theNuclear Regulatory Commission (NRC) issued "River Bend Station -

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

Entergy concurswith the violation ascitedinthe Notice (NOV) ofViolation regarding Technical Specification 5.4.1.a forfailure to maintain procedures required byRegulatory Guide 1.33, Revision 2,Appendix A.Specifically, the NRCissued aviolation forfailuretomaintain adequate procedures for feedwater system operation onApril 29,2020, andthe licensee failed torestore within compliance a reasonable amount of time.

Inaccordance with 10CFR2.201, this enclosure provides Entergy'sreply totheNotice of Violation.

M During anNRCinspection conducted from January 25through February 12,2021, a violationof NRCrequirements wasidentified. Inaccordance with the NRCEnforcement Policy, theviolation islisted below:

Technical Specification 5.4.1.a, requires, inpart, thatprocedures shall beestablished, implemented, andmaintained covering theapplicable procedures recommended in Appendix A ofRegulatory Guide 1.33, Revision 2.Section 4.oofAppendix A to Regulatory Guide 1.33, Revision 2,requires instructions fortheoperation of the feedwater system.

Contrarytotheabove, from June1,2019, toFebruary 10,2021,thelicensee failed to establish,implement, and maintain applicable procedures recommended inAppendix A ofRegulatory Guide Revision 1 .33, 2, Section 4.o fortheoperation ofthe feedwater system. Specifically, thelicensee established Procedures SOP-0009, "Reactor Feedwater System (SYS #107)," Revision 80 82,andOSP-0053, "Emergency and Transient Response Support Procedure," Revision 27and28,tomeet theRegulatory Guide 1.33 requirement, andthe licensee failed tomaintainthese procedures for feedwater operation toinclude necessary precautions toprevent operation ofthesystem inanimproper lineup.

This violation isassociated with a Green SDPfinding.

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

IntegratedInspection Report 05000458/2020001." Theinspection report documented a non-citedviolation (NCV 2020001-

03) for failure to maintain adequate procedures forf eedwater system operation because ofthe inspectors review ofa reactor scram that occurred onMay31,2019. Additional details were

RBG-48084 Enclosure Page 2of2 provided intheinspectionreport thattheNRCconcerns werespecific toSOP-0009, "Reactor Feedwater System," andOSP-0053, "Emergency andTransient Response Support Procedure."

Although the violation was documented initially inthe Corrective Action Program (CR-RBS-2020-00965) the condition report wasclosed tothetwoactions taken under CR-RBS-2019-03891 that addressed the causal evaluation forthereactor scram. All corrective actions were closed to NRC issuing inspection priorthe report05000458/2020001.

Uponreceipt oftheinspection report, RegulatoryAssurance personnel didnotrecognize that a newcondition report needed to begenerated toensure theadditional details associated with the NCVwereadequately addressed asrequired byEntergy procedure EN-Ll-123, "NRCInspection Support." Asa result correctiveactions werenot developed 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 were taken:

Action 1: Revised OSP-0053, Emergency andTransient Response Support Procedure, hard card toensure Operators understand therequirements that atleast one LowPressure Heater Stringisinservice whenrestarting feedwater pumps.

Action 2: Revised SOP-0009, Reactor Feedwater System, toadd a precaution and limitation statement tonot attempt tostart a Reactor FeedPump unless at least oneLowPressure Heaterstring isvalved into service on the condensate side.

Asa result ofthe corrective actions taken, Entergycompleted the required changes tothe affected procedures, addressing therefore, the issueof concern and resulted in restoringfull compliance.

M Noadditional corrective actions havebeenidentified.

Entergy restored fullcompliance onFebruary 10,2021
