I Inspection Summary: Sustained and continuous control room and plant observa-tions from March 24 to April 2, 1987. Periodic control room and plant observa-tions from April 2 to April 9, 198 Followup on Unit 3 scrams on March 17 and 25, 1987; EHC troubleshooting activities; Unit 3 startup, power ascension and testing activities. Observations of selected surveillances. Review of Unit 2 refueling activitie (Five hundred and thirty total hours (Unit 2 and 3))
Results: One violation (section 8.4) for failure to follow shutdown cooling procedure. Observations of -control room operators' attentiveness led to unresolved items associated with operator watch standing practice (Sections 4.3, 4.4 and 8.1)
.
.
. .
DETAILS Background On March 17, 1987, Unit 3 auto scrammed from APRM high-high flux caused by pressure spikes due_to turbine control valve fluctuations. The root cause of the EHC malfunction was not known, so the licensee remained shutdown for four days to troubleshoot the EHC system. When no problems were found in the EHC system while in a cold static condition, the licensee restarted Unit 3, with NRC Region I concurrence, to troubleshoot the EHC system while in a hot dynamic conditio On March 21, 1987, when Unit 3 reached approximately 2% power, the licensee noted similar EHC system fluctuations that had caused the scram on March 17, 1987. By March 24, 1987, the licensee had still not identified the root cause of the scram. Also, on this same day, NRC Region I received information that control room operators at Peach Bottom had been observed. sleeping while on duty in the control room and were otherwise inattentive to their license obligations. At this point, NRC Region I management determined that sustained control room and plant observation was needed while pursuing substantiation of the informatie On March 24, 1987, Region I institutea around-the-clock coverage of
' licensee activitie The inspection objective was to provide regional management an opportunity to evaluate the licensee's control room an plant oerformance over a sustained period. Of specific concern were licensed operator activities and EHC system troubleshooting. On March 31, 1987 NRC ordered Philadelphia Electric to shutdown Unit 3 and proceed to cold condition. This was completed at 2335 on March 3 Around-the-clock coverage was suspended on April 2, 1987, at the end of the afternoon shift (3:00 p.m. to 11:00 p.m.). Inspection Methodology and Process The inspection began on March 24, 1987, with a continuous review of plant activities by one to three region based or resident inspectors on a three shift rotation (7:00 a.m. to 3:00 p.m.; 3:00 p.m. to 11:00 p.m.;
11:00 p.m. to 7:00 a.m.). Normal resident inspection coverage resumed on April 3, 1987, with additional hours devoted to backshift and weekend tours by the residents and a region based inspecto Areas inspected during this period included NRC licensed operator shift activities, including surveillance test observations and Unit 2 refueling operations, quality assurance / quality control coverage of control room act.ivities, EHC system troubleshooting, plant events that occurred during the inspection period, and LER cause analysi The inspectors used the following criteria during their reviews:

.High Radiation and Contamination Control Areas 4. Control Room and facility shift staffing was frequently checked for compliance with 10 CFR 50.54 and Technical Specifications. Presence of a senior licensed operator in the control room was verified during each visit to the Control Room. (See Section 4.3 for details.)
4. The inspectors frequently observed that selected control room instrumentation indicated values that were within Technical Specification requirements and normal operating l imi t's . ECCS switch positioning and valve lineups were verified based on control room indicators and plant obser-vations. Observations included flow setpoints, breaker positioning, PCIS. status, and radiation monitoring in-strument . Selected control room off-normal alarms (annunciators)
were discussed with control room operators and shift supervision to assure they were knowledgeable of alarm status, plant conditions, and that corrective action, if required, was being taken. In addition, the applicable alarm cards were checked for accuracy. The operators were knowledgeable of alarm status and plant condition . The inspectors checked for fluid leaks by observing sump status, alarms, and pump-out rates; reactor coolant system leakage was discussed with licensee personnel.

