| TEXAS AGREEMENT STATE REPORT ON DISABLED GAUGE FOR OIL CRACKING PLANT |
| |
| "Licensee immediately suspended operations in the affected "reactor" (oil |
| cracking plant) due to loss of measurement caused by loss of level/density |
| measurements from an Ohmart Corporation (OC) Model SH-F2, source holder, |
| containing 1 curie of Cs-137, Serial # 68526, located on the exterior |
| surface of the SAS Sodium reactor, vessel # R-7202. Operators noted a loss |
| of measurement at approximately 7:00 a.m. When investigating the outside of |
| the reactor vessel, on-site personnel noted that the fixed gauge had broken |
| free of its mounting bracket and fallen, face-down, approximately 10 feet to |
| the ground. Plant personnel immediately notified Techstar, a subsidiary of |
| Ohmart/Vega Corporation, for field service. A service technician arrived on |
| scene, surveyed the gauge for radiation leakage, checked for contamination, |
| and checked the functional operation of the gauge. The shutter was closed |
| and locked by service personnel, until damage could be assessed. No damage |
| was sustained by the gauge. The mechanism was fully functional and has been |
| reinstalled on the reactor vessel. A set screw (a 3/4 to 1 inch bolt) had |
| failed on the mounting bracket, due to suspected structural fatigue and |
| vibration over 11 years since the gauge was installed (December 1992). The |
| gauge was reinstalled in a bracket modified to fit on the welded beam |
| (2-inch pipe), that will not allow the gauge to fall if the set screw fails |
| in the future. All other gauges on site were checked by service personnel |
| for security and possible deterioration on mounting hardware. This gauge was |
| unique in this plant due to it's mounting which has now been upgraded to |
| allow for fail-safe operation without loss of function should the bracket |
| fail. Problem has been corrected by the service company. Modification to the |
| mounting bracket and replacement of the set screw has rectified the cause of |
| this incident and returned the reactor to operation." |

| DEGRADED CONDITION DUE TO DEFECT IN REACTOR VESSEL HEAD PENETRATION |
| |
| "On April 30, 2003, at 1420 hours, with St. Lucie Unit 2 in a refueling |
| outage, FPL discovered a defect in reactor vessel head penetration 72. This |
| flaw was found during the ongoing reactor vessel head inspection being |
| performed in accordance with the requirements of NRC Order EA-03-009. The |
| defect is OD surface connected, extends into the nozzle and penetrates into |
| the J-groove weld between the nozzle and reactor vessel head. The defect is |
| described as an axial flaw, 0.28 inches deep X 0.96 inches long, on the |
| downhill side of the penetration. Per the inspection guidance, surface flaws |
| located in the attachment weld area are not acceptable. |
| |
| "There had been no indication of RCS leakage during the previous cycle's |
| operation. This notification is being made in accordance with 10 CFR |
| 50.72(b)(3)(ii)(A)." |

| is the second flaw found during the current ongoing reactor vessel head |
| inspection being performed in accordance with the requirements of NRC Order |
| EA-03-009. The defect is OD surface connected, extends into the nozzle and |
| through the J-groove weld between the nozzle and reactor vessel head. The |
| defect is described as an axial flaw, 0.39 inches deep X 2.98 inches long, |
| on the downhill side of the penetration. Per the inspection guidance, |
| surface flaws located in the attachment weld area are not acceptable. There |

| "During a walkdown of the Unit 3 reactor vessel [RV] head and CRDM [Control |

| evidence of possible through wall leakage was observed on two CRDM |
| penetrations. The locations are nozzle 4 and nozzle 7. Nozzle 7 had been |
