DEFECTS AND NONCOMPLIANCE PART 21 - POTENTIAL DEFECT IN MOTORS SHIPPED TO DTE ELECTRIC COMPANY The following is excerpted from a report received by fax:

"NUCLEAR NONCONFORMANCE REPORT "1. CUSTOMER: DTE Electric Company, P.O. BOX 44440, DETROIT MI 48244 "2. PURCHASE ORDER: 4700670925 - QTY 2 "3. PART/COMPONENT NAME: AC MOTORS "4. PART/COMPONENT#: B1038686-010 T1/DTE P/N 100309425 and B1038686-010 T2/DTE P/N 100309425 "5. QUANTITY ON HAND - 1 SHIPPED-2 "6. LOCATION OF ALL UNITS: Motor in service at DTE, Enrico Fermi Power Plant 2 (Qty 1) and at Baldor Gainesville Motor Plant (Qty 1)

"7. DATE NONCONFORMANCE ASCERTAINED: March 13, 2014 "8. DESCRIPTION OF DEFECT/NONCONFORMANCE: This is a reportable 10CFR21 notification because we believe it is possible that the B1038686-010 T1, 1E motor shipped by Baldor Electric, contains a design where the shaft journal is not long enough to allow the proper fit between the motor shaft and the o-ring of the inpro seal rotating element.

0411012014 U.S. Nuclear Regulatory Commission Operations Center Event Report Pame 2 "The motor (BI038686-010 T2) returned for evaluation under RA310488951 was in response to the inpro seal separating. Upon inspection Baldor has determined the shaft journal is not long enough to allow the proper fit between the motor shaft and the o-ring of the in pro seal rotating clement.

"9. CORRECTIVE ACTION TAKEN: Baldor has notified DTE Electric Company's Quality Assurance of our findings. Through them we have initiated replacement of the motor identified as located at DTE, Enrico Fermi Power Plant 2.

"A review was completed by design engineering to determine this design issue has only occurred for the Specification ID B1038686, of which Baldor has only shipped the 2 motors identified above. The design of the shaft/inpro seal fit has been completed to correct the issue.

"10. ANY ADVICE RELATED TO DEFECT/NONCONFORMANCE: Separation of the rotating element from the in pro seal obviously reduces the full effectiveness of the in pro seal. However, if this were to occur, the motor is still functional. Baldor has confirmed the motor with a failed inpro seal as received is still equivalent to IP55. Grease from the DE bearing will still be retained as intended, and water ingress into the motor would only occur if sprayed directly. Baldor recommends continued use of B1038686-01OT1 until the next outage unless direct spray is expected. B1038686-010T2, which is currently in Baldor's possession, will be repaired by changing the rotating assembly. Baldor has notified DTE that we will be manufacturing a complete motor per the revised bill of material to replace B1038686-010TI which is currently in service.
