Earl, Turkey Point, Nuclear Plant Quality Control Department Supervisor assumed the MOS observer duties for four hours on February 12, 1988 when Mr. Dawson became ilia During this reporting 'period, Unit 3 continued in the startup process reaching Mode 3.
Unit 4 remained shutdown in Mode 5 for maintenance.
One MOS observer identified one issue as an Immediate Safety Problem.
The issue concerned a postulated failure of a Volume Control Tank level transmitter which could result in the loss of suction to the charging pumps.
Because of this concern Plant Management took, prudent actions (i.e.
operator information tags were placed in control
- room, a training brief was
- issued, and procedure changes were approved) to provide the operators with information on how to respond to this concern while it is being evaluated by our Engineering Department for applicability.
Upon completion of this evaluation, appropriate actions will be taken.
The following questionable work practices were observed:
1.
The backup nitrogen bottles for the Main Steam Isolation Valve closure system were observed to be required at 2300 psig while the safety valves on this system are set at 2250 pslgo 2 ~
File cabinets located behind the control/protection instrument racks were observed to restrict access to the area for maintenance, surveillance and/or off normal activities.
A concern was raised about the method by which outage related Plant Work Orders (two) are identified and worked during unscheduled plant outages.
In addition, if conditions do not permit working on an outage related
- PWO, some method of identificaticn of thie fact or the PWO tag in the field should be explored.

"4B" CCW heat exchanger cleaning and Gas Decay Tank release GDT088-009 were uneventful.
During the trouble shooting of control bank indication, a question was raised about the validity of using OP-1604.9 "Reactor Pull Length Control Rod System (CRDM) Test" procedure (See D.l). This procedure is generally used to move individual rods, after refueling, to check Rod Position Indications (RFI).
However, during this test the whole control bank was being manipulated.
The validity of the operator sign offs in this procedure
'was questioned as well as the appropriateness of using this procedure at all.
This question was unanswered, with much discussion, by the IGC supervision on shift.

Observed mechanical maintenance in performing PMM 022.1 6 Z on the B Diesel Generator.
The PWO package contained a good set of instructions including retest requirements.
The instructions/procedures were used efficiently by the mechanical maintenance personnel.
The journeymen were actually performing both procedures at the same time-both evolutions were controlled; journeymen were not bothered by performing Z at the same time.
The foreman was present at the jobsite.
Good use of supervision in the field.
Observed construction working on the 4B2 Circ water motor space heater.
Journeymen had instructions with them and they were using the instructions to govern their work. I later verified that they were working under an existing, proper clearance.
Observed OP 41.1-RCP starts.
All RCQ's involved utilLed the procedure to start/stop RCPs.
Observed the start of purging hydrogen from the RCS on Unit'4.
This evolution didn't get very far due to full Gas Decay Tanks.
Operations did proceed with removing hydrogen from the VCT cover gas.
Chemistry personnel informed the control room of "high" oxygen concentratiorr tn a Gas Decay Tank.
Discussed Intake Cooling Water Pump Lube water flowraters with non-licensed operator training personnel.
Opinions varied as to where (on the float) the flow fs to be read.
Training material did not specify how to read flowraters.
Walk thrus have been conducted giving out conflicting information.
Ametek technical manual gives the proper instruction.
Recommendations 1.
Reduce oxygen to the Gas Decay tanks.
Operations and chemistry'ersonn'el gave reasonable answer's as to the most probable souices-'th'ese souices should be verified and reduced.
2.
Incorporate instructions on taking readings from flowraters in the NLO training material.
(use the Ametek technical manual as a reference)
Provide this material to NLO training instructors to ensure consistent walk thrus.

Shift meetings were informative and productive; all observed shift communications were performed in a professional manner.
Preparations for nB" Emergency Diesel Generator Operability Test revealed several problems:
a)
While performing 0-OP-023 section 5.2.2.3.C lube oil cooler outlet oil temperature (TI442B) was found to be less than the 115'F required.
However, the "ready for service" light was lit; considerable discussion followed and the system engineer was consulted.
An OTSC
(¹5722) was made to 0-OP-023 and the Operability Test was satisfactorily performed.
b)
Since the nBn EDG Operability Test was delayed several hou'rs, the question came up as to whether or not an operability test of the in-service "A" EDG was required.
Technical Specif ications and Interim Technical Specifications were consulted.
Interpretations based on having both units in Mode 5 resulted in some confusion.
Operators expressed frustration that this same problem has arisen previously and interpretations were not available for them to review.
"An EDG Operability Test was not performed.
Review of PWO 6206/63 on Unit 3 Control Rod drive system step counters revealed no deficiencies; this PWO is still open.
The 3 subject step counters willbe replaced when parts are available.
Reactor Full Length Control Rod System Test OP-1604.9 was performed on Unit 4 rod J-11 under the control of "One time only" OTSC ¹5720.
Rod control performed normally and the test was completed.
A plant tour including accessible areas of Unit 3 containment was conducted.

