Subject:

Emergency Response Data System (ERDS) Changes Grand Gulf Nuclear Station (GGNS), Unit 1 Docket No. 50-416 License No. NPF-29

Dear Sir or Madam:

In accordance with the requirements of 10 CFR 50, Appendix E, Section VI.3, Entergy is submitting this letter to provide notification of changes to the Grand Gulf Nuclear Station Emergency Response Data System (ERDS) link software scheduled to be implemented on July 25, 2011. Notification is required 30 days prior to any hardware or software changes that could affect the transmission format or computer communication protocol to the ERDS.

These changes will involve a conversion from a dial-up modem-based system to a more reliable internet-based system using a plant information server and NRC-supplied virtual private network (VPN) appliance. The Nuclear Regulatory Commission (NRC) ERDS Resource Desk was notified of this change via email dated April 20, 2011.

During implementation of this change, the existing ERDS link will remain available and will not affect the plant's ability to activate the existing ERDS link, if required.

This letter contains no commitments. If you have questions, please contact Mr. Chris Lewis, Manager, Emergency Preparedness, at (601) 437-2166.

Sincerely CLP/RRJ cc:
