INDICATION OF CRACK FAILURE ON RCS PRESSURE BOUNDARY PENETRATION

"Unit 1 is currently in a refueling outage in Mode 5. During a routine inservice inspection of the reactor vessel, an indication was discovered on the N1B penetration. This is associated with the suction for B Loop of Reactor Recirculation. At 0746 on 3/23/2004, the Control Room was notified that the evaluation was completed and the indication was determined to be unacceptable under the ASME Section XI Code. Based on guidance provided in NUREG-1022, Rev. 2, this material defect in the primary coolant boundary constitutes a seriously degraded condition and is reportable under 10CFR50.72(b)(3)(ii)(A). A final evaluation of the flaw and a repair plan is being developed."

The licensee informed the NRC Resident Inspector.

*****RETRACTED ON 4/29/04 AT1018 FROM HUFFORD TO LAURA*****

"On March 23, 2004, PPL Susquehanna, LLC reported a material defect discovered on the N1B penetration associated with the suction for the B Loop of Reactor Recirculation. The defect was discovered during routine inservice inspection of the reactor vessel. At the time of the report, the indication was believed to exceed the acceptability standards of ASME Section XI, IWB-3640. Accordingly, an ENS call was made pursuant to the reporting requirements of 10CFR50.72(b)(3)(ii)(A). Engineering analysis subsequently determined that the dimensional characteristics of the flaw were within the acceptability requirements of ASME Section Xl. This analysis conclusion provides the basis for retraction of the ENS report of March 23.

"Although hypothetical flaw growth calculations demonstrated that the flaw size would remain within the allowable envelope of ASME Section Xl, IWB-3641-1 over the next operating cycle, and continued operation without repair of the observed flaw was justified, PPL Susquehanna, LLC performed a weld repair of the defect during the recently completed refueling outage."

THE US ARMY REPORTED A MISSING BEAM SPLITTER FOR A M1A1 TANK.

On 03/03/04 the Texas National Guard discovered that one of their M1A1 tanks which was stored in a outside fenced area at their Army training facility in Wylie, Texas was missing a tritium beam splitter from its muzzle reference sensor. A thorough search was made of the entire area with negative results and a wipe of the tank also tested negative. The beam splitter contained a sealed 10 curie tritium source. All of the other tanks stored in the same fenced area with the one having the missing source were inspected and found to be intact.

* * * RETRACTION AT 1030 ON 2/26/04 GIZICKI TO RIPLEY * * *

Following reinspection, it was determined that the tritium beam splitter was not missing from the muzzle reference sensor. The individual who conducted the initial inspection could not see the illumination in the day light. When it was reinspected in a dark area, appropriate illumination was noted. Therefore the source was still in the beam splitter.

Notified NMSS (Psyk), R3DO (Madera) and R4DO (Graves).

OFFSITE NOTIFICATIONS MADE DUE TO AN ETHYLENE GLYCOL SPILL FROM UNDERGROUND PIPING

Environmental state notification was made on 3/23/04 due to an ethylene glycol spill from the underground circulating water (CW) boiler piping. The spill is isolated and contained on site. Clean-up is in progress, and no discharge to the river occurred. Approximately 100 gallons of ethylene glycol has been cleaned up. The CW system is not effected by this spill. There were no injuries as a result of the spill.

The NRC Resident Inspector will be notified.
