DEFECTS AND NONCOMPLIANCE PART 21 -THOMAS AND BETTS PRINTED CIRCUIT BOARDSThe following was received via fax:"This report documents the supply of faulty Logic Power supply assembly printed circuit boards for a Cyberex20KVA Model AC Power Supply. These power supplies have the incorrect strap installed on the transformers ofCyberex P/N [Part Number] 30-80-56620 which potentially can lead to the transformer being loose and can causefailure of the power supply. Per the manufacturer, the band should have been made of stainless steel but thebands on the installed transformers were made of carbon steel and a corrosion resistant coating.
The details of thepotential failure of the power supply and the root cause are being evaluated and will be documented in the finalreport."UCI [United Controls International]
reviewed all the orders that were supplied to the customers and determined that two UCI orders are affected and the customer was notified on the day the issue was identified."

0411712014 U.S. Nuclear Regulatory Commission Operations Center Event ReportPagre 2"SUMMARY:
UCI issued a certificate of conformance to PSEG for S/N: 003967-03-0001 thru 0003 on December22nd 2012, to be used in safety related applications where seismic is the only design basis event. During the pre-installation testing in February 2014, PSEG identified loose transformers and a loud noise frequency whine and thepower supply boards were returned to UCI. Below table lists the details of the power supplies that were returned toUCI."On February 2nd 2014, UCI has initiated part 21 evaluation to determine the root cause for the failure andevaluate if a defect existed.
During the evaluation, it was determined that the transformer strap band installed onCyberex P/N 30-801-56620 transformer at the location T501 should have been made of stainless steel but thestrap band on these power supplies was made up of zinc plated carbon steel. Due to this material difference, thetransformer warped and it was evident it became loose."The installation of the incorrect strap bands on the transformer apply to only one batch of manufactured PCBassemblies.
The manufacturer addressed this issue since this was discovered and this was verified by UCI. UCIdetermined that the order along with the boards that failed pre-installation
- testing, were the only boards affected bythis issue. The customer PSEG was notified on March 13th 2014 and the initial notification letter to NRC was senton March 19th 2014."The above mentioned power supplies were recalled from PSEG and two power supply boards of S/N: 003996 0002 and 003996-01-0003 are currently at UCI for evaluation and rework. However the S/N: 003996-01-0001 board has not yet been returned to UCI by PSEG. UCI performed an XRF analysis on one of the affected powersupplies per part number lot and on UCI control samples to confirm and compare the material of the transformer strap bands."EFFECT OF THE DEFECT: The installation of the incorrect transformer strap band resulted in the loosening ofthe transformer from the band. When installed in the system, the transformer might become loose and cause aloud whining noise. The installation of the incorrect material band on the transformer might lead to loosening of thetransformer and causes whining noise when installed but no functional test failure will be observed.
- However, theloose transformer affects the safety function of the item during or after seismic event due to loss of structural integrity.
"CORRECTIVE ACTIONS PERFORMED:
A UCI corrective action # CAR 14-14 was opened to document theissue found and the corrective and preventive actions taken. As a result, UCI will create two new Commercial Grade dedication procedures for P/N: 41-01-596701 and 90-41-974313 to include the material verification of thetransformer bands installed on these power supplies.
These new procedures will be used for the existing andfuture orders of these part numbers."All the affected power supply boards except S/N: 003996-01-0001 are currently at UCI undergoing rework toreplace the transformer of the incorrect material strap band with a transformer of the correct (stainless steel) strapband. After rework, dedication will be performed per new dedication procedures as specified above."Notified R1 DO (Burritt) and Part 21 Group via email.

During the evaluation, it was determined that the transformer strap bandinstalled on Cyberex P/N 30-80-56620 transformer at the location T501 should have been made ofStainless Steel but the strap band on these power supplies was made up of Zinc plated carbon Steel (SeeTable 3 for material test results on one of these boards).
Due to this material difference, the transformer warped and it was evident it became loose.Page 2 of 12United Controls International 0 205 Scientific Drive 0 Norcross, GA 30092 APR/17/2614/THU 03:07 PMFAX No,P. 005EER-14-6216-01, Rev: 0Per the manufacturer's attached email (Attachment 1), the installation of the incorrect strap bands on thetransformer apply to only one batch of manufactured PCB assemblies.
The manufacturer addressed thisissue since this was discovered and this was verified by UCI. UCI determined that the below mentioned order along with the boards that failed pre-installation

The above mentioned power supplies were recalled from PSEG and two power supply boards of S/N:003996-01-0002 and 003996-01-0003 are currently at UCI for evaluation and rework. However the S/N:003996-01-0001 board has not yet been returned to UCI by PSEG.

These boards emit a loud high frequency whine during normal operation.
Some of the noise is directly from the large transformer.
The noise can be quite irritating especially during a bench test or when the system cabinet is open.A transformer that is loose will emit mare noise. This Is the only effect that I know of, but since thenoise can be quite irritating, the quieter the unit is the better.The power supply will still deliver the correct voltages.

Re: P/N: 41-01-596701 Transformer Mounting IssuesGood afternoon, Sameera.RBB response:
I think that if someone encounters a transformer on an older board that is loose to the extent ofcausing excess vibration, the transformer should be replaced.
If the transformer is not loosethen the unit will operate reliably.
I have not typically seen the band break except on very old units where the transformer wasvisibly overheated or in shipping where the unit likely experienced severe shock.Have a great rest of the day!Regards,Page I I of 12United Controls International 0 205 Scientific Drive 01 Norcross, GA 30092 APR/17/2014/THU 03:09 PM FAX No, P. 014EER-14-6216-01, Rev: 0Attachment 6Front:To:
