theNuclear Regulatory Commission (NRC)issued "RiverBendStation

- Biennial Problem Identification andResolution Inspection Report 05000458/2021010 andNotice ofViolation" (ADAMS Accession Number ML21064A220).

Entergy concurs with the violation ascitedintheNotice ofViolation (NOV) regarding Technical Specification 5.4.1.a for failure to maintain procedures required byRegulatory Guide 1.33, Revision 2,Appendix A.Specifically, the NRCissued aviolation forfailure tomaintain adequate procedures for feedwater system operation onApril 29,2020,andthelicensee failed torestore compliance within areasonable amount oftime.

Inaccordance with10CFR2.201, this enclosure provides Entergy's reply totheNotice of Violation.

M During anNRCinspection conducted fromJanuary 25through February 12,2021,aviolation of NRCrequirements wasidentified.

Inaccordance with theNRCEnforcement

Contrary totheabove, fromJune1,2019,toFebruary 10,2021,thelicensee failed to establish, implement, andmaintain applicable procedures recommended inAppendix A

ofRegulatory Guide1.33, Revision 2,Section 4.ofortheoperation ofthefeedwater system.

Specifically, thelicensee established Procedures SOP-0009, "Reactor Feedwater System(SYS

1. 107),"

Revision 80

- 82,andOSP-0053, "Emergency and Transient

Response

Support Procedure,"

Revision 27and28,tomeettheRegulatory Guide1.33requirement, andthelicensee failed tomaintain these procedures for feedwater operation toinclude necessary precautions toprevent operation ofthesystem inanimproper lineup.

Thisviolation isassociated with aGreenSDPfinding.

Reason.for..the Violatio.n OnApril 29,2020theNRCissued "River BendStation

- Integrated Inspection Report 05000458/2020001."

Theinspection report documented anon-cited violation (NCV 2020001-03) forfailure tomaintain adequate procedures forfeedwater system operation because ofthe inspectors review ofareactor scramthat occurred onMay31,2019.Additional details were

RBG-48084 Enclosure Page 2of2 provided intheinspectionreport that theNRCconcerns werespecific toSOP-0009, "Reactor Feedwater System,"

andOSP-0053, "Emergency andTransient

Response

Although the violation wasdocumentedinitially intheCorrective Action Program (CR-RBS-2020-00965) the condition report wasclosed tothetwoactions taken underCR-RBS-2019-03891that addressed thecausalevaluation forthereactor scram.

Allcorrective actions were closed prior tothe NRC issuing inspectionreport 05000458/2020001.

Uponreceipt oftheinspection

report, RegulatoryAssurance personnel didnotrecognize that a

newcondition report needed to begenerated toensure theadditional details associated withthe NCVwereadequately addressed asrequired byEntergy procedure EN-Ll-123, "NRCInspection Support."

Asaresult correctiveactions werenotdeveloped inaccordance with EN-LI-102, "Corrective Action Program,"

toadequately address correcting theSOP-0009 andOSP-0053 procedures.

Theidentified condition wasentered into Entergy'scorrective action program (CR-RBS-2021-00644).

Thefollowing corrective actions weretaken:
