Though Tepco stated they could not measure neutron ray in November, Tepco turned out to have no equipment to know if recriticality is going on by measuring neutron ray.
It became clear by the question of Japanese journalist, Iwakami Yasumi on the press conference of 2/13/2012.

Having reactor 2 heated, it became important to know if there is recriticality going on.
For the question of Mr. Iwakami to ask if they didn’t measure neutron ray, Tepco answered it is impossible to measure neutron ray out of reactor because it’s protected by perfectly designed facility.
However, when they measured Xe133 and 135 on 11/1/2011, Tepco denied the possibility of recriticality to state they couldn’t detect neutron ray in the plant area.
The statement of 2/13/2012 contradicts this explanation.
Japanese government declared cold shutdown without measuring neutron ray.
Their way of measuring Xe135 is suspicious too.
On 2/12/2012, they announced the Xe135 was not detectable (less than 9.5×10-2Bq/cm3)

However, the detectable limit was 1.0×10-5Bq/cm3 when they measured it in November.
They raised the limit by 10,000 times.
(9.5×10-2Bq/cm3 is almost 1.0×10-1Bq/cm3. They might have wanted to write 10-2, instead of 10-1.)
When it fissions, Xe135 is produced 10,000 times much as usual.

Leaks we have no leaks: Amazing: Japan Gone Nuts: NISA Declares No Contaminated Water Leak From Fuku-I, in the Past, Now, and the Future!
http://is.gd/Cu8YWN
snip
The national government under PM Noda is about to become the laughing stock of the world, the Nuclear and Industrial Safety Agency is busy rewriting the definition of “leak”.
Tokyo Shinbun reports that NISA has decided to basically “nullify” the leaks of contaminated water from Fukushima I Nuclear Power Plant in the past, and declare that there will be no leak in the future either, even if there is actually a leak or deliberate discharge. Why? Because NISA says so.
NISA considers the amount of contaminated water into the ocean to be zero
There have been several leaks of water contaminated with radioactive materials from Fukushima I Nuclear Power Plant. Tokyo Shinbun has found out through own investigation that the Nuclear and Industrial Safety Agency under the Ministry of Economy, Trade and Industry has treated the amount of the leaks as “zero” from a legal [or regulatory] point of view, because it was a “state of emergency”. The Agency has said it will treat the future leaks and deliberate discharges into the ocean the same way. The national government is scheduled to declare a “cold shutdown state” on December 16, but we are suspicious of the government’s position that seems to ignore the suppression of the radioactive materials released from the plant, which is one of the important conditions [of the cold shutdown "state"].
TEPCO and the Nuclear Mafia: http://is.gd/b8kXDL

Why does TEPCO and the Japanese Gov’t want to declare it’s Fukushima disaster Stable and more importantly, what do they hope to accomplish by doing it now?
A. If the people “swallow” this Nuclear Baloney (NB) then TEPCO and their other Gov’t Leaders get to keep their jobs and march onward toward a nuclear future while the Nuclear refugees are “encouraged” to return to their Fukushima homes; letting history be the judge of whether or not this was the RIGHT decision.
B. The people of Japan reject the concept of a “cold shut down” in which case TEPCO, in time, gets nationalized and Japan develops a 20 year plan to replace it’s reactors with solar of all flavors!
C. The people of Japan are insulted by what TEPCO and their Gov’t is saying and take to the streets to DEMAND immediate change. TEPCO and their Government overseers are both swept away in order to placate the people of Japan. The Nuclear Refugees get settlements and the area around Fukushima is closed to all but scientific personal for the foreseeable future. Japan’s PM pledges to “race” Germany toward New Japanese developed Solar and being Nuclear within FIVE years…
The Japanese people are now at a cross roads that will define both their future,their children’s future and possibly the future of Nuclear Power on Earth!
What will they now do:
…Bow to TEPCO?
…Accept their Leaders vow to do better?
…Or Demand an end to using Nuclear ASAP?
How can you have cold shut down without a “reactor”?
There are only three piles of radioactive junk in Fukushima and those are no longer reactors!
Example:
If a tank blows up you have a burned out hulk or mass of scrap but you don’t have a tank any more; that ceased to exist when it blew up…
RE: Cold Shutdown:
It is a misuse of the term to describe a reactor after meltdown as ‘in cold shutdown’. As the fuel assembly is destroyed no shutdown is possible. Fuel is melted together and impossible to control directly. Even if pressure and temperature are unalarming momentarily ‘cold shutdown’ implies complete control which is impossible after meltdown.
Why can’t the Nuclear Industry accept that a melted down reactor is not a normal condition for a reactor which is shut down for any number of reasons and is ABLE TO BE STARTED UP AGAIN SAFELY!
This is a perfect example of Nuclear Oriented Bad Science (N☢ BS) being used to provide dis-information to the public and only serves to call into question all those in the Industry that should be speaking out against this Nuclear Baloney (NB), instead of remaining quiet!
