| DISCOVERY THAT AN AMERICIUM-241 SOURCE WAS MISSING FROM NORTHERN
ENGINEERING |
| IN GALEVILLE, WISCONSIN                                                      |
|                                                                              |
| At approximately 1500 CDT, the licensee discovered that an americium-241     |
| source with an activity of about 11 millicuries was missing from the         |
| Galeville facility.  It had previously been used as a static eliminator.     |
| Apparently, the licensee discontinued use of these static eliminators some   |
| time ago.  Two had been returned to the supplier (NRD), one was found in an  |
| unusual location, and one was unaccounted.                                   |
|                                                                              |
| The licensee stated that the corporate office was located in Sparta,         |
| Wisconsin.                                                                   |
|                                                                              |
| The licensee notified the NRC Region 3 office (Mike Lafranzo).               |
|                                                                              |

| "On 04/16/02, [a Recirculating Cooling Water (RCW)]/FREON status walkdown    |
| was performed to ensure compliance with the Nuclear Criticality Safety (NCS) |
| controls of NCSA-0333_015A06.  During the walkdown, it was found that the    |
| R-114 level on cell 33-6-9 Even and the East 'A' Booster could not be seen   |
| on the [sight] glass.  The RCW supply block valves were found to be open."   |
|                                                                              |
| "NCSA-0333_015.A06 requires that: 'The liquid R-114 level on shutdown cells  |
| shall be monitored weekly unless the R-114 is drained.  If the R-114 level   |
| is not visible on the level indicator for the coolant system, the RCW supply |
| block valve shall be closed.' "                                              |
|                                                                              |
| "Since the R-114 was not visible on the [sight] glasses and the RCW supply   |
| block valves were open, the NCSA control was violated."                      |

| "SAFETY SIGNIFICANCE OF EVENTS:  The safety significant of this event is     |
| low.  The equipment involved contains less than a safe mass of material, and |
| for water to get to material contained in the process side of the equipment, |
| the condenser tubes must leak (filling the coolant system with water up to   |
| the level of the cooler tubes), and the cooler tubes must leak allowing the  |
| water to enter the process side of the equipment.  The pressure of the       |
| coolant system for Cell 33-6-9 Even is approximately 8 psig, and the         |
| pressure of the East 'A' Booster coolant is greater than 30 psig.            |
| Therefore, neither the condenser nor the cooler tubes appear to be           |
| leaking."                                                                    |

| "POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW           |
| CRITICALITY COULD OCCUR):  For a criticality to occur, water must leak       |
| across the coolant system (i.e., both the condenser and cooler heat exchange |
| tubes must be breached) and into the process side of the equipment.  Once on |
| the process side of the equipment, the water has to cause material to        |
| relocate and accumulate such that the resulting mixture contains more than a |
| critical mass."                                                              |

| Even is 1.431 wt. percent 235U, the enrichment on East 'A' Booster is 1.763  |
| wt. percent 235U, and there is no equipment in the X-333 facility that has a |
| greater than safe mass deposit.  The safe mass of uranium at 2 wt. percent   |
