(Newser) – The situation at Japan's stricken Fukushima Dai-ichi nuclear complex may be even more dire than realized, according to American nuclear experts. Authorities at the Nuclear Regulatory Commission suspect that a crack or hole has developed in the floor or wall of a spent fuel pool at the complex, which will thwart efforts to refill the pool with water and prevent dangerous levels of radiation from escaping. The Los Angeles Times explains that unlike the reactor itself, the reactor pool does not have a containment vessel, meaning radioactive gases and particles can more easily escape into the environment if the pool's 130 tons of uranium fuel start to burn.

The assessment is based on information provided by US contractors who were inside the plant at the time of last week's earthquake. If the No. 4 reactor pool is cracked, engineers will face a problem that has no precedent and no obvious solution, according to a physicist with the Union of Concerned Scientists. "My intuition is that this is a terrible situation and it is only going to get worse," he said.

Somebody might ask Uncle Sam where the million gallons of highly radioactive Plutonium water went from the Hanford Washington production reactors. Oh, into the ground water and Columbia River. Oh my!

Couldn't they use barium salts or throw some control rods in there? I'm not a nuclear physicist, but I did stay in a Holiday Inn last night...

Dump cement on it. They probably should have been pumping cement into the reactors instead of sea water to begin with.
