Unit 2 at PPL’s (NYSE: PPL) Susquehanna nuclear power plant in Pennsylvania has returned to operations after a scheduled refueling and maintenance outage.
Workers replaced approximately 40 percent of the uranium fuel, and performed maintenance and ongoing upgrades, including installing more than 200 new turbine blades and replacing a 24-ton pump and motor that circulates water throughout the reactor. The turbine blade replacements addressed cracking issues. Similar modifications were completed on Unit 1 in 2014.
The plant also completed construction of a new facility, as well as testing and integration of enhanced portable backup equipment that is part of the industry’s response to the 2011 accident at Fukushima.
Both units at Susquehanna undergo refueling every 24 months. Unit 1 continued to operate at full power throughout the outage.
