Dear Mr. Keppler,

This letter serves to confirm our phone conversation with your office of July 5, 1983. s During the qualification testing of aged electrical equipment for the Perry Nuclear Project certain anomalies occurred. These anomalies were in apparatus which had been artificially aged using Ahrrenius methodology with elevated temperature aging. The equipment involved was A-C and D-C low voltr.ge motor starters' in motor control centers. x. N s We have searched our records and notified the licensees whom our, records indicate have purchased this apparatus for safety related Class 1E application. We would like to further amplify the point that these conditions were obtained from artificially aged apparatus for qualification,N q, for IEEE 323-1974 and not based on any field experience. There s "s is great probability that the conditions described are induced by molding shrinkage caused by the very high temperatures of s artificial aging. We would like to further point out that we have notified all plants s known to contain this apparatus even though the plant was not ~ licensed under the requirements of IEEE 323-1974. There are several anomalies listed below followed by a listrof'those riotified as known purchasers of that type of equipment for Class 1E use. 'A 8307100194 830708 PDR ADOCK 05000249 .'.

EATON/ CUTLER-HAn#4ER PRODUCTS MOT 0li CONTROL CENTERS 480V A-C NOTICE OF ANOMALY OVERLOAD RELAYS USED WITH NEMA SIZE 1 AND 2 MOTOR STARTERS MOUNTED 90' CCW FROM VERTICAL Gentlemen: E"' SN. ,During recent qualification testing for plants being reviewed under lEEE323-1974, certain anomalies have occurred which we feel should be brought to your attention for evaluation under 10CFR21. Our records show that you have motor control centers containing NEMA size 1 and 2 motor starters with thermal overload relays mounted 90' -counterclockwise from vertical on a vertical panel. Our records f urther indicate that some of these overload relays are in safety-related (Class IE) apparatus. The discovered anomaly in these sizes and mounting configuratloa is .that after a period of time in elevated ambient temperatures, in some cases, the relay may f all to trip on overload conditions. Our company is not in a position to evaluate whether the anomaly found in taase relays would cause a _ substantial safety hazard within the . meaning of 10CFR21 regulations, and will rely on the licensee's judgement concerning the need for reporting the matter to the NRC. Exact timing or temperatures, when this could be expected to occur, are difficult to determine since percent' loading, percent on-time and ambient temperature all ef fect this heat related anomaly. If it is desired to insure f uture operab!!Ity and to check f unction, we would recommend periodic exercising of The trip f unction of these devices. Such exercising should prevent f uture occurrence and may correct this anomaly if-It.has already occurred. We would recommend this check be done at f uel replacement time or at 18 month intervals, whichever occurs first using a minimum of three trip-outs per check. Either mechanical or thermal trip may be used to exercise the j mechanism. The recommended procedures are attached. Cutler-Hammer Products-

i THERMAL EXERCISE OF SIZE 1 AND 2 OVERLOAD RELAYS I Periodic exercising of the size I and 2 overload trip mechanism when mounted 90* CCW position on a vertical panel is required to insure opers.bility. Checking this function at least every 18 months using a minimum of three trip-outs per check is recommended. Trip-out can be accomplished as follows: 1. Disconnect power f rom motor control center starter unit. Open unit door. 2. Disconnect B phase motor lead from the center terminal of the overload relay. 3. Use a portable power supply

to provide 300% of motor f ull load current and apply this current to two adjacent heater elements in series.

Series heaters in center and either outside phase (B and A or B and C) DO NOT SERIES THE TWO OUTSIDE PHASES (A and C) because this will pass current through the motor as well as the heater coils. Use portable clip leads. 4. Overload relay should trip in 2 minutes maximum (audible and trip flag indicator on relay or measure contact change of state). 5. Remove portable supply and leads and proceed to next starter unit repeating steps 1-4. 6. Af ter a minimum of three minutes or after all overload relays in a center have been tripped, return to first one; reset by depressing reset button and repeat tripping procedures. 7. Do thl's until all overload relays have been tripped three times. 8. Replace the center motor lead connection on all overload relays. 9. Replace the overload relay if it falls to trip or reset.

N'JTE : Portable power supplies for overload relay or circuit breaker tripping can be obtained from MULTI-AMP CORP., 4271 BRONZE WAY, DALLAS, TX 75237. t-

