Reflections on a fortnight in Fukushima, BBC, March 24, 2011:

[Emphasis Added]

… Perhaps the most tantalising is a report by Kyodo News, Japan’s principal news agency, to the effect that neutron radiation was observed more than a kilometre from reactor buildings 1 and 2.

Neutrons are emitted during a nuclear chain reaction; so given the context, is Kyodo’s report to be taken as indicating that a chain reaction took place after the reactors shut down?

If it is, does that relate to the company’s warning last week that there was a possibility of “re-criticality” in a pool storing fuel rods? …

Read the report here.

  • I see many titles about the unwanted renew of the chain reaction at Fukushima. But I see no one article explaining the reason of such a news. What data are available that allow to make such a concept? Who had analyzed these data? What kind of predictions can be done on the base of such a concept?
    Before such questions are answered, the concept looks religious, not scientific.

  • Misitu

    The neutron is not a religious concept. If detected, neutrons indicate ongoing fission reactions.

    Your comment smells of hope rather than analysis.
