Manufacture, Dependable Power System (DPS), PN 20050061 (Date Code 2007)

Dear Sir,

This letter provides notification per regulation I0CFRPart2lconcerning the discovery through testing and evaluation of (4) four UPS System motherboards that reported to have failed pre-service inspection prior to installation into a UPS system at Southern Nuclear- Farley Station Unit I TDAFWP UPS "B" Section.Trentec (now known as QualTech NP) provided these safety related motherboards for installation on a UPS system manufactured by (OEM) Dependable Power System.

Background:

The (4) four questionable motherboards were returned to QualTech NP for testing and evaluation to determine operability of their safety function including fit, form and function for use within the UPS System. Southern Nuclear Condition Report, CR2010109013. states "Motherboard (DPS 20050061, SN 354, Trentec Tag # 7T55201 SNO1) with different valued resistors and or different locations than original motherboard..." QualTech NP developed a new dedication plan (DPS2010.0 Rev. l) to evaluate the returned motherboards for fit, form and function. The plan involves visual inspection verification -QualTech NP compared the returned boards to DPS BOM lists to identify any differences; and functional performance verification-the functionality of the items were verified by performance testing as factory Go/No Go board tests using a UPS system to the parameters defined in the existing referenced dedication plans. 11/08/2010 MON 13:48 FAX 5135283845 2003/028 Page 2 of 2 Observation during Evaluation: Visual inspection of the motherboards found one resistor installed in the wrong location. Performance testing of motherboards found the resistor installed in the wrong location affected the safety function of the UPS system.The motherboard with the resistor installed in the wrong location failed to operate during performance testing. The motherboard was reworked by original equipment manufacturer (OEM) who removed the resistor in question and re-installed it in the correct location. The repaired motherboard was performance tested and found acceptable for safety function for use within the UPS system.Extent of Condition: QualTech NP has reviewed its customer project / PO files and has determined the dedicatedUPS system (2)and these this motherboards with Date Code 2007 have only been provided to Southern Nuclear-Farley Station Unit I & 2 (total quantity-4). Southern Nuclear -Farley Station Unit I &2 has two (2) motherboards in service. QualTech NP has addressed the dedication and testing of motherboards by the developing a new dedication plan (DPS2010.0 Rev. 1). Southern Nuclear has reviewed and .approved this new plan.Conclusion & preventative Action: QualTech NP's conclusion is that the resistor in the wrong location on the motherboard caused the UPS system not to operate during performance testing and established the equipment would not perform its intended safetyfunction.. After rework, relocation of the resistor, and retesting the UPS system became operable and was performing its safety related function. QualTech NP has completed testing, evaluation, and repair of motherboards, no further action is required.Regards, Kurt Mitchell General Manager Attached: QualTech NP I OCFR Part 21 Report QualTech NP Evaluation Report QualThch NP 4600 East Tech Orive Cincinnati, OH 45245

The defective motherboards reported to have failed pre-service visual inspection prior to installation into a UPS system at Southern Nuclear -Farley Station Unit 1 TDAFWP UPS "B" Section.The Auxiliary Feedwater (AFW) system for each unit consists of two motor driven pumps and one turbine driven pump. The TDAFWP UPS for each unit has an A and B section for system redundancy, with one motherboard used in each section. The motherboards currently installed in the Farley 1 TDAFWP UPS B section and Farley 2 TDAFWP UPS B section do not havethe suspect date code. (total of two).The use of a defective motherboard for scheduled component replacement for the UPS would cause a start-up delay. Together with a single failure of one of the motor driven AFW pumps would leave the remaining motor driven AFW pump to ensure the reactor coolant system was properly cooled via the steam generators during emergency condition. However, two of the three AFW pumps are required to satisfy the flow demand for the most limiting associated design basis accidents and transients, i.e., feedwater line break, main steam line break, and loss of main feedwater. Accordingly, the flow demand is needed to mitigate the consequences of these events which can result in over-E£-I 11/08/2010 MON 13:48 FAX 5135283845 2oo5/o28ý10 CFR 21 Report Dependable Power System (DPS) Motherboard Failures for use in the Turbine Driven Auxiliary Feedwater Pump Uninterruptible Power Supply pressurization of the reactor coolant pressure boundary, and to prevent uncovering the reactor core and potential radiological releases.

