EXECUTIVE SUMMARY Hope Creek inspection Report 50-354/88-22 July 12, 1988 to August 29, 1988

<

Operations: A violation was cited for poor control of operating equipment based on multiple personnel errors that resulted in the wrong valve being disabled and its subsequent return to service being overlooked. The incorrect valve alignment had minimal safety significance. The inspectors reviewed the operator response and equipment performance associated with an August 26 turbine trip / reactor scram, a Technical Specification required shutdown initiated on July 19, and recirculation system runbacks on July 28 and August 15. The inspectors found operator response and equipment performance to have been acceptable; however, the inspectors will evaluate corrective actions for reactor vessel level transmitter inaccuracies (ringing)

based on the transmitter oscillations experienced during the August 26 reactor scra Radiological Control:

-

Two licensee identified violations were reviewed concerning locked high radiation doors found unlocked and omitted sample analyses on a liquid effluent release. Corrective actions were reviewed and found acceptabl Maintenance / Surveillance: The inspectors found that implementation problems existed in the corrective actions taken for previously identified weaknesses in the control of scaffolding. The tritial submittals for NRC Bulletin 85-03 on motor-operated valve settings were reviewed and found acceptabl Emergency preparedness: The inspectors reviewed the Unusual Event declarations and notifications fot the July 19 and August 26 Unusual Events and concluded that the event declaration on August 26 was slower than it should have bee Security: The quarterly submittal of the Safeguard Event Log was reviewed and the response actions were found acceptabl Engineergg/ Technical The inspector concluded that PSE&G poorly controlled an unresol__ved Support:

Details SUMMARY OF OPERATIONS The unit entered this report period at full power and continued power operations until a test equipment malfunction caused a turbine trip and reactor scram on August 26. The reactor was restarted and was on line on August 29. In addition to the reactor scram, on July 19 a shutdown was initiated from full power due to both trains of the main steam isolation valve (MSIV) sealing system being inoperable. The  ;

shutdown was terminated two hours later. Further, intermediate runbacks of the recirculation system occurred on July 28 due to a personnel error during testing and on August 15 due to a pressure switch failure in a reactor feed pump oil syste On August 29, Hope Creek plant management was changed, in that Stanley LaBruna, previously General Manager - Hope Creek Operations, was promoted to Vice President - Nuclear Operations, and Joseph Hagan, previously Maintenance Manager, was promoted to General Manager -

Hope Creek Operation . OPERATIONS (71707, 71710) Inspection Activities On a daily basis throughout the report period, the inspectors verified that the facility was operated safely and in conformance ,

with regulatory requirements. Public Service Electric and Gas '

'PSE&G) Company management control was evaluated by direct

,

observation of activities, tours of the facility, interviews and discussions with personnel, independent verification of safety system status and Limiting Conditions for Operation, and review of facility '

records. These inspection activities were conducted in accordance with NRC inspection procedures 71707 and 71710 and included .<eekend inspection on August 14 and deep backshift inspections on August 21 and 2 .2 Inspection Findings and Significant Plant Events On August 26 at 6:26 p.m., a reactor scram from full power occurred when the main turbine tripped during functional testing of the turbine thrust bearing wear detector (TBWD). Following the scran, two safety relief valves (SRVs) opened to control the resulting reactor pressure increase. Also, due to tripping of the feed pumps, Reactor Core Isolation Cooling (RCIC) and High Pressure Coolant Injection (HPCI) injected water into the vessel to restore level. The HPCI injection was menentary and was secured by an operator prior to reaching full flo An Unusual Event was declared at 7:15 p.m. and terminated at 7:16 p.m. due to the HPCI injectio ..

