This is the second in a series of commentaries about the vital role nuclear safety inspections conducted by the Nuclear Regulatory Commission (NRC) play in protecting the public. The initial commentary described how NRC inspectors discovered that limits on the maximum allowable control room air temperature at the Columbia Generating Station in Washington had been improperly relaxed by the plant’s owner. This commentary describes a more recent finding by NRC inspectors about an improper safety assessment of a leaking cooling water system pipe on Entergy’s Unit 3 reactor at Indian Point outside New York City.

The Nuclear Regulatory Commission (NRC) adopted its Reactor Oversight Process (ROP) in 2000. The ROP is far superior to the oversight processes previously employed by the NRC. Among its many virtues, the NRC treats the ROP as a work in progress, meaning that agency routinely re-assesses the ROP and makes necessary adjustments.
Earlier this year, the NRC initiated a formal review of its engineering inspections with the goal of making them more efficient and more effective. During a public meeting on October 11, 2017, the NRC working group conducting the review outlined some changes to the engineering inspections that would essentially cover the same ground but with an estimated 8 to 15 percent reduction in person-hours (the engineering inspections and suggested revisions are listed on slide 7 of the NRC’s presentation). Basically, the NRC working group suggested repackaging the inspections so as to be able to examine the same number of items, but in fewer inspection trips.
The nuclear industry sees a different way to accomplish the efficiency and effectiveness gains sought by the NRC’s review effort—they propose to eliminate the NRC’s engineering inspections and replace them with self-assessments. The industry would mail the results from the self-assessments to the NRC for their reading pleasure. Read more >
