PART 21 - POSSIBLE WELD ROD CERTIFICATION ISSUES

"On March 3, 2011, an audit of one of Fisher Control's suppliers determined that weld rod certified by an ISO process (instead of ASME) might have been used for weld repair of castings intended for nuclear service. Fisher and the supplier are in the process of reviewing all orders affected by this issue and have yet to find any that used the subject non-confirming material

"Fisher expects to complete this evaluation by August 26, 2011. At this time, if the review determines that a failure to comply condition exits, Fisher will issue notification per the requirements of 10 CFR 21.21(b)."

* * * UPDATE AT 1300 EDT ON 9/7/11 FROM FITZGERALD TO HUFFMAN VIA FACSIMILE * * *

"Fisher Controls is providing this final notification per the requirements of 10CFR21.21(a).

"On August 3, 2011, Fisher provided an interim report concerning an audit of one of Fisher Control's suppliers and the determination that weld rod certified by an ISO process (instead of ASME) might have been used for weld repair of castings intended for nuclear service.

"Fisher and the supplier have completed the process of reviewing all orders affected by this issue and did not find any orders that used the subject non-conforming material.

"Therefore, Fisher will not issue a notification per the requirements of 10CFR21.21(b), because the review determined that a failure to comply condition does not exist."

AUTOMATIC REACTOR TRIP FOLLOWING MAIN TURBINE TRIP FROM 100% POWER

"On Sept 7, 2011, at 0854, DC Cook Unit 1 reactor automatically tripped due to a trip of the main turbine. The cause of the main turbine trip is still under investigation.

"This event is reportable under 10 CFR 50.72(b)(2)(iv)(B), Reactor Protection System (RPS) actuation, as a four (4) hour report, and under 10 CFR 50.72(b)(3)(iv)(A), specified system actuation of the Auxiliary Feedwater System, as an eight (8) hour report.

"The DC Cook Sr. Resident NRC Inspector has been notified.

"The electrical grid is stable and Unit 1 is being supplied by offsite power. All control rods fully inserted. Decay heat is being removed via steam dumps to the main condenser. Preliminary evaluation indicates all plant systems functioned normally following the reactor trip. DC Cook Unit 1 remains stable in Mode 3 while conducting the post trip review."
