Docket No. 50-285
Dear Mr. Clark:
NUREG-0737, Item II.K.3.17 Report on Outages of Emergency Core Cooling Systems (ECCS)
The Commission's letter to Omaha Public Power District, dated July 14, 1982, requested the District provide additional information regarding the subject TMI Action Plan item. Accordingly, the attached Tables 1, 2, and 3 provide the information requested by Item 1 of the subject letter and the attached Table 4 provides the information requested by Item 2.
Table 1 specitically identifies diesel generator outages resulting from surveillance testing activities. Tables 2 and 3 detail diesel generator outages resulting from component failures identified by planned, un-planned, or preventive maintenance. Table 2 includes all planned and preventive maintenance outages and Table 3 identifies the unplanned maintenance outages which were reportable as Licensee Event Reports.
Table 4 addresses all ECCS component outages resulting from surveillance testing.
In most cases, the exact duratir,n of a specific surveillar. e test was not available, so a best estimate, based en the average aui ation of completing the test, has been provided. It shoulo 31sc be noted that removing a component from service for surveillance testing does not necessarily render that specific ECC train or system inoperable. As an example, Surveillance Test ST-SI/CS-1 (listed in Table 4) requires the 00 8208240(7%

In addition, DG-1 would have supplied bus 1A3 (DG-2 feeds bus 1A4) had all off-site power been lost. There were no inoperable engineered safe-i guards components associated with bus lA3 while DG-2 was inoperable.

Attachment No. 2 l
Corrective Action The magnetic sensing unit for the switching tachometer (speed switch) had been removed on April 27, 1976, so that routine maintenance could be per-formed on DG-2 air start motors. This sensing unit is in close proximity to the air start motors and interferes with accessability for air start motor maintenance. After completing maintenance on the air start motors, DG-2 was started to prove operability. This start was called for by pro-cedure. After sensing 100 rpm the speed switch generates a permissive signal to disengage the air start motors. However, due to the improper air gap setting, the speed switch failed to generate this permissive and the air start motors consequently did not disengage. The air gap for the magnetic pick up unit was properly set and DG-2 successfully started with proper disengagement of the air start motors at 1710 hours0.0198 days <br />0.475 hours <br />0.00283 weeks <br />6.50655e-4 months <br /> on April 27, 1976 (see Maintenance Order No. 10918). The error was procedural in that the maintenance proccoure did not call for checking the air gap setting whenever the speed sensing unit is re-installed. Hereafter this setting vill be checked.

2 The Fort Calhoun Station electrical distribution system is so designed that no single failure can prevent the safe shutdown cf the plant if required. During the time that diesel generator number 1 was inoperable, diesel generator number 2, the 161 K7 supply, and the 345 KV supply were available.
The initial failure (generator overexcitation) occurred on July 12, 1978.
At this time an investigation was initiated in an attempt to discover the failure
=echanism. The investigation showed that the current boost which actuated on low generator tenminal voltage had drifted up. This drift upward coupled with a low grid voltage due to summer load on the 161 KV grid was felt to be the failure
~
=echanism, since the generator goes to maximum excitation on actuation of the relay. The relay was reset and the diesel was load and run for approximately 1
20 minutes on July 13,1978 (this short load time was due to an electrical storm at the station which could potentially damage the diesel while synchrcnized to the bus). The diesel was considered operable at this time.
On July 14, 1978, the monthly surveillance test was repeated on diesel generator number 1 to completely verify operability. At approximately 55
=inutes into the test the generator again went to maximum excitation and was subsequently tripped. Upon further investigation, two problem areas were identified. The generator terminal reference potential transformer plug in stabs were found to be loose, which may have caused the overexcitation, and the reference voltage sener diode in the generator voltage regulator was found to be defective, which could have caused the failure. The stabs were repaired
, and the ener was replaced with a 10W 2hV sener diode (the original equipment
] zener diode is no longer available). General Electric was consulted on the
! change to an ECG5198 diode and concurred with the replacement diode. The voltage stability of the generator was then reset and recovery time was tested snd set at less than 1 second at no load. Per telecon with General Electric l on July 1h,1978, the worst case recovery is at no load.
The diesel was then retested and found to be operable on July lh, 1978, by surveillance test ST-ESF-6. This is considered to be an isolated failure and no further action is anticipated.