3.0 INTRODUCTION

The subject Southern Nuclear purchase orders (reference section 2.0) required dedication and the supply of RI Dependable Power Systems (DPS) parts listed in Table 3.1. After delivery to Plant Farley, this equipment i was returned to QualTech NP for the investigation of possible design or fabrication errors.Three Condition Reports were generated by Southern Nuclear against the QualTech NP supplied RI equipment. They are summarized as follows: CR2010109013 Motherboard (DPS 20050061) -different valued resistors &/or different locations than original motherboard; discussed between Farley & DPS CR2010110041 Rectifier/Charger Control Board (DPS 20010004) -R52 was a different value, R104 was addedto the board; ICI, IC13, IC16, & ICI 7 had one pin soldered that was previously cut off CR2010110060 Evaluation of CR2010110041 for Part 21 Reportabiiity Of these three reports, only two identified discrepancies & only one of these two was specific to the findings. However, based upon the concerns for design control by the manufacturer, QualTech NP is treating all circuit boards consistently with additional verification activities outlined in the Quarfech NP Test Plan DPS2010-I Rev. 0 (see Section 2.0) for both the current returned items under the referenced RAs and for all future sales as clarified herein.The email dated 7/27/2010, from John Avery, Contracts Agent, is the formal notification from Southern, RI Farley Nuclear plant that there is a problem with the circuit boards used in the UPS system. Note that no failures of boards have occurred in service due to manufacturing defects or workmanship. The problems were identified during pre-service inspection at Plant Farley.On July 27, 2010, George Kenney (QualTech NP Cincinnati QA Manager) had a conversation with John Avery and Floyd Vanderian, AFW System Engineer, to discuss problems with circuit boards reported during a sales meeting and by CR 2010109013. The first problem with the boards was noted over two (2) years ago. There was no CR created, nor was Trentec informed of the problem. CR 2010109013 was written within the month but not formally reported to Trentec/QualTech until July 27, 2010. During the conversation Southern could not identify any problems in writing found on the circuit boards.Floyd Vanderian, informed John Avery and George Kenney that they, Southern, to address the problems with the boards, bypassed Trentec and went directly to the suppler of the UPS. Southern at the time could not identify what action was taken by the manufacture. According to Bill Speth of DPS (OEM), he discovered that the defective motherboard was manufactured incorrectly (board manufactured in 2007) while at Floyd Vanderian's desk at Farley (April 2010 per Bill Speth), prior to intended installation. 3.1 Description of Equipment Table 3.1 provides descriptions of the customer returned parts that were re-tested per the original test methodology and then installed in QualTech's qualification specimen to verify operability in a UPS system.TABLE 3.1 Item#f Dependable Power Systems Inc.

