Dear Sir or Madam:
In accordance with 10 CFR 50.46(a)(3)(ii) Grand Gulf Nuclear Station, Unit 1 (GGNS) is required to report to the Nuclear Regulatory Commission-(NRC), at least annually, the estimated effect on the limiting Emergency Core Cooling System (ECCS) analysis caused by changes to or errors discovered in the acceptable ECCS evaluation model.
Since the last 10 CFR 50.46(a)(3)(ii) report, dated. October 3, 2017 [see Reference 1],
through October 3, 2018,** there have been zero model changes and zero errors discovered in the GGNS ECCS evaluation model. The current Licensing Basis peak clad temperature (PCT) results in a projected current PCT < 1730 °F. This is below the 2200 °F acceptance criterion of 10 CFR. 50.46.
This letter contains no new Regulatory Commitments. Should you have any questions concerning the content of this letter, please contact Douglas Neve, Manager Regulatory Assurance at 601-437-2103.
