D.B.'I&C LAB 6-10-85 h
p On the morning of 9 June, as85, I was called in to work by K. Brubaker at approximately.0300. Upon arriving I was informed that the plant was in an emergency situation and there was a great need to get some essential instrumentation repaired.
After some discussion on general plant conditions, M. Dutkiewicz and I went to the Control Room to perform the Source Range Functional Test on NI-2.
We obtained permission from the Shif t Supervisor, Mr.
T.. Lehman, in the Control Room. After obtaining the keys for RPS Channel #1, we proceeded to open the cabinet doors. At this time, we were surprised to see that NI-2 was working and giving an indication on the Log Amp Mete.
We proceeded to run the Source Range Functional Test on NI-2 with all parameters reading within the allowed tolerances. After completing this test on NI-2, NI-1 (Channel 2 RPS) was tested in the same manner and was also found to be in tolerance. We turned the completed tests over to the Shift Supervisor after signing off the acceptance criteria and returned to the I&C Shop.
It was my understanding that prior to running the Source Range Functional
. Test on NI-2, this particular NI was not functioning at all.
M. Dutkiewicz stated that before my arrival for work, he had checked NI-2 visually in the RPS cabinet and it was not indicating at all on the Log Amp Meter. The power supply was indicating proper supply voltage (approx. 2050 VDC), but the
(
detector circuits themselves were not working.
I cannot say exactly when NI-2 began to function properly, but it was working and giving proper indication when we opened the RPS Channel #1 doors to test it.

PRECAUTIONS AND TTMTTATIONS
.)
4.1 No core alterations will be made during conduct of this test.
4.2 When the NI/RPS Cabinet doors are opened, an alarm to this effect will be annunciated in the Control Room.
4.3 If any readings are out-of-tolerance, re-align equipment per the applicable Maintenance Instruction and annotate in the equipment files. If re-alignment is unsatisfactory, contact the I&C Engineer or Designated Reviewer for corrective action. Computer pointe R796 and RgG5, and the recorder indications are for information only and do not affect ehmanal operability.
4.4 NI/RPS module locations given throughout this procedure are interprete1 as follows: Al-03-04 is subassembly A, Cabinet 1, Row 2, Position 4.
NI-1 is associated with Subassembly B and NI-2 is associated with Subassembly A.
4.5 Before testing any module in the NI/RPS, it should be energized for at least 30 minutes.
4.6 The rotary test selector switch on the Source Range has a machemical stop between.the TEST /0PERATE and OPERATE positions.
To move the switch from TEST /0PERATE to OPERATE, it is necessary to push the switch knob in and hold while turning the switch.
It is not necessary to push the knob when switching between any c.i other positions. The switch should be'left in the TEST /0PERATE position for at least five seconds before going to the OPERATE position to allow transients to die out.
4.7 For purposes of checking the Rod Control Panel OUT INEBIT indication the CRD Control System should be energized. The computer and annunciator panel are assumed energized for verifica-tion of E GE SUR alarms.
6 4.8 When performing this surveillance test while in Mode 6, insure source range audible indication is connected to either NI-1 or NI-2 upon completion of testing.
l i
i 9
4.9 The SUR ROD WITEDRAWAI INRIBIT isn't required during mode (1) one operation. Even though it is an integral.part of the instrument string, it isn't required to be tested.
Certain l
aceps in this procedure will therefore be marked N/A as indicated t
in that step.