Rectifier / Charger Board, PN 20010004, Trentec Tag # T8236 1OB SN 01, DPS SN 10452 was received with shipping/handling damage. SWI was replaced by Bill Speth of DPS with QualTech NP witnessing, prior to proceeding. (Toggle switch stroke worked only in one direction & could not be fully moved to opposite position.) 11/08/2010 MON 13!50 FAX 5135283845 2011/028 QualTech NP Report # DPS2010.0 Rev. 1 PG 6 2. Alarm / Meter Board PN 20040014, Trentec Tag #9 T82361OG SN 01, DPS SN 40352 was received with shipping/handling damage. SW7 was found to be defective. (Push Button Switch was non-functional, cover rotated 90 degrees from top to side.) This switch will be replaced upon receipt of replacement part.3. Mother Board PN 20050061 Trentec Tag # 7T55201SN 01, DPS SN 354 had R43 mis-installed into R42 location. In this mis-configured condition, R43 would prevent the SCR from gating thus if installed would not have permitted the UPS section to operate. Note: per Bill Speth of DPS, who found the error while at APC, this board was not taken to the UPS for installation as it was discovered while at the APC engineer's desk. The resistor was removed & re-installed in the proper R43 location by Bill Speth prior to proceeding. Functional Performance Verification -The functionality of the items were verified by performance testing as factory Go/No Go board tests to the parameters defined in the existing referenced dedication plans in table 3.1. These were "bench" type tests performed by Bill Speth using DPS test fixtures and performed by Bill Speth with QualTech NP witnessing. All boards (except Tag # T82361OG SN 01)were tested and all passed the functional tests.Note: Motherboards have tin plated connectors. In all cases, the motherboards, prior to installation &successfid tesiing, had an eraser (or equivalent) applied to the sides of the connector pins nearest the PCB edge to remove any possible oxidation prior to insertion. Failure to do so can result in unexpected.intermittent connectivity with indeterminate operating results. DPS recomnniends using the pink/red eraser at the end of a pencil or the larger pink/red hand held eraser.Other than Tag # T823610G SN 01, all boards were then tested within the qualification Test Sample UPS system to further confirm fit and complete electrical operability. In all cases the tested boards performed properly and met their respective fit, form, & functions with the UPS system functioning normally.Inspection verification -QualTech NP compared the returned boards to DPS BOM lists to identify any differences. Any differences in the BOMs and the boards were identified and either documented as BOM documentation errors or were justified. Due to time constraints and high confidence from successful testing within the operating Qualification Test Sample UPS, QualTech NP limited this activity to one of the most densely populated PCBs, the Alarm Meter Board, the board previously having only a resistance test, the Mother Board, and a Rectifier/ Charger board with the following findings: Review of Atarm/Meter Board PN 20040014, DPS S/N 40367 Trentec Tag # T86201G SN 01: I. Missing ICI15 (4020 Ripple Counter) -Missing so that horn doesn't go off per APC's request 2. Missing C88 (0.01 uF 1 OOV Capacitor ) -redundant noise suppression Substituted IC20 (drawing calls for OP07, used TL071ACP) -different mfir but equivalent Added D34 (1N4004) -not required but no impact on fit, form, and function 3. Not on BOM list but quantity shown in BOM is correct (LED 22, 23, &.25)4. R35A labeled on PCB as R42A -silk screen error 5. BOM's DE4 (1K 1% 1/4W resistor) -BOM typo (Qty of 3 accounted for with R20, R64, &R67)6. BOM's ZD5 (1N4744A 15V 1W Zener Diode) should be ZD6 (ZD5 also called out as 5W on next line in BOM, the 5W part is correct) -BOM typo 7. SW6 has different settings than qualification sample (Side A) -PCB dependent setting a.TS-A, I to 5 set as On, Off, Off, Off, On b.SN 40367 set as On, On, On, On, Off 8.

TS-A, I to 5 set. as Off, Off, Off, Off, On b. SN 40367 set as On, Off, Off, Off, On Each of the above had no impact on fit, form or function. 11/08/2010 MON 13!50 FAX 5135283845 2012/028 QualTech NP Report # DPS201 0.0 Rev. I PG 7 Review of Motherboard PN 20050061, DPS SN 354, Trentec Tag # 7T55201 SNO1:.R43 was mis-installed into R42, corrected by Bill Speth of DPS Motherboards have several resistors that work within a range of values (thus can change from time to time without impacting operability).

1. R41 can be any nominal resistor between 200 ohms & 1000 ohms 2. R30 -R32, & R38 can be any value from a jumper to 1.0 ohms and any wattage up to 2W. The purpose of these resistors are to fail when another component fails, saving the clad on the PCB.Jumpers & larger wattage resistors could permit PCB's copper clad to fuse as a secondary failure but does not affect operability.

This scenario of the manufacturer's approved variance is valid for this range of resistor values anywhere in the system.3. R43 can be any equivalent nominal resistor between 45 & 55 ohms with 1/2W equivalent rating.Each of the above had no impact on fit, form or function.Review of Rectifier/Charger Board PN 20010004, DSP SN 10452, Trentec Tag- T823610B SNOI: I.

