A class-action lawsuit, Walburn et al. v. Centrus Energy Corp. et al., filed in September 2020, brought to light extensive allegations of a decades-long pattern of corruption, dosimetry manipulation, and environmental contamination at the Portsmouth Gaseous Diffusion Plant (PORTS) in Piketon, Ohio. While this specific lawsuit was voluntarily dismissed by the plaintiffs on November 11, 2021, and officially terminated on November 17, 2021, its allegations remain a critical part of the historical record regarding PORTS and the broader challenges of accountability in the nuclear industry. The lawsuit claimed that plant operators, including the United States Department of Energy (USDOE) and various contractors, engaged in a "Nuclear Fraud Enterprise" to conceal the true extent of radiation exposure to workers and the surrounding communities, prioritizing profit and operational goals over public safety.
