| MANUAL REACTOR TRIP DUE TO LOSS OF CIRCULATING WATER PUMPS                   |
|                                                                              |
| The licensee reported that Salem Unit 1 manually tripped the reactor due to  |
| a loss of circulating water pumps, caused by a fault on the #2 station power |
| transformer.  The fault isolation caused loss of one of the required two     |
| off-site power sources to both Salem units.  Auxiliary feedwater started on  |
| low steam generator level after isolation of main feedwater due to the       |
| reactor trip.  All system functioned as required.  The unit is stable in Hot |
| Standby and an investigation into the cause of the electrical disturbance is |
| underway.                                                                    |
|                                                                              |
| Two of four reactor coolant pumps tripped when the unit was tripped, which   |
| is expected with the partial loss of off-site power.  Presently, the only    |
| major secondary equipment that is unavailable is associated with the loss of |
| power to two of four non-vital 4 Kv buses.  There is one shutdown Technical  |
| Specification in effect and that is associated with having only one off-site |
| power source.                                                                |

| At 0930 uranium bearing material was observed in the interior spaces of a    |
| block wall in the X-705 recovery area the openings leading to the interior   |
| spaces of the block wall is a violation of administrative control #3 of NCSA |
| 0705_076.A03 because the exact geometry or volume of the potential           |
| collection area is unknown. This is a loss of one leg of double contingency  |
| as defined in NCSE 0705_076.E03. The presence of an unknown (at this time)   |
| amount of Uranium bearing material that was spilled (at some time in the     |
| 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       |
| piping this would represent a loss of the second leg as defined in NCSE      |
| 0705_076.E03                                                                 |

| 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 other areas of Recovery)        |
| indicates the potential for the presence of unfavorable geometry voids       |
| within and between the blocks compromising the exterior building wall.       |
|                                                                              |

| If 1) a significant amount of uranium bearing 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  |

| 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.                                          |

| The openings leading to the interior spaces of the block wall is a violation |
| of administrative control #3 of NCSA.705_076.A03 because the exact geometry  |
| or volume of the potential collection area is unknown. This is a loss of one |
| leg of double contingency as defined in NCSE-0705_076.E03. The presence of   |
| an unknown (at this time) amount of uranium bearing material that has        |
| spilled (at some time in the facility's past) is a potential violation of    |
| passive design feature 1 of NCSA-0705_076.A03 which credits the physical     |
| integrity of  X-705 system piping. This would represent a loss of the second |
