Nov 9 (Reuters) - PPL Corp said it shut down its
1,190-megawatt Unit 2 at the Susquehanna nuclear power plant in
Pennsylvania on Friday after a computer system that controls the
reactor's water level malfunctioned.
    "Operators manually shut down the reactor when they
identified the malfunction," PPL said in a statement.
    During the outage, employees will address the control system
malfunction and begin a previously scheduled turbine blade
inspection, PPL said.
    Susquehanna 1 continued to operate.

So the fact that the regulator and the utility agree that we are safe means little. The regulator is captured by the nuclear utility, which was exactly what lead to the Fukushima disaster. http://funologist.org/2012/10/20/nrc-hides-information-about-high-probability-dam-breaks/
