| "The HPCI System was taken out of service for surveillance testing earlier   |

| instrumentation was found to be reading well beyond the limits of the normal |
| in service band (+10 to -10).  At that time, HPCI was removed from service   |
| (availability) and isolated.  The proper LCO was entered and troubleshooting |
| is underway."                                                                |

| complications.  Deenergized from 1625 until 1643 which places both units one |
