Notes: 

02/18/2010: A roof known for years to leak when it rained allowed rainwater to short out electrical equipment. One reactor automatically shut down. A worn-out protective device that workers had not replaced because of cost-cutting efforts allowed the electrical problem to trigger an automatic shutdown of a second reactor.
