FukuNuke: Unit 4 Non-Radioactive Fuel To Be Removed First

The fuel removal platform probably doesn't work because of the explosion, but unused fuel is essentially not radioactive, at least not enough that it will harm people close by. 

They would need to fix or replace the fueling platform which has enough precision to fish out each fuel assembly and put it into a cask. Then they would need to replace the over head crane which can lower the cask to ground level. Not clear if they are going to build that over-building first

They are also planning to finally take a look at Unit 1, the one that melted down and blew up the day after the earthquake. The water is probably similar to unit 2 which is dry above the downcomer pipe level, and the basement is half-flooded.

TEPCO to remove unused fuel from No. 4 reactor

The operator of the damaged Fukushima Daiichi nuclear plant has decided to remove 2 unused fuel rods from a storage pool at the No. 4 reactor to look for damage.

This is in preparation for the removal of a large number of the 1,535 used and unused fuel rods stored in the pool, which could pose a threat in the event of another earthquake.

TEPCO to check interior of crippled Fukushima No. 1 reactor

TOKYO, May 28, Kyodo

Tokyo Electric Power Co. said Monday it plans to check the interior of the crippled No. 1 reactor at the Fukushima Daiichi nuclear power plant between late August and September by inserting a camera into the primary containment vessel.

Of the Nos. 1 to 3 reactors that suffered meltdowns in last year's nuclear accident, the utility has so far inserted an endoscope into the No. 2 reactor and found the water level was at a lower-than-expected 60 centimeters, a sign that a large part of the water injected into it is leaking from the vessel.

In the upcoming survey, the company known as TEPCO will check the water level inside the No. 1 reactor's primary containment vessel an...Show full text