4. Shift relief and turnover activities were monitored each shift while on continuous control room coverage, and periodically thereafter, to ensure compliance with administrative procedures and regulatory guidanc .1. 6 ~ The inspectors observed the main stack and both reactor building ventilation stack radiation monitors and recorders, and periodically reviewed traces from backshift periods to verify that radioactive gas release rates were within limits and that unplanned releases had not occurre . The inspectors observed control room indications of fire detection instrumentation and fire suppression cystems, monitored use of fire watches and ignition source controls, checked a sampling of fire barriers for >
-integrity, and observed fire-fighting equipment station . The inspectors. observed overall facility housekeeping conditions, including control of combustibles, loose trash and debris. Cleanup was spot-checked during and after maintenanc Plant housekeeping was generally acceptabl . The inspectors observed the nuclear instrumentation subsystems-(source range, intermediate range and power range monitors) and the reactor protection system to verify that the required channels were operabl .1.10 The inspectors frequently verified that the required off-site electrical power startup sources and emergency on-site diesel generators were operable. A loss of #3 startup source occurred on April 7, 1987 (see section 11.5).
4.1.11 The inspectors verified operability of selected safety related equipment and systems by in plant checks of valve positioning, control of locked valves, power supply availability, operating procedures, plant drawings, instrumentation and breaker pcsitionin Selected major components were visually inspected for leakage, proper lubrication, cooling water supply, operating air supply, and general conditions. No significant piping vibration was detected. The inspector reviewed selected blocking permits (tagouts)
for conformance to licensee procedure No inadequacies were identifie _ . . _ . , . _ _

4.2 Logs and Records The' inspectors reviewed logs and records for accuracy, completeness, abnormal conditions, significant operating changes and trends, required entries, operating and night order propriety, correct equip-ment and lock out status, jumper log validity, conformance to Limiting Conditions for Operations, and proper reporting. The following logs and records were reviewed: Shift Supervision Log, Reactor Engineering Logs, Unit 2 Reactor Operator's Log, Unit 3 Reactor Operator's Log, Control Operator Log Book and STA Log Book, Night Orders, Radiation Work Permits, Locked Valve Log, Maintenance Request Forms, Temporary Circuit Modification Log, and Ignition Source Control Checklists. Control Room logs were compared against Administrative Procedure A-7, Shift Operations. Frequent initialing of entries by licensed operators, shift supervision, and licensee on-site management constituted evidence of licensee review. No unacceptable conditions were identifie .3 Operator Alertness The on-shift inspectors observed control room demeanor, operator alertness and attentiveness, and compliance with other requirements for operator performance as stated in section 4.4 of this report. The inspectors did not observe any licensed operators sleeping while on dut No observations of operators reading non job-related material occurred. The inspectors did not observe any non job-related reading material in the control roo Operators were alert and generally attentive to duties. However, the following observations were made by shift inspectors regarding operator watchstanding practices:
--
Several instances of coffee cups and soda cans sitting on various control panels were note At times, the reactor operators were observed with their feet up on the computer console and leaning back in their chair, giving a perception of inattentio On March 27, 1987, at approximately 5:30 p.m., when the chief operator selected shell warming, he did not notice the position of the Unit 3 Number 3 turbine control valve (TCV). System procedure S.6.3.1.A, " Main Turbine Generator Start-Up", Rev. 19, requires the operator to check that the TCVs are fully open. On March 27, 1987, at approximately 2:30 a.m., the shift superin-tendent and supervisor noticed that the Number 3 TCV was close The test engineer responsible for EHC troubleshooting stated that the EHC system had not been touched for several days. He also stated that the logic card for the Number 3 TCV was pro-bably damaged two days earlier during troubleshootin __ _ _ , _ _ _ __ _ _ _ _ _ _ . . _ _ , . .

