Subject:
Emergency Response Data System (ERDS) Changes River Bend Station - Unit 1 Docket No. 50-458 License No. NPF-47 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 River Bend Station Emergency Response Data System (ERDS) link software scheduled to be implemented on August 15, 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.
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 any questions, please contact Mr. Dean Burnett, Manager, Emergency Preparedness, at (225) 378-3310.
