SUBJECT:
INSPECTION PLANNING REVIEW (IPR)- RIVER BEND STATION
Dear Mr. Edington:
On December 2,1998, the NRC staff completed a unique Inspection Planning Review (IPR) of River Bend Station. The staff normally conducts Semiannual Plant Performance Reviews for all operating nuclear power plants to develop an integrated understanding of safety performance and adjust inspection resources. However, due to the suspension of the Systematic Assessment of Licensee Performance process, we implemented an abbreviated inspection Planning Review for plant issues and to develop inspection plans. The IPR for River Bend Station involved the participation of both Reactor Projects and Safety divisions in evaluating i
inspection results and safety performance trends for the period April 23 to October 28,1998.
This IPR provided NRC management with a current summary of licensee performance trends since the last Plant Performance Review.
Based upon this review, inspection resources have been prioritized and scheduled. No changes have been made to the inspection resources for your facility. contains an historical listing of plant issues, referred to as the Plant issues Matrix (PIM), that was considered during this IPR process to arrive at an integrated view of licensee performance trends. The PIM includes only items from inspection reports and other docketed correspondence between the NRC and Entergy Operations, Inc. The IPR may also have considered some predecisional and draft material that does not appear in the attached PIM, including observations from events and inspections that had occurred since the last NRC inspection report was issued, but had not yet received full review and consideration. is a general description of the PIM table labels. This material will be placed in the NRC Public Document Room.
This letter also advises you of our planned inspection effort resulting from the River Bend Station IPR. It is provided to minimize the resource impact on your staff and to allow for scheduling conflicts and personnel availability to be resolved in advance of inspector arriva?
onsite. Enclosure 3 details our inspection plan for River Bend Station over the next 8 months.
The rationale or basis for each inspection outside the core inspection program is provided so that you are aware of the reason for emphasis in these program areas. Resident inspections are not listed because of their ongoing and continuous nature. We will inform you of any changes to the inspection plan.

PLANT ISSUES MATRIX RIVER BEND DATE TYPE SOURCE ID SFA TEMPLATE ITEM DESCRIPTION CODE 10/23/98 POS IR98-19 NR OPS 1C The licensee had effectively communicated to plant personnel the importance of identifying and resolving C
operator workarounds and the licensee's efforts to identify operator workarounds were being adequately implemented. The workarounds documented by the licensee on the workaround ust were consistent with the definition in the established guidelines.
The licensee had performed limited scope assessments of operator workarounds but had not applied any formal evaluatir'n criteria. Past assessments of workarounds had not addressed the potential for operator error during, or resulting from, the implementation of workaround compensatory measures. Despite the informal nature and limited scope of the assessments, the licensee appeared to be emphasizing the timely resolution of operator workarounds.
10/20/98 NEG IR 98-18 NR OPS 1A Nuclear equipment operators demonstrated poor attention to detail during the Division I diesel generator C
24-hour run in that they failed to property monitor governor oil level during the surveillance. Subsequently, unacceptable power swings were observed when oillevel dropped below that required for proper governor operation. Planned corrective measures to address the oil leak and nuclear equipment operator performance were acceptable.
10/14/98 POS IR 98-13 NR OPS SA SB SC Corrective action processes were well designed and effectively implemented.
C 10/14/98 POS IR 98-13 NR OPS SA The recent quality assurance audits were effective in the identification of specific and programmatic C
deficiencies within the corrective action program.
9/19/98 NEG 1R 98-17 NR OPS 1A 3B Operator awareness of most plant problems was considered good but in one inctance operators did not C
demonstrate a proper understanding of the potential plant response to a failed -22 VDC electro-hydraulic controls bus. The bus was degraded at the time. Bus failure, absent operator action, would have resulted in closure of the main steam isolation valves. Main steam isolation valve closure would have significantly complicated any subsequent operator response. Similar operator knowledge observations were made in NRC Inspection Report 50-458/98-05. As documented in that report, Operations personnel did not understand the basis for operability when questioned about reactor core isolation cooling, p! ant stack monitor, and hydraulic control unit problerns.
7/4/98 NEG 1R 98-15 SE OPS 1A 3A While a trend in human performance problems was identified approximately one month prior to the fire LF pump failure, short-term corrective actions were not timely. A nuclear equipment operator (NEO) demonstrated poor self-checking practices when he failed to properly reposition the diesel fire pump fuel oil tank outlet valve per clearance order specifications, which resulted in pump failure during postmaintenance testing. This was the fourth " plant impact" type of Operations human performance problem identified during the past three inspection periods.

