so basically,
they can't lower the rods completely into the uranium bundle due to some malfunction, and so its still continuously reacting despite the lack of adequate cooling from the coolants. This is causing a lot of heat to build up and pressure to increase, hence prompting threats of a nuclear meltdown
right?
what are the contingency plans to deal with this?
Yes... That's what it seems is happening atm.
Contingency seems to be to evacuate people past a 10km radius from the reactor, They have USAF assets helping in bringing coolant into the facility for the reactors, and were trying to open up valves to relieve pressure, but this last one was suspended when radiation was found at one of the valves.
Also, in regards to what Calister said earlier:

im surprised they havent lowered the control rods 100%, even with an open core that should keep it under control as long as there is water flowing onto it. (unless they already have and somethign is going horribly wrong.
This is from a Nuclear Expert on this article.
"The Japanese reactors are designed to drop neutron-blocking control rods into the core as soon as the plants detect a seismic disturbance. These controls apparently functioned normally. But even after the procedure, scientists say a base level of heat continues to flow, and coolant is needed to constrain those temperatures."
So the problem here is that since Coolant stopped flowing into the reactors even AFTER the control rods were dumped, the continuous flow of heat and no coolant to quench it means we get a meltdown if no means to resolve the issue of cooling the reactor are found.
