REPORT WEEK STARTING:
06 13 88 PAGE QF Five MOS Observers were on shift.
Richard Coulthard, Westinghouse Electric Corporation (06/13-19/88, days);
Peter L.
- Walker, Westinghouse
- Electric Corporation (06/13-19/88, evenings);
Julio C.
Balaguero, Turkey Point Nuclear Plant Operations Support Supervisor (06/14-19/88, evenings);
and Larry L.
- Thomas, Turkey Point Nuclear Plant Outage Manager (06/13-19/88, evenings);
and Terry A
- Finn, Turkey Point Training Department Superintendent (06/19-20/88, evenings).
Both Units 3
and 4
operated at 1004 power throughout the reporting period, except for a Unit 3 reduction to 690 MWe gross for approximately 8
hours on June 15,
- 1988, to replace the generator air side seal oil pump.
Two questionable work practices were reported by the MOS Observers concerning noncompliances with the clearance tag procedure.
One questionable work practice was reported concerning delay in reporting malfunctioning equipment to the Plant Supervisor Nuclear.
During the reporting period, the MOS Observers noted seventeen recommendations and areas for improvement.
These comments and suggestions involved:
The inability of the Moveable Incore Detector System to support flux mapping (repaired 6/19/88).
Two comments on inadequate communications between departments causing unnecessary delay.
The unreliability of two radiation detectors.
Operators lack of familiarity with the Technical Specification Implementation Procedure.
Two comments regarding the perceived need to run flux maps.

SUMMARY
, REPORT WEEK STARTING:
PAGE OF Two comments on the reliability of the inverter power supply to the Analog Rod Position Indication (ARPI).
A suggested relaxation of the ARPI rod bottom runback bistable setpoint.
The advisability of energized receipt inspections on certain I&C equipment.
A recommended reordering of work under an LCO, for efficiency.
Four comments on inadequate planning or scheduling.
During the reporting period the Plant Supervisor-Nuclear (PSN)
MOS reporting program continued.
In recognition that the PSN is in fact Management on Shift, the form used by the PSNs has been retitled "Shift Report,"
with the Shift Management personnel identified.
The PSNs reported nine questionable work practices.
Two of these were also reported by MOS Observers (clearance tag violation and delayed report of malfunctioning
, equipment).
Two others concerned inadequate support outside normal hours.
The remaining items involved:
Opefation with a Reactor Protection channel out-of-service.
(For an extended period within the LCO).
Insufficient emphasis on LCO related repairs.
Unauthorized manipulation of equipment by Maintenance personnel.
(Fire Protection pressure switch in Turbine Building)
Confusion on requirements for testing of redundant train equipment prior to maintenance.
Attempted use of an out-of-date. maintenance procedure.

At 1740 the peak shift 1 6 C Supervisor was asked by the MOS Observer if he realized Unit 3 was in an action statement, per O-ADM-021, which ends at 2340.
He said he had not been informed.
Once he found out he took the appropriate actions to get the PAVO ready and work accomplished.
The Flux Map should have been started sooner.
Various problems encountered caused it to be completed 27 minutes after the required time of 2340.

Instrumentation and Control department had six hours, 55 minutes (minus approx.
15 minutes to perform operability check) to repair the offending Power Range Channel.
It was returned to service too late to avoid overrunning the 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> LCO time.
Directions to the technicians performing the repair lacked the emphasis required to ensure that the job would be completed on time.
Reactor Engineering did not include any contingency time when they scheduled the start of the QPTR Flux Map.
Problems arose which prevented them from supporting the required 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> action limit.
The operation staffs did not have a crystal clear idea of what was to happen when. the 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> limit was reached.
There were three paths to success:
Fix the channel; get acceptable QPTR results; or obtain a waiver of the applicable 0-ADM-021 Interim Technical Specification.
A fourth path, reducing power to 75",0 and reducing power range setpoints, was out of the question due to being procedurally impossible, given that one channel was already failed.
When the shift was turned over, many options were already precluded, and the oncoming crew was jammed into a crisis situation.
Proper planning would have already resolved any interpretation of Technical Specification questions, have had a
pre-authorized waiver of 0-ADM-21 Technical Specifications available, had enough information available to adequately supervise supporting group actions, and have a definite plan of what was to occur when the action statement time expired.
Professionalism, Summary of Shift, Comments Question:
Why, when a perfectly valid method of determining QPTR via the 3
operable power range NIS channels
- exists, is the 0-ADM-021 Technical Specification worded to require the use of the much more cumbersome (albeit more accurate) flux mapping method?