PLANT ISSUES MATRIX RIVER BEND DATE TYPE SOURCE ID SFA TEMPLATE ITEM DESCRIPTION CODE 6/1/98 VIO 1R 98-12 SE OPS 1A 3A One violation of Technical Specifications 5.4.1 (procedures) was identified for operating a different breaker SLIV LF than specified on a clearance order. The Division il diesel generator output breaker was mistakenly operated, instead of the C residual heat removal pump breaker, which momentarily rendered the diesel generator inoperable. This was the third operator related human performance problem in the last two report periods which has affected plant operation.
5/16/98 NEG 1R 98-08 SE OPS 3A 1A A nuclear equipment operator demonstrated poor self-checking practices in that he had failed to properly LF reposition plant valves on two occasions. In the first case, cooling water was inadvertent!y secured to the B feedwater pump speed increaser. In the second instance an accumulator pressure switch, that activates an accumulator trouble alarm in the control room, was inadvertently isolated for over three weeks 4/27/98 STR 1R 98-08 NR OPS 1A The plant startup was orderly and the control room supervisor demonstrated excellent command and C
control during the evolution. Control room briefs were thorough and the control room supervisor provided exceptional guidance and direction to the crew.
4/13/98 POS IR 98-08 NR OPS 1A The plant shutdown was well controlled. The control room supervisor provided appropriate and timely C
briefings during the evolution and properly anticipated entry into the emergency operating procedures when the plant was scrammed.
3/17/98 NEG IR 98-05 NR OPS 18 Operations' respanse to the unexpected actuation of a fire water sprinkler system in Tunnel F was effective C
at controlling the event. However, management expectatkm were not met in that three-way 4
communications were not consistently utilized and comma.6 and control was not initially streamlined through the control room supervisor.
2/21/98 NEG IR 98-04 NR OPS SA 58 4B Operations and Engineering erroneously concluded that only one abnormal operating procedure and no C
emergency operating procedures could be impacted by standby gas treatment system (SGTS) induced dp across the auxiliary building. The actual operation of the SGTS following an event and the force required to open doors with one train of the SGTS in operation were not appropriately considered in the evaluations.
Errors made in one calculation resulted in significantly underestimating the force required to open doors.
in addition, when an engineering manager and supervisor were unable to enter the auxiliary building (with one train of SGTS in operation) they failed to inform upper management and Operations of this information. Consequently, misperceptions regarding the difficulty accessing the auxiliary building were not corrected.

2/4/98 POS IR 98-04 NR OPS 18 3A Operations' response to a control rod drive control circuit power supply failure was prompt and effective.
C The flow control valve failed closed and operators had to establish manual controlin the field.
1/10/98 POS IR 97-19 NR OPS 3A A nuclear equipment operator trainee demonstrated excellent attention to detail during a diesel generator C
surveillance. While looking for fluid discharge on the cylinder head test valves, the operator noticed oil residue on piping adjacent to the number eight cylinder (versus the cylinder head test valve itself),

