SUBJECT:
Emergency Response Data System (EROS) Changes Grand Gulf Nuclear Station, 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.a, Entergy is submitting this letter to provide notification of changes to the Grand Gulf Nuclear Station Emergency Response Data System (EROS) link software implemented on March 1,2012. Any hardware and software changes that affect the transmitted data points identified in the EROS Data Point Library (DPL) must be submitted to the NRC within 30 days after the changes are completed.
These changes will involve a deletion of four EROS data points and a modification of four data points, requiring a Data Point Library (DPL) change.
This letter contains no commitments. If you have questions, please contact Mr. Chris Lewis, Manager, Emergency Preparedness, at (601) 437-2166.
Sincerely, Attachment 1: EROS Data Point Change Package cc: (See Next Page)
