River Bend Station, Unit 1, License Renewal Operating Experience Audit Report I. Introduction On October 2 through 13, 2017, the U.S. Nuclear Regulatory Commission (NRC) Division of Materials and License Renewal (DMLR) performed an audit of Entergy Louisiana, LLC and Entergy Operations, Inc. (EOI) (the applicant), River Bend Station, Unit 1 (RBS), as part of the NRC staffs review of the RBS license renewal application (LRA) at a facility located in Rockville, Maryland. The purpose of the audit was for the NRC staff to perform an independent review of plant specific operating experience (OE) to identify examples of age related degradation, as documented in the applicants corrective action program database. The regulatory bases for the audit was Title 10 of the Code of Federal Regulations, Part 54 (10 CFR Part 54), Requirements for Renewal of Operating Licenses for Nuclear Power Plants,. The staff also considered the guidance contained in NUREG-1800, Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants, Revision 2 (SRP-LR) and NUREG- 1801, Rev. 2, Generic Aging Lessons Learned (GALL) Report, dated December 2010.

II. Background The NRC staff performed the review to identify pertinent examples of OE, concerning age related degradation, as documented in the applicants corrective action program database. The identified OE examples will be evaluated during the staffs subsequent technical review and auditing of aging management programs (AMPs), time limited aging analyses (TLAAs) and aging management review (AMR) line items. The staffs identification and evaluation of pertinent OE and additional related documentation, provides a basis for the staffs conclusions on the ability of the applicants proposed AMPs and TLAAs to manage the effects of aging in the period of extended operation.

III. Audit Activities The following sections discuss the areas reviewed by the staff and identified examples of pertinent OE.

CR-RBS-2009-0694 FPW-V164 juncture and piping is greatly 02/09/2009 corroded. The piping downstream of where the valve joins the pipe is visibly pitted by the corrosion. The floor underneath the valve is rust stained.

CR-RBS-2009-2516 During execution of WO 183858 it was noted that 02/09/2009 both runs of vertical piping had extensive corrosion where the pipe nipples were screwed into the valves. On close examination, the piping is leaking because the threads are deteriorated from the inside.

CR-RBS-2010-0160 During inspection of FPW-STR6A the inlet piping 0/12/2010 at the strainer has a large amount of rust build up on the pipe. There are rust corrosion spots inside pipe, about the size of a silver dollar. The pipe has a restriction of flow but it is not totally plugged.

CR-RBS-2010-1240 A corrosion spot was detected the on piping tee 03/18/2010 to FPW-P2. A pre-inspection walk down of the area identified a small amount of water seepage at the corrosion spot.

CR-RBS-2012-1511 This CR recommends pro-active replacement of 02/27/2012 all pipe and fittings comprising the fire protection water jockey pump (FPW-P3) discharge piping.

The identified condition does not currently cause fire protection equipment to be inoperable or unavailable. The discharge piping of FPW-P3 has excessive corrosion and leakage.

CR-RBS-2012-4629 While performing a monthly walk down of the 07/16/2012 degraded suction tee (FPW-010-073) to the electric driven fire pump (FPW-P2), a step change in degradation was noticed. Based on visual inspection of the component and reinforced by the two visible areas on the tee, water is seeping out.

CR-RBS-2013-3371 There is a pin hole size leak in the pipe elbow of 04/29/2013 FPW-P3, fire water jockey pump, discharge into FPW-P2, electric fire pump, header. The hole is leaking about 25 drops per minute (dpm).

CR-RBS-2014-1059 Corrective Action #14 was issued to document 03/04/2014 the repair of a through-wall leak on line FPW-014-070 that was identified under CR-RBS-2005-03787.

CR-RBS-2014-4979 During the removal of a tagout on FPW-P2 (motor 10/08/2014 driven fire pump), the pump and both diesel fire pumps (FPW-P1A and FPW-P1B) started automatically. Upon investigation, operators concluded that the sensing line to FPW-PS107, the pressure switch for the motor driven fire pump, must have become clogged.

CR-RBS-2014-5761 There is a pin-hole leak in FPW-P3 (jockey pump) 11/11/2014 discharge line in the electric motor driven fire pump room above the eyewash station. It is dripping approximately 4-8 dpm.

CR-RBS-2015-6244 During rounds it was noted by the outside 08/27/2015 operator that there was a noticeable amount of water on the floor by the jockey fire pump. Upon further investigation, a small drip on the pipe was found in between FPW-V112 and FPW-V117.

The operator wiped it down and noticed a small pin-hole leak in this section of piping.

CR-RBS-2016-4235 The chemistry of the fire protection water in the 06/07/2016 storage tanks is monitored each quarter. During sampling, about 200 milliliters of rusty water drained out. Over the last few times that these samples have been collected, the sample flow has been decreasing.

CR-RBS-2016-4759 The main control room received a report that 06/07/2016 there was a rupture on the main fire header in the main admin building/warehouse and that the leak is spraying on safety-related standby motors, which have their associated space heaters energized CR-RBS-2016-8164 A 60 dpm leak was identified coming from a joint 12/04/2016 in the fire water jockey pump discharge line to the B diesel fire pump. The leak is in the section of the pipe that is in the B diesel fire pump room, at the pipe support that is supporting this discharge line.

CR-RBS-2016-8305 The three quarter inch piping between FPW- 12/11/2016 V195, the discharge header drain valve for FPW-P1B, diesel driven fire pump, is degraded and has a pinhole leak where it ties into piping.
