<b>First Posted:</b> 3/4/2008<br><br>BERWICK, Pa. (AP) _ Operators have shut down the Unit 1 reactor at PPL  Corp.'s Susquehanna nuclear power plant to begin a planned refueling and  maintenance.

While the reactor is shut down workers will replace about 40 percent of the  uranium fuel and complete a number of equipment maintenance tasks and  upgrades.
Unit 2 at the plant continues to operate at full power.
Unit 1 is expected to be generating electricity again by the middle of April,  before the arrival of summer weather and the increase in electricity use by  consumers.
The Susquehanna plant is located in Luzerne County about seven miles north of  Berwick.
