| "On August 24th at approximately 9:00 a.m. at the Medi-Physics facility |
| located at 4877 Mercury Street. |
| |
| "A courier for Medi-Physics brought back some empty ammo containers from the |

| discovered that one of the containers had removable contamination on the top |
| of the container. From our phone conversation it appears that the level of |
| removable contamination was approximately 300,000 DPM/ 100 cm2. The material |
| was identified as Technetium-99. Medi-Physics will be submitting a letter |
| with the details to my attention. The RSO at the hospital was contacted and |
| he completed a survey to check for contamination at their facility. It is |
| not known at this time the results of that survey. The courier's feet and |

| 4 HOUR REPORT - NRC BULLETIN 91-01 |
| |
| On 9/22/01 at 0225 hrs., operations personnel in the X-330 process building |
| discovered that a UO2F2 deposit with "Greater Than Safe Mass" (GSM) was no |
| longer being buffered with dry air or N2, to greater than or equal to 14 |
| psia. The deposit was located at 31-5, cell 6/8 drop. The buffer pressure |
| had been monitored from an adjacent cell 31-5-8. Block valves marked as open |
| on a pin chart, were found to be closed, thus isolating the deposit from the |
| monitoring cell. The GSM deposit pressure was verified to be 5.81 psia with |
| Maintenance and Test Equipment (M&TE). |
| |
| NCSA-0330_004.A06 requirement #8a states in part, "If there is a deposit |
| greater than a safe mass for systems conditions in the equipment, the |
| pressure in the equipment shall monitored each shift and if the pressure is |
| less than 14 psia it shall be adjusted with dry air or N2 to greater than 14 |
| psia within 12 hours." |
| |
| Buffer pressure was increased to greater than 14 psia at 0425 hours. |
| Remaining areas of the plant with similar conditions were checked and |
| verified to be compliant with the 14 psia Buffer pressure requirement. |
| |
| SAFETY SIGNIFICANCE OF EVENTS: |
| MODERATE, in this event the equipment was potentially without a buffer for 5 |
| months which is insufficient time to allow enough water to enter the pipe |
| and moderate the deposit to the level required to support a criticality. |
| |
| POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW |
| CRITICALITY COULD OCCUR): Sufficient moderation must be added to a deposit |
| at > safe mass to potentially create a critical configuration. This is |
| highly dependent on geometry and reflection conditions. |
| |
| CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION, FTC.): |
| In this event, moderation is the only available control, and it was not |
| maintained. Other parameters, like geometry and reflection, are assumed to |
| be optimum. |
| |
| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS |
| LIMIT AND % WORST CASE OF CRITICAL MASS): |
| Worst case 1549 pounds U02F2 +/- 50% (max. 2323 pounds) at 2.26% based on |
| available Non-Destructive analysis Measurements. This mass is above the |
| minimum critical mass (690 pounds U02F2 at optimum conditions) for this |
| enrichment level. |
| |
| NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| Moderation Control was not maintained for up to 5 months, change in system |
| configuration unknowingly isolated the deposit from pressure monitoring |
| point. |
| |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS IMPLEMENTED: |
| 0425 hours required buffer re-established, the valves involved were opened |
| and tagged to remain open, verified remaining 4 like conditions were |
| buffered as required. Investigation in progress. |
| |
| The licensee notified the NRC Resident Inspector and the on-site DOE |
| representative. |

| CONDITION FOR AN UNUSUAL EVENT REPORTED BUT NOT DECLARED. |
| |
| |
| At 1755ET the sensing line to the "B" Centrifugal Charging Pump (CCP) local |
| discharge pressure gage broke. The operator noticed that the Volume Control |
| Tank level was decreasing, Reactor Coolant System Pressurizer level did not |
| change, but the VCT low level alarm was never reached. The leak was from |
| the sensing line for "B" CCP local discharge pressure gage which is located |
| in the Auxiliary Building. The leak rate was determined to be approximately |
| 25 gpm by using the plant computer monitor to determine the rate of change |
| of the Volume Control Tank level. All the water issuing from the sensing |
| line drained into the Auxiliary Building drain system which drained into the |
| radwaste system. No release offsite. |
| |
| The licensee is not in any Limiting Condition of Operation at this time. |
| "B" CCP is fully operable because it's discharge pressure can be read from |
| several locations, "A" CCP is fully operable. All other emergency core |
| cooling systems, emergency diesel generators are fully operable if needed. |
| State and Local officials were notified of this event. |
| |
| The time between 1801 hours and 1834 hours were used to determine the size |
| of the leak from the Volume Control Tank. |
| |
| The NRC Resident Inspector will be notified of this event by the licensee. |