Verified t# Date [ 'h (( 91 V 7.2 The Source Range channel functional check has been performed and setpoints are within specifications., 9 Date /r -9 b Verified "~ r NOTE: Section 7.2 shall be N/A during Mode (1) operation. l I E l l. i l' t WORK PERFORMED ON #1 MFP p i A review of the chart recorders connected to the MFPT controls l showed the LS-16 Limit Switch was the first indication of the trip. [ Because SV 12 was not energized, we eliminated all the protective trips except overspeed. I i The information from the Technical Section review of the post trip data showed the pump increasing in speed just before the trip, i Because the chart recorder connected to TP 111 didn't show any change in speed reference signal, we determined the cause of the over-speed was probably in the speed feed *'tek or valve position feedback circuits. We then took a set of readings on Number 1 Pump and compared them to Number 2 Pump. We could find no significant difference between the two control circuits. The I&C mechanic suggested the problem could be a loose connection. I made the decision to wait for a GE field rep before going any further with troubleshooting. When I talked to GE, they agreed that it appeared the pump tripped on overspeed. They had no one available to come to the site immediately. to-li tr (,s Date T.R. Isiff TRI/er i f', b .L WORK DONE ON #1 MFP 6-9-85 _D On June 9, 1985, Ken Brubaker called me at approximately 0305 and told l me to go to the plant as it had tripped and there were several problems. j. Upon arrival, Ken Brubaker told me #1 MFPT had tripped and to look for what j may have caused the problem. Mike Dutkiewicz was on 3rd Shift and had j removed the charts from the Gould Brush Recorders we had connected to different points on #1 MFP and in the MDT-20 cabinet. These recorders were connected to monitor a previous problem with #1 MFP and by studying the charts I determined the pump tripped from a different problem this time. Although the charts told us what the problem wasn't, it did not tell us what i the problem was. l Later Tom Isley told me the Tech Section had determined the pump tripped on over speed. One of the Gould Recorders was connected to Board Position 2 between TP 110 (Gnd) and TP 111 to monitor.the pump speed reference signal. At the time of the pump trip the chart did not show any change in the speed j setpoint signal from ICS. In turn this eliminated the ICS System as the l source of the problem. I proceeded to check the voltages in the MDT-20 cabinet which accepted the turbine speed feedback level signal from the feed pump. I checked the waveform from the shaft speed pick up probes (SSPU-1 and SSPU-2) to the MPT-20 cabinet, and also the voltages at 18 different test points on Board Positions 4, 5, and 6 in the MDT-20 cabinet. I compared these voltages and waveforms to those of #2 MFPT and could find no hard failure or anything conclusive as to why the pump tripped. I thought the problem could have possibly been a loose connection on either of the SSPU probes or on the ,() LVDT located at the pump. It was decided not to probe around at the pump at this time as it was not known whether GE would come in to look at the problem. I did not pursue the problem any further. All work was done per MWO 1 ' 1935-00. f-//-ff h. Date Edward W. Gensler i [ EWG/er r I i l

OBJECTIVE This test is to verify that two independent steam generator auxilia-ry feedwater pumps and associated flow paths are operable at least once per 18 months. This test is performed in five phases. Phase 10l I is done during Modes 1, 2, or 3, Phase II, V and VI are done during Modes 5 or 6.
(TS 4.7.
Phase I - Verifies that each pump starts automatically upon 1.2.B.1) receipt of an auxiliary feedwater actuation test signal.
Phase II - Verifies that each automatic valve in the flow path (TS 4.7.
actuates to its correct position on an auxiliary feedwater 1.2.B.2 actuation test signal. Completes any valve testing required by to 4.0.5) Technical Specification 4.0.5 which has not been completed by ST 5071.01.
Phase III - Measures the minimum recire flow at 3600 RPM in Modes 1, 2, or 3.
Phase IV - Verifies the AFPT speed changer motor and service water suction valves respond to signals from the Auxiliary Shutdown Panel 02 any mode.
10l Phase V and VI - Verifies that the check valves ' required to be tested C,?
by ASME code meet forward and reverse flow acceptance criteria.

i (TS) 4.3 PHASE I ONLY: Steam Generator pressure is > 800 psia, such that testing will be done at the conditions specified by Technical Specification 3.7.1.2.
4.4 DURING THE PERFORMANCE OF THIS ST, THE TRAIN FOR WHICK THE ST IS BEING PERFORMED WILL NOT PERFORM ITS SAIITY FUNCTION. IF THE SYSTEM IS NEEDED FOR SAFETY FUNCTIONS, IT IS THE RESPONSI-BILITY OF THE OPERATOR PERFORMING THE ST TO RESTORE THE SYSTEM i
TO NORMAL.
4.5 During Phase I, an Operator by AF 3870 (AF 3872) or by D 107 l
(BF 1262) must be in direct comunuaication with the Control Room
(
when the breaker is open. This allows the Control Room to immediately direct the Operator to open the valve or close the breaker upon an STRCS actuation.
If the Operator is by the valve, he must have a headset or similar device with him at all times. The Gai-tronics loudspeaker is only acceptable if the Operator is at the breaker.

4.6 PHASE III ONLY: When AF 23 is open, an Operator by the AFP being tested must be in direction communication with the Control Room. This operator will close AF 21 (AF 22) when the Control Room notifies the operator of an SFRCS actuation or any other unusual event. The operator must have a headset or similar device with him at all times. The Gai-tronics loud-speaker is NOT acceptable. This applies only when AF 23 is open.
NOTE:
It has been found that AF 21 (AF 22) is easier and faster to close than AF 23.

