| NON-CONSERVATIVE ANALYSIS FOR OPRM SCRAM SETPOINTS |
| |
| On July 5, 2001, Detroit Edison received confirmation from General Electric |
| of a non-conservative analysis that supports Operation Power Range Monitor |
| (OPRM) scram setpoints. The non-conservative analysis is generic and been |
| determined to affect Fermi 2. The OPRM had been conservatively declared |
| inoperable on June 27, 2001, at 1333 hours as a result of preliminary |
| notification by General Electric. |
| |
| The consequences of the non-conservative analysis are that the associated |
| OPRM Reactor Protective System (RPS) scram setpoints are non-conservative. |
| The non-conservative RPS setpoints may result in violating the Minimum |
| Critical Power Ratio (MCPR) safety limit during a thermal-hydraulic |
| instability. |
| |
| All OPRM channels have been declared inoperable. Technical Specification |
| 3.3.1.1 Action J requires an alternate method of detecting and suppressing |
| thermal-hydraulic instabilities to be implemented within 12 hours. |
| Alternate methods have been established, thus, the Technical Specification |
| required action is satisfied. Fermi 2 has 120 days to restore the OPRMs to |
| an operable condition. |
| |
| This initial report is being made in accordance with 10CFR50.72 (B)(3)(V)(A) |
| as a condition that could have prevented the fulfillment of the safety |
| function of a system needed to shutdown the reactor. |
| |
| See EN #38104, GE Nuclear Energy 10CFR21 report. |
| |
| The NRC Resident Inspector will be notified. |
| |
| * * * RETRACTED AT 1443 EDT ON 8/17/2001 BY PATRICK FALLON TO FANGIE JONES * |
| * * |
| |
| The licensee is retracting the event notification. |
| |
| "Subsequent design calculations have concluded that there was sufficient |
| conservatism in the existing OPRM RPS scram setpoints to accommodate |
| corrections for the non-conservative analysis performed by General Electric, |
| which was the subject of their 10 CFR 21 Notification dated June 29, 2001 |
| (SC01 -01), and still provide protection for the Minimum Critical Power |
| Ratio (MCPR) Safety Limit during a thermal-hydraulic instability throughout |
| the current operating cycle. The OPRM RPS scram function was not required to |
| be operable prior to the current operating cycle. Since the existing OPRM |
| RPS scram setpoints have been shown to be set conservatively, the OPRM |
| system was operable, and therefore no situation existed which was |
| reportable." |
| |
| The licensee has notified the NRC Resident Inspector. The R3DO (Thomas |
| Kozak) has been notified. |

| LOSS OF EMERGENCY SIREN REMOTE ACTUATION CAPABILITY |
| |
| "Omni phone system was lost resulting in a loss of Emergency Siren remote |
| actuation control. Power was lost 8/16/01 22:25 EDT and restored 8/16/01 |
| 23:55 EDT. Per reportability manual ID# E-02 and Event# SAF 1.10, loss of |
| assessment capability is reportable after 8 hours, but loss of greater than |
| 25% of the sirens for more than one hour constitutes immediate |
| notification. |
| |
| "The omni phone system was lost due to the associated battery voltage |
| becoming too low to support system operation. This was caused by a |
| temporary battery charger installed in place of the normal charger (due to a |
| failed transformer) not maintaining the battery adequately charged. |
| Immediate omni system recovery was effected using available AC power from an |
| alternate source to power up the equipment. Long term plans are to replace |
| the failed transformer and return the normal charger to service." |
| |
| The licensee informed the NRC resident inspector and will inform state/local |
| agencies. |

| TROXLER GAUGE DAMAGED BY VEHICLE AT CONSTRUCTION SITE |
| |
| At 0030EDT on 8/17/01 a light pickup truck struck a Troxler gauge at a road |
| construction project on State Road 340 in Lancaster, PA. The East Lampeter |
| Police Department responded (Incident # 01-414) briefly closing traffic. |
| The RSO surveyed the device and confirmed that the sealed source was intact |
| prior to removal. The Troxler is a model 4640B containing an 8-millicurie |
| Cs-137 source. The licensee is returning the device to the manufacturer's |
| service center in Timonium, MD for inspection and repair. |

| 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 LOC 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 LCD 3.6 1 |
| Required Action A could not be met within one hour, operations personnel |
| entered LCD 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. |