During the observation of the nB" Diesel test run preparations, a
discrepancey was noted between the required Lube Oil Cooler outlet temperature and the observed Lube Oil Cooler outlet temperature.
Upon'urther investigation, it was discovered that the r'equired Lube Oil Cooler outlet temperature had been changed to a lower value several years ago.
- However, this change had not been reflected in the Operating Procedures or the Piping and Instrument Diagram.
Subsequently the low value was verified as correct and an OTSC was submitted to change the temperature required of the Lube Oil cooler outlet temperature in the operating procedure.
Review of the Operator Aid and Temporary Information Tag Procedure revealed several Temporary Information Tags that had not been removed from the index even though they were not visible in the field.
A tour of Unit 3 containment was conducted uneventfully.

Backup nitrogen bottles for the Main Steam Isolation Valve closure system are required to be 2300 psig which is greater than the safety setting of 2250 psig.
The number of cabinets currently located behind the control boards are restricting access to the instrument racks to perform routine maintenance, surveillances and could limitemergency access.
Several PWO's observed-have the potential to cause equipment damage (i.e..turbine trip levers rubbing against housing may preclude a trip, "3C" Moisture Seperator Reheater purge valve is not connected'electrically and water box'prfmfng'jets are n'ot fu'nctfonfng).

Westinghouse may have recommended a one out of two logic to preclude the event mentioned, however if PTN made change 'it is'not shown in 'diawings need to correct situation or drawing.
(See C.l) Correct bottle pressure or safety valve setting to: preclude the liftingof this safety when the spare bottle is valved in.
(See C.Z)
Removal of cabinets should be expedited or the areas re-organized to allow better access to the control/protection racks.
(See C.3, D.l, D.2) Work in organizing work activities has been conducted,
- however, methods for improved output, parallel tasking and expediting work need to be investigated and where appropriate adopted.
Many PWO's were inplace on system/components which were overhauled during the last outage, but the items on these PWO's were not worked.
(See D.3) The method of tracking, testing identification and completion needs to be given to the PSN's.
The concern is over delayed testing of equipment not carried in the Equipment Out of Service (BOOS) log, yet which requires post maintenance testing prior to being operable.

As a minimum, the Assistant Plant Supervisor Nuclear should approve all activities in the switchyard.
Uerify status of other feeds if manipulation of more sensitive breakers are necessary.
Conduct training on less sensitive breakers (Ie, if the plant is shutdown, use the main transformer breakers)
Plant requested switching orders should be obtained via the control room 2.
Remind personnel that the ear protection signs are still in effect and must be followed.

Beginning of shift meeting (midnight shift) provided examples of continuing efforts toward good communication.
a)
PSN described events on day shift which led to lube oil spill, using this example he then encouraged all personnel on shift to be attentive to detail when performing individual jobs.'lso he challenged everyone on shift to be active participants.
by.questioning any activities which did not appear to be consistent with plant conditions.
- b)
Examples of miscommunication which led to the earlier oil spill were reviewed with suggestions for better performance.
PSN provided an overview of the process involved in the upcoming, Unit 4 safeguards test.
Maintenance discipline supervisors described the roll their people would play in the test. Last minute instructions were transmitted to ensure all data taken would be ready at the beginning of the test.
- However, outside operators (NLO's) were not designated for specific functions with Unit 4.
This resulted in some operators performing functions on both Unit 3 which was preparing for mode change and on Unit 4 during safeguards test.

Communications and coordination were very good.
Due to the safeguards test, a large number of people were in the Control Room.
Noise level were adequately maintained and when too many people were collecting, people were asked to leave.
Problems were,researched and corrective actions taken as appropriate.
Very good discussion during shift turnover that covered the oil spill, what contributed to it, and also what actions may have helped prevent it. Personnel were also briefed on the safeguards test.

MOS DAILYREPORT'age Professionalism, Summary of Shift, Comments 2.
Team effort and professionalism were evident throughout the night with operators assisting each other in identifying a potential to activate the trip relays prior to the event (work was stopped),
timely performance of schedule and startup-related testing and working with IGC to help get the Generator Gas Liquid Monitors back'n service (System repairs still working).
Some minor potential problems were identified, discussed, and immediate corrective actions were taken to prevent an actual problem from occurring which could have had a safety impact (i.e. some gas bottles were not tied down. very well but the action corrected the situation and placed them in procedural and safety compliance).

(See D.l) A more appropriate location for storing the "C" bus grounding devices should be identified other than the switchgear room.
This is a small area being even more restricted by the grounding devices (one of which is on a pallet and cannot be moved).
(See D.2) Replace handrails and identify reason rails were left down rather than put back when work requiring their removal was complete.
Personnel accountable should be counseled on the importance of properly maintaining this type equipment.
(See D.3) Lockers should be moved to a more appropriate location or appropriate fire equipment provided to protect the major cable run.
(See D.4) Breakers should be properly stored in their cubicles whenever they can.
The event of work being done and a grounding device in use should be the only reason breakers are stored outside of the cubicle.
(See D.5) Supervisors need to review the Administrative Procedure dealing with plant information and labeling so that they are made aware of the plant policy and expectations in this area.
(See D.6)
Valve should be connected to prevent damage to the Moisture Seperator Reheater tube bundle.
(See D.7) Fix levers so that the testing can be performed with minimum risk and a turbine trip willoccur ifcalled upon.
(See D.8) Clear up the inside of the "3F" and "3G" load centers.
