MANAMENT ON SHIFT (IOTAS)

WEEKLY

SUMMARY

REPORT STARTING.

3/28/88 PAGE I

OF 1

Four MOS Observers were on shift; Daniel H.

West, St.

Peter L.

Walker, Westinghouse Electric Corporation (03/28-04/04/88, nights),

D.

W.

Haase, Turkey Point Nuclear Plant Safety Engineering Group Chairman (03/28-30/88, nights),

and Daryle L.

Osborn, Turkey Point Nuclear Plant Configuration Manager (03/31-04/04/88, nights).

During the reporting period, Unit 4 operated at 100% power.

Unit 3 xeturned to 100% power on March 31, 1988 after the repair of a Unit 3 Condenser Tube leak.

No immediate safety problems were identified during the reporting period.

One questionable work practice was identified concerning a misaligned valve in the Auxiliary Feedwater Nitrogen Backup System for Unit 3.

The misaligned valve did not affect the operability of the system.

During the reporting

period, the MOS Observers noted eleven recommendations or areas for improvements.

These comments and suggestions included:

Three comments were made concerning administrative items associated with control of operational procedures in the PSN files, proper inventory control of spare paxts and I

& C testing of components prior to release to operations.

Two comments were made concerning priority of maintenance work associated with the Nitrogen Backup System to the Main Steam Isolation Valves and Intake Cooling Water System strainer cleaning.

Two comments were made concerning housekeeping practices associated with sandblasting and cleanliness near the Unit 3

steam jet Air, Ejector.

Four miscellaneous comments were made associated with the tightness of the Unit 3 6A and 6B Feedwater Heater anchor bolts, strainer cleaning procedures, two missing tags on the Backup Nitrogen System for the Auxiliary Feedwater System flow contxol valves and precautions associated with placing a

steam jet air ejector in service.

Valve 3-40-1617 (Train I) was found to be in a noncomplying position and immediately reported to the FSN.

The valve's position was subsequently determined to be inappropriate, and was repositioned by a Turbine Operator and a licensed Senior Reactor Operator.

The valve is currently properly

aligned, and system operability was never compromised.

The valve's position was previously checked on day shift on Friday, March 25,

1988, when 3-OP-65.2 was performed on Train 1 of Nitrogen Backup System to Auxiliary Peedwater System.

Unit 4:

Immediate safety problems None C.

Questionable work practices During performance of 3-OP-65.2 (Train 1), valve 1-3-40-1617 was improperly signed off as being in the proper position.

An investigation as to the cause of this nonconformance is currently underway.

Train 1 of the system had been aligned in accordance with 3-OP-065.2 on March Z5, 1988.

An investigation needs to be done to determine the cause of the valve being in the incorrect position.

This will be followed up on my next shift.

D.

Area(s) for improvement Completed copies of portions of selected operating procedures are required to be retained in the PSN's file until the next performance of that proceduie.

However, when the file was accessed to obtain a copy of 3-OP-065.2 which was performed for Train 1 on March 25, 1988, all that was found was a copy of 3-OSP-065.2 performed on March 28, 1988 for Train 2.

Thus, if only a portion of a procedure is done on a given date, it is likely that the "old" procedure in the file will be discarded.

The practice of filing the procedure for reference needs to be improved so that the most recent status of all portions of the procedure are available.

Professionalism, Summary of Shift, Comments 2.

3.

Much was accomplished

tonight, in an efficient, professional manner.

A lot of valuable training for license candidates was conducted.

The Control Room was crowded at times, but was orderly and well-controlled.

Last night, I promised to investigate the root causes of the nonconforming Nitrogen Header Pressure Indicator Root Valve, and the lack of cooling fans for Unit 3's Startup Transformer.

I got assurance that R. Mende was investigating the nonconformance issue.

I was told that operation/maintenance of the fans falls in to the Transmission and Distribution Group.

The breaker for the fans was reset and reclosed, but the Transmission and Distribution Group is not going to pursue it any further.

No one in Operations takes logs or ensures fan operation, and no one could tell how long the fans had been out of service.

Recommendations 1,

During an alignment check on the Auxiliary Peedwater and Main Steam Isolation Valve Backup Nitrogen Gas Supply System using 3-OP-065.2, two valve identifying tags (3-40-1673 and 3-40-1674) were observed to be destroyed (melted) and should be replaced.

This is a sensitive system and operator confusion factors should be kept to a minimum.

2.

During alignment of the Condenser Air Ejector for operation, a large column of hot water was ejected from the exhaust

stack, forcing the Turbine Operators to scramble out of the way. I am told that this happens frequently, and it looked to me to be something of a safety hazard.

Perhaps a better way of placing the Ejector in service could be found, or a method of draining the water slug away prior to establishing full steam flow.

Area(s) for improvement PWO Tag No. 400878 was written on 3/24/88 for the cleaning of the 3A ICW strainer to the CCW Heat Exchanger in accordance with procedural requirements for failing to meet the differential pressure acceptance criteria following backwashing.

A Bl priority was established which iS less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to initiate the work.

As of the peak shift, 3/29/88, the strainer has not yet been cleaned nor has the high differential pressure (DP) been eliminated.

(It' probable that the DP indicator is reading high, because the DP on the 3B ICW strainer is about one psi lower).

