SUPPLEMENTARY INFORMATION:

The NRC has granted the request of SNC (the licensee) to withdraw its December 9, 2016, application (ADAMS Accession No. ML16344A411) for proposed amendment and exemption to COL NPF-91 and NPF-92 for the Vogtle Electric Generating Plant Units 3 and 4, respectively, located in Burke County, Georgia.

The proposed amendment would have changed plant-specific Tier 1 (and COL Appendix C) Tables 2.7.5-1, 2.7.5-2, and 2.7.7-3 and associated Updated Final Safety Analysis Report text, tables, and figures related to: (1) Modifying the configuration of the containment recirculation fan coil unit assemblies of the VCS, and revising the values for the various design parameters affected by this re-configuration, (2) adding a fourth pressure differential indicator to the radiologically controlled area ventilation system to be located in the auxiliary building component cooling system valve room, and (3) reducing the total ventilation flow provided through the VAS fuel handling area ventilation subsystem as a result of a reduction in heat loads in the areas serviced by the VAS.

This proposed amendment request was noticed in the Federal Register (82 FR 13662) dated March 14, 2017.