On Unit 3 at 10:00 p.m. on March 30, 1987, average power range monitor (APRM) "E" remained bypassed unnecessarily for about 30 minutes after the reactor engineer completed troubleshooting a failed LPRM. APRM "E" was subsequently re-turned to service. Technical Specifications Table 3. require at least two operable APRMs per RPS channel. The inspector verified that APRMs "A" and "C" were operabl During the 11:00 p.m. to 7:00 a.m. shift on March 31 - April-1, 1987, the Unit 3 RHR pump 3B failed to start after two attempts when initiating the RHR shutdown cooling mod After troubleshooting, the on-shift operators determined that the cause for failure to start was that the equivalent Unit 2 RHR pump (28) was in service in the shutdown cooling mode. The two RHR pumps (28 and 38) powered from the same diesel generator are interlocked so that only one may be run at a time. Ap-parently, neither the Unit 3 reactor operator nor the control room shift supervisor realized this fac Failure to follow the shutdown cooling operating procedure on March 31, 1987, resulted in a group IIB primary containment isolation on Unit 3. This is an apparent violation. (See Section 10.4).

On March 27, 1987 between 4 and 5 p.m., a senior licensed individual not on the shift watch list was observed operating equipment on the Unit 3 cormole. The individual did not appear to be under the supervision of tne assigned ifcensed operato These above items except for the apparent violation are collectively grouped as an unresolved item (UNR/277/87-10-01; 278/87-10-01)

Appropriate procedure revisions and training upgrades to improve the knowledge and clarify the definition of attentiveness are neede This item is unresolved (UNR/277/87-10-02; 278/87-10-02). Refueling Operations 5.1 Unit 2 Core Offload Unit 2 core offload began on March 23, 198 The inspector reviewed licensee prerequisites for core offload.

No violations were note .2 Stuck Fuel Assembly (49-40)
When attempting to remove Unit 2 fuel assembly 49-40 from the reactor core, the double blade guide appeared to be caught with the bundle. An unsuccessful attempt was made to free the bundle with special procedure SP-993. With the aid of an underwater camera, the fuel support piece was found raised out of the guide tube. Another special procedure SP-994 was used in an unsuccessful attempt to seat the raised fuel support piece. Continued efforts to seat the fuel support piece and dislodge the bundle nose piece were temporarily abandoned for engineering analysis. The offload sequence was changed to allow fuel movement to continue in parallel with resolution of this fuel assembly removal proble t-"-**P ~ H"' "" "

The inspector. reviewed procedures SP-993 and SP-994 and discussed them with licensee engineers and operators. The inspector will continue to follow the attempts to remove and the causes for the stuck bundl 'No violations were identified'. Surveillance Testing The inspectors observed surveillance tests to verify that testing had been properly scheduled, approved by shift supervision, control room operators were knowledgeable regarding testing in progress, approved procedures were being used, redundant systems or components were available for service as required, test instrumentation was calibrated, work was performed by qualified personnel, and test acceptance criteria were met. Portions of the surveillance tests listed in Attachment 3 were observe The inspector determined that test performance and results review was good, and should be considered a licensee strengt No inadequacies were identifie . Quality Assurance / Quality Control (QA/QC)
The Peach Bottom QA Plan Volume III, Operations Phase, Revision 5, delineates the quality assurance program requirements. Section "S0",
Shift Operations states the following:
--
QC for shift operations is assured by first and second line supervisor operational monitoring and review of Shift Operations is provided by the Superintendent, Operations; the Operations Engineer; and the PORC/NR QA audits and surveillances are performed by the Quality Assurance Division (QAD).
In addition to the above requirements, the licensee's on-site QC group performs monitoring and inspection of shift operations activitie Thus, the assurance of quality for shift operations is provided by reviews performed by (1) the operations line organization, (2) by the PORC and NRB oversight committees, and (3) by the independent QAD onsite QA and QC t
group The inspector reviewed the Quality Assurance Trending and Tracking System (QATTS) printout of QA and QC findings since October 1986. These findings include: QA audits, QA surveillances, QC inspections, and QC monitoring.
I l - -
_ .
. .
The findings are categorized as either nonconformance reports (NCRs),
significant NCRs (SNCRs), recommendations, or QC detailed monitoring checklists (DMCs) reports. There were no documented negative findings with respect to control room operator alertness and attentivenes The inspector questioned the onsite QAD QA and QC site supervisors with respect to control room and licensed operator reviews, particularly during the weekends and backshift periods. The inspector could not identify any case where QA personnel monitored control room activities during the week-end or backshift periods. QC performs periodic detailed monitoring check-lists and independent verifications for I&C surveillances. QC was present in the Control Room for the Unit 3 startup during the period March 10 through 11, 1987. QC personnel provided continuous monitoring, including backshift observations. In addition, QC was present in the Control Room when performing independent verifications signoffs for surveillance test procedures, which included backshift presence (afternoon shift 3-11 p.m.)
in the Control Room on the following days (since October 1986):
--
October 7, 9, 14, 16, 23, 18, 30 (1986)