Since strainer cleanliness can affect operability of the ICW system, the priority established by operations is appropriate and the FWO should have been worked or the high DP issue resolved within the required time period,

Professionalism, Summary of Shift, Comments The evolutions required to take Unit 3 critical and place it on the line were observed.

Reactor operator trainees were used at each position during these efforts; each backed up and instructed by an experienced Reactor Operator or Senior Reactor Operator.

For both of of these major evolutions, a

professional atmosphere was maintained.

Recommendations (Reference item D)

Assure that work required by PWO's that have identified operability concerns (thus assigned a high priority) be initiated within the required time period, or that dispositioning of the issue that caused the PWO be initiated within the same time period.

Smooth, relatively uneventful shift 2.

Over the past few days, I have noticed that extraneous noises over the plant page system are increasing in frequency compared to the past few months.

The PSN mentioned it during his shift briefings, and it helped to reduce the noises.

Recommendations IUhile looking over the secondary plant, I noticed that Unit 3's Air Ejector area was

messy, relative to the rest of the plant.

Unit 4's Air Ejector area is being cleaned, so it may be that the Maintenance Department is just getting around to cleaning unit 3's Air Ejector area.

Specifically, I observed four valve wrenches hung on valves, a broom and dust pan lying around, loose brackets on wire conduit, rust on one of the 50 gallon drums and air lines loose and dirty.

Radiation monitor RM-15 is non functional following the release of water from the air ejector last night.

When the Unit 4

painting, enclosures were not used.

Thus grit from this operation was observed in various areas containing equipment such as the Seal Oil Pumps and Motors, the Main and Auxiliary Transformer, the voltage regulator cabinets, the Iso-phase Cooling System and the "4A" Motor Control Center.

More care should be used to prevent the sandblasting grit from getting into such areas.

2.

When the ICW strainer to the CCW Heat Exchangers is placed back in service following

cleaning, it may improve the entire cleaning effectiveness to perform a backwash operation prior to placing in service.

This could be accomplished by simply changing the valving sequence when releasing.

MOS DAILYREPORT Page Professionalism, Summary of Shift, Comments The peak-to-mid shift turnover for the IGC Maintenance Department was very professional with good verbal communication on work in progress and jobs required for the shift. The Plan of the Day was used during the turnover.

The 'peak-to-mid shift turnover for the Mechanical Maintenance Department was observed with the following items of strength noted:

Plans for work to be executed by the mid shift had been prepared and approved by the peak shift personnel.

Five jobs were planned for four workers on the midnight shift.and prioritized in accordance with the Plan-of-the-Day.

The work on the cleaning of the "3B" ICW strairter was well coordinated resulting in minimum time in an LCO condition.

Workers used safe work practices in performing the cleaning and in removing the rigging from the overhead following the cleaning.

The area was cleaned of all tools and equipment, and ladders were stowed in their proper place following the work.

Recommendations (From D-1)

Any sand blasting that is to be performed should be evaluated for the effect on the surrounding equipment and appropriate measures taken to prevent spread of sand blasting grit to this equipment.

2.

(From D-2)

Evaluate the current procedures for strainer cleaning to assure that the maximum benefit from the cleaning is obtained.

MOB DAILY,REPORT Puge E.

Professionalism, Summary of Shift, Comments The handling of repair attempt on the leaky nitrogen backup supply for the 3B Main Steam Line Isolation Valve had its good and bad points.

It was improperly scheduled for peak shift on Good Friday evening - a better time would have been a fully augmented day shift for work on a system as sensitive as this.

The PSN conducted a prudent, conservative and thorough evaluation of the problem.

Prior to authorizing the work, it was assured that all required tools and materials were available to complete the job.

The decision was made to wait.

Unfortunately, the leak appeared to be increasing, and the decision was reversed.

EUhile the work was underway, more problems than had been anticipated arose, almost requiring unit shutdown as the four hour grace period was elapsing.

A refurbished valve had to be used because spares listed on the computer were unavailable.

Fortunately, Maintenance was able to reassemble the nitrogen supply

lines, but they still leak.

Several hours of discussion with many people occurred.

Four hours of maintenance time elapsed and the problem is still unresolved.

F.

Recommendations I.

Schedule sensitive maintenance on fully augmented dayshifts..

2.

Ensure that all tools, parts and material to accomplish the repair are in hand prior to starting the work.

Area(s) for improvement Valve 3-5243 was replaced due to nitrogen leakage at the Swaglock fitting.

The store's computer inventory system showed one 3/8" Whitey valve (MGS

¹570-39779-2) in-stock and a minimum/maximum inventory criteria of 15/20.

When. I/C went to obtain a 3/8" Whitey valve, none were in-stock.

This occurrence identifies two areas for further investigation:

1.

Computer inventory showed one and none were in stock.

2.

The minimum quantity

~ is 15 and the actual inventory was down to l.

In researching the above item ¹I; a requisition-on-stores (ROS) withdrew the last 3/8" Whitey valve on peak shift, 3/31/88.

In discussions with stores personnel, the earliest a revised status would show up on the computer would be 4/2/88, With verification that the ROS information was imputted into the computer, this concern is resolved.

No research concerning the above item ¹2 was performed to determine the root cause of the anomaly between a MGS minimum of 15 and only one 3/8" Whitey valve being in stock, Further action is required to (I) expedite the purchase of 3/8" Whitey valves "and (2) determine how the inventory got to zero without the reordered shipment arriving on site.
