Four MOS observers were on shift:
Lamar L.
McLaughlin,. St.
Lucie Plant (01/11-17/88, Days);
Peter L. Walker, Westinghouse Electric Corporation (01/11-18/88, Nights);
Lee 'C.
Huenniger, Turkey Point Startup Department Superintendent (01/11-16/88, Split) and Jesus
- Arias, Turkey Point Regulation and Compliance Supervisor (01/16-18/88, Split).
While on shift these MOS observers reported potential safety
- problems, questionable work practices, areas for improvement,
- comments, and general recommendations.
During this reporting period Unit 4 remained at full power except for routine main turbine valve operability and turbine trip tests.
Unit 3 was ramped to full power but had to be shutdown to Hot Standby (Mode 3) because of an unretrievable dropped rod (two rods were dropped during the attempt to retrieve the initial dropped rod).
A Control Rod Drive Mechanism (CRDM) housing seal weld leak was identified.
Unit 3
was cooled down to cold shutdown (Mode 5) in order to effect repairs.
No immediate safety problems were observed.
The following questionable work practices were observed:
During maintehance on the "3B" Boric Acid Transfer Pump the strip heaters were not deenergized (not on the clearance) which was a potential shock/burn hazard.
Security guards were observed to key their radios in restricted areas (may have caused some spurious alarms).
This requirement will be reviewed with all security personnel.
Some improvements were recommended by the MOS observers:
Affix lights or fencing around the Hydrogen trailer by the Unit 1
& 2 discharge.
Update phone numbers on security signs and replace any that are missing.
Review the processing of Plant Work Orders (PWOs) in order to improve the system.

MOS DAILYREPORT Page Professionalism, Summary of Shift, Comments The Nitrogen backup system for the Main Steam Isolation Valves appears to have problems that make the system difficult to operate.
The primary problem is leakage out of the system and check valve leakage.
These problems manifest themselves as excessive bottle changing and Temporary System Alterations to Surveillance Test procedures.
Recommendations will be made after further discussion with appropriate plant and engineering personnel.
A review of Nitrogen usage will be done tf data exists.

- can't be shut off with faucet - water is in short supply - Plant Work Order was written last night.
The Hydrogen trailer by I 6 2 discharge has no lights under or fencing around it.
Suggest a light be permanently affixed to the nearby station for meeting this requirement.
Professionalism, Summary of Shift, Comments An NRC letter dated December 22, 1987 was read by the PSN at the shift turnover meeting in the Control Room.'his letter dealt with formal communications and led to a heated discussion between operators and the PSN.
This letter stirred much resentment and created a negative effect by people who have been under the gun for a long time and the resulting stress it carries with it.
This correspondence needed to be more specific, not such a sweeping statement of condemnation.
Attached - the Nuclear Newsletter under regulatory matters

- Operators're no longer having difficulty maintaining nitrogen bottle pressure.
- The Nitrogen System valves for the MSIVs are leaking such that additional isolation is required to perform periodic testing (See OTSC 5656).
- Technical is considering adding the MSIV Nitrogen System to the scope of the Request for Engineering Assistance (REA) for the Auxiliary Feedwater System (AFW) Nitrogen System work.
Control Room operators are attempting to clear past due surveillances.

I observed three Operations/Maintenance turnovers in the Control Room during the past two days.
Each Maintenance Department representative had in hand the Plan of the Day.
Z.
Two in-shop turnovers were conducted in which on going work activities and the Plan of the Day were passed on to the on-coming shift. All the supervisors and foreman I talked to expressed a feeling of having a
better status of plant needs.
They thought having Maintenance at the Operations/Maintenance turnover meetings gave them an update to the current operations needs.
3.
A general feeling I got was the Maintenance people were providing better operations support than my previous Management on Shift days.
This was observed by two foreman receiving operations calls during our conversation, excusing themselves, then directing their people on a real time basks to take care of the operations needs.
Their attitute was more suportfve and a willingness to do so.
4 The peak shift with mid shift holdover, did a very professional job of bringing down the unit, coordinating the valve test, taking out the reactor trip breaker for IGC relay replacement, performing the Turbine Trip Test and increasing to full power operation.
Recommendations The water cooler on the turbine deck by ¹3 generator exciter switch gear is rusted out and tied to the rail by a rope. It should be replaced or removed, it gives a run down appearance to a very visible area.

Professionalism, Summary of Shift, Comments RCS pressure reduction After the shift turnover meeting (7:45) I noticed an unusual trend on pressurizer
- pressure, (approximately 350 PSI drop in 12 minutes, then increase).
This decrease had happened on the previous shift (about 7:15 a.m.) and was stored on Safety Assessment System (SAS).'hecked cooldown procedure to see where the accumulators should be isolated (700 to 1000 PSI) from RCO to see if there were any pressure/temperature problems.
No problem found.
Notified APSN and PSN to ensure they were aware of the event.
Requested a pressurizer level trend to see if accumulators had injected into RCS.
Information was not conclusive, subsequently received accumulator trends that appear to show discharge to the RCS.

