no. 1 reactor is looking in better shape. Three workers trying to help restore the ability to cool the no. 3 reactor internally were exposed to a massive dose of radiation 120-180 millisieverts. They were rushed to the hospital. No.3 reactor, by far in the worst shape structurally, is a continuing problem. No. 4's cooling pool for spent rods is also a continuing problem. They are getting numbers for how cool it is that are very low, so they are assuming the sensor is broken.
