Pu … This Part 21 was received via facsimile</br>Pursuant to 10 CFR 21.21 (d)(3)(ii), Fairbanks Morse Engine is submitting a written notification on the identification of a defect that is considered to be a substantial safety hazard.</br>(II) Identification of the facility, the activity, or the basic component supplied for such facility or such activity within the United States which fails to comply or contains a defect.</br>Facility:</br>Duane Arnold Energy Center </br>Basic component which fails to comply or contains a defect:</br>Woodward governor actuator model EGB13P, part number 16403190, Woodward part number 9903-561 for Fairbanks Morse Engine Emergency Diesel Generator (EDG).</br>(iii) Identification of the firm constructing the facility or supplying the basic component which fails to comply or contains a defect.</br>Fairbanks Morse Engine</br>701 White Avenue</br>Beloit, WI 53511</br>(IV) Nature of the defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply.</br>Nature of defect:</br>Per Woodward service bulletin 01393 dated January 2007, a pivot pin within the governor actuator was manufactured from incorrect material. The subsequent case hardening of the pivot pin made from incorrect material resulted in through hardening, making the pivot pin more brittle.</br>Safety hazard which could be created by such defect:</br>Per Woodward service bulletin 01393, a potential for pivot pin fracture exists which would result in the governor actuator going to the minimum fuel setting. The EDG would not be capable of carrying load under this condition.</br>The inability of an EDG to carry a load during a design basis event would be considered a loss of safety function.</br>(v) The date on which the information of such defect or failure to comply was obtained.</br>Fairbanks Morse Engine received Woodward service bulletin 01393 on 1/11/07. Duane Arnold Energy Center was notified of this situation via e-mail dated 1/12/07.</br>(vi) In the case of a basic component which contains a defect or fails to comply, the number and location of all such components in use at, supplied for, or being supplied for one or more facilities or activities subject to the regulations in this part.</br>The list of potentially affected governor actuators identified in Woodward service bulletin 01393 contains only 3 units (serial numbers 14693610, 14687576 and 14699005) that were purchased by Fairbanks Morse Engine on purchase order 1079037-I. All 3 units were sold to Duane Arnold Energy Center and had not been assembled to the EDGs.</br>(vii) The corrective action which has been, is being, or will be taken; the name of the individual or organization responsible for the action; and the length of time that has been or will be taken to complete the action.</br>The 3 units were repaired at Woodward on 1/18/07 by replacing the though hardened pivot pin with one that was from a lot that was verified via destructive analysis to be hardened to the properly case depth. All future lots of pivot pins will have case depth measurements taken to ensure proper case depth.</br>(viii) Any advice related to the defect or failure to comply about the facility, activity, or basic component that has been, Is being, or will be given to purchasers or licensees.</br>The need for repair of the 3 units was communicated to Duane Arnold Energy Center on 1/12/07. The repaired governor actuators were returned to Duane Arnold Energy Center on 1/26/07. to Duane Arnold Energy Center on 1/26/07.
