| Title | San Onofre Emergency Operations (Eof) Inaccessible Due to Road Flooding |
| Event Description | The following information was received from the licensee via e-mail:
On January 9, 2005, at about 1945 PST, the access road to the SONGS MESA facilities became flooded after several days of rain. The San Onofre Emergency Operations Facility (EOF) is located at the MESA and because of the flooding, is inaccessible to passenger vehicles. While the EOF itself is operable, in the event of an Emergency at San Onofre, SCE would direct EOF emergency responders to the alternate EOF located in Irvine, California. SCE is reporting this occurrence to the NRC in accordance with 10CFR50.72(b)(3)(xiii). At the time of this occurrence, Unit 2 was operating at about 100% power and Unit 3 was operating at about 65% power. SCE will notify the NRC resident inspectors about this occurrence and will provide them with a copy of this report.
On January 10, 2005 at about 0143 PST, flooding had dissipated sufficiently for one lane to be passable; at 0615 PST, both lanes were passable. In the event of an Emergency at San Onofre, there is no longer a need to redirect emergency responders to the alternate EOF located in Irvine, California. This report is to advise the NRC of this change in EOF access status. Also note that it is continuing to rain at SONGS and this status is subject to change. At the time of this report, Unit 2 was operating at about 85% power and Unit 3 was at about 80% power. SCE has informed the NRC resident inspectors and will provide them with a copy of this report. Notified R4DO (Bywater).
On January 11, 2005, at about 0041 PST, the access road to the SONGS MESA facilities again became flooded after several days of rain (reference NRC Operations Log Number 41320). The San Onofre Emergency Operations Facility (EOF) is located at the MESA and because of the flooding, is inaccessible to passenger vehicles. While the EOF itself is operable, in the event of an Emergency at San Onofre, SCE would direct EOF emergency responders to the alternate EOF located in Irvine California. SCE is reporting this occurrence to the NRC in accordance with 10CFR50.72(b)(3)(xiii). At the time of this occurrence, Unit 2 was operating at about 85% power and Unit 3 was at about 80% power. SCE will notify the NRC resident inspectors about this occurrence and will provide them with a copy of this report. Notified R4DO (Bywater).
On January 11, 2005, at 0125 PST, Southern California Edison (SCE) reported that the access road to the SONGS MESA facilities had again flooded after several days of rain and that the SONGS Emergency Operations Facility (EOF) was inaccessible to passenger vehicles (NRC Operations Log Number 41320). On January 11, 2005 at about 0535 PST, flooding had dissipated sufficiently for the road to be passable. In the event of an Emergency at San Onofre, there is no longer a need to redirect emergency responders to the alternate EOF located in Irvine California. This report is to advise the NRC of this change in EOF access status. At the time of this report, Unit 2 was operating at about 85% power and Unit 3 was at about 81% power. SCE has informed the NRC resident inspectors and will provide them with a copy of this report. Notified R4DO (Russ Bywater). |
