10CFR21 REPORT OF ALLIS CHALMERS SWITCHGEAR BREAKERS REFURBISHED BY SITEK OF MILWAUKEE The following information is provided with respect to a 10CFR21 reportable occurrence. at Palisades. A thirty day written follow up report will be submitted.
On April 15,1992, the evaluation of improperly terminated wires on the closing relay for the 2400V switchgear breaker to P-66A, High Pressure Safety Injection Pump was determined to be 10CFR21 reportable.
On April 15,1992, the evaluation of improperly terminated wires on the closing relay for the 2400V switchgear breaker to P-66A, High Pressure Safety Injection Pump was determined to be 10CFR21 reportable. These improper wire terminations were completed during a solenoid operated breaker refurbishment by Sitek of Milwaukee. Seven 2400V solenoid operated breakers from the Palisades Plant were sent to Sitek of Milwaukee for refurbishment. We believe that all seven solenoid operated breakers have the improper wire terminations.

One of the breakers supplies power to the safety related HPSI pump, while the other six breakers supply non-safety grade equipment. To date four breakers (including the safety related one) have been inspected and fixed and all exhibited the same problem. The remaining three breakers will be inspected at a later date.

10CFR21 REPORT OF ALLIS CHALMERS SWITCHGEAR BREAKERS REFURBISHED BY SITEK OF MILWAUKEE The following information is provided with respect to a 10CFR21 reportable occurrence. at Palisades. A thirty day written follow up report will be submitted.

On April 15,1992, the evaluation of improperly terminated wires on the closing relay for the 2400V switchgear breaker to P-66A, High Pressure Safety Injection Pump was determined to be 10CFR21 reportable. These improper wire terminations were completed during a solenoid operated breaker refurbishment by Sitek of Milwaukee. Seven 2400V solenoid operated breakers from the Palisades Plant were sent to Sitek of Milwaukee for refurbishment. We believe that all seven solenoid operated breakers have the improper wire terminations.

One of the breakers supplies power to the safety related HPSI pump, while the other six breakers supply non-safety grade equipment. To date four breakers (including the safety related one) have been inspected and fixed and all exhibited the same problem. The remaining three breakers will be inspected at a later date.

  • No operational problems due to the improper terminations have been noted on any of the affected breakers. Problems expected if the terminations came loose would be a failure of the breaker to close. At the present time all the uninspected breakers are closed.

The original procurement of these breakers was before the IEEE standards were developed. These breakers were bought as commercial items and grandfathered to class lE. These breakers were refurbished by Sitek of Milwaukee, who did not have a quality program, and Consumers Power Co. applied our QA program and 10CFR21 reportability.

2. The basic component which contains defects.

Allis Chalmers 2400/4160 V switchgear

3. The firm supplying the basic component which contained a defect.

Allis Chalmers 2400/4160 V switchgear refurbished by Sitek of Milwaukee formerly Seimens Energy and Automation P.O.Box 2387 5700 W. Hemlock Milwaukee, Wi 53223 4a. Nature of the defect.

The wires on the closing circuit relay {52X) were improperly landed.

See attached sketch.

4b. The safety hazard which could be created by such a defect.

The breaker may fail to close when required if the wires come detached from the terminals.

5. The date when information of the defect was obtained.

The improper terminatio~ was first noted on 3/20/92 and corrected on the initial breaker on 3/24/92. It was subsequently evaluated and linked to the refurbishment _of the breakers on 4/15/92.

6. The number and location of all such components subject to this Part 21 Sitek of Milwaukee has stated that the only nuclear facility to whom they have supplied refurbished breakers is Palisades. Palisades has identified seven (7) solenoid operated breakers which are affected.

Stored energy breakers also refurbished by Sitek do not contain the affected closing relay and therefore are not affected by this Part 21.

All seven breakers are.installed in the Palisades Plant. Four of the seven have been inspected and found to contain the improper terminations.

These terminations were corrected on those four breakers. The remaining three are installed on a non-safety related bus and are presently closed.

Palisades will inspect those breakers at a future date.