This is no longer required due to APC no longer wanting units used in Hot Standby. To conserve battery life, APC is using the units in cold standby mode. For all other applications of these ICs the pin 6 may be removed but is not required to be removed.Each of the above had no impact on fit, form or function.In all PCBs and pertaining to all resistors:

parallel. equivalent values with at least the equivalent wattage shown are acceptable without notation on drawings or the BOM. Tighter tolerances are always acceptable. 5.0

SUMMARY

What was referred to in the APC emails as "poor quality" is commonly referred to in the industry as"manufacturing deviations" and as "revisions to the design" or "alternative components". In all cases, the provided service parts are not provided as "identical" but as "equivalent". This methodology of substituting electrically equivalent sub-components is common practice for a commercial manufacturer R and to be expected. Documented design justification of sub-components is generally not a requirement even in the Nuclear industry unless said changes impact the safety function (ie alternative manufacturer of a relay that could potentially change the seismic full operability levels). For example, alternative RI brands of semiconductors, resistors values within the manufacturer's accepted ranges of values or wattages, resistor values selected by test results, etc. are all acceptable when GSTERI E-95002 defines these parts as seismically insensitive. In addition, similar components were seismically qualified elsewhere on the same or other PCBs within the qualification sample, & qualification sample was fully operable using these boards with these different sub-components. Thus it is QualTech NP's conclusion that evidence of operability within the parent component (the qualification sample or equivalent) is sufficient evidence of fit, form, & function which meets the requirements of dedicated commercial grade items that are intended for use in safety related applications. R, 11/08/2010 MON 13:50 FAX 5135283845 2013/028 QualTech NP Report# DPS2010.0 Rev. 1 PG 8 QualTech NP thus met the quality and technical requirements of the original POs for these printed circuit R1 boards.QualTech NP concludes that the sole finding of one resistor mis-located in one motherboard merits a Part rI 21 reportable event even though the defective PCB was not installed at the plant. (Note: Even if the board had been installed, the section of the unit would not start as the SCR's gate would not function.Since the unit must be operating at all times when the plant is operating, the defective board would never have allowed the section (1/2 of the redundant unit) to return to operability. Regardless, the supply of a RI defective component which prohibits the host from performing its Safety Function justifies a Part 21.)To prevent recurrence, the motherboards will be functionally tested in a working DPS UPS prior to upgrading to Safety Related. The issue was also addressed via QualTech NP Non-Conformance Report 1 10-78 regarding contract 7T552 which will be provided to Farley separate from this document.After testing all other returned spare part boards (including other motherboards), all functioned properly RI when installed in the qualification sample.QualTech NP has also identified through communication with. Farley personnel & DPS that the B section RI of UPS in Farley Unit I has seen ambient temperatures which apparently exceeded the service temperature for which the unit was designed (50C external ambient conditions & 55C internally). About a year ago (July 2009), the exhaust fan/blower for the room in which it is installed failed resulting in an extended over-temperature condition. The high heat conditions were significant enough during the replacement of the fan/blower that time limits have now been set for personnel time in the room.QualTech NP understands that the UPS was operating during this time period and that specific operating half of the redundant UPS failed shortly thereafter. For this unit to be restored to a reliable operable condition, all temperature sensitive sub-components need replaced at the same time to preclude temperature stressed components from failing and damaging, as a secondary failure, components recently replaced.This room is continually operating at an ambient condition near the maximum rated condition which will effectively provide real time accelerated aging of the components. QualToch NP and the manufacturer, DPS, strongly recommend the following changes: i. Change the feed wire as shown in the photos below to preclude damaging a motherboard as a secondary failure when an SCR fails: Left photo is section A of the Qualification Sample and is the desired configuration of wiring. Right photo is section B of the Qualification Sample and is the wiring configuration that can damage the mother board as a secondary failure. Both attachments were qualified.

