The Bucks U2 outage extension is necessary due to delays caused by a pressure
boundary failure on the lower bonnet of the TSV. PG&E is currently evaluating both
temporary and permanent repair options. While the outage may extend beyond one month,
the team hopes to have more clarity in the coming weeks to support an additional
extension request. The extension will also account for the extensive testing required before
the unit can be safely returned to service. This routine maintenance outage will follow the
previously executed procedures that have been coordinated with your office.
If you have questions or comments regarding this matter, please contact Jamie Visinoni,
senior license coordinator for PG&E, at (530) 215-6676.
Sincerely,
Jamie Visinoni
On behalf of
Matthew Joseph
Supervisor, Hydro License Management
