Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
What I take from this is:

  1.  they don't have anything under control

  2.  pouring water is a palliative

  3.  nobody has a handle on probable outcome

Now that the radiation levels are manageable they should be burying the place in boric acid.

So, in what may be my last act of "advising", I'll advise you to cut the jargon. -- My old PhD advisor, to me, 26/2/11

It might be safer and longer lasting to cover them with pellets of borosilicate glass made with B10. Borosilicates are sometimes used as control rods. If there are leaks it would be more likely to remain and it could always be wet down with water.

Oil Drum: What do we think we know for sure?

  1. The Japanese government have warned of a grave nuclear incident on a number of occasions.

  2. The status of the reactors, fuel pools and dispersion of radioactive materials continues to get worse, not better.

  3. There are perhaps 7 or 8 reactor loads of fuel in play compared with a single load at Chernobyl and 4 or 5 of those are outside of containment in badly damaged spent fuel pools.

  4. This report suggests that daily release of radioactive 131I and 137Cs is running at around 73% and 60% of Chernobyl respectively.

  5. The Chernobyl fire burned for 8 to 10 days whilst Fukushima Dai-ichi has been emitting radioactive material for around 15 days with no end in sight.

  6. There is a 30 km exclusion zone in place and thousands of residents have become refugees with little prospect of returning home in the near future.

I would say this:
The status of the reactors, fuel pools and dispersion of radioactive materials continues to get worse, not better.
we don't "know for sure". In particular, I don't think the status of the reactors (except maybe number 1) or pools is getting worse, but it is true radioactive dispersion continues. The biggest problem seems to be massive amounts of tainted water, now.

I would worry whether, in an effort to limit the problem of how to deal with the radioactive water, they reduced the introduction of new water to the point where the temperatures got up again. Without good instrumentation and with no forced circulation, how do they know whether there are hot spots in the water that are right on the verge of boiling?
