| AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE |
| |
| "Thursday, 10/11/01 a Krazan and Associates employee, after working late |
| took his portable moisture density gauge to his residence on Floyd Road in |
| Modesto, California. The gauge was reportedly locked and chained to the rear |
| of his pickup truck , but was not covered. The gauge chain was reportedly |
| cut and the gauge was stolen sometime between 9:00 PM and 6:00 AM on October |
| 12, 2001 by unknown persons. The gauge was a Troxler 3440 Serial Number |
| 231711 containing approximately 10 millicuries of cesium 137 and 40 |
| millicuries of americium 241. The RSO indicated he will be placing an ad in |
| the local newspaper offering a reward for the gauge. The RSO indicated that |
| he has counseled his employee for breaking company rules by taking the gauge |
| to his residence which is against company policy and California |
| regulations." |

| AUTOMATIC REACTOR SCRAM DUE TO MAIN STEAM ISOLATION FOR UNKNOWN
CAUSE |
| |
| Unit 2 was operating at 100% power, steady state, when the Main Steam |
| Isolation Valves (MSIVs) fast closed causing a Reactor Protection System |
| (RPS) full scram, all rods fully inserted. The reactor feedwater pumps |
| tripped on Reactor Vessel Water Level 8 due to controlling reactor pressure |
| with Safety Relief Valves. After the feedwater trip, reactor pressure was |
| reduced to 550-650 psig so condensate booster pumps could inject to the |
| Reactor Pressure Vessel (RPV). At 1043 the Reactor Vessel Water Level 2 was |
| reached on the shrink from closure of the Safety Relief Valves. This in |
| turn caused a valid initiation and injection of the High Pressure Core Spray |
| (HPCS) and isolation of various containment isolation valves. |
| |
| Reactor vessel water level and pressure has been stabilized. HPCS has been |
| restored to standby. The plant is stable in Mode 3. The cause of the MSIV |
| isolation is still under investigation and a normal post scram review is |
| underway. |
| |
| The licensee notified the NRC Resident Inspector and will issue a media |
| release. |

| AUTOMATIC REACTOR TRIP DURING PERFORMANCE OF QUARTERLY ROD
OPERABILITY |
| SURVEILLANCE |
| |
| The licensee reported that during a normal quarterly rod operability |
| surveillance an automatic reactor trip occurred, all rods fully inserted. |
| Preliminary investigation indicates that one rod dropped during rod motion |
| causing a negative rate trip to occur. |
| |
| The Emergency Feedwater system actuated, as expected on a reactor trip, and |
| is providing feedwater to the steam generators. Excess heat is being |
| rejected to the main condensers via the steam dumps. No safety or relief |
| valves opened during the transient. |
| |
| The plant is stable in Mode 3 and an investigation into the event is |
| underway. |
| |
| The licensee notified the NRC Resident Inspector and will issue a media |
| release. |

| 24 HOUR REPORT - NRC BULLETIN 91-01 |
| |
| The following is a faxed report of finding in building X-330: |
| |
| During a building walk down, contaminated items in a category II staging |
| area were observed to be closer than the NCSA plant-048 allowed. The PSS |
| entered an anomalous condition. The items were moved to the appropriate |
| spacing requirements. The anomalous condition was exited. |
| |
| SAFETY SIGNIFICANCE OF EVENTS: |
| |
| The safety significance is low, The safe mass quantity is less than half of |
| the minimum critical mass, in a spherical geometry. and with optimum |
| moderation. The NCSE evaluated two items touching, these items were still |
| separated, had little moderation present, and are not spherical. |
| |
| POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW |
| CRITICALITY COULD OCCUR): |
| |
| In order for a criticality to occur more spacing violations, to increase |
| mass would have had to occur and additional moderating material would be |
| required. |
| |
| CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION,
ETC.): |
| |
| Mass and spacing are controlled. |
| |
| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE
PROCESS |
| LIMIT AND % WORST CASE OF CRITICAL MASS): |
| |
| Items involved were less than safe mass and enriched to 10% or less. |
| |
| NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND
DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| |
| The controls were mass and spacing. Spacing was the control violated. |
| |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS
IMPLEMENTED: |
| |
| The items observed inside the spacing requirements were moved to required |
| spacing requirements. |
| |
| The licensee notified the NRC Resident Inspector and the DOE representative. |
