PPL Corporation said its 1140 MW Unit 2 at the Susquehanna nuclear power station in Pennsylvania came back online and resumed generating electricity for the regional power grid earlier this week, following a shut down on Friday for scheduled equipment testing.

The company said the problem was corrected and the reactor was safely restarted, adding that no nuclear safety issues were identified as a result of the automatic shutdown.

Meanwhile, following Tuesday’s earthquake on the east coast, workers poured out of PPL Corp.'s 22-story headquarters in Allentown, the city's tallest building.

PPL spokesman Dan McCarthy confirmed that there were no indications of any damage, either to power lines or to the Susquehanna nuclear power plant in north-eastern Pennsylvania. PPL declared the lowest alert level at a nuclear power plant and Unit 1 continued to operate at 100 per cent power, while Unit 2 was already offline for routine maintenance.