As previously stated no negative findings related to operator alertness were documented by QC personne No violations were note . Event Analysis 8.1 Unit 3 Scram on March 17, 1987 Unit 3 auto scrammed from 86% power at 2:54 a.m. on March 17, 1987, due to APRM high-high flux. The unit had reduced power on March 16, 1987 from 100% to 86% due to an internal leak in the C2 feedwater heater. Conditions were normal on the scram. The reactor feed pumps (RFPs) recovered the reactor water level decrease. No ECCS were initiated. A group II and III primary containment isolation occur-red, due to the reactor level decrease, which was reset. The recir-culation pumps tripped on the 13 KV non-vital bus fast transfer.

Operators restarted both recirculation pumps. The licensee made an
'NS call and notified the Senior Resident Inspecto _
The licensee determined that the cause of the scram was APRM high-high flux caused by EHC induced turbine control valve fluctua-tions. The unit proceeded to cold shutdown to repair a leak in the C2 feedwater heater to perform other maintenance and to investigate the EHC system malfunction (see section 11.0).
The inspector arrived in the control room at about 6:00 a.m., on March 17, 1987. The unit was in hot shutdown at 400 degrees F with cooldown in progress. The inspector verified that all control rods were full in as indicated by the process computer OD-7 printout and the full core display. The inspector reviewed control room indica-tors, logs, and discussed the event with the on-shift operator Reactor water level dropped to -40 inches as indicated on water level recorders LR-110A and The RFPs recovered level within 25 second The inspector noted that several parameters and their control room strip chart recorders indicated that multiple transients had occurred during the one and a half hours prior to the automatic scram. The
"up and down" spiking (fast oscillations) were apparently caused by the EHC fluctuations. These parameters, instrument numbers and mag-nitude of oscillations are as follows:
MAGNITUDE OF OSCILLATION INSTRUMENT N INCHES % SCALE NR-46A-F/APRM Flux 1/4" noise and 85 i 13% reactor power 1/2" oscillations FR-98/ Steam Flow 0" noise and 1 .2 x 10' lbm/hr 1/8" oscillations PR and FR-97/ Reactor 1/16" noise and (1) 11.0 0.4 x 10' lbm/hr Pressure and Turbine 1/4" oscillations (2) 980 5 psig Steam Flow POR-3660/ Turbine 0" noise and 44 1 4% open Control Valve 1/16" oscillations Position NOTE: There were also oscillations on recorder JR-3157 (Generator MWe).
Based on interviews with shift personnel, the inspector concluded that the operators had not noticed the transients (apparently caused by EHC induced turbine control valve oscillations) prior to the automatic scram. No annunciator nor alarm typer alarms were as-sociated with these recorder indications. Licensee management also noted this apparent inattention to control room indications. As a
.
. .
'
result, the licensee issued a memo to all control room operations personnel on March 19, 1987, reminding them of the need to periodi-cally scan all control room parameters. The specific operators involved were counselled. The issue of operator inattentiveness to instrument recorders is unresolved (UNR/277/87-10-03; 278/87-10-03).
The inspector also reviewed the control room. computer alarm typer and sequence of events log, the draft Upset Report, GP-18 (Scram Review Procedure), and attended PORC meetings on March 19-20, 1987, to re-view the scram. The PORC concluded that the scram was caused by EHC induced oscillations that resulted in turbine control valves (TCVs)