Questionable Work Practices/Actions Taken/Recommendations At 1140 6/13/88, N-41 was declared out-of-service for calibration and testing.
At 1645 N-41 failed its periodic test and a PWO was issued.
Maintenance was not started until late on peak shift - Reactor Engineering did not perform Flux Map untii 2025 and did not get it complete until 0007 6/14/88, which was greater than 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> requirement per ADM-021. It doesn't seem the correct effort was placed on getting N-41 repaired when a 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> action statement was in effect.
Areas for Improvement/Recommendations/Actions Taken If a Power Range Channel is out-of-service greater than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> perform Flux Map to ensure it is complete within the required time frame.
Investigage changing ADM-021 requirement for a Flux Map to verify OPTR values, to perform QPTR calculation per ONOP 12308.2.
If it is expected that maintenance will go beyond 4PM, formulate a game plan with contingencies.
ADM-021 Table 3.3-1 action 2C, reducing power to less than or equal to 75'.b and reduce hi flux trip to less than or equal to 85',o is not a possible option due to minimum degree of redundancy with one channel in trip mode (out-of-service), removing another channel to reset trip setpoints will cause a reactor trip.
Therefore flux map, or returning channel to service is the only option.

This problem came to the attention of the day shift APSN during the course of his duties and resulting actions are discussed in the PSN shift report.
It is felt that the APSN responded properly to this event.
The requirement that all clearance tags not be violated is presumably is well known. 'Operations and shift management should re-emphasize to all personnel the importance of not violating clearance tags.

Immediate safety problems None Questionable work practices Checked the clearance on the 4A Component Cooling Water (CCW) Heat Exchanger and found a clearance tag for vent valve 4-50-585 hung on valve 4-50-375A which is,a redundant vent valve on the same heat exchanger.
Notified the PSN (peakshift) who immediately took corrective action and had the tag hung on the correct valve.
D.
Areas for improvement Strict adherence to procedural requirements shall be reiterated to all operators so that clearance orders are followed verbatim.
Operators have a difficult time isolating CCW Heat Exchangers after scaffolding has been erected because of limited space.
Realizing that the amount of time on LCO's should be limited, it might be a good compromise to isolate the heat exchanger first and erect the scaffolding
- second, while the heat exchanger is being drained.
This should make it easier to operators to isolate the heat exchanger and allow Maintenance plenty of time to erect the scaffolding, especially if we drain the side of the heat exchanger that is not being opened.

Questionable Work Practices/Actions Taken/Recommendations None B.
Areas for Improvement/Recommendations/Actions Taken Need a better method to couple the Main Feedwater Regulator valves to their actuators.
In the past two years we have had at least 2 load reductions to 60 Megawatts electric, due to the presently installed "split couplings,"
loosening up from vibration and causing valve shaft actuator separation.
Tonight we almost had the same situation, however the coupling had only slightly loosened and the actuator and valve stem threads didn't have a chance to misalign.
Recommendations:
Better method to lock coupling together or re-design the coupling mechanism.
C.
Good Practices/Professionalism Observed Excellent support from IGC and Mechanical Maintenance to immediately focus their efforts on 4A Main Feedwater Regulator loose coupling.
They were on the scene approximately 3 minutes from my notification of the problem.