j' LIR 73 s02k Cnaha Public Power District Fort Calhoun Station Unit No. 1 Docket No. 05000285 ATTACEENT NO.1 Safety Analysis The Fort Calhoun Station Unit No. 1 Engineered Safety Features Systa=
is so designed that no single failure can prevent the safe shutdown of the plant if required. During the ti=e Diesel Generator No. I was inoperable (during repair and testing), Diesel Generator No. 2 was operable and both the 161 K7 and 3k5 KV supplies were available.
During the period of trouble shooting and testing on August 9,1978, with the exciter =anufacturer and subsequent testing on' August 30,.1c78, as recc== ended by the exciter manufacturer, the following infor:stion was discovered: .
(1) During the initial one hour run which lead to the failure of Diesel Generator No.1, it was noted the _ generator cut-put current centinued to increase throughout the entire run vithout any operator action.
(2) A bench test of the reference ener diode shoved continual drift up. This was the tener which was replaced and reported in LER 78-022. The drift was within =anufacturer tolerance. The original diode was ther= ally ec=pensated and exhibited a smaller drift, hcvever, this exact replace-
=ent is no longer =anufactured.
(3) At the time the failure occurred, the generator exciter was approx *-ately at its naxi=u= long time exitation limit, which was approaching the saturation limits of the machine.
(h) The generator droXp cc=pensation is vired to boost current if generator current increases, rather than a nor=al machine set up for parallel operation on a bus, in which the droop ccmpensation tends to limit current.
Eased on the data and information collected during testing and trouble-shcoting Diesel Generator No. 1, the following hardware and procedure changes vere instituted:
(1) The :ener diode referenced earlier was changed ou: to a 5CW
- ener diode to provide greater stability. The subsequent test shoved the diode did drift but to a =uch s=a er extent than the 10W :ener.
(2) The generator exciter circuit was designed to provide maxi-
-"- -"---
- boost in starting the Ingineered Safety Features Leads. As a result of this, when paralleled to the bus , the
l

C=aha Public Power District Fort Calhoun Station Unit No. 1 Docket No. 05000285 ATTAC*
r E T NO. 1 (continued) drcop CT influence on the regulator operation may not be able to be ec=pensated for by a change in ter=inal voltage on the =achine (parallel operation vill result in small terminal voltage changes with excitation and large current changes or power facter changes). To li=it current output of the generator,ad=inistrative centrols have been placed on the machine during parallel operation to li=it the current to belov 400 a=ps at 2500 l KW (which is away frc= the saturation region of the nachine). A cc=puter alar = for the generator has also been provided to alar = at h00 a=ps.
l In discussing this proble= with the exciter =anufacturer and based on the test data.it has been deter =ined than though the generator failed when paralleled to the bus, at no ti=e was it inoperable, if required, to perfc== its design function for Engineered Safety Feature creration.
When the generater is operated carrying the ES? loads, after the initial lead starting, it vill provide only the current required to =aintain the lead. Any shift of the exciter circuit vill result in a drift of ter-
=inal voltage and a small drift (aV/Z) of ' current, negating the droop cc=pensatica effect.
l The failure during parallel operation was deter =ined to result frc=
- two areas; the drift of the ener diode and a s=all load change on the bus during the generater test. The ener diode drift and bus condition resulted in the generator being at approximately the =axi=un long time excitation li=its. Any s=all voltage decrease or lead increase On-the l bus at this time vould have required more current out of the generator, l
resulting in the drcop circuit positive feedback, increasing excitation with little er no negative feedback frc= the exciter's voltage input.
At this time the machine vent to maxi =u= excitation and blev the field protection fuses.
The generator was subsequently retested and the current was 1L=ited belev h00 a=ps. No proble=s were encountered and no further action is anticipated.

P LER 80-014 Omaha Public Power District Fort Calhoun Station Unit No.1 Docket No. 05000285 ATTACHMENT N0. 1 Safety Analysis The Fort Calhoun Station Unit No.1 Engineered Safety Features System is so designed that no single failure can prevent the safe shut-down of the plant if necessary. During the time diesel generator DG-1 was inoperable, diesel generator DG-2 was operable as were the 161 KV and 345 KV supplies thus providing more than adequate capability for safe shutdown of the plant should the unlikely event of an accident occur.
It should be pointed out that DG-1 was considered inoperable only during the time that the transformer was being changed out since this transformer only feeds the oil immersion heater for DG-1 and associated annunciation. Should the need have arisen, DG-1 would still have automatically started per engineered safeguards and performed its -
design function as described in the Final Safety Analysis Report.

. . a LER No.80-014 Omaha Public Power District Fort Calhoun Station Unit No.1 Docket No. 05000285 ATTACHMENT NO. 2 Corrective Action M.0. #6421 was written to replace the failed Westinghouse 480/120, 100 Va, Model 2-F-47-1 transformer. Since Westinghouse no longer manu-factures this transformer, (it was superseded by their model 1F0892) and no exact duplicate / spare was available, it was replaced using an equivalent GE 100 Va, 480/120 volt transformer. Upon replacement, the diesel was tested satisfactorily for operation as was all transformer related circuitry and the diesel DG-1 was returned to service.
As a further note, the Westinghouse model 1F0892 transformer which has superseded the failed model 2-F-47-1, and is electrically equivalent or superior to the model 2-F-47-1 has been ordered and will be installed in DG-1 circuitry as soon as procurement allows. -
