I would have to think the biggest issue there is keeping the nuclear fuel from exploding due to heat/pressure increases. The update at about 12 noon said that the temperature of the fuel was 50% higher than normal.

The US Air Force was also taking additional coolant supplies to them, to try and combat the fire/ reactor.
