The Trojan Large Component Removal Project

摘要

On November 1, 1995, Portland General Electric (PGE) Company completed the Large Component Removal (LCR) Project, which represented the first phase of decommissioning the Trojan Nuclear Plant. This project entailed removing the four steam generators and pressurizer from the Containment Building, preparing them as their own shipping containers, and transporting them via barge and overland transporter to the U.S. Ecology low-level radioactive waste facility on the Hanford Reservation near Richland, Washington. The project had been in the planning stage since the plant was permanently closed on January 4, 1993. Even greater regulatory oversight than normal at a nuclear facility was involved because 1) the project was performed prior to the Decommissioning Plan being approved by the Nuclear Regulatory Commission (NRC), 2) the existing regulations did not apply directly to the shipments, and 3) water and land transport were involved. Finally, court actions in response to cases brought by Trojan as well as Yankee Rowe opponents had to be dealt with during implementation of the project.