On the morning of 9 June, 1985, I was called in to work by K. Brubaker at approximately 0300. Upon arriving, I was informed that the plant was in an emergency situation and there was a great need to get some essential instrumentation repaired.
After some discussion on general plant conditions, M. Dutkiewicz and I went to the Control Room to perform the Source Range Functional Test on NI-2.
We obtained permission from the Shif t Supervisor, Mr.
T,.
Lehman, in the Control Room. After obtaining the, keys for RPS Channel #1, we proceeded to open the cabinet doors. At this time, we were surprised to see that NI-2 was working and giving an indication on the Log Amp Meter.
We proceeded to run the Source Range Functional Test on NI-2 with all parameters reading within the allowed tolerances. After completing this test on NI-2, NI-1 (Channel 2 RPS) was tested in the same manner and was also found to be in tolerance. We turned the completed tests over to the Shift Supervisor after signing off the acceptance criteria and returned to the 16C Shop.
It was my understanding that prior to running the Source Range Functional Test on NI-2, this particular NI was not functioning at all.
M. Dutkiewicz stated that before my arrival for work, he had checked NI-2 visually in the RPS cabinet and it was not indicating at all on the Log Amp Meter. The power supply was indicating proper supply voltage (approx. 2050 VDC), but the
(
detector circuits themselves were not working.
I cannot say exactly when NI-2 began to function properly, but it was working and giving proper indication when we opened the RPS Channel #1 doors to test it.

functional check of the Nimbin Assembly. Mode 6 T.S. 4.9.2 requirements (Core Alterations).
NOTE:
The trigger point shall be set at approx-instely 5-10 CPS above che,present indication (background CPS) in the RPS Channel which is being used for the audible indication.
CPS Record Desired Trigger Point.
j 6.2.1 Turn OFF Realistic Amplifier (Spkr to CTXI).
6.2.2 Make sure voluma on Nim Bin is at audible level.
6.2.3 Obtain RPS chi}& door key and place SRTM Test Selector switch in 1 Ez position.
6.2.4 Nim Bin Meter should be at full scale (pegged) due to switching thru 100K Es and 4K Ez switch positions on SRIM.
Turn thg CPS full scale switch on Rate Meter Module from 10 to 105 position in order to speed up the decay of the Rate Meter to 1 Ez as read on the Nim Bin.
6.2.5 When meter has fully decayed, turn CPS full scale switch back to the 102 position.
NOTE: Prior to switching the SRTM Test Selector switch to the 4K Es position, observe mater in the Nim Bin to see that triggering of audible howler occurs at
- Desired Trigger Increasing, as the test operate switch is placed in the 4K Ez position.
(Meter will increase rapidly to full scale when test OP Switch is placed in 4K Hz position.
6.2.6 Place the SRIM Test Operate switch in the 4K Ez position (while observing Ntra Bin Meter for howler to trigger at
- Desired Trigger Increasing).
If trigger set point is set properly, audible indication should be heard.
If not, adjust trigger set point pot for audible howl at desired trigger.
6.2.7 After a few seconds. place the SRIM Test Selector switch
![
in the 1 Ez position.
~Q.
pr(73 ST 5091.01
- j 6.2.8 With the audible howl coming from the Nim Bin, allow the meter to decay on its own down to 1 H:.
This should take approximately 4-6 minutes. At the point the meter decays to = 15 to 20 CPS on the Nim Bin, turn ON amplifier and speaker to Containment and check for audible noise in CDir. Adjust master volume on -
"'c either up or down as needed. When 0% TURN OFF amp to CDC.
6.2.9 Continue to watch meter decay down. At the desired trigger the audible howl should stop.
6.2.10 Place SRTM Test Selector switch in OPERATE position.
Reset Memory Lamp. Lock cabinet.
6.2.11 Nim Bin Meter will again be pegged hig1 due to switching from 1 Hz position to OPERATE on SRIM.
6.2.12 Turn the CPS full scale switch from 102 to 105 position to speed up the decay of the Nim Bin meter.
6.2.13 When meter has fully decayed, place CPS full scale switch in 102 position.

PRECAUTIONS AND I. IMITATIONS
.u) 4.1 No core alterations will be made during conduct of this test.
4.2 When the NI/RPS Cabinet doors are opened, an alarm to this effect will be annunciated in the Control Room.
4.3 If any readings are out-of-tolerance, re-align equipment per the applicable Maintenance Instruction and annotate in the equipment files. If re-alignment is unsatisfactory, contact the I&C Engineer or Designated Reviewer for corrective action. Computer points R796 and R805, and the recorder indications are for information only and do not affect channel operability.
4.4 NI/RPS module locations given throughout this procedure are interpreted as follows: Al-02-04 is subassembly A, Cabinet 1, Row 2, Position 4.
NI-1 is associated with Subassembly B and NI-2 is associated with Subassembly A.
I 4.5 Before testing any module in the NI/RPS, it. should be energized for at least 30 minutes.
4.6 The rotary test selector switch on the Source Range has a mechanical st op between,the TEST /0PERATE and OPERATE positions.
To move the switch from TEST /0PERATE to OPERATE, it is necessary j
to push the M tch knob in and hold while turning the switch.
j It is not me.:essary to push the knob when switching between any c,;)
4 other positions. The switch should be left in the TEST /0PERATE position for at least five seconds before going to the OPERATE j
position to allow transients to die out, i

indication the CRD Control System should be energized. The computer and annunciator panel are assumed energized for verifica-tion of HIGH SUR alarms.
4.8 When performing this surveillance test while in Mode 6, insure source range audible indication is connected to either NI-1 or NI-2 upon completion of testing.
9 4.9 The SUR ROD WITHDRAWAI. INRIBIT isn't required during mode (1) one operation. Even though it is an integral part of the instrument string, it isn't required to be tested.
Certain steps in this procedure will therefore be marked N/A as indicated in that step.

