BOARDMAN, Ore. (AP) - The coal-fired electricity plant at Boardman in Eastern Oregon has been offline since July 1 because of a shock in the steam pipes, and it could take another month to get back online.
    
Portland General Electric is getting power from other sources in the meantime.
    
Spokesman Steve Corson says the shock rattled one pipe 36 inches in diameter out of its hangers. It fell several feet.
    
It didn't rupture, and no steam was released. Nobody was hurt.
    
Corson says the initial analysis points to a thermal water hammer, caused by hot steam coming into contact with cooler liquids and gases.
    
The plant has 110 full-time employees. PGE supplies electricity from it for about 250,000 customers. The utility owns 65 percent of the plant.
