| TECH SPEC REQUIRED SHUTDOWN DUE A LEAK FROM THE FUEL POOL INTO
CONTAINMENT   |
|                                                                              |
| "On August 17, 2001 at approximately 1245 MST, Palo Verde Unit 3 was at      |
| approximately 97 percent power and at normal RCS temperature and pressure,   |
| when operations personnel detected an increase in containment sump level.    |
| Subsequent investigation revealed the quick operating closure device (QOCD)  |
| (EQID #PCE-M01) that isolates the containment from the fuel transfer tube    |
| was leaking by borated water from the fuel transfer canal at approximately 1 |
| gallon per minute. Operations personnel entered TS LCO 3.6.1 Containment,    |
| Required Action A. This action requires the containment be restored to an    |
| operable status within one hour.                                             |
|                                                                              |
| "Since containment integrity was uncertain, and compliance with LCO 3.6 1    |
| Required Action A could not be met within one hour, operations personnel     |
| entered LCO 3.6.1, Required Action 8.1 at 1345 MST. Required Action B.1      |
| requires the unit be placed in Mode 3 in 6 hours, and Required Action 8.2    |
| requires the unit be placed in Mode 5 within 36 hours, Following operations  |
| briefings, shutdown was commenced at approximately 1645 MST. At this time,   |
| Palo Verde Unit 3 is continuing to reduce power in an orderly manner and     |
| anticipates being in Mode 3 (Hot Standby) by approximately 1845 MST.         |
|                                                                              |
| "There were no other component failures, testing or work in progress that    |
| contributed to this event. The QOCD leak is allowing 4400 part per million   |
| borated water into the containment. There has been no release of             |
| radioactivity to the environment and no impact to the health and safety of   |
| the public has occurred or is anticipated. There is no elevated RCS activity |
| and heat removal is via normal steaming to the main turbine condenser. The   |
| electric grid is stable."                                                    |
|                                                                              |
| The licensee informed the NRC Resident Inspector.                            |
|                                                                              |

| * *                                                                          |
|                                                                              |
| "This notification is a retraction to the August 17, 2001, ENS #38220 which  |
| reported a Palo Verde Nuclear Generating Station Unit 3 shutdown required by |
| Technical Specification 3.6.1. In the condition described by this ENS, the   |
| failure, a loss of containment integrity, never existed. Although personnel  |
| conservatively declared containment inoperable, plant engineers have since   |
| determined that containment integrity per Technical Specification 3.6.1 was  |
| maintained. The water leakage into containment via the Quick Operating       |
| Closure Device (QOCD) 0-rings did not constitute or create a potential       |
| accident leakage path out of containment. Therefore, the subsequent plant    |
| shutdown was not required by a Technical Specification action.               |
|                                                                              |
| "The NRC Resident Inspector has been notified."                              |
|                                                                              |

| The following is from a faxed report:                                        |
|                                                                              |
| At approximately 1630 on October 15, 2001 following an automatic shutdown of |
| Dry Conversion Process Line 2, a higher than normal moisture analytical      |
| result was identified on Line 2A powder outlet cooling hopper. Manual        |
| moisture sample results indicated free moisture content in the U02 powder    |
| averaged 1.2% which is above the operational limit of 0.4% but well below    |
| the safety limit of 11 .2%.                                                  |
|                                                                              |
| The associated outlet hatch valve control valve seats were subsequently      |
| determined to be leaking, leading to material with a higher than normal      |
| moisture content in the cooling hopper. The associated active engineered     |
| control (AEC) interlocks functioned as designed, the cooling hoppers were    |
| isolated, and the conversion process was automatically shutdown, thus no     |
| unsafe condition existed.                                                    |
|                                                                              |
| The affected material has been transferred to favorable geometry containers  |
| per procedure.                                                               |
|                                                                              |
| Controls were reestablished within 4 hours by proper function of the         |
| redundant dewpoint probe interlocks and automatic system shutdown. This      |
| event is reported pursuant to NRC Bulletin 91-01 (within 24 hours) due to    |
| loss of one of two independent moderation controls. Line 2 conversion        |
| remains shutdown pending investigation and implementation of corrective      |
| actions.                                                                     |
|                                                                              |

| Low safety significance - actual moisture content averaged 1.2% (12,200 ppm  |
| H20) within the established uniform moderation limit of 11.2% for (112,000   |
| ppm H20) for the cooling hopper.                                             |
