After months of preparation and planning, the Tennessee Valley Authority last month gave the go-ahead to allow inspectors with the U.S. Nuclear Regulatory Commission to begin intensive inspections at Browns Ferry Nuclear Plant.
The inspections mark the third and final part of the stringent 95003 inspections ordered by the NRC. The inspections were in response to a red finding issued when a Unit 1 low-pressure coolant injection valve, also used for shutdown cooling, failed to open during a refueling outage in October 2010.
TVA informed the NRC in writing on Feb. 15 that the agency could proceed with the inspections. The first phase of inspections were completed in October 2011, and the second phase in January 2012.
Since the completion of the second phase, TVA developed a “comprehensive Integrated Improvement Plan designed to address problem areas at the site,” said TVA spokesman Mike Bradley.
