Message from Outage Director On 4/15/04 an Auxiliary Operator making rounds in the Unit I Turbine Building was checking the 1 HX-27 Bus Duct Cooler line up. During the Inspection it was hoted that the associated drain valves had caps installed. The Danger Tag hanging on these components specified that they were to be Uncapped and Open." This condition was In violation of the Danger Tag. The Work Control Center was Immediately notified and corrective action was taken remove the caps. A CAP was written to document the as-found condition' and the corrective action that was taken. The system had been previously drained and released for work and no safety hazard existed. To verify the extent of condition a walk down of all tagged vents and drains in the Turbine Building was conducted looking-for any other problems. No further problems were identified. The placement of the caps on the vent/drain connection Is being investigated as part of the corrective action process.
Use this as operating experience in future pre-job briefs when dealing with vents/drains/caps to stress the Importance of not changing the position of Danger Tagged equipment No OSHA Recordable Injuries.
ALAR l Last 24 Hours Outage to ALARA ll 3.752 R I Dose as of the end of Day 11.

_________________________continuous operation Post Outage BUDGET PERFORMANCE Wihi -2% to 0% Of Challenged I outage budget Safety Snippet Ashes to ashes, dust to dust; A clean workplace Is a must At Pi a couple of years ago during a refueling outage on Unit 1, welding sparks ignited a small fire in some rags in containment. An alert fire watch was able to put out the fire imniediately but the fire was preventable with some very basic housekeeping practices.
Human Performance CONTACT INFORMATION Externial Confirmation: CAP 51472, Unexpected Rise in 'C1 Control Room Emergency - x291 I HUT during OPS Work plan Performance EMT Pager 6442 An Operator failed to verify parameters under his Work Control Center - x6703 responsibility (tank level monitoring) while performing aOC
-x710-pto system alignment operation. Level rose from 26% to 46%.0C
-x710-OtoI Proper verification would have prevented this event.
Lessons Learned - x71 90 - Option 2 Plant Status - x7190 - Option 3 Operating Experience OE1 7973 - Configuration Control Event On 216162004 I&C Technicians were doing Preventive Maintenance on the 2A Feedwater Tempering Flowloop when they inadvertently disconnected the output air line from the 2C Flowloop. This resulted in an unplanned reactivity event when Unit 2 reactor power increased 0.1 %. The apparent cause of the event was a failure to use concurrent verification, flagging, and STAR. With one unit operating and one unit shut down, verification of the correct component Is paramount!
