Follow-up to: (July 18, 2012) Sources: Unit 4 fuel assembly to be 'cleaned', not yet in shared pool -- Tepco declines to comment -- Trying to determine how much cladding has been eroded or damaged by seawater (NEW PHOTO)
(Subscription Only) Title: TEPCO starts checking unused fuel removed from Fukushima No. 4 unit
Source: Kyodo
Date: Aug. 27
Tokyo Electric Power Co. on Monday started checking the conditions of two unused nuclear fuel assemblies that were taken out from the badly damaged No. 4 reactor unit of its Fukushima Daiichi power plant in July, government officials involved in the issue said.
Studying whether the fuel assemblies have not become corroded or damaged after the devastating accident last year is expected to help the utility predict the conditions of the other assemblies stored inside the spent fuel pools of the crippled four units at the plant. The inspection work is scheduled through Wednesday.
On Monday, workers visually examined one of the two fuel assemblies after taking off its cover and washing it. They have not found major deformation or damage so far.

Needs to be checked and reported on by an unbiased source. As does everything regarding that nuclear plant disaster.

Comment from the follow up link. I believe it is worth posting here. http://enenews.com/sources-unit-4-fuel-assembly-to-be-cleaned-not-yet-in-pool-tepco-declines-to-comment-trying-to-determine-how-much-cladding-has-been-eroded-or-damaged-by-seawater-new-photo

Cleanse it..cleanse it how? with steam?
"One disadvantage of metallic zirconium is that in the case of a loss of coolant accidents (LOCA) in a nuclear reactor, the Zr cladding rapidly reacts with water steam at high temperature. Oxidation of zirconium by water is accompanied by release of hydrogen gas. This oxidation is accelerated at high temperatures, e.g. inside a reactor core if the fuel assemblies are no longer completely covered by liquid water and insufficiently cooled"

they have those wonder rags that they used to clean the first 4 to come out. I wonder why I haven't yet seen them "as advertised on late night TV" yet, perhaps they are stockpiling for unit 4's 1600 assemblies, and the other units, and the common fuel pool's 8000 and all of Japan and the Pacific ocean. wonder rags, gotta make ya'.

Reminder: Fuel assemblies that were removed from SFP4 were NEW, COOL, and UNUSED fuel assemblies. These were not the spent fuel assemblies that burned in the fires after 311. They will tell TEPCO little about the hot spent fuel assemblies in SFP4 that were damaged in the fires in SFP4, other than how the zirconium cladding has been corroded by sea water during the disaster.

Phillip-right on the mark as you usually are. Lets see 2 cool bundles moved in 5 weeks,divided by 1500 equals around 75 years to empty the pool. Cool, except it is balanced 100 feet in the air on a crumbling building.

good point.
It is EASY to remove new fuel assemblies from a spent fuel pool.
But that means NOTHING when it comes to the USED fuel assemblies that are HOT< HOT HOT and probably no longer in existence because they melted, burned and/or are laying on the bottom of the fuel pool in a big flat pancake.

(drum beat) Plutonium comes in your mouth, and lies come in at the eye. I read the latest TEPCO release and I roll my eyes and I sigh. Roll my eyes and I sigh. (snap your fingers) Plutonium comes in your mouth….
