Power Reactor Development Co. v. International Union of Electrical, Radio & MacHine Workers
Headline: Decision allows a nuclear developer to build a fast-breeder reactor without a final safety finding, upholding the Atomic Energy Commission’s provisional construction-permit practice and letting companies begin construction before full operating approval.
Holding: The Court held that the Atomic Energy Commission may issue a provisional construction permit based on tentative safety information about the general reactor type and may defer the definitive safety-of-operation finding until the operating-license stage.
- Allows reactor developers to start construction before a final safety finding.
- Keeps final, detailed safety approval for the later operating-license stage.
- Affirms AEC rules that let provisional permits be issued with incomplete technical data.
Summary
Background
A private company called Power Reactor Development Company wanted to build a new fast-neutron breeder reactor at Lagoona Beach, Michigan, near Detroit and Toledo. The Atomic Energy Commission issued a provisional construction permit in 1956 that let the company build but not operate the reactor. Several labor unions intervened and challenged continuation of that permit after extensive hearings and reports, arguing the Commission had not made the full safety finding required for operation.
Reasoning
The Court examined the Atomic Energy Act and the AEC’s rule 50.35 to decide whether the agency must make the same definitive safety finding before construction that it must make before operation. The majority held that the regulation reasonably allows a preliminary finding based on incomplete information about the general type of reactor, while reserving the definitive safety finding for the later operating-license stage. The Court gave weight to the agency’s expertise, its step-by-step licensing practice, and evidence that Congress and its Joint Committee knew of and did not change that practice. The Court reversed the Court of Appeals and upheld the AEC’s action.
Real world impact
As a practical matter, reactor builders can begin construction under provisional permits while final safety data and a full hazards report are completed later. The decision does not eliminate later safety checks: a full hazards report, investigations by the Advisory Committee on Reactor Safeguards, public hearings, and a definitive operating-license decision are still required, and operation may be limited by stepwise power increases and additional hearings.
Dissents or concurrances
Justice Douglas (joined by Justice Black) dissented, arguing the statute and legislative history require a safety finding before any construction permit is issued and warning that permitting construction first creates pressure to approve operation later.
