Dear Mr. Edington:

The Commission has issued the enclosed Amendment No. 186 to Renewed Facility Operating License No. NPF-41, Amendment No. 186 to Renewed Facility Operating License No. NPF-51, and Amendment No. 186 to Renewed Facility Operating License No. NPF-74 for the Palo Verde Nuclear Generating Station (PVNGS), Units 1, 2, and 3, respectively. The amendments consist of changes to the Updated Final Safety Analysis Report (UFSAR) in response to your application dated July 22, 2010, as supplemented by letter dated April 8, 2011.

The amendment revises an element of the methodology used in evaluating the radiological consequences of design basis steam generator tube rupture (SGTR) accidents. Specifically, the changes will revise the PVNGS Updated Final Safety Analysis Report (UFSAR) Section 15.6.6, "Steam Generator Tube Rupture," to reflect a lower iodine spiking factor assumed for the coincident event Generated Iodine Spike (GIS) and the resulting reduction in the radiological consequences for the Limiting SGTRLOPSF [Steam Generator Tube Rupture with Loss of Offsite Power and Single Failure] Event."
