| Title | Emergency Operations Facility Inaccessible Due to Road Flooding |
| Event Description | On January 18, 2010, at about 1950 PST, the access road to the SONGS MESA facilities became flooded after a day 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 [Southern California Edison] 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 shutdown for a Steam Generator Replacement outage and Unit 3 was operating at about 100% power. SCE will notify the NRC Resident Inspectors about this occurrence and will provide them with a copy of this report.
On January 18, 2010 at about 2101 PST, the MESA road flooding had dissipated sufficiently for car traffic 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. Also note that it is expected that rain will continue in the SONGS area during the week of January 17, 2010 and this status is subject to change. At the time of this occurrence, Unit 2 was shutdown for a Steam Generator Replacement Outage and Unit 3 was operating at about 100% power. SCE will notify the NRC Resident Inspectors about this occurrence and will provide them with a copy of this report. Notified R4DO (Werner) and NSIR (Kahler).
On January 20, 2009, at about 2107 PST, the access road to the SONGS MESA facilities again became flooded after a day of rain (reference NRC Operations Log Number 45634). 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 in a Steam Generator Replacement Outage and Unit 3 was operating at about 100% power. SCE will notify the NRC resident inspectors about this occurrence and will provide them with a copy of this report." Notified R4DO (Werner) and NSIR/EP. |
