NRC: Columbia Generating Station returned to baseline oversight after 2024 radiation-protection issues
Summary
Nuclear Regulatory Commission resident inspectors told the Richland City Council on May 6 that Columbia Generating Station has been returned to the Reactor Oversight Program's baseline column after resolving white-significance findings from 2024; NRC said inspections found mostly low-risk issues and the plant remains operating safely.
The Nuclear Regulatory Commission told the Richland City Council on May 6 that Columbia Generating Station has been returned to the oversight program's baseline level after addressing performance issues identified in 2024.
The NRC's on-site team described the agency's reactor oversight process, the color-coded performance indicators and the follow-up inspections that led to the change. "We completed the items they had to work through and were satisfied with their response," said Chris Hile, senior resident inspector, referring to corrective work that moved the plant from the NRC's regulatory-response column back to the licensing-response (baseline) column in April 2025.
The NRC resident inspectors emphasized that baseline status reflects the agency's continued oversight rather than the absence of any inspection activity. "Resident inspectors are the on-site everyday presence at nuclear power plants," Jason (resident inspector) said, describing the NRC's long-term inspections and continuous assessments of training, maintenance and safety barriers.
Why it matters: Columbia Generating Station is a major regional energy source; NRC oversight and any changes in enforcement level affect local emergency planning, worker safety and environmental monitoring. Trisha Vosper, branch chief for Region 4 in Arlington, Texas, told the council that the 2024 findings were rated white (low-to-moderate safety significance) and that inspection follow-up showed the licensee had adequately addressed root causes.
Details from the NRC presentation: - Columbia moved from the NRC's regulatory response column to the licensing-response (baseline) column on April 2, 2025, after corrective work and follow-up inspection. - Inspectors logged 6,791 hours of inspection-related activity at the site in 2024. - The plant had six "green" performance indicators in 2024 and two white findings that were corrected and closed in 2025, the NRC said. - The NRC plans a safety-conscious work environment inspection (referred to as a "93-01" inspection) at the plant in July 2025.
The NRC speakers also explained the agency's enforcement scale (green, white, yellow, red) and how those designations drive additional oversight when problems are identified. "We use a risk-informed process to grade issues," Vosper said, adding that the NRC's role is independent regulation focused on safety rather than advocacy for nuclear technology.
Council members asked no substantive follow-up questions during the public presentation. NRC staff made pamphlets and contact cards available after the presentation.
