Update: Emergency outage at South Texas nuke enters second week‏

On November 29, the Unit 2 reactor at the South Texas Project experienced an automatic reactor trip from 100 per cent power. The reactor had just returned to full power after a refueling outage. In the shutdown, a steam dump valve failed to open, and the unit developed a hydrogen leak, according to the NRC’s Prelimary Notification.

It’s now been more than a week since the reactor shut itself down. Other than the Event Report and the Preliminary Notification, there has been no word on when or if the reactor will be repaired and restarted. The Preliminary Notification said that the licensee was issuing a press release, but I can’t find any indication that this was actually done.

The South Texas Project has an application pending to build two more reactors at the Matagorda County site, and has applied for federal loan guarantees for the new units.
