Partial Meltdowns Presumed at Crippled Reactors

TOKYO — Japanese officials struggled on Sunday to contain a widening nuclear crisis in the aftermath of a devastating earthquake and tsunami, saying they presumed that partial meltdowns had occurred at two crippled reactors and that they were bracing for a second explosion, even as they faced serious cooling problems at four more reactors. The emergency appeared to be the worst involving a nuclear plant since the Chernobyl disaster 25 years ago. http://nyti.ms/eWPPFG