PSE&G determined the root cause of the reactor scram to be equipment failure in the trip mechanism. The TBWD is used weekly to obtain thrust bearing measurements. However, during the August 26 test a mechanical linkage, which normally prevents an actual turbine trip, malfunctioned and resulted in the tri Later evaluation determined that the mechanical linkage malfunction occurred due to a loose set screw on the shaft of a limit switch. The set screw was correctly repositione During the evaluation of the scram PSE&G determined that one of the two SRVs designed to respond to the pressure increase by opening electrically in advance of its mechanical actuation, i.e., a low-low set SRV, did not ope Further PSE&G review found that a component failure had occurred in the electrical opening circuit which prevented the SRV from receiving a signal to open. The failed component was replace Also, PSE&G found that the feed pump trips occurred due to a spurious indication of vessel level 8 because of level transmitter

"ringing", an indicated rapid amplitude oscillation in response to the pressure surge. The transmitter ringing indication was lower in amplitude than the ringing during previous scram Since corrective actions had been taken to control previous ringing, PSE&G is further evaluating the ringing indication to assess the previous corrective action The inspectors will review future licensee corrective action Further, PSE&G found that during the pressure transient, SRV M appeared to have opened below its setpoint, because SRV M's setpoint is 1108 + 11, -11 psi and the pressure surge peaked at 1088 psi. A safety evaluation concluded that given allowable instrument deviations, it was possible for SRV M to be working properly within its allowable setpoint toleranc However, the effects of a potentially lower setpoint on SRV M were evaluated and found to be acceptabl The inspectors reviewed the PSE&G post-tril: review, including Safety Evaluation 88-105 and the parameter traces from the GETARS computer. The review was thorough. Identified equipment problems were being resolved, and the plant was operated in an acceptable manne B. On July 19 Hope Creek declarei an Unusual Event and commenced a reactor shutdo,<n required by Technical Specification 3.0.3 due to both Main Steam Isolation Valve (MSIV) Sealing Systems being inoperabl The A MSIV Sealing System was out of service for scheduled maintenance on the associated Primary Containmpnt .

Instrument Gas (PCIG) compressor, and the B MSIV Sealini System

was declared inoperable when a pressure transmitter failed a channel check. The Unusual Event and power descent were terminated two hours later when a new pressure transmitter was installed and successfully tested. The reactor had decreased to 80% power and was returned to 100% power. (LER 88-17)

C. On August'15 routine valve stroke testing revealed that inadequate tagging control had occurred during a valve tagging evolution begun on May 27, 1988, which resulted in the inadvertent removal of power from the torus supply valve in the Containment Prepurge Cleanup System (CPCS). The inspector concluded that the personnel errors during this evolution represented a violation of plant system alignment control requirements (354/88-22-01).

Specifically, containment penetration P-23 (drywell purge exhaust) failed its May 27 leak test, and Technical Specification 3.6.3 action statement required that another valve be deactivated in the closed position or a blank flange be installed to isolate P23. PSE&G choose to do both in parallel, and the blank flange was installed within the four hour limit. However, in attempting to remove the relay for valve GS-HV-4952, the drywell purge isolation valve, the adjacent relay for valve GS-HV-4958, the CPCS torus supply valve, was erroneously removed. This error should have been corrected when the penetration was returned to service on May 30, but due to another personnel error, no effort was made to reinstall the rela These personnel errors occurred despite existing procedural guidance and are in violation of the requirement in 10 CFR 50, Appendix B, Criterion XIV, that measures be established fur indicating the operating status of components to prevent inadvertent operatio The safety significance of the above errors was minimal because the blank flange met the penetration isolation action statement, and the deactivated CPCS torus supply vaive was closed and is used only prior to deinerting primary containmen D. During the inspection period two intermediate runbacks occurred in the reactor recirculation system, which resulted from a testing error and from a component failure. The inspector reviewed the response of the equipment and the operators'

actions and concluded that these had been acceptabl On July 28, a partial C channel LOCA actuation and an intermediate recirculation runback occurred due to an improperly positioned mode switch on an ECCS logic tester during an I&C surveillance test. The partial LOCA actuation consisted of a start signal to the C diesel generator, C core spray pump, and the C diesel generator load sequencer. The C diesel load sequencer de-energized the C reactor feed pump's main lube oil pu p which tripped the C reactor feed pump before the auxiliary

