In the old days this was easy. The power plants were melting down but no one knew what was going on inside them; Water was being poured in and cooking off as steam, and every now and then the way they were getting the water in or the way they were powering the pumps would change, or one of the containment buildings would blow up, or whatever. If you‘ve been reading the last few Fukushima Updates, however, you‘ll know that things related to the crippled nuclear power plant have gotten more, not less complicated, which at first is counter-intuitive, but on reflection, expected.