gray area.
Current Technical Specifications definition 1.4 defined operability which states that any ESF equipment plus its support functions must be operable and capable of performing its design functions.
We are currently receiving clearance requests on ESF equipment support equipment.
Examples being:
A.
Residual Heat Removal pump 3A-PC-3-601.
This is a pressure interlock on 3A RHR Loop which when valved out will take 3A RHR Loop out-of-service.
Compliance and Regulation reply was to test this PC-3-600 on 3B RHR pump.
To test this will involve valving out PC-3-600 which will take 3B RHR Looo out-of-service.
Containment Spray Pumps (C.S.P.)
3A and 3B must have their seal cooler floe indicators (FIC-657 and FIC-659) P.M.'d one at a time.
This involves racking out the associated C.S.P.
This means that a surveillance operability test will be required on the companion pump prior to maintenance activities.
If either of the above examples were to occur on any shift other than dayshift (Monday
- Friday) and it was due to a discovered failure of the support component, Operations personnel would not be able to meet the redundant train required test within the specified 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> time limit thus non-compliance to a Tech.
Spec.
action statement per licensing letter.
Recommendations:
1.
Re-evaluate PTN-TECH-88-288 letter. Contact USNRC and discuss problem to arrive at a solid answer of how to meet redundant train operability requirements in the cases of Preventive Maintenance, etc. on support equipment.
2.
Evaluate the need for special procedures to utilize (by on-site operators) for operability testing of ESF equipment.
tNote:
Many of our test'rocedures are performed by the Technical Department with Operations support.
3.
Prior to sending clearance requests to the Control Room'on ESF type equipment, ensure that Technical Department is set up to test the redundant train if required.
lf not required, have responsible department supervisor sign and state that "no t"sti:
required" on redundant train.

Excellent observation by Nuclear Watch Engineer (NWE);
informed PSN that while removing fuse block SV-6428 (Reactor Coolant System sample) his hand slammed into the Reactor Trip Switch casing and 'connectors behind Vertical Panel B.
The PSN observed this and verified the same condition exists on Unit 4 on fuses for CV-956 A. This occurrence is nearly unpreventable due to close proximity of fuse blocks to Reactor Trip Switch.
NWE placed caution tags on both fuse blocks.
This could cause unit trip.

Areas for improvement During the morning, confusion surfaced over controls on moving a large crane from the Unit 4 containment to the Unit 3 containment during which the load must pass oyer Intake Cooling IVater lines and safety-related cable trenches.
There was also conflicting information over the weight of the crane; initially reported at 240,000 lbs., but later reported to be below the 165,000 lbs. limit for this move.
If movements of this size are very infrequent (less than annually), action such as revising ONOP 3408.2.
Intake Cooling Iyater Failure Due To Transport of Heavy Loads, or a notice in the Control Room shift order book, are not appropriate.
If frequency of occurrence is greater, some guidance for the Control Room to evaluate and monitor this type of event might expedite future movements.
Operations was correct to look for guidance on this issue because of regulatory sensitivity to heavy loads.
0-A0 M-019 Management on Shift (MOS)
MOS DAILYREPORT The conduct of 3-PM-028.2 resulted, in a loss of all.power to the Rod Position.lridicators (RPI) for several minutes (i.e., all rods were indicated on bottom).
The conduct of this test raises two concerns:
a) Because of fluctuations in the RPI inverter power supply, the power supply for the RPI's is always switched to the Emergency Power Supply (a lighting panel) for this test in order to get steady-stare data.
Is there a reason the inverter power supply cannot be repaired or restored so these fluxuations do not exist?
b) During the conduct of this test, the Rod Bottom Bistable alarm setpoint is verified and reset if not in tolerance.
These bistables chatter during this process which reduces bistable life.
Since this has been done monthly for some time, there is no reason to suggest this caused the lighting panel to trip.
However, the acceptance criteria for resetting this alarm is 0.209 to 0.310 Volts D.C.
(less than
+
I step).
A +
10 step tolerance on the rod bottom alarm is probably acceptable since it has only an information/condition indication function and is not a calculated setpoint.
It is quite possible this alarm would have to be reset less often (with less tine spent with a chattering relay) if the tolerance were opened to something like 0.15 to 0.45 Volts D.C.
Professionalism, Summary of Shift, Comments 2.
3.
The Operations response to the loss of power of the Unit 3 Rod Position Indicators was carried out in an organized and timely manner.
OP-9700.2, Operation of RPI Power Supply System was used to transfer power from the Lighting Panel back to the RPI Inverters.
The Off-Normal Operating Procedure was pulled out ln case the above action did not solve the problem.
Shift turnover was in progress when this occurred.
I witnessed and concur with the PSN day shift report concerning the desire of an IGC Specialist to use an out-of-date procedure, I consider the overall incident a "good practice" because it demonstrates the Control Room review of On-The-Spot-Changes can prevent out-of-date procedures going to the field for use.
About 1700 on the peak shift, the Licensing Engineer brought a letter concerning testing requirements for Emergency Diesels to the Control Room.
He took the time to review the contents of the letter with the PSN and APSN.
A good practice, especially for a late Friday afternoon.

