Arnie Gundersen, Chief Engineer at Fairewinds Energy Education:
Tokyo Electric has admitted that the boron between these fuel cells — there’s a boron wafer in between the fuel to prevent something called an inadvertent criticality, you can have a nuclear chain reaction in the fuel pool, and that’s not a good thing — but they’ve admitted that all the boron has disintegrated.
So the only thing preventing a chain reaction from occurring […] in the fuel racks themselves, is the fact they put all sorts of boron in the water.
But if the rods get too close to each other, they can still fire up again and create a chain reaction in the nuclear fuel pool.

- Gundersen: 200 brand new fuel bundles in Fukushima Unit 4 pool are most at risk to start nuclear chain reaction — If too close together during removal, there will be a criticality — “They have to be very, very cautious” (AUDIO) September 27, 2013
- Gundersen: Fuel already “very close to going critical” at Unit 4 — Must be extraordinarily careful about starting chain reaction (VIDEO) November 15, 2013
- Gundersen: Unit 4 pool can turn into a nuclear reactor as they pull rods up — Bloomberg: Like a “self-sustained chain reaction similar to meltdowns” — NHK: Fuel is 1% plutonium (VIDEO) November 19, 2013
- Nuclear Engineer: New cover on Unit 4 can trap hydrogen gas during criticality in fuel pool — Blast would be close to a nuclear explosion, from a practical standpoint (AUDIO) November 22, 2013
- Ex-Fukushima Worker: High risk they’ll break fuel rods in Unit 4 pool — Gundersen: Moving fuel risks nuclear chain reaction; You can’t stop it, no control rods to control it August 14, 2013