system. PASS has been out of service for approximately 50% of the time during the past 10 months.
Repairs were often not performed in a timely manner and the overali material condition of the system was poor.
12/29/97 STR 1R 97-12 NR OPS 1C 3C The inspector concluded that the requahfication examinations were well constructed and disenminated at C
the appropriate knowledge level. The licensee responded promptly and effectively to an identified examination security vulnerability.
12/29/97 STR 1R 97-12 NR OPS 1A 3A Crews observed practiced good, consistent communications and exhibited good teamwork during the C
dynamic simulator scenarios. Crews met all planned critical tasks and successfu!!y passed the requalification examination. The licensee's remedial training program conformed to the administrative requirements and appeared to be effective.
12/29/97 STR 1R 97-12 NR OPS 3C Licensee eva!uators were consistent and objective in their evaluations and their overall performance was C
considered a strength. Critiques effectively identified strengths and weaknesses. The extensive involvement of operations management was considered a strength.

PLANT ISSUES MATRIX RIVER BEND DATE TYPE SOURCE 10 SFA TEMPLATE ITEM DESCRIPTION CODE 10/14/98 POS IR 98-13 NR MAINT SA Self-assessments were comprehensive and of appropriate scope and depth to meet their objectives. The C
type and number of findings indicated the assessments were thorough and appropriately self-critical.
9/19/98 NEG IR 98-17 NR MAINT 2A Plant material condition was generally good with some significant deficiencies. Material condition concems C
included: 1) degraded Division I and 11 diesel generator control air systems, requiring the use of operator actions and non-safety related equipment to maintain the diesels operable; 2) a fuel leak; and 3) an erratic emergency response information system real time computer. Conversely, the degraded -22 VDC electro-hydraulic controls power supply was repaired this inspection period.
8/8/98 POS IR 98-15 NR MAINT SA 5B SC Management involvement to address a through-wall feedwater flow venturiir:strument line crack was C
excellent. Managers responded to the site in the evening to assess the problem and plan corrective measures. The resultant maintenance reflected careful planning, good coordination with OperatK)ns, and appropriate consideration of plant risk.
8/8/98 NCV IR 98-15 LIC MAINT 28 3A A noncited violation was documented to address three licensee identified instances where surveillances were not performed per Technical Specification (TS) 5.4.1 required procedures. Missed surveillances included: (1) the overall annulus bypass leakage evaluation; (2) a high pressure core spray pump vibration surveillance; and (3) the 2-year diesel fire pump inspection. Additionally, Technical Requirements Manual (TRM) Surveillance Requirement (SR) 3.3.2.1.12, Source Range Monitor Channel Function Tests, were not performed prior to plant startup on April 27, but did not constitute a violation of NRC requirements.
Subsequent performance of the surveillances was satisfactory. Contributors included inadequate management oversight, poor implementation of scheduling activities, inadequate training, weak surveillance procedures, and confusing surveillance tracking methods. The licensee's investigation was thorough and self-critical Planned corrective actions were sound and expansive.
8/8/98 NEG IR 98-15 LIC MAINT 2A Plant material condition was, overall, good. Material condition concems included repeated trips of instrument air compressors, a through-wall crack of a feedwater flow venturi instrument line (repaired), a degraded -22 VDC electrohydraulic control bus, elevated axial vibration on the high pressure core spray pump, and an erratic emergency response information system transient analysis computer. The instrument air compressor trips were not of major concern due to automatic backup features. Material condition improvements included restoration of the Division 11 suppression pool pumpback pumps and the suppression pool cleanup system. Suppression pool cleanliness was substantially improved.
6/27/98 POS IR 98-12 SE MAINT 2A Plant material condition was, overall, very good, with a few relatively minor exceptions. Material condition LF concems included two out of service suppression pool pumpback pumps, an out of service suppression pool cleanup system, and repeated trips of instrument air compressors. The instrument air compressor trips were not of major concem due to automatic backup features.