.. ',

lube oil pump picked up. The ensuing level oscillation reduced reactor level to below 30 inches which caused the runback, thereby reducing reactor power to 70*4. The ECCS initiation logic was reset, and the unit returned to 100% power the same day. PSE&G plans to review the transition from the main to the auxiliary oil pump for possible improvemen On August 15, an intermediate recirculation runback occurred when a pressure switch failed in the control oil for the C reactor feed pump. This failed switch caused a spurious start of the auxiliary oil pump and the resulting pressure spike within the control oil system caused the feed pump turbine control valves to partially clos This closing resulted in an indication of a feed pump trip and a minor reactor level transient (greater than 5 inches below normal), which automatically ran back the recirculation system and resulted in reactor power being reduced t o 70*. . Power was returned to 100*. shortly af terwar Later, the failed pressure switch was replace The inspectors reviewed the impact of the unusually hot weather on the plant and co Pluded that there was no adverse impact on safety. Technical Specifications 3.7.1.3 permits continued reactor operation when Delaware River (ultimate heat sink) water temperature is 90.5 degrees F or lower. During the sustained hot weather, river temperatures reached 87 degrees F for portions of days. While this elevated temperature and the higher ambient air temperatures did reduce equipmen+.

efficiencies, including the cooling tower, the plant operation remained well within the design basi . RADIOLOGICAL CONTROLS (71709)

3.1 Inspection Activities PSE&G's corrpliance with the radiological protection program was verified on a periodic basi These inspection activities were conducted in accordance with NRC inspection procedure 7170 .2 Inspection Findings and Review of Events On July 23, a radiation protection technician identified two unlocked high radiation area doors while performing a routine shiftly check of locked high radiation area doors. For both doors the technician responded correctly by standing guard at the door until the door could be properly locked by shift personnel. A review of the key control log indicated that these two doors had been opened a shif t and a half earlier by an equiptnent operator to perform a weekly observation of the enclosed high radiation areas. Most high radiation area door locks (regardless of which direction you rotate the key) will

.. ,

allow entry and automatically relock when shut. However, depending on the direction of key rotation, some door locks provide an additional characteristic which disables the automatic relock feature and leaves the door unlocked. To enable the automatic relock feature on this type of door, the key must be reinserted and rotated in the opposite directio The two doors which were found unlocked were of this latter lock design. Station Administrative Procedure SA-AP.ZZ-024 allows trained equipment operators to monitor themselves to ensure the high radiation area doors are locked after their exit. After reviewing the event, the Radiological Protection Department implemented the following corrective actions:

-

A review of dose summaries by self-reading pocket dosimeter for the day the high radiation doors were unlocked indicated no abnormalitie The particular equipment operator who failed to lock the two high radiation door had his self-monitoring privileges rescinded pending additional trainin A double independent verification of locked status for any high radiation area doors which are unlocked was implemented with required documentation in the Radiation Protection Shift Lo The individual performing the shiftly check of high radiation area doors will be personally accountable for performance and docu vntation of this tas The resident inspector reviewed the event and the high radiation area key control system, and found the corrective actions acceptabl The failure to maintain these two high radiation area doors locked is a licensee identified violation (354/83-22-0?)

,

of Technical Specification 6.12.2, which is not being cited based upon meeting the criteria of 10 CFR 2 Appendix The inspectors will continue to review the adequacy of locked high radiation door control in future inspection (LER 83-20)

B. On July 13, the Chemistry Department violated the Technical Specificaticns, in that radioactive liquid waste was released to the river without a required sample (input to the monthly composite sample) having been obtaine The composite sample is made up of individual samples taken on each discharge to the river with the sample volume proportional to the liquid releas The discharge on July 13 was originally requested and sampled as a discharge to the condensate storage tank (CST). However, when equipment failure prevented the Chemistry Department frem

