Board agrees complete seismic study needed at Diablo power plant

Diablo Canyon needs a full-on seismic study before the power plant's license is renewed, that's according to the San Luis Obispo County Board of Supervisors.

The board voted this morning to send a letter to the Public Utilities Commission, in support of releasing funds to PG&E for a 3D seismic study. PG&E had already requested the cash.

A 3D study would give the Nuclear Regulatory Commission a better look at the risks associated with a nearby off-shore fault-line, the Shoreline Fault, before it renews the plant's license.

Experts describe a 2D study like an old fashioned x-ray, while a 3-d study is more like a CAT-Scan.

"The 3D seismic survey is a fundamental piece in a complete assessment of this fault," said supervisor Bruce Gibson.

The board also voted in favor of sending a letter to the NRC, requesting the renewal process be delayed.
