Facts

After Yankee Atomic Electric Company permanently ceased operations at Yankee NPS and obtained a possession-only license, it sought to begin an early component removal project before submitting or obtaining approval of a decommissioning plan. The project involved removing and shipping major radioactive components and would permanently dispose of about 90% of the plant's nonfuel residual radioactivity before any decommissioning plan approval or environmental review. For several years, NRC policy had stated that major structural changes required prior NRC approval, but in 1993 the Commission issued staff requirements memoranda reversing that position without explanation and allowed such activities if certain conditions were met. CAN repeatedly requested hearings and objected that the NRC was violating its regulations and permitting decommissioning without prior environmental review, but the NRC denied relief.

Issue

Whether the NRC acted unlawfully by changing its decommissioning policy without explanation, by allowing extensive decommissioning before conducting NEPA review, and by denying CAN a hearing under AEA § 189(a). Also, whether CAN established a Fifth Amendment takings or due process violation.

Rule

An agency may change its interpretation of its regulations, but a significant departure from settled policy must be accompanied by a reasoned analysis showing the shift is rational; otherwise the change is arbitrary and capricious. Under AEA § 189(a), affected persons are entitled to a hearing in proceedings for modification of rules and regulations dealing with licensee activities, and the substance of NRC action controls, so an action that effectively enlarges an existing licensee's authority is a de facto license amendment requiring a hearing. NRC action that effectively permits decommissioning, including approval of funding or advice allowing the work to proceed, cannot be treated as mere oversight to evade NEPA review.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

For six years, the Federal Reactor Safety Board publicly interpreted its regulations to require prior agency approval before a shuttered reactor's owner could remove large irradiated turbines. In 2026, the Board issued an internal memorandum saying such removals could proceed without prior approval if staff saw no immediate safety problem, but the memorandum offered no facts, legal analysis, or changed circumstances. Residents of Toledo, Ohio sought review after the Board denied them a hearing.

If a court applies the majority's reasoning, which is the strongest basis for setting aside the Board's new policy?

Explanation. The majority held that an agency may change its interpretation, but when it significantly departs from settled precedent or interpretive policy, it must confront the change and give a reasoned analysis showing the shift is rational. An unexplained reversal is arbitrary and capricious. The opinion did not say agencies can never change course, nor that formal rulemaking is always required, nor that invalidity depends on proving the prior interpretation was the only possible one.
