C-10 Submits Comments on NextEra License Amendment Request

March 9, 2017 – Members of the C-10 Foundation board of directors submitted comments to the U.S. Nuclear Regulatory Commission relative to NextEra Energy Seabrook LLC’s License Amendment Request (LAR) 16-30. In the LAR, NextEra Energy Seabrook, LLC  seeks to “Revise Current Licensing Basis to Adopt a Methodology for the Analysis of Seismic Category I Structures with Concrete Affected by Alkali-Silica Reaction.”

This docket pertains to the calculations of the concrete’s ability to bear load and withstand a seismic event such as an earthquake.  But in C-10’s view, this LAR is a paper solution. The thousands of tiny cracks and larger ones in the power plant’s concrete dome and retaining walls remain, and the concrete continues to degrade. As noted in our comments, experts have studied this issue, and there is no known solution or remedy. More information on the proceeding is here.  Read our comments.