I WORK PERFORMED ON #1 MFP O'
1A' A review of the chart recorders connected to the MFPT controls showed the LS-16 Limit Switch was the first indication of the trip.
i Because SV 12 was not energized, we eliminated all the protective trips i
except overspeed.
l The information from the Technical Section review of the post trip j
data showed the pump increasing in speed just before the trip..
Because the chart recorder connected to TP 111 didn't show any change in speed reference signal, we determined the cause of the over-speed was probably in the speed feedback or valve position feedback 4.
circuits.. We then took a set of readings on Number 1 Pump and compared i
them to Number 2 Pump. We could find no significant difference between the two control circuits.
l The I&C mechanic suggested the problem could be a loose connection.
i I made the decision to wait for a CE field rep before going any further with troubleshooting..
1 When Italked to GE, they agreed that it appeared the pump tripped t
on overspeed. They had no one available to come to the site inumediately.

WORK DONE ON #1 MFP 6-9-85 On June 9, 1985, Ken Brubaker called me at approximately 0305 and told me to go to the plant as it had tripped and there were several problems.
Upon arrival, Ken Brubaker told me #1 MFPT had tripped and to look for what may have caused the problem. Mike Dutkiewicz was on 3rd Shift and had removed the charts from the Gould Brush Recorders we had connected to different points on #1 MFP and in the MDT-20 cabinet. These recorders were connected to monitor a previous problem with #1 MFP and by studying the charts I determined the pump tripped from a different problem this time.
Although the charts told us what the problem wazn't, it did not tell us what the problem was.
Later Tom Isley told me the Tech Section had determined the pump tripped on over speed. One of the Gould Recorders was connected to Board Position 2 between TP 110 (Gad) and TP 111 to monitor the pump speed reference signal.
At the time of the pump trip the chart did not show any change in the speed setpoint signal from ICS.
In turn this eliminated the ICS System as the source of the problem.
I proceeded to check the voltages in the MDT-20 cabinet which accepted the turbine speed feedback level signal from the feed pump. I checked the waveform from the shaf t speed pick up probes (SSPU-l and SSPU-2) to the MPT-20 cabinet, and also the voltages at 18 different test points on Board Positions 4, 5, and 6 in the MDT-20 cabinet.
I compared these voltages and waveforms to those of #2 MFPT and could find no hard failure or anything conclusive as to why the pump tripped.
I thought the problem could have possibly been a loose connection on either of the SSPU probes or on the
(;
LVDT located at the pump.
It was decided not to probe around at the pump at this time as it was not known whether GE would come in to look at the problem.
I did not pursue the problem any further. All work was done per MWO l 1935-00.

OBJECTIVE This test is to verify that two independent steam generator auxilia-ry feedwater pumps and associated flow paths are operable at least once per 18 months. This test is performed in five phases. Phase 10l I is done during Modes 1, 2, or 3, Phase II, V and VI are done during Modes 5 or 6.
(TS 4.7.
Phase I - Verifies that each pump starts automatically upon 1.2.3.1) receipt of an auxiliary feedwater actuation test signal.
Phase II - Verifies that each automatic valve in the flow path (TS 4.7.
actuates to its correct position on an auxiliary feedwater 1.2.B.2 actuation test signal. Completes any valve testing required by to 4.0.5) Technical Specification 4.0.5 which has not been completed by ST 5071.01.
Phase III - Measures the mini-se recire flow at 3600 RPM in Modes 1, 2, or 3.
Phase IV - Verifies the AFPT speed changer motor and service water suction valves respond to signals from the Auxiliary Shutdown Panel in any mode.
10l Phase V and VI - Verifies that the check valves ' required to be tested by ASME code meet forward and reverse flow acceptance criteria.

ST 5071.02.11 r
4.6 PHASE III ONLY: When AF 23 is open, an Operator by the AFP being tested must be in direction communication with the Control Room. This operator will close AF 21 (AF 22) when the Control Room notifies the operator of an STRCS actuation or any other unusual event. The operator must have a headset or similar device with him at all times. The Gai-tronics loud-speaker is NOT acceptable. This applies only when AF 23 is open.
NOTE:
It has been found that AF 21 (AF 22) is easier and faster to close than AF 23.
12 4.7 The pushbutton to light method for valve stroke timing will be used throughout this procedure. This means START the stop watch simultaneously when the pushbutton is depressed, STOP the stop watch when the valve indicator light illuminates.
