On the Crazy Temperatures in Reactor 2

Blast from the past: Unit 2 was reported as potentially re-heating in February 2012 (link is active but content of article is no longer up):

Fukushima's No. 2 reactor may be reheating. Japan today. Feb. 13, 2012 - 09:15AM JST
[excerpted] "Temperature readings at one of the crippled Fukushima nuclear reactors have risen above Japan’s stringent new safety standard but there was no immediate danger, its operator said Sunday."
I have been assuming that the spiking readings from unit 2 reported recently were simply a function of TEPCO finally achieving access to high-radiation areas in unit 2.

But perhaps some of the missing fuel from unit 2 is in water and is still fissioning?

I must say though that unit 2 never produces as much visible steam on the webcams as unit 1 and 3.
