Subject:
Emergency Response Data System (ERDS) Changes Waterford Steam Electric Station, Unit 3 (Waterford 3)
Docket No. 50-382 License No. NPF-38
Dear Mr. Collins:
In accordance with the requirements of 10 CFR 50, Appendix E, Section Vl.3, Entergy Operations, Inc (EOI) is submitting this letter to provide notification of changes to Waterford 3 emergency response data system (ERDS) link software scheduled to be implemented in September, 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 plants ability to activate the existing ERDS link, if required.
This letter contains no new commitments and no revisions to existing commitments.
If you have any questions or concerns, please contact William J. Steelman, Licensing Manager, at (504) 739-6685.
Sincerely, 4