PLANT ISSUES MATRIX RIVER BEND DATE TYPE SOURCE ID SFA TEMPLATE ITEM DESCRIPTION CODE 5/16/98 NEG 1R 98-08 LIC MAINT 3C Causes for a seal oil leak and excessive main generator hydrogen leakage included weak contractor oversight and poor coordination of maintenance, without adequate verification of critical steps, dunng refueling outage number 7. A sealant plug was not properly reinsta, led and hydrogen seal assembly bolts were not properly torqued. Conversely, corrective maintenance performed during the forced outage was thorough, well controlled and effective at correcting the problems.
5/16/98 POS IR 98-08 NR MAINT 2A Plant material condition was very good. Material condition concerns included an out of service suppression C
pool cleanup system, excessive standby gas treatment system induced differential pressure across the auxiliary building, and a sealleak on feedwater pump B. Conversely, action was taken to correct main generator hydrogen leakage, a high pressure turbine steam leak, and a control building HVAC chiller.
Additionally, a " black board" was achieved in the control room.
4/4/98 POS IR 98-05 LIC MAINT 2A Overall, plant material condition was good. Material condition challenges included excessive main generator hydrogen leakage, a high pressure turbine steam leak, excessive d:fferential pressure across the auxiliary building when the standby gas treatment system was in operation, and an inoperabie control building chiller. The emergency response information system transient analysis computer and the post accident sampling system were repaired and retumed to service.
2/25/98 NEG IR 98-05 SE MAINT 3A 18 Poor self-checking on the part of two instrument and controls technicians resulted in the inadvertent LF isolation of cooling water to the reactor water cleanup nonregenerative heat exchanger and the reactor recirculation pump bearings and seals. Operations
- response to the event was prompt and effective.
2/21/98 WK iR 98-04 LIC MAINT 2A Overall, plant material condition was generally good. However, several significant material condition problems still challenged the plant. including excesWve main generator hydrogen leakage, main turbine steam leakage, a failed emergency response inforru4ron system computer, an inoperable postaccident sampling system, excessive dp across the auxiliary building due to high suction from the SGTS, and an inoperable control building HVAC chiller. Conversely, a suppression pool pumpback pump was repaired and retumed to service.
2/20/98 NEG IR 98-04 NR MAINT 3C 5B A special auxiliary building accessibility test was poorly coordinated, which minimized the value of the test.
C Specifically, when two trains of the SGTS were running, door testing was initiated and completed before the peak building differential pressure (dp) was reached. Additionally, when one train was running, the building dp was not permitted to stabilize after an initial entry resulted in pressurizing the building above the test pressure As a result, only one relatively well built indMdual gained access through the door at the test dp. Finally, problems with the test were not appropriately communicated to plant management, who had believed that the test was successful.
2/12/98 STR IR 97-09 NR MAINT 28 The licensee's online and shutdown maintenance risk-assessment programs were well developed and C
implemented, with use of the equipment-out-of-service computer program for both online and shutdown risk-assessment.

2/12/98 WK IR 97-09 NR MAINT 2B The governing procedures and guidelines for implementing the Maintenance Rule program were weak, as C
evidenced by a lack of clear boundary definitions, function definitions, and quantitative performance measures.
2/12/98 VIO IR 97-09 NR MAINT 2A 28 Four examples of a violation of 10 CFR 50.65(a)(2) were identified for the failure to demonstrate that the SLIV C
performance or condition of six systems, structures, or components had been effectively controlled through the performance of appropriate preventive maintenance.
1/10/98 MISC IR 97-19 NR MAINT 2A While overall plant material condition was good, there were notable 3xceptions. The inspector noted C
material condition concerns involving excessive main generator hydrogen leakage, an inoperable post accident sample system, an inoperabie suppression pool pumpback pump, a degraded control rod drive pump, a failed containment isolation damper, and air entrapment in the instrument sensing lines to safety related instruments. Conversely, spent fuel cooling Pump 1B and the suppression pool cleanup mode of the attemate decay heat removal system were repaired and retumed to service.
1/10/98 WK IR 97-19 NR MAINT 3A On-line risk assessments were not always thorough. In one instance operators ir appropriately assumed C
that a delay in placing standby service water pumps in service would not adversely affect the availabihty of the standby service water pumps or the associated diesel generators. In another case, the potential consequences associated with a freeze seal failure were not properly considered in the risk assessment.
1/8/98 VIO IR 98-04 SE MAINT 2B Petcock valves on maintenance actuators for containment purge and ventilation Dampers HVR-AOV-128, SLIV LF 165 and 166 were not appropriately controlled and were not positioned in accordance requirements contained in plant drawings. Consequently, the mispositioning of one of the petcock valves resulted in rendering Damper HVR-AOV-165 inoperable. The lack of controlled precluded opportunities to identify this problem prior rendering the damper inoperable.
11/29/97 MISC IR 97-17 SE MAINT 2A Plant material condition was generally acceptable. Concems were identified with damaged drywell LF insulation, the inoperable SPC mode of the alternate decay heat removal (ADHR) system, an inoperable postaccident sampling system, excessive main generator hydrogen leakage, an inoperable spent fuel cooling pump, and a degraded control rod drive (CRD) pump.
11/29/97 NCV IR 97-17 LIC MAINT 3C Some procedures goveming local leak rate testing for containment isolation valves were inadequate because testing was specified with lift check valves in the air pathway. In some cases, the test configuration resulted in unacceptably low test pressures, while in other cases the effects of the test configurations were not known. Corrective actions to address this finding were comprehensive.