'

completing all required analyses, the discharge was changed and released to the river. The composite sample, which is not required on a discharge to the CST, was not obtained prior to the river release. This licensee identified violation is not being cited based on meeting the criteria of 10 CFR 2 Appendix C (354/88-22-03). As corrective action, technician training was conducted and a change to the radioactive liquid release request form has been initiated, which requires a sufficient sample size to perform all analyses regardless of the ultimate release destination. The inspector concluded that the corrective actions for the missed sample were appropriate and acceptabl During a semiannual radiological sealed source inventory conducted by PSE&G, some difficulty was encountered locating two Intermediate Range Monitors (IRMs). Eventually, PSE&G determined that the IRMs were stored in locked, controlled areas and were indicated on the radiological source accountability record. One problem identified during the audit was that several technicians conducting the audit were not clear as to the exact description of the IRM detectors. The Radiation Protection Department also identified some weaknesses in the control of IRMs and Source Range Monitors (SRMs) and initiated the following immediate corrective actions:

--

All new IRMs/SRMs currently stored in the 137' Turbine Building were banded together in the original shipping crates, lo:ked and labeled with serial number All IRMs currently stored in the gamma scan room were placed inside a tool box, locked and labeled with serial number A Work Order was written to install a locking cage to provide a service location for storage of new IRMs/SRM PSE&G plans to implement the following corrective actions by October 1, 1938:

--

Irradiated IRMs located in the gamma scan room will be I shipped as radsaste.

I --

On-the-job training will be provided to all Radiation Protection personnel on identification, control, and storage of IRW /SRM i

--

The source a: countability procedure will be rivised to include specific steps in dispositioning of used, irradiated IRMs/SRMs.

In addition, future contractor training courses will include training on control of IRMs/SRM The inspector reviewed the Radiation Protection Department's accountability procedures, corrective actions, and several radioactive storage areas. The inspector concluded the corrective actions were adequate and acceptabl The inspector reviewed the testing associated with the solid radiological waste handling equipment, including a tour of the asphalt processing ro,ms. The inspector observed the tests of a steel drum of pre essed asphalt, which met the test acceptance criteria, having no free water and less than 15%

shrinkag (Closed) Inspector Follow Item 65-44-11: Various ALARA and human f actor concerns in the radwaste control room and the resin regeneration and transfer room (RRTR). Since this item was opened, Hope Creek has altered its resin management philosophy, which has negated the inspector's original concerns. Hope Creek now discards rather than regenerating its deep bed polisher resins. Transfer of polisher resins via the resin transfer line, which would have normally occurrec for regeneration on a daily basis, now occurs once per month for resin transfer and storag This drastically reduces the radiation levels on the specified pipe and valve. The inspector verified that the RRTR general area and contact readings on the valve were both approximately 1 j millirem / hou In addition, all resin transfer (which would

'

increase radiation levels) are performed remotely tnd require no operator entry into the RRTR. The valve specified in the open item is not operated during normal operation, and no major maintenance on this valve is anticipated. The inspector evaluated the dose rates near the specified pipe and valve and found them to be acceptabl The inspector verified that the radwaste control room had proper lighting and noise control, and that mislabelling of the liquid flow paths had been corrected.

/. PSE&G found that three of the six Filtration, Recirculation, and Ventilation System (FRVS) recirculation units had vibration induced fatigue cracks in the internal vanes and surrounding duct wall in the transition duct between the supply fans and the downstream filters. The inspector reviewed Design Change Package 4HM-0397, which repaired the cracked vanes and ducts and stiffened the vanes, and observed the inspection and repair of 2 the three FRVS units. The inspector found the design change and its implementation acceptabl However, it became apparent to the inspector that three FRVS

units had previously been repaired for similar vibration induced cracks beginning in December 1987. The remaining three FRVS units had been verified to be crack free dur i ng this cerio In discussions with plant engineering management, Abe inspector was

, informed that folicwing the repairs of the initial three units, further repairs were held in abeyance pending engineering evaluations of an improved design. However, the work on the

improved design was postponed based on higher priority work.

j The inspector concluded that the continued operation of the

'

three unrepaired FRVS with the high potential for degraded l equipment conditions appeared to represent poor management of an

'

unresolved engineering issue. NRC review of other unresolved engineering issues to better assess their priorities will be performed. (LER 88-21) The inspector selected two temporary modifications (88-033 and-034) and reviewed the safety evaluations. The inspector found
