| SAFETY INJECTION SYSTEM  ACTUATION AND CAUSE UNDER INVESTIGATION             |

| "At 20:47 on 3/9/03, Unit 2 experienced a Safety Injection while the plant   |

| was stable at NOP(2235 psig)/NOT                                             |

| (567 degrees) in Mode 3.  All systems actuated as designed.  An operator was |

| operating the 'B'  S/G PORV shortly                                          |

| before the event occurred.  All MSIVs were closed for ongoing work on the    |

| main turbine. The Sequence of                                                |

| events report showed all 3 channels of steam pressure spiking low on the 'B' |

| Steam Generator as the cause of the event. Initial look at trends on the     |

| integrated computer system showed [that] steam pressure channels did not     |

| lower to a point to cause the safety injection.  An Event Review Team is     |

| being formed to investigate this event.                                      |

|                                                                              |

| "A Reactor Coolant System PORV opened due to high pressure when the Spray    |

| valves closed due to the Instrument Air isolation (due to phase 'A') with    |

| the Pressurizer Heaters in manual. The Pressurizer heaters were secured and  |

| Reactor coolant System pressure stabilized.  All ESF systems actuated as     |

| designed. The following systems actuated: Auxiliary Feedwater, Safety        |

| Injection, Phase 'A', Control Room Envelope and Fuel Handling Building HVAC  |

| systems, Essential Cooling Water, Component Cooling Water, Emergency Diesel  |

| Generators and ESF sequencers."                                              |

| There was no safety injection since pressure was maintained above 2199 psi   |

| during the transient (Hi Head is 1700 psi).  Heat removal is being performed |

| through S/G PORVs and Unit 2 is currently stable at Mode 3.                  |

|                                                                              |

| During the eleventh refueling outage on Unit 2 (2R11) the reactor coolant    |

| system low temperature overpressure (LTOP) protection was inoperable due to  |

| the individual power operated relief valves (PORV's) control switches being  |

| selected to the "closed" position. LTOP was unable to perform its required   |

| automatic function from 0829 PT on 03/09/03 until the discovery time of 0731 |

| PT on 03/10/03.  This discrepancy was discovered by the operator during the  |

| beginning of shift board walkdown, at which time the PORV selector switches  |

| were returned to "auto" and LTOP protection was enabled.  At no time were    |

| any of the LTOP setpoints challenged.  Residual Heat Removal (RHR) pump      |

| suction relief valves (setpoint is 450 psi) were also available during this  |

| time frame to provide overpressure protection. Reactor Coolant temperature   |

| was 109 degrees F.  LTOP setpoint was for 435 psi.    The LTOP PORV's        |

| control switches were closed during the vacuum degas procedure.   Licensee   |

| is still investigating this event.                                           |

| At 1137 CST on 03/10/03, with the plant at 87% power, the Main Control Room  |

| team received indications that the seals were deflated on both doors of      |

| primary containment airlock JRB-DRA1.  Personnel were exiting containment    |

| through the airlock at this time.  Personnel were dispatched and airlock     |

| integrity was restored at 1208 CST.  The cause of the condition appears to   |

| be related to the mechanical interlock.  This interlock did not function as  |

| required to prevent deflation of the seals on both doors concurrently.  This |

| condition is being evaluated.                                                |

| "This notification is being made pursuant to NRC regulation                  |

| 10CFR50.72(b)(3)(v)(D), any event or condition that at the time of discovery |

| could have prevented the fulfillment of the safety function of structures or |

| systems that are needed to mitigate the consequences of an accident.         |

|                                                                              |

| "On March 10, 2003 at 22:38, it was determined that the secondary            |

| containment was inoperable due to a leak in the Z sump manway gasket. The    |

| plant was in Mode 5, shutdown, performing fuel shuffle when secondary        |

| containment was declared inoperable. LCO 3.6.4.1 was entered. The fuel       |

| shuffle was secured at 22:40 after the completion of the fuel move that was  |

| in progress. No additional Core Alterations or OPDRVs [Operations            |

| Potentially Draining the Reactor Vessel] were in progress. Upon              |

| investigation into the secondary containment operability, it was determined  |

| that a non-Tech Spec surveillance performed on dayshift also rendered        |

| secondary containment inoperable due to additional leakage pathway via the Z |

| sump.  A principal safety function of Secondary Containment is to limit the  |

| ground level release to the environs of airborne radioactive materials       |

| resulting from a fuel handling accident.                                     |

|                                                                              |

| "As a result of the alignment of the Z sump the potential existed that if a  |

| radioactive release were to occur due to a fuel handling accident, part of   |

| the filtered release via Standby Gas Treatment System could be a ground      |

| level release vice a release through the Elevated Release Point. The         |

| surveillance has been completed and the additional leakage paths that were   |

| opened due to the surveillance have been sealed. The leaking manway gasket   |

| was determined to be due to not adequately torquing the gasket bolts. The    |

| bolts have been retorqued. Secondary containment was reestablished, and was  |

| declared OPERABLE at 02:55, 3-11-03.                                         |

|                                                                              |
