| NRC BULLETIN 91-01, 24 HOUR REPORT -                                         |
|                                                                              |
| At 1335 on 07/17/00, it was discovered that an NCSA mass control was lost in |
| a compressor seal can storage area in the X-330 building. Two seal cans were |
| identified to contain more items than specifically permitted by              |
| NCSA-0330_003.A02 requirement #4 which states:  "Only one seal set shall be  |
| in each seal can."  One seal can was discovered to contain two seal sets and |
| a second seal can was discovered to contain one seal with several (3 or 4)   |
| additional seal parts.  This deficiency was discovered during recovery       |
| activities for NCS event report PTS-00-065 (NRC Event Number #37172)         |
| involving a spacing violation of NCSA-0330_003.A02, requirement #8.          |
|                                                                              |
| This event resulted in the loss of one control (mass) of the double          |
| criticality control principle.  NCS interaction and enrichment control was   |
| maintained throughout this event.                                            |
|                                                                              |
| NCSA-0330_003.A02 requirement #4 compliance was restored at 1415 when the    |
| extra seal and seal parts were stored individually in seal cans under NCS    |
| Engineering guidance.  Complete compliance with NCSA-0330_003.A02 (refer to  |
| NCS event #PTS-00-065) was established at 1705.                              |
|                                                                              |
| SAFETY SIGNIFICANCE OF EVENT:                                                |
|                                                                              |
| The safety significance of this event is low.  NCSE-0330_003.101 analyzes    |
| greater than safe mass in a group of seal cans.  In this analysis it states  |
| that with an enrichment limit of 15% U-235, the amount of uranium in a seal  |
| can would have to be exceeded by 4.6 times the normal amount to reach the    |
| minimum critical mass.  In this event two seal cans were found to be double  |
| loaded.  Assuming that both overloaded seal cans were next to each other,    |
| the mass in the cans is less than the minimum critical mass.  Note: these    |
| cans were found because the group they were in was being moved to correct a  |
| spacing violation between two other seal can groups. The overloaded seal     |
| cans were not directly involved in the spacing violation.                    |
|                                                                              |
| POTENTIAL CRITICALITY PATHWAYS INVOLVED [BRIEF SCENARIO(S) OF HOW            |
| CRITICALITY COULD OCCUR]:                                                    |
|                                                                              |
| For a criticality to occur, the seal cans would have to have more than a     |
| double batch and the enrichment exceed 15% U-235.                            |
|                                                                              |
| CONTROLLED PARAMETERS (MASS, MODERATION, (GEOMETRY, CONCENTRATION, ETC):     |
|                                                                              |
| The controlled parameters in this case are mass, enrichment and              |
| interaction.                                                                 |
|                                                                              |
| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS     |
| LIMIT AND % WORST CASE OF CRITICAL MASS):                                    |
|                                                                              |
| The total amount of uranium in the 47 seal cans involved (including the two  |
| overloaded cans) is estimated to be 1715 grams uranium or 257.3 grams of     |
| U-235.  The maximum enrichment for this NCSA is limited to 15% U-235 and the |
| form of the material is dry UO2F2.                                           |
|                                                                              |
| NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION   |
| OF THE FAILURES OR DEFICIENCIES:                                             |
|                                                                              |
| The NCS mass control was lost in this case.  Only one seal is allowed to be  |
| placed In a seal can.                                                        |
|                                                                              |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS IMPLEMENTED:   |
|                                                                              |
| At 1415, NCSA-0330_ 003.A02 compliance was restored. The extra seal parts    |
| were removed and stored individually in separate seal storage cans.          |
|                                                                              |
| The NRC Resident Inspector and the DOE Site Representative were notified of  |
| this event.                                                                  |

| On 8/2/00 at 0035 hours maintenance personnel performing walkdown            |
| verifications for NRC Event PTS-00-066 discovered a seal can containing      |
| several pieces of seals that were more than volume of one seal.  Compliance  |
| was re-established at 0250hrs under NCS Engineering guidance.  The various   |
| seal parts were separated into three seal cans and properly stored per the   |
| NCSA.  At the time of this Update, a 100% Walkdown of all Seal Cans in       |
| storage is in progress.                                                      |

| INADVERTENT HALON DISCHARGE AT IRRADIATOR FACILITY                           |
|                                                                              |
| The licensee reported that a halon fire suppression system at the Kirkland   |
| AFB irradiator facility discharged without an alarm or manual actuation. The |
| source rack was in the shielded position throughout the event. All other     |
| safety systems, including the fire detection system, remained functional.    |
| The licensee has contacted the fire suppression system vendor to investigate |
| the discharge.                                                               |
|                                                                              |
| The licensee has contacted NRC Region IV (Gaines) regarding this event.      |