2. The manufacturer recommends use of faster SCRs (faster turn off times) to allow higher operating temp, turn off times increase with temp, so faster turn off times give more margin &makes the commutating capacitor cover a wider operating temperature range (DPS PN 61461601 to replace PN 6123 1601 inverter SCRs 4, 5, 14, & 15).

11/08/2010 MON 13:51 FAX 5135283845 2014/028 QualTech NP Report# DPS2010.0 Rev. 1 PG 9 3. Either move the UPS system(s) to a cooler area or lower the ambient temperatures to 80F or less as the "normal" temperature. As a rule of thumb, every 5C/9F temperature increase during"normal" conditions will effectively "halve" the life of the product. During a recent QualTech NP visit to the installation site, an ambient temperature of 106F (41C) was recorded with 113F (45C) at the exhaust fans of the UPS. Using QualTech NP's copy of System 1000 material database system, the Design Life for these aluminum capacitors, at 113F continuously, becomes 2.1 years (with a safety factor of 4). The units will operate at these temperatures but the expected replacement time for temperature sensitive components (such as aluminum electrolytic capacitors) will be greatly reduced.4. To improve the cooling of the system using the exhaust fans installed. Manufacturer strongly recommends sealing off the open vent at the top of the unit which allows the air flow to short cycle. All air should be pulled through the base of the UPS, by the components and out the top.With the top vent open, air can flow from the room, into the vent at the top, into the fan, & back into the room without doing any cooling of the system. Note that the temperature inside of the UPS is likely much higher than the I 13F read at the exhaust of the fans since the fans are cooling air from the unit by mixing that air with the room air prior to exhausting it.QualTech NP considers fit, form, & function as being satisfied by the functional test results, even when parts change from the original designs.QualTech will return the PCBs with a C of C for the tested items, stating that the earlier dedication is still valid for all PCBs except those repaired. The repaired PCBs were re-dedicated to the degree required to provide equivalent replacement items for use in the QualTech provided UPS systems.Future sales of these boards will provide the option of having Qual'l'ech NP perform a sub-component by sub-component configuration check of the board against each board's BOM. This would result in documenting BOM errors and/or justification of differences on each board, if this level of documentation is desired by Farley. 11/08/2010 MON 13:51 FAX 5135283845 2015/028 QualTech NP Report# DPS2010.0 Rev.

1. JPI2 called TPI2 in BOM -ROM typo 2. R 12 per BOM is 220 Ohm Resistor but installed 100 olnn -RI 5 will adjust out and difference

3. R30-R.32 & R38 can be any value from a jumper to 10 ohns and any wattage up to 2W -The purpose of these resistors are to fail when another component fails, saving the clad on the motherboard.

Jumpers & larger wattage resistors could permit motherboards clad to fuse as a secondary failure but does not affect operability.

4. R40 is shown as R46 ott ROM (R46 on PCB is empty) -BOM typo 5. R41 per BONI is I K but had 200 Ohm resistor installed

-Per Bill Speth, R41 car be any nominal resistor between 200 & 1000 ohms.6. R43 per BOM should be 47 olun but had (2) 100 olors in parallel-Per Bill Spreth, R43 can have any equivalent nominal resistor beiween 45 & 55 ohms %vith 1/2W equivalent sating.BOM Jumpers Cl A Y C2 B Y C3 C Y C4 D Y CS E Y C6 F Y (3 Y 11 Y I N/A J Y K Y t. y/A Y N Y COM LOOP P Y Q Y R Y S Y T Y U Y V Y W Y empty .Dl empty FUI empty D2 empty FUJ2 N/, (104J10OV) 0.hP, OOvD3 (IN4004) FU3 N1, (10410OV) .luF, 100v 1)4 (1N4004) "FU4 RE empty D5 (IN4004) FU5 em (104JI00V) O.luF, IOOvD6 empty D7 (IN4004) IA 400V D8 empty D9 (IN4004) IA400V DI0 empty DiI empty D12 empty D13 empty A pD.
