SUMMARY
OF USAR DELETIONS Description of Deletion Basis for Deletion Deleted reference in each section This discussion is obsolete information to a built-in check source for the that was not deleted at the time the Elevated Release Point (ERP),
station modification was implemented Rad waste/ Augmented Radwaste, to disconnect or remove the built-in and Turbine Building radiation check sources for the ERP, monitoring systems.
Rad waste/ Augmented Radwaste, and Turbine Building radiation monitoring systems.
Deleted specific spacing distance Discussion of the spacing distance of "approximately 250 foot between fire hydrants is excess detail intervals," between fire hydrants.
and was replaced with a description of "acceptable intervals." The current yard fire hydrant spacing was evaluated and determined functionally equivalent.
Deleted term "ionization."
The term ionization is excess detail and was deleted as other types of smoke detectors are used.

SUMMARY
OF REGULATORY COMMITMENT CHANGES The following regulatory commitment was revised by Nebraska Public Power District (NPPD) based upon evaluation performed in accordance with Nuclear Energy Institute 99-04, Revision 0, "Guidelines for Managing NRC Commitment Changes." This summary does not include any commitment changes for which separate U.S. Nuclear Regulatory Commission (NRC) notification was provided.

Description:
Letter from G.A. Trevors (NPPD) to NRC dated October 15, 1990, "Generic Letter 89-13 Recommended Inspection Program" In the subject response, NPPD stated that "The District will sample the Missouri River sediment once per year and analyze the samples for biological fouling organisms."
NPPD has withdrawn this commitment based on guidance in Recommended Program to Resolve Generic Issue 51 (Enclosure 1 of Generic Letter 89-13), paragraph D, which states in part "Water and substrate sampling is only necessary at freshwater plants that have not previously detected the presence of Asiatic clams in their source water bodies. If Asiatic clams are detected, utilities may discontinue this sampling activity if desired, and the chlorination ( or equally effective) treatment program should be modified to be in agreement with paragraph B."
The first Asiatic clam was identified at Cooper Nuclear Station (CNS) during a 2004 inspection of a Turbine Equipment Cooling heat exchanger and the first zebra mussel was identified in 2016 in a Circulating Water bay. NPPD has implemented a chemical treatment program for the Service Water/Circulating Water systems at CNS to control zebra mussel and Asiatic clam populations.
Chemical injections are controlled via maintenance plans and NPPD continues to perform routine sampling and analysis of the intake bays to monitor for biological fouling organisms.
Letter from R.L. Gardner (NPPD) to NRC dated August 6, 1993, "Licensee Event Report 93-029, Revision 0" In the subject correspondence, NPPD's corrective action reported in the Licensee Event Report (LER) was "Procedures related to ASME Class 1 N system leakage testing will be revised to require better coordination of activities in the vicinity of the High Pressure-Scram switches and sensing lines which could result in an RPS actuation."
NLS2021013 Page 2 of2 This commitment was revised to "Prevent unwanted RPV High Pressure scrams during the RPV Pressure test by defeating RPV High Pressure scram function during the ASME Class IN System Leakage test."
The LER was required due to an event involving a spurious Reactor Protection System scram signal during replacement of an excess flow check valve during the IN system leakage test. NPPD re-evaluated the evolution using recently acquired test equipment and further evaluated the Technical Specification Limiting Condition of Operation requirements for the Reactor Pressure Vessel (RPV) High Pressure Scram during the hydrostatic test.
It was determined a better solution was to defeat the RPV High Pressure Scram function during the test. This change does not impact the ability to perform any required safety function and is an improvement to the overall risk associated with the hydrostatic test.
