| facility's past) is a potential violation of passive design feature one of   |
| NCSA 0705_076.A03 which credits the physical integrity of X-705 system       |

| "SAFETY SIGNIFICANCE OF EVENTS:  The safety significance of this event is    |
| potentially high (at this time) because the exact amount of Uranium bearing  |
| material that could have entered the opening in the block wall is unknown.   |
| Measurements to quantify the material are in progress.  The apparent block   |
| wall construction (as evidenced by visual inspection of wall openings in the |

| unfavorable geometry voids within and between the blocks compromising the    |

| material entered the void spaces of the block wall, 2) the material has      |
| collected in the multiple voids resulting in a single unfavorable geometry   |
| configuration, 3) the material has a high enrichment and uranium             |
| concentration, and 4) the material would become sufficiently moderated, then |
| a potentially critical configuration could result.  Note that no spills or   |
| leaks of uranium bearing material from present X-705 systems has occurred at |
| this time.  The material in question has apparently been there for some      |

| "CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION,
ETC.):    |
| Double contingency for inadvertent containers relies upon the physical       |
| integrity of X-705 piping to prevent a spill of an unsafe amount of          |
| material.  An unsafe amount is defined by the concentration and enrichment   |
| of the material.  Double contingency also relies upon administrative         |
| controls limiting the presence of unfavorable geometry or unsafe volume      |
| containers that could collect a spill or leak."                              |

| ***** UPDATE FROM JIM McCLEERY TO LEIGH TROCINE AT 1942 ON 09/27/01 *****    |
|                                                                              |
| The following text is a portion of a facsimile received from Portsmouth      |
| personnel:                                                                   |
|                                                                              |
| "Update #1 - Conservative NDA analysis of the area near column A-16          |
| indicates a total maximum mass of 225+/-113 grams 235U with an enrichment of |
| 8.2% is present (preliminary NDA analysis reported less conservative         |
| values), which is less than the safe mass limit for uranium.  Investigations |
| to determine the extent of condition have identified three additional areas  |
| of potential concern in X-705 Recovery.  These areas are:  the wall near the |
| A-loop overflow column, the wall adjacent to the Calciner system, and the    |
| wall near the top of the B-38 storage columns.  Each of these areas has      |
| received preliminary scans via NDA analysis to determine the potential for   |
| uranium material holdup in the block walls.  Preliminary results indicate    |
| that the amount of material, if any, in the wall near the A-loop overflow    |
| and near the Calciner are bounded by the amount quantified near column A-6.  |
| More detailed [quantitative] NDA scans for these two locations (to           |
| differentiate between surface contamination, uranium holdup, and background) |
| are currently in progress and will be reported when available.  Preliminary  |
| results indicate that no material is suspect in the wall near the B-38       |
| storage column (near background readings).  Additional NDA scans are         |
| currently in progress to locate any other potential areas of concern in the  |
| Recovery Area.                                                               |

| "SAFETY SIGNIFICANCE OF EVENTS:  The safety significance of this event is    |
| now low because the amount of uranium bearing material that entered the      |
| openings in the block wall is known to be less that 338 grams 235U which is  |
| less than the safe mass limit for uranium."                                  |

| "Update #2 - More detailed quantitative NDA scans for the wall near the      |
| A-loop overflow column indicate a total maximum mass of 92+/-46 grams 235U   |
| with an enrichment of 86% is present (less than a safe mass).  Quantitative  |
| NDA scans for the wall adjacent to the Calciner system indicate a total      |
| maximum mass of 201+/-101 grams 235U with an enrichment of 5.3% (also less   |
| than a safe mass).  It should be noted that these results incorporate        |

| of block wall was removed in accordance with NCSA-0705_135.  Following       |

| subjected to additional NDA analysis.  Conservative NDA analysis indicated   |
| less than 306 grams U235 total spread over the five additional locations.    |
| In a second removal operation, additional blocks were removed at four        |
| locations adjacent to the primary area where greater than 15 grams U235 was  |
| indicated.  When combining all NDA estimates which make conservative         |
| assumptions about the distribution of uranium-bearing material in the wall   |

| POSSIBLE OVEREXPOSURE BASED ON DOSIMETRY READING                             |
|                                                                              |
| On 2/1/2002, the University Radiation Safety Officer received the            |
| 10/15-11/14/2001 TLD results from their dosimetry processor (Landauer),      |
| which  indicated that an individual had received an extremity dose of 72.6   |
| rem to the hand. This result was based on readings from a ring dosimeter.    |
| However, based upon results from another ring dosimeter worn by the          |
| individual during the period (114 mrem) , the individual's  whole body       |
| dosimetery (33 mrem), and the individual's work duties, the RSO believes     |
| that this result may be in error. The RSO has been in contact with NRC       |
| Region III regarding this incident.                                          |

| SMALL QUANTITY OF RADIOACTIVE WASTE MISSING                                  |
|                                                                              |
| The licensee reported that a bag of radioactive waste containing 132         |
| microcuries of I-125 was misplaced between 12/27/01 and 1/10/02. The         |
| licensee believes that the waste may have been inadvertently disposed of as  |
| biohazardous waste. In this case, the material would have been biologically  |
| decontaminated and then sent to a sanitary landfill for disposal. Due to the |
| low penetrating nature of the radioactivity, the licensee does not believe   |
| that a search of the landfill would be of much benefit. A calculation of the |
| possible dose resulting from the handling of this material indicated that an |
| individual would not receive a dose in excess of 1 mrem.                     |