MECHANICAL EXERCISE OF SIZE 1 AND 2 OVERLOAD RELAYS Perloalc exercising of the size 1 and 2 overload trip mechanism when mounted 90* CCW position on a vertical panel, is required to insure operability. Checking this f unction at least every 18 months using a minimum of three trip-outs per check is recommended. Mechanical exercise of the overload relay at the job site can be accompl!shed as follows: (Reference Figure 1) 1. Disconnect power f rom the motor control center unit. Open unit door. 2. Remove the two outer heater coils (poles 1 and 3). 3. Loosen the two outer thermal element mounting screws 1 to 1-1/2 revolutions. 4. Using the thermal element screws as pivots, tip the thermal elements in pole 1 and 3 toward the contactor (or toward the line side terminals f 6r the case of component overloads). This disengages the trip levers from the thermal elements thus effecting a trip-out. Monitoring the overload relay contacts during this procedure should indicate a change of state as the overload relay trips. _______== NOTE: This mechanical trip method is not recommended for the center pole because fine teeth of a molded coupling underneath this pole may be damaged on reassembly when proper care is not exercised. 5. Hold pole I and 3 thermal elements in place by hand and fully depress the reset button. Upon release of the button, the overload contacts should return to the reset state. 6. Replace the overload relay if it f alls to trip or reset. 7. Repeat step 4 and 5 for three operations. l CAUTION: USE CARE WHEN RE-TIGHTENING THE THERMAL ELEMENTS. These are held-in by self-threading screws and can be stripped if excessive torque is applied. t l l DOWI4 l LEVE R (B) TRIP i TMERMAL ELEMENT (m).\\h'\\ '\\ NN\\sgN'dNjf'[p \\\\ 3 i / A i g'-[ k 8 CouPLtM q \\ \\ .E-N ' f b l l / j '/4 .N 6.'NN\\lN\\.N '\\','N\\s.\\\\'N'.'d i.'1,-. l . \\ s. /. r,- s s s Ns,N / x .j j s fU C 'f l i = tti Y_/f J? j --- - tu = NNN'\\N, s.

EATON CORPORATION / CUTLER-HAMER PRODUCTS 125V OR 250V D-C MOTOR CONTROL CENTERS REDUCED VOLTAGE MOTOR STARTERS NEMA SIZE 1 AND 2 NOTICE OF ANOMAllES ACCELERATION TIMING CIRCulT Gentlemen: ,During recent qualification testing for plants being reviewed under o e IEEE323-1974, certain anomalies have occurred which we feel should be 8" brought to your attention for evaluation under 10CFR21. RFIAY TIMING Our records show that you have D-C motor control centers containing NEMA size 1 and 2 reduced voltage motor starters. These starters contain accelerating relays, part number 10-3486 (#538) for the size 1 and part'numi.ar 10-3487 (#673) for the size 2. Our records further Indicate that some of these accelerating timing relays are in safety-related (Class IE) apparatus. The fIrst anomaly discovered was that the first step timing was reduced after the seismic event to 35% of the preseismic event setting. The overall timing is relatively unaf fected by seismic - events. Our company is not in a position to evaluate whether the anomaly found in these relays would cause a substantial safety hazard within the meaning of 10CFR21 regulations, and wIlI rely on the iIcensee's judgement concerning the need for reporting the matter to the NRC. The recommended maintenance procedure af ter a seismic event is attached. CAPACITOR MOUNTING . A second anomaly was discovered in the mounting of the capacitor for the RC network. The capacitor part numbers arer 42-143 (25Mf1)-300V), 42-143-2 (75 MFD-150V), _42-143-5 (50 MFD-300V) and 42-143-6 (150 MFD-150V). Cutler-Hammer Products

'Page Two (Name of Power Company) May 16, 1983 'It is highly uniIkely that your plant contains this condition since the cause was s reduction in length of the capacitor which most likely did not occur until af ter the centers in your plant were shipped. The nature of the anomaly was that due to improper mounting, the capacitor was damaged causing f ailure of the dielectric test to ground. This began to occur when the capacitor length was shortened and an improper stop bracket was used. Most Iikely your plant has capacitors mounted per Figure 1 on the attached w: th the 8" capacitor. There is no problem with this g -arrangement. If you have the Figure 2 bracket with the shorter capacitor, it should be replaced with bracket part number 55-496 per Figure 3. The capacI-tor should also be replaced. The capacitor part number depending on the capacitance and voltage rating are: 42-143 (25 MFD-300V), 42-143-2 (75 MFD-150V), 42-143-5 (50 MFD-300V) and 42-143-6 (150 MFD-150V). Our company is not in a position to evaluate whether the anomaly found in the capacitor mounting would cause a substantial safety hazard within the meaning of the 10CFR21 regualtions, and will rely on the licensee's judgement concerning the need for reporting the matter to the NRC.

Contact Poles, stamped i with an "R" or a similar marking, are separate, self con-l tained, sealed units which become either normally open or normally closed contacts depending upon how they are in-serted into the molded, insulated deck. The Rear Deck and Magnet will accept up to four rear contact poles in any com-bination, and to this unit a frcnt deck may be added to CARE provide a total of eight poles. These devices require no mechanical maintenance or lub-rication under average operating conditions. The cover plate APPLICATION must be securely positioned for proper contact action. The relay is designed for adjacent mounting on a vertical plane using 2 or 3 No.10 mounting screws, and it may be CONTACT POLES mounted at a 90* position (contact poles horizontal) if nec.