The IGC technician was very informative and gave the Reactor Operator a thorough explanation in a very professional manner.
Shift meeting in the midnight shift continues to be excellent.
The APSN and PSN encourage open communication and insist on getting good feedback on plant problems.
The use of the Plan of the Shift form is a very good idea.
This form gets filled out by the APSN or PSN and distributed to everyone in the shift meeting to serve as an agenda and keep the meeting on track.

Areas for Improvement/Recommendations/Actions Taken The Post Accident Hydrogen Monitor (PAHM) is required to be in service 30 minutes after a valid Safety Injection 'Signal.
Every time we attempt to test PAFIM's for a monthly surveillance, either one or both channels fail to meet acceptance criteria.
The support to have this problem repaired usually appears close to the end of the required LCO time, i.e., 7 days or 30 days.
The problem appears generally with the span check in which IGC calibrates,

Areas for Improvement/Recommendations/Actions Taken It was noticed by the midshift APSN that the Unit 4 Containment purge valve data sheet in our Redbook Surveillances indicated that valve POV-4-2603 had not been tested prior to exceeding 200', during past outage.
There was no data in our Control Room to prove or disprove the operability concern.
The dayshift PSN/APSN followed up on this concern and solicited Technical Department support to find the test data sheets proving operability.
Actions taken were to update the data sheet with proper information and transmit old data sheets to Document Control.
Recommendations:
Note:
The PSN is responsible for review of O-OSP-200.1 (Redbook Surveillances).
The PSN is responsible for review of the RCO logs.
Make the Containment Purge Valve Cycle Data Sheet Checkoff, a PSN surveillance check per O-OSP-200.1 on a monthly basis in Modes 1,2 and a daily check in Modes 3,4,5,6.
Make the Startup Surveillance O-OSP-200.2 reflect a Technical Departmemt Signoff (TDS) to ensure prior to Mode 4 during heat up; they review 3/4-OSP-201.1 attachment 5 and update cycle data sheets in accordance with current number of cycles, remove old sheets in book and transmit them to Document Control.
Note:
Tracking of actual Local Leakrate Test (LLRT) status and tracking of valve cycles

Metal Impact hionitoring system (MIMS). At this time Unit 3 MIMS has been out-of-service since 3/04/88, and Unit 4 MIMS'since 6/11/88. It is presently impossible to perform the mid-shift check for noise.
Recommendations:
Repair this system, it could be a valuable tool. (See attached comments).

Good Practices/Professionalism Observed 2.
SRO candidate requested a PSN tour of plant as to enhance his knowledge of plant systems.
He asked many questions and showed to me that he has indeed studied the systems in depth.
Good work, BillLindsey.
Unit 3 NTO, (Fred Bennykofer) while making his rounds observed cloudy oil in the "A" Auxiliary Feedwater pump oil reservoir.
His only requirement is to record level in sight glass.
When I checked the situation it was obvious he stuck his head in the pipes to make this observation.
Actions:
Declared 3A Auxiliary Feedwater pump out-of-service and issued PWO to change oil.

MIMS SRO, Joe Scott initiated this list at PSN re uest.
Operator hardspots - the system is outside the unit operator surveillance area.
Due to its location it's often forgotten about.
When an alarm is received by the unit operator, he has to find someone to investigate it for him.
This may include running the tape for 10 minutes.
The system often gives false alarms, has tape
- problems, etc.
Currently the machine has nowhere to hang the microphone so it hangs on the recorder power leads.
Suggestions for improving MIMS:
1) 2)
3) 4)
Write operators a surveillance procedure.
Move the unit operators surveillance boundries to include the MIMS rack.
Present a MIMS lecture in requal including use ot the tape machine.
Increase IGC surveillance for PM's.
