Woodward 2301A and DRU with unapproved supplier IC P/N: 9903-303, 9903-337, 9903-444 & 9903-470 DISCUSSION:
Engine Systems Inc. (ESI) began a 10CFR21 evaluation on 8/14/09 to evaluate the use of an integrated circuit (IC) used in some 2301A and DRU controls. The suspect IC was obtained by Woodward from an unapproved supplier. The evaluation was concluded on 09/08/09 and was determined to be a reportable defect as defined by 10CFR21.
On 8/14/09, Woodward confirmed that they had shipped ESI a total of thirty-four (34) 2301A and DRU controls with nuclear part numbers that contained an IC (Woodward P/N 1688-767) from a suspect lot. The lot was dated 12/12/08 and was received by Woodward from an unapproved supplier. Eight (8) of the 34 controls were subsequently shipped by ESI to nuclear customers (2 domestic plants and 3 foreign plants) before the issue was identified.
To date, no operability issues have been reported or observed with 2301A and DRU controls containing the suspect IC.
In the DRU, the IC is used in the raise-lower circuit and in the ramp time circuit (the ramp time circuit controls the ramp rate of the DRU). The DRU is primarily used as the speed reference input signal to the 2301A and provides remote speed adjustment for the 2301A (similar to the function of a motor operated potentiometer - MOP).
In some applications, the DRU has also been used as a replacement for the voltage regulator MOP; in this case, the DRU provides the voltage adjustment signal to the voltage regulator.
Failure of this IC could impact speed (frequency) control (and in some cases voltage control) of the EDG.
In the 2301A, the IC is used in the start fuel limit circuit and in the speed signal input (magnetic pickup) circuit. The 2301A is the electronic governor used on many EDG's. It provides speed and/or load control of the diesel engine by communicating with the governor/actuator mounted on the diesel engine. Failure of this IC could impact speed (frequency) control of the EDG.
