7 On 11/12/86, it was discovered, during a review of environmental qualifications, that, the North Safety Injection Pump rrator had been serviced by a non QA-qualified vendor in May of 1981.

The pump was rerraved fran

service, due to our inability to conclusively prove the impact of the servicing on the motors envirozxrental qualifications.

The cause of the event has been determined to be due to personnel error in that the vendor was not QA qualified.

We believe that the servicing performed on this motor did not degrade it's ability to function during an

accident, had one occurred.

To verify our belief the rrator willundergo envirormental qualification tests.

A supplemental report contahrring the test program willbe suhnitted by 2/27/87.

On'l/13/86 the rrator in question was rerraved and replaced with a certified motor.

Since the occurence of the subject event (1981) adminstrative controls have been strengthened, which ensures the use of qualified vendors when necessary.

Based on the effectiveness of these controlsP no additional preventive action is currently planned.

3 Ccnditians Prior to Occurence Unit Two - 90 percent reactor thermal power.

Descri tion of Event On Nova>her 12, 1986, it was discovered, during a review of envirormental qualifications, that the Unit Two North Safety Injection (EIIS/BQ) Puap motor (EIIS/M)) had been serviced by a non QK-qualified vendor in May of 1981.

Subsequently the pump was ramved fran service, (declared inoperable at, 1500 an 11/12/86) due to aur inability to conclusively prave the unpact of the servicing on the motors envirorxnental qualifications.

The Unit Two North Safety Injection Pm@ mcrtmr had been sent to the vendor in May of 1981 to have the motor dynand.cally balanced.

However, the vendor also performed stean cleaning of the mtor and a varnish treatment of the stator coils.

'Ibis work was beyond the scope of the requested repairs.

The pump motor was returned to the plant and installed in May, 1981.

The perp rmtor had been in service (without problems) until November 12, 1986.

There were no other inoperable structures, canponents or systems that contributed to this event.

Cause of Event

The cause of this event has been determined to be due to personnel error in that involved Maint./Purchasing personnel did not consider the QA;qualification of the vendor.

In a non Qh-facility there is no assurance that any repairs done would be performed to original nestor requirements.

Anal sis of Event We have concluded that the use of this motor was in violation of Technical Specification 3.5.5 and consequently, is reportable per 10CFR50.73(a)

(2) (i) (B).

During the period of May, 1981 to November, 1986 the rotor was periodically run per Technical Specification Surveillance requiranents.

A supplemental report con~zinc~ the test program and its schedule will be suhnitted by February 27, 1987.

Corrective Actions

On Natter 13, 1986 the Unit Two North Safety Injection Punp mortar was rawved and replaced with a certified motor.

The motor reneved willbe subjected to the required enviromantal qualification tests to verify that the rmtor's ability to function under accident conditions was not degraded+

Since the occurence of the subject event (1981) adminstrative controls have been strengthened, which ensures the use of qualified vendors when necessaxy.

Based on the effectiveness of these controls, no additional preventive action is currently planned.
