TECHNICAL SPECIFICATIONS REQUIRED PLANT SHUTDOWN BEGAN AND THEN TERMINATED
"Unit shutdown was commenced at 2305 to comply with requirements of technical specification 3.0.3. 14 and 15 Containment Fan Coil Units (CFCU'S), 2 of 5 total CFCU's, had been removed from service to remove silt buildup in their emergency supply piping. While in this configuration, a tubing line supplying service water pressure for control of the 13SW223 (outlet flow control valve) for 13 CFCU developed a leak that rendered that valve and associated CFCU inoperable. With 3 CFCU's inoperable entry into technical specification 3.0.3 was required. A turbine load reduction was commenced at 2305 at 1% per hour. The 15 CFCU was restored to operable status at 2320 and the technical specification 3.0.3 and the load reduction were terminated. 14 CFCU was returned to operable at 2323. Repairs were made on the tubing for 13 CFCU and that was returned to operable status at 0009 on 5/6/05. 11 and 12 CFCU's were operable and in service for the duration of the event. The unit has been returned to 100% rated power.
"The only other safety related equipment removed from service at the time of the event was the 13 service water pump for investigation of a reduced flow condition, and had no impact on this event.
The licensee notified the NRC Resident Inspector.

PART 21 NOTIFICATION OF FAILED SURFACE COATINGS ON FANS
Howden Buffalo provided the following information via facsimile:
"In accordance with subject regulation and Howden Buffalo internal procedures, Howden Buffalo is submitting a report of a defect or failure to comply for basic components supplied to a nuclear facility.
"Duke Energy, Oconee Plant, reported insufficient adhesion of Carboline topcoat to Carboline primer, resulting in separation of the topcoat on two fans and one other fan inlet bell. The items were manufactured, painted, and supplied to Duke Oconee during the period February 2002 thru March 2002, as basic components in a nuclear safety related application. The three affected items were part of ten complete fans delivered to Duke Oconee both before and after the affected units.
"Howden Buffalo conducted an initial investigation that included both Duke Power Materials Engineering & Lab Services and Carboline. Our investigation concluded that coating materials were not defective however, application of Carboline primer was not in accordance with Carboline recommendations for sufficient curing of the primer, resulting in accumulation of VOC's from the uncured primer and ultimate separation of the topcoats.
"Howden Buffalo has reviewed internal plant procedures for application of Carboline primer and topcoat, including surface preparation, and found that the procedures failed to incorporate Carboline updated requirements for sufficient curing of the primer. All internal procedures are now revised to incorporate Carboline requirements in their entirety. Howden Buffalo procedures for supplying Carboline coating as a basic component were applicable during the period of October 2001 thru March 2005. Howden Buffalo is contacting each of these customers to a) advise of a potential defect in the Carboline coating, b) recommend inspection criteria, and c) provide contact information.
"Summary evaluation: Review of documentation for this sales order, including all paint surveillance records, does not support a conclusion that this defect is limited only to the fans delivered for this order. Root cause of paint failure would appear to be insufficient training in procedures for surface preparation and preparation and application of primer and paint. Environmental limitations for temperature and relative humidity may not have been correctly considered for drying time requirements. Notification to NRC and to all customers of safety-related coating is required."
Howden Buffalo item number: 540059-080
Reactor building cooling unit fans serial numbers 004, 005, and 006
Nature of defect: Insufficient adhesion of Carboline topcoat to Carboline primer - topcoat flaking from two fans and one fan inlet bell.
Affected safety related orders: Duke (Oconee) shipped 11/2/01
Exelon (Dresden) shipped 3/28/03
Edison Material Supply (SONGS) shipped 7/28/04
Amergen Energy (Oyster Creek) shipped 10/31/02
