| "At approximately 1220 hours on 12/30/00, a process operator was conducting  |
| weekly valve status checks on the cell floor above the extended range        |
| products station when three CADP smoke heads alarmed. The operator did see a |
| visible haze and smell HF as he immediately left the area. 'See and flee'    |
| emergency procedures were immediately implemented. The affected ERP          |
| withdrawal station was in an applicable TSR mode (withdrawal) at the time of |
| the alarm. Results of all surveys performed for airborne HF and radiation    |
| were less than MDA. At 1324 hours an 'all clear' was granted on emergency    |
| response. PORTS is reporting this alarm as a valid actuation of a 'Q' safety |

| "On December 31, 2000, at about 0130 PST, containment normal cooler unit     |
| ME201 tripped on indicated high temperature (cause under investigation).     |
| During preparations to start the opposite train containment normal cooler    |
| Unit (ME202), in response to the expected slow increase in containment       |
| temperature, Operators manually started the 4 containment emergency cooler   |
| units (an engineered safety features system).  At about 0220 PST Operators   |
| started normal cooler unit ME202 and stopped the 4 ECUs.  Consistent with    |
| the guidance provided in NUREG-1022, Rev 1, SCE is reporting this occurrence |
| in accordance with 10CFR50.72(b)(2)(ii) for a manual start of an ESF         |

| Unit 3  was operating at about 85% power; and Unit 1 remains permanently     |
| defueled.  SCE will notify the NRC resident inspectors about this occurrence |
