was approved to be decommissioned at a $429 million total cost.
