Subject:
Annual Report of Changes and Errors in Emergency Core Cooling System Evaluation Models for 2021 Cooper Nuclear Station, Docket No. 50-298, DPR-46
Reference:
Letter from Linda Dewhirst, Nebraska Public Power District, to U.S. Nuclear Regulatory Commission, dated January 20, 2021, "Annual Report of Changes and Errors in Emergency Core Cooling System Evaluation Models for 2020"
Dear Sir or Madam:
The purpose of this letter is to submit the 2021 annual report of changes and errors in the Emergency Core Cooling System (ECCS) evaluation models pursuant to 10 CFR 50.46(a)(3)(ii) for Cooper Nuclear Station (CNS).
Per the reference letter, Nebraska Public Power District previously reported errors/changes in the ECCS evaluation models for GNF2 fuel, these errors continued to apply to the ECCS evaluation methodologies for 2021. There were two zero-degree errors for the GNF2 fuel type reported in*
2021 applicable to the licensing basis peak clad temperature (PCT). CNS continues to comply with the PCT limit of 2200°F specified in 10 CFR 50.46(b)(1 ). to this letter itemizes the changes/errors in the ECCS evaluation models that remained applicable in 2021 and Attachment 2 provides data that demonstrates compliance with the ECCS performance requirements of 10 CFR 50.46.
This letter makes no regulatory commitments.
If you have any questions regarding this report, please contact Ryan VanderPlas, Engineer, at (402~~5-5409. /// ___
