Some current reports from Japan Times today:
"Radiation Surges Above 4's Fuel Pool," Kanako Takahara, staff writer.
The nuclear safety agency says the rise indicates "the fuel rods have been further damaged and emitting radioactive substances."
TEPCO unsure "whether surge in radiation caused be spent fuel rods or radioactive material leaking from the reactor's pressure vessel."
A robot took a water sample to analyze the radioactive materials. Fresh water was added onto the rods today, water level unknown.

TEPCO plans to move spent fuel rods out of storage pools at reactors 1 through 4 and move them to a "safe location", but when and how not yet decided (pull by crane or build a special structure?). The "tasks are tough because the site is so radioactive and cluttered with debris from last month's hydrogen explosions.

Getting the radiosctive water out of the flooded turbine room into a storage area will take 4-5 days.

NISA said the utility was "rushing to install seven steel sheets around a seawater intake for reactor 2 and silt fences near intakes for reactors 3 and 4 to hinder spread of thousands of tons of radioactive water it dumped into the ocean."
A seawater sample 15 km away from Minamisoma showed 23 times the permissible level of iodine-131.

In spite of these problems, "Prime Minister Naoto Kan said Tuesday that the situation is "improving step by step and that the release of radioactive particles is declining."