cycling open then closed. On one TCV closing, a pressure spike was sufficient to cause an APRM flux spike high enough to cause a scram on high-high APRM flux. Five of the six APRMs initiated scram sig-nals. APRM Channel D, which did not trip was later tested satis-factorily by the license At the March 19 and 20, 1987, PORC meetings, Unit 3 restart and an EHC test program were approved. The test program consisted of EHC monitoring during bypass valve operation; bypass and turbine valve testing at 25% power; and, EHC monitoring during power ascensio The PORC also approved special procedure SP-991, " Response to Unit 3 Reactor Parameter Abnormalities", Rev. O. SP-991 provided operators with instructions if EHC problems reoccurre As part of the scram reduction program, the ISEG is writing an Event Report. The inspector will review the Event Report, the final Upset Report, an'd the LER, when they are issue .2 Unit 3 Scram on March 25, 1987 After a four day outage following the scram on March 17, 1987, the unit was restarted on March 21, 1987. Prior to the restart, the EHC system was tested in cold, static conditions and no abnormalities were observed. To facilitate testing of the EHC system under hot, dynamic conditions, the reactor was subsequently placed in a hot standby conditio The investigation of the EHC system malfunction continued on March 21 through 25, 1987. A special operating instruction was in place on March 21, 1987, to provide the operating staff instructions, should reactor parameter abnormalities occur similar to those experienced prior to the scram on March 17, 198 The spiking of the turbine bypass valves reappeared during the hot standby condition on March 21 through 23, 1987. In order to facilitate the EHC investigation, certain electronic circuit cards in the EHC system were pulled or replaced with similar ones from Unit 2 (see section 9 of this report, for details). With this configuration, the spiking of the bypass valves stopped at approximately 10:30 p.m., on March 23, 198 .
. .
~
However, turbine bypass valve oscillation (cycling) was observed on March 24, 1987, when the reactor pressure was increased to the normal pressure control setpoin The unit auto scrammed on low reactor water level at 4:02 a.m., on March 25, 198 Prior to the scram, the reactor was in a hot standby condition, with reactor at rated pressure and 1/4 bypass valve open (power level less than one percent). Troubleshooting was in progress on the EHC system to determine the reascn for the noted bypass valve oscillations observed on March 24, 1987. A test engineer lifted an EHC lead in the electronic circuit (see section 9 of this report, for details) causing all bypass valves to open. The resulting level swell in the reactor caused a high level trip of the C reactor feedwater pump (RFP) which was the only RFP then runnin The loss of the RFP and the blowdown due to the open bypass valves caused the reactor level to drop to about -35 inches. The unit scrammed on low reactor water level and primary containment group II and III isolations occurred at 0 inches. The operator restarted the C RFP and recovered the reactor level. No ECCS actuated and condi-tions were normal on the scram. The unit was maintained in a shut-down condition to conduct further EHC troubleshooting.

The inspector will review the LER when it is issued. No violations were note .3 Unit 2 Primary Containment Isolation on March 28, 1987 A group IIB primary containment isolation occurred on Unit 2 while in cold shutdown at 10:20 a.m., on March 28, 1987. The isolation caused the RHR shutdown cooling suction valves M0-17 and MO-18 to close. Shutdown cooling was not in service (RHR pump was secured)
at the time of the isolatio Fuel movements were in progress on the unit. The cause of the isolation was pulling two fuses associated with the blocking for the scheduled 4160 volt E-12 bus outage. At 10:40 a.m., the licensee replaced the fuses, reopened valves MO-17 and 18, and changed the blocking to lifting leads for the E-12 bus electrical isolation. An ENS call was initiated for the required four hour notification. The unit was in day 17 of the 71 day scheduled refueling outage, with core offload about 45%
complet The inspector reviewed control room logs, the suspected licensee event report (LER), and the electrical schematic drawings. Fuses 10A-F1A and 10A-F2A were pulled as part of the blocking permit (tagout) for MRF No. 2-54L8607538. Pulling these two fuses caused relay 10A-K114A to de-energize which resulted in a group IIB primary containment isolation on 75 psig reactor pressure. This caused RHR valves MO-17 and 18 to clos .

