| MISSING M43A1 CHEMICAL AGENT DETECTOR |
| |
| The licensee reported that one M43A1 chemical agent detector, containing 250 |
| �Ci of Am-241, had been lost during a field training exercise at Fort |
| Campbell, KY. A field artillery unit had deployed the detector in accordance |
| with the field manual, but was later unable to locate the detector. Another |
| unit may have taken the detector. |

| NRC BULLETIN 91-01, 24 HOUR REPORT |
| |
| The following is taken from the report faxed to the NRC concerning a |
| degradation of criticality controls: |
| |
| EVENT DESCRIPTION |
| |
| At approximately 1700 on 07/25/2000, six cans without moisture ok tags |
| were discovered on the Erbia can conveyer storage system. Under guidance of |
| the criticality safety engineer, the cans were moved and staged with proper |
| spacing. The cans were than sampled and laboratory results confirmed that |
| each can contained less than the 1.0 wt.% water limit for the conveyer |
| storage. Thus, no unsafe condition existed. |
| |
| SAFETY SIGNIFICANCE OF EVENT: Medium significance, because most of the scrap |
| generated in cans is unmoderated and confirmatory samples verified that the |
| contents of each can were less than 1.0 wt.% water. |
| |
| SAFETY EQUIPMENT STATUS: N/A |
| |
| STATUS OF CORRECTIVE ACTIONS: The cans were moved and staged with |
| appropriate spacing. |
| |
| POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO(S) OF HOW |
| CRITICALITY COULD OCCUR): |
| |
| Calculations demonstrate that a single row of cans will remain subcritical. |
| Therefore, in order for a criticality to occur, the cans would have to |
| contain moderated contents and additional cans would have to have been |
| misplaced before a criticality would have been possible. |
| |
| CONTROLLED PARAMETERS: |
| |
| Moderation is the primary controlled parameter. Each can stored on conveyer |
| storage racks is required to contain less than 1.0 wt.% water. |
| |
| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSE MATERIAL: |
| |
| The six cans contained approximately a total of 106.4 kg of U02 powder and |
| scrap. The maximum enrichment was 4.95% U-235. The cans also contained |
| erbium neutron absorber. |
| |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS IMPLEMENTED: |
| |
| The cans are stored with proper spacing and meetings are planned for each |
| shift to discuss the event and reemphasize criticality safety practices. |
| |
| Notification of this report was made to NRC Inspector (Frank Gee) who was |
| onsite at the time conducting inspection of the criticality controls. |

| REACTOR TRIP DUE TO STEAM GENERATOR LOW LEVEL |
| |
| The '2C' steam generator feedwater regulating valve failed closed for an |
| unknown reason, this led to low level in the steam generator causing a |
| reactor trip. The plant's system responded as designed and all control rods |
| fully inserted. The steam generator power operated relief valves opened |
| momentarily then fully shut. The plant is presently stable in Hot Standby |
| with feed from the auxiliary feedwater pumps and heat removal via the steam |
| dumps to the main condenser. An investigation is in progress to determine |
| the cause of the main feedwater regulating valve closure. |
| |
| The licensee notified the NRC Resident Inspector. |
