Overview
The Trojan Nuclear Power Plant was a pressurized water reactor (PWR) facility located in the northwest United States, specifically in the state of Oregon. It holds the distinction of being the sole commercial nuclear power plant ever constructed in Oregon. The plant was operated by Portland General Electric and had an installed capacity of 1130 MW. Commissioned in 1976, the facility is now classified as decommissioned. The plant was situated 30 miles north of Portland, Oregon, and southeast of the town of Rainier, Oregon. Its location placed it on the banks of the Columbia River, a key geographic feature for the region’s energy infrastructure.
Public opposition to the Trojan Nuclear Power Plant was a defining characteristic of its operational history, beginning from the earliest stages of its design. This resistance was not a singular movement but was organized into three primary groups: the Trojan Decommissioning Alliance, Forelaws on the Board, and Mothers for Peace. These organizations coordinated efforts to challenge the plant’s development and ongoing operation. The protests were largely non-violent in nature, though they persisted throughout the plant’s active years. Starting in 1977, the demonstrations led to numerous arrests of participants, highlighting the intensity of the local and regional debate surrounding nuclear energy in the Pacific Northwest. The sustained public scrutiny and organized dissent contributed to the complex socio-political environment in which the plant operated until its eventual closure.

Its presence in the northwest United States offered a baseload power source that complemented the variable nature of hydroelectric output, providing stability to the grid. However, the plant's singular status in the state also meant that its performance and public perception had an outsized influence on Oregon's broader energy policy and future nuclear ambitions.
Public Opposition and Legacy
From its design stage onward, the Trojan Nuclear Power Plant faced considerable public opposition. Three main groups led the resistance: the Trojan Decommissioning Alliance, Forelaws on the Board, and Mothers for Peace. These organizations coordinated largely non-violent protests starting in 1977, which resulted in the subsequent arrests of participants. This sustained public engagement reflected broader societal debates about nuclear safety, waste management, and the environmental impact of energy infrastructure. The intensity of the opposition in Oregon contrasts with the more widespread acceptance seen in other nuclear-heavy states, contributing to the decision to decommission the plant rather than expand its footprint. The legacy of these protests continues to influence public discourse on energy projects in the Pacific Northwest.
Unique Decommissioning Method
The decommissioning of the Trojan Nuclear Power Plant introduced a novel approach to nuclear waste management. It was the first commercial nuclear facility to utilize the method of burying the whole reactor vessel. This technique involved placing the entire reactor pressure vessel, along with its internal components, into a specially designed concrete sarcophagus and interring it in a shallow underground vault. This method offered a cost-effective alternative to the more traditional approach of cutting the reactor into smaller pieces for transport and storage. The success of this unique decommissioning strategy has provided valuable insights for the nuclear industry, influencing how other facilities consider the disposal of large, bulky nuclear components. As the sole commercial nuclear plant in Oregon, its decommissioning marked the end of an era for state nuclear power, leaving a lasting technical and historical imprint on the region's energy landscape.