The inspector attributes the cause of the event to a blocking error by the licensed operator. The licensee made the required four hour ENS call, recovered the shutdown cooling capability within 20 minutes, and intends to submit an LER for the event. The LER and associated corrective actions will be reviewed in a future inspectio No violations were note .4 Unit 3 Primary Containment Isolation on March 31, 1987 A group IIB primary containment isolation. occurred on Unit 3 at '
9:25 p.m., on March 31, 1987. The operator was preparing to place shutdown cooling into service in accordance with procedure-S.3.2.C.1, " Shutdown Cooling Mode - Manual Start and Shutdown",
Rev. 17. While performing the system flush prior to starting shutdown cooling, suction valves M0-17 and 18 isolated on high reactor pressure signal (75 psig). The licensee determined that an in-rush of reactor water and subsequent flashing to steam {
caused a pressure spike and the 75 psig isolation to actuat Actual reactor pressure was approximately 45 psig. The licensee reset the isolation and established shutdown cooling by reopening valves MD-17 and 1 The inspector monitored control room operations, actions, and reviewed control room logs. The preliminary licensee event report (LER), the electrical schematic drawings, and procedu're S.3.2.C.1,
" Shutdown Cooling Mode - Manual Start and Shutdown", Rev. 17, were also reviewed. Procedure S.3.2.C.1 step #7 requires a flush of 40 inches (reactor level) through the shutdown cooling lines to the toru Valves are required to be operated in the following order:

Jog open M0-34 The apparent reason for this order is to minimize a possible water hammer and inrush effect. The inspector noted that the operator opened M0-15 prior to opening MO-17 and 18. This apparently caused the inrush of reactor water and resulted in actuation of the 75 psig group IIB primary containment isolatio E'

Technical Specification 6.8.1 requires that written procedures be established, implemented, and maintained per ANSI N18.7-1972 (sections 5.1 and 5.3) and per Appendix "A" of Regulatory Guide 1.33 (November 1972). Regulatory Guide 1.33, Appendix A, Section C states that procedures for the Shutdown Cooling System shall be prepared. Section 5.3.4.2 of ANSI N18.7-1972 requires procedures for shutdown including decay heat removal. Failure.to follow step Number 7 of procedure S.3.2.C.1 in the correct order is an apparent violation of TS 6.8.1 (278/87-10-04).
The licensee made the required ENS call, established shutdown cooling, and intends to submit an LER for the even The LER and associated corrective actions will be reviewed in a future inspectio .5 Loss of Number 3 Startup Offsite Power Source on April 7, 1987 At 12:18 a.m., on April 7, 1987, Peach Bottom lost the Number 3 startup (SV) source. This was apparently caused by a loss of a 220 KV transmission line in the grid, with subsequent load dispatcher switching,' causing a trip of the 220-34 line (the source of offsite power for the #3 SU). Thus, a loss of one of the two offsite power sources occurred. The E-1 diesel generator (DG) was running at the time for weekly surveillances and was carrying the E-13 bus in parallel with the #3 SU (normal power supply). When the #3 SU source tripped, the E-1 DG picked up the emergency buses that were being supplied (normally) by #3 SU. These buses included two for Unit 2 (E-22 and E-42) and two for Unit 3 (E-13 and E-33). Two of the non-vital 13 KV buses normally supplied by the 3# SU source (#2 and
- 3 bus) were also lost. The E-1 DG was loaded to about 3500 KWe (rated for 3100 KWe) and frequency dropped to about 57-58 Hz. Since there was no loss of power on the bus no load shedding occurred which caused the diesel overload condition. (The E-1 DG was subsequently inspected with no noted problems.) The lower frequency caused the 2B RPS MG set (Unit 2) and the 3A RPS MG set (Unit 3) to trip. This resulted in a half scram on both units, a half group I isolation on both units, an outboard isolation group III on Unit 2, and an-inboard isolation group III on Unit The half scrc.u and half group I isolations did not cause any actions. The group III half (inboard or outboard) isolations caused a loss of normal reactor building ventilation and an isolation of normal containment ventilation. The standby gas treatment system (SGTS) was in service at the time, supplying ventilation for the Unit 2 refueling floor and the Unit 3 drywell. Both units were in the cold condition as required by NRC Orde No fuel movements were in progress on Unit 2 at the time. The licensee reset the group III half isolations, restored power to the non vital Number- 2 and 3 buses, and aligned the emergency buses per plant procedures (all emergency buses were swapped over to the Number