The causes for these problems were (1) poor coordination and preparatxm for maintenance and/or testing; (2) questionable understanding of design; (3) a less than expected questioning attitude; or (4) failure to adhere to procedural requirements. This has been noted to be a continuing problem.
11/29/97 NEG IR 97-17 NR MAINT 3A 3B Mechanical maintenance department personnel inappropriately deferred the overall air lock leak rate test C
until after startup without considering how the use or maintenance of the air lock could have affected its operability.

11/14/97 STR IR 97-14 NR MAINT 2A Improvements to material condition which were implemented in RO-7 included: suppression pool cleanup C
system; upgraded ECCS strainers, Cleaning of Div 11 RHR heat exchangers; repairing approximately 150 valves; and the overhaul of Rx FW pumps A and C.
11/14/97 NEG 1R 97-14 NR MAINT 3B Test engineers applied weak testing practices by failing to property configure a local leak rate test manifold C
to prevent leakage between the pressure source and the test boundary, during surveillance testing of the inboard and outboard MSIVs.
10/30/97 NEG IR 97-17 NR MAINT 3A During local leak rate testing, maintenance technicians failed to vent the leak rate monitor bypass C
manifolds, as specified by the procedure. This was the second time that a leak rate monitor bypass manifold venting problem was identified in the past.
10/28/97 POS IR 97-16 NR MAINT 2A SC To improve material condition related to fuel protection, the licensee installed a permanent instrument air C
and backup nitrogen supply for the containment building pneumatic gate seals and main steam line plugs.
10/28/97 POS 1R 97-16 NR MAINT 2A To improve the material condition of the suppression pool, the licensee installed permanent protective C
barriers in various locations and a permanent cleanup system.
10/28/97 POS IR 97-16 NR MAINT 2A SC To improve material condition related to fuel handling, the licensee installed a high intensity lighting system C
in the reactor vessel, and mounted a high resolution video camera on the refueling mast to assist in fuel bundle placement and identification.

declaration of a notifcation of an unusual event, all events reported to the NRC operations center since June 1996 were property evaluated and classified. Changes made to the emergency plan were implemented in accordance with 10 CFR 50.54(q). Prccedure changes accurately reflected changes in the emergency plan. The emergency preparedness staff was well trained and maintained good awareness of industry issues. The emergency response organization training program was implemented satisfactorily.
Annual reviews of the emergency plan, implementing procedures, emergency action leve:s, and letters of agreement were property performed and documented. Emergency response facilities were property equipped and maintained in a state of proper operational readiness. The corrective action request p'ocess effectively tracked resolution of emergency preparedness issues, and these issues were resolved in a timely manner.