The fire team responded quickly - had appropriate gear, worked well with all departments involved.
This was a small, but not normal situation in that a trace of smoke was coming from a conduit in a open manhole.
Thermography was used to locate covered
- manhole, Construction/Plant forces opened manhole - fire team lead way to determining source.
Operation personnel assisted in isolation of the feed, once the probable feed was indentified.
Plant Electrical forces willsecure source and render it safe.
2.
One problem was identified from the fire in the manhole.
Once source of supply was properly identified, the breaker could not be opened to confirm suspicion due to a
lock on distribultion center door.
Considerable time was expended until a
key was found and lock removed.
3.
The peak maintenance crews had a
good work plan for the shift.
They accomplished the polar crane mechanical
- checkout, moved the missile shields to the top of the pressurizer, defeated the personnel hatch inte~ locks and opened equipment hatch.
A real good effort.
h Recommendations (See E. 2.)
All panels,
- breakers, buildings should have a
key for entry at a
centralized location such that entry could be made without cutting locks or destroying doors.
I suggest a key storage facility be maintained at a central location and keys identified. by panel or building location.
A place that is manned 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day and controlled such as security, might be a good group to act as custodian.
(See D.)
A meeting of Operations
- Planner, Scheduling, Maintenance, Generating Equipment Management Systems (GEMS),
and OC representative meet to coordinate details.
The basics are in place, a couple of people I talked to have ideas for improvement.
- Proceduralize outcome of meeting by incorporating a
standard method for all shifts to follow.
- Example, 0-ADM-010 activity planning and coordination, hot items (the subject) is already there
- needs expansion and more direction/detail.
- Provide PSN, APSN, and NWE computer training or detailed menu to follow. (PWO inputing).
- Provide how backup method will flow should computer system fail.
(Manual on similar method needs to be established and documented).
The R-14 PWO of 01/14/88 took aproximately six hours to get to the field from origination.
Numerous small items that collectively used too much time and can be improved on by the ideas of those I talked to should be
- utilized.

Area(s) f'r improvement Logging of RCS pressure event
- This event should have been logged in the RCO log.
An entry such as "RCS pressure transient occurred.
RCS pressure recovered.
Investigating."
would have been appropriate.
It is not my intent that every annunciator have a log entry, but I do feel a description of a
~si nificant transient like this should be entered even if the root cause is not known.
Professionalism, Summary of Shift, Comments RCS Pressure reduction event.
- Discussed the event with the off-going RCO.
He took accountability for initiation of the event.
The root cause appears to be an error in the adjustment of the spray valve just before or during the shift turnover.
The spray valve in use had a plant work order written against it due to valve response characteristics.
The shift turnover was in progress.
These two factors probably contributed in making this event occur.
- Discussed with the operators the logging of an event like this.
Early entries were not made although subsequent entries were made in the APSN log. This item is identified as an area for improvement.
- Reviewed the Shift Technical Advisor (STA) report of abnormal occurrences and determined that the first indication that a problem existed was the accumulator alarm actuations (RCO statement).
These alarms show that accumulator discharge had occurred.
The operator took manual control of pressurizer spray and ensured heaters were energized to recover pressure.

MOS DAILYREPORT Page Recommendations Recommend that this event be reviewed by other operators via routine in-house review system.
This event could have been more complicated had the accumulators been isolated at initiation.
Recommend that Operations Department address the event logging area for improvement.
It is not clear who should have logged this event considering time of the event (shift turnover).
Repair PCV-455B at first opportunity.

brea(s) for improvement IGC Technician came over to the Control Room to work on relay TC-4-408D-I.
Upon questioning by Control Room personnel and Shift Technical Advisor (STA) of possible effects of his work, he could not answer.
He was asked to go back to the shop and get more familiar with the work planned and possible effects.
He then came back (approximately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> later) and had a good understanding of the relay function and effects of his work.
"4Cn Charging Pump was discussed at the 1:00 p.m. meeting as needing further work (could not hold a 45 gpm orifice) but this work was not turned over to peak shift or mid shift in Mechanical Maintenance.
With the "4B" Charging Pump having an information tag to minimize use, the n4C" Charging Pump work becomes critical.

MOS DAILYREPORT Page Professionalism, Summary of Shift, Comments Overall, professionalism was adequate.
Shift briefings are thorough and well attended.
Some inform'ality still is noticed during shift briefings.
During the shifts there were several trainees in the Control Room.
RCOs and APSNs had good control of them.
During the peak shift, I witnessed the task of placing CV-4-1510A back in service.
There was good coordination, valving was done carefully and prudently.
Adequate supervision was devoted to this evolution.
Constant communications between Unit 4 RCO and other personnel (PSN, NWE, and TOs) was efficient.
A difficult evolution was handled smoothly.
Shift briefings are not necessarily following the Daily Work List.
Recommendations 16C personnel should be knowledgeable of work and its effects.
A few more minutes at the shop'will expedite the work and prevent mistakes.
Review Daily Work List during shift briefings for work scheduled for the shift. (Priorities may change).
Operations management should review the pressurizer pressure transient of 01/15/88.
What was known
- then, may be important.
Did not get a clear description of root cause.

Old drawing update trailer located east of the Technical Support Center has a section of chicken wire removed, and no lighting has been installed underneath.
In reviewing the Out of Service log, found an Appendix B sheet for testing of 3-2833 (Auxiliary Feed Water flow control valve).
This sheet is required by procedure to be signed off by the Inservice Testing Coordinator or the Shift Technical Advisor upon completion of post-maintenance testing arid provided to the Maintenance Supervisor for signature.
FCV-3-2833 was placed in service during the day shift after satisfactory testing per 3-OSP-75.10.
The Appendix B sheet was not signed off or pulled out accordingly.