2 SU source, and the E-2 DG was started to supply the E-22 bus). At 6:30 a.m., the Number 3 SU source was returned to service. The licensee then realigned the emergency and non-vital buses to the normal shut down lineup. The licensee determined that this event should have been reported due to the group -III half isolations. At 11:05 a.m., an ENS call was mad The inspector discussed this event with control room operators and operations engineers. The inspector reviewed control room logs, operating procedures, and electrical schematic drawings. The inspector had no further questions at this time. The LER will be reviewed in a future inspectio . Turbine Electro-Hydraulic Control (EHC) System Troubleshooting As discussed in section 8.2, the licensee, in an attempt to isolate and correct the spiking (rapid opening and closing of turbine control valves) observed on the control room recorders (section 8.1), replaced various printed circuit boards (cards) in the Unit 3 EHC system with cards from the Unit 2 EHC system. Unit 2 is currently in a refueling outage. The following is a general chronology of actions:
--
March 17-20, 1987, shutdown testing of EHC did not identify any problem March 21, 1987, plant startup and heatup, dynamic testing starte Spiking of bypass valve noted which caused opening of about one second duratio March 22, 1987, various cards pulled and replaced, (no clear record of which cards) spiking remaine March 23, 1987, changed Pressure Load Gate (PLG) card, no change in oscillations noted.

March 24, 1987, 10:00 p.m., number one (1) bypass valve was observed oscillating between 50 and 75 percent open with the plant at normal operating pressure. Troubleshooting was initiate March 25, 1987, 4:02 a.m., reactor scram when lead was lifted during troubleshooting. The reactor scram occurred as described in section 8.2 of this report. The lead had been lifted in accordance with procedure A-42.1, " Temporary Circuit Modifications During Troubleshooting of Plant Equipment".
Subsequent to the scram the licensee determined that all bypass valves opened when lead number TB 702-14 (Electrical Schematic M2-560 Sheet 1 -
Revision 5) was lifted because lifting the lead caused a large increase in the output of the bypass valve amplifie Following the scram the licensee decided to: (1) replace the PLG with the original card because oscillations observed on March 23, 1987, occurred after the Unit 2 card was installed. (2) Calibrate the Unit 2 cards (A that were to remain in the
&
UnitB 3pressure EHC. Itamplifiers and the was originally A&B SLRC thought that the cards)' Unit 2 cards were cali-brated to the same attenuation settings as Unit 3 cards. It was later determined that Unit 3 SLRC settings were different than Unit 2. (3)
Replace the EHC cooling fan Five out of nine cooling fans had been identified as out of service on March 23, 198 The inspectors observed that the calibration activities being conducted by the licensee were in accordance with the General Electric Turbine Line Up Instruction Number 170 x 387 and 170 x 388. The licensee had 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> coverage being supplied by a corporate PEco EHC engineer and a vendor representativ During discussions and review of SLRC alignment data, the inspector learned that the SLRC card was basically a notch filter that attenuated the magnitude of pressure oscillations of the steam line natural frequency of 0.9 hertz and several harmonics. The Unit 2 and 3 steam lines have the same natural frequency but the Unit 3 SLRC card re-quires more attenuation indicating that oscillations are of a larger magnitude than at Unit Licensee representatives stated that the oscil-lations experienced on March 24, 1987, could have been the result of using the Unit 2 SLRC cards. No theory about the cause of the original spiking which caused the trip on March 17, 1987, had been formulated. All cards removed from the Unit 3 EHC system will be sent to vendor for dynamic testin Subsequent to the calibration of the EHC cards the licensee connected a 13 point transient tape recording device and a 12 channel strip chart recorder. During the plant startup and heatup on March 26 and 27,1987, the inspectors and the licensee observed the recorder traces which were steady. At about 1:00 a.m., on March 27, 1987, the last new ventilation fan was installed. During this activity several spikes and oscillations were observed on the recorder char The parameters that were affected were:

Points 1 and 2, pressure sensor inputs to A and B pressure amplifier circuit Points 10 and 11, A and B pressure amplifier output Point 12, bypass valve positio The spiking was discussed with the on-duty test engineer. He also noted that during previous troubleshooting activities on March 23, 1987, he had heard noises such as EHC panel ventilation fan blades hitting the fan housings which seemed to correspond to EHC spikes. Ventilation fans observed to be defective were disabled at that time. During the same period the A and B pressure amplifiers and the A and B SLRC cards were replace EHC spiking stopped later on March 23, 198 The inspector agreed with the licensee test engineer that, although not conclusive, it appeared that the March 17, 1987, scram could hav'e been caused by the electrical noise induced by defective EHC ventilation fan Oscillations in the bypass valve position observed on March 24, 1987, could have been caused by the differences in calibration settings of the Unit 2 SLRC cards installed in the Unit 3 EHC syste 'The inspectors observed the recorder traces to be very steady after the fan was electrically connecte The licensee is required to submit LERs regarding both the March 17 and March 25, 1987 scram No violations were identifie . LER Analysis 10.1 Scope The inspector conducted a specia! review of LERs submitted to the NRC for the period 1985 to present for both Units 2 and 3. The review determined the time of day for those LERs involving personnel error. This includes personnel error induced events, and those events that were initiated by other root causes (i.e., non personnel error) which may have been complicated or made worse by subsequent personnel error. For the reportable events occurring on the back shifts (primarily 11:00 p.m. to 7:00 a.m.) or on the weekends, the review determined if the reported personnel error was caused or made worse by any operator inattentiveness to the control .2 Conclusion The inspector reviewed all Peach Bottom LERs from 1985 to presen Attachment 2 lists all LERs that involve personnel error based on NRC root cause analysis during previous routine inspection For the LERs caused by or made worse by licensed operator errors

during backshift times, the inspector identified one case on a backshift where operator inattention to duty was potentially involved (LER 3-85-02) other than the scram on March 17, 1987 -
section 8.3. The majority of-the backshift errors occurred during plant startups, : shutdowns, or equipment blocking evolutions, which do not appear to have been related to operator inattentivenes Further, NRC action regarding personnel errors is unresolved pending a licensee review of all reportable events for indications of operator inattentivenes (277/87-10-04; 278/87-10-05)

Senior reactor operators worked less overtime than reactor operators and no deviations were needed nor processe The inspector reviewed work hours on the day of the Unit 3 scram due to EHC problems on March 17, 1987 (see section 11.1). This included all control room personnel and related overtime hours for that period. All of the operators worked an eight hour shift (11:00 p.m. - 7:00 a.m.)
that day. Neither the Unit 3 reactor operator nor the senior operators on shift worked any overtime for that period. The inspector concluded that excessive work hours was not a factor in the March 17, 1987, apparent inattention to control room indications and resultant automatic scra The inspector asked the licensee for the average overtime hours for 1986 for licensed operators. This information was not readily available and it will be reviewed in a future inspectio No violations were note . Exit Interview Meeting The inspection ended on April 9, 1987. An exit interview was held on April 9,1987, to discuss the findings and conclusions by the inspection tea .
