| At 1245 hours on 09/19/01, both the "A" and "B" High Level Condensate probes |
| activated on Autoclave # 3 in the X-334 uranium hexafluoride Sampling        |
| Facility causing a High Condensate Alarm.  The activation of either of these |
| probes will cause the autoclave steam supply valves ("Q" components) to      |
| actuate (close).  The steam supply valves closed, as designed, autoclave # 3 |
| was in TSR Mode 2 (Heating) at the time of the alarm activation.  Operations |
| personnel immediately responded to the alarm in accordance with the approved |
| Alarm Response Procedures.  The alarm reset when operations personnel        |
| drained excess condensate from autoclave drain line, and then acknowledged   |
| the alarm at the local autoclave control panel.  All autoclave (and          |
| cylinder) operating parameters were determined to be within normal ranges.   |
| Autoclave # 3 was placed in TSR mode 7 (Shutdown) by operations personnel    |
| and declared inoperable by the Plant Shift Superintendent.  Based on the     |
| actuation of both High Level Condensate probes, this event is being reported |
| as a valid safety system actuation, a 24-hour NRC event.  An Engineering     |
| Evaluation has been requested to investigate the circumstances surrounding   |
| this safety system actuation.                                                |

| During a meeting to discuss compensatory actions for PR-PTS-01-04202,        |
| additional concerns were raised regarding compliance with the requirements   |
| of NCSA-705-076. Specifically, exterior walls have openings (windows and     |
| gaps) which could allow uranium bearing solution to spray outside the        |
| facility and collect in an unfavorable geometry inadvertent container.  A    |
| walk down was performed.  The findings resulted in a violation of control #  |
| 3 of NCSA 705-76, inadvertent containers.  Compliance with NCSA was          |
| reestablished with the closure of windows, caulking of identified openings   |
| and continued shutdown of system involved.                                   |

| SAFETY SIGNIFICANCE OF EVENTS:                                               |
|                                                                              |
| The safety significance is low because there was no leak of uranium bearing  |
| material! near the identified openings in the walls of the X-705. The two    |
| areas in question are designated as "Inadvertent Container Area" due to the  |
| presence of the Recovery System and Microfiltration, neither of which are    |
| currently in operation due to a stand down of all X-705 operations. The      |
| presence of an inadvertent container in the area is a violation of NCS       |
| controls and one leg of the double contingency principle as described in     |
| NCSE-0705 _076.E.03.                                                         |
|                                                                              |
| POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW            |
| CRITICALITY COULD OCCUR):                                                    |
|                                                                              |
| For a criticality to occur, the following events would be required: The      |
| recovery system or Microfiltration would have to be operating and processing |
| uranium bearing liquid with a high concentration of uranium. Then a leak in  |
| this system must occur such that an unsafe amount of liquid sprays from the  |
| system directly through an open window or through another penetration in the |
| building wall. The liquid would then have to flow or drip into a potentially |
| unfavorable geometry that may be present immediately adjacent to the outside |
| building wall.  Depending on the volume collected, some reflection would     |
| also be required to sustain a critical chain reaction The Recovery and       |
| Microfiltration systems are not currently in operation.                      |
|                                                                              |
| CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION. ETC.):     |
|                                                                              |
| Inadvertent containers are controlled based upon volume (2.5 liters maximum) |
| or geometry (1.5 inches in depth or 4 inches in diameter). The exact         |
| potential collection volume for this event is unknown.  Although analyzed    |
| for 100% enriched materials, the Recovery System would Currently process     |
| materiel with less than or equal to 5% enrichment                            |
|                                                                              |
| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS     |
| LIMIT AND % WORST CASE OF CRITICAL MASS):                                    |
|                                                                              |
| No uranium bearing material was involved in this event. There were no leaks  |
| of uranium bearing materiel in the area during this event. The event         |
| involves the presence of an unsafe geometry (via an opening in the building  |
| block wall) that could collect solution in the event of a spill.             |
|                                                                              |

| OF THE FAILURES OR DEFICIENCIES:                                             |
|                                                                              |
| The presence of holes in the exterior building walls could lead to the       |
| collection of a spill or leak in the unfavorable geometry space. This is a   |
| violation of control #3 of NCSA-0705_076, Inadvertent Containers, which      |
| specifically evaluates this event.  Compliance with inadvertent container    |
| controls was reestablished for a shutdown Recovery system and for the        |
| Microfiltration system (running or shutdown) within four hours of            |
| discovery.                                                                   |
|                                                                              |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS IMPLEMENTED:   |
|                                                                              |
| Compliance with the NCSA was reestablished with the closure of windows,      |
| caulking of identified openings and continued shutdown of Systems involved.  |

| BORIC RESIDUE BUILDUP                                                        |

| Visual inspection of the Unit 2 Steam Generator 2B (SG 2B) lower head bowl   |
| drain during the current refueling outage indicated boron residue buildup on |
| the 0.5" piping immediately below the SG.  The total volume of residue was   |
| approximately 1 cubic inch.  The origin appears to be the partial            |
| penetration of a weld between the reducing coupling and the lower head       |
| shell.  Exact location could not be conclusively determined at this time and |
| additional inspection using NDE will be conducted.  Visual inspection of the |
| other three SG's was also conducted and no indications of leakage were       |
| identified.  State and Local officials will be given a courtesy call.        |
