If The Fuel Pool in reactor #4 Falls or dries up there will no longer be a "northern Hemisphere" to live in !!!!! 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 — Consultants: World’s most serious radiological disaster by far is possible The operation, beginning this November at the plant’s Reactor No. 4, is fraught with danger, including the possibility of a large release of radiation if a fuel assembly breaks, gets stuck or gets too close to an adjacent bundle, said [Arnie Gundersen, a veteran U.S. nuclear engineer and director of Fairewinds Energy Education, who used to build fuel assemblies] and other nuclear experts. Independent consultants Mycle Schneider and Antony Froggatt said recently in their World Nuclear Industry Status Report 2013: “Full release from the Unit-4 spent fuel pool, without any containment or control, could cause by far the most serious radiological disaster to date.” “There is a risk of an inadvertent criticality if the bundles are distorted and get too close to each other,” Gundersen said. He was referring to an atomic chain reaction. “The problem with a fuel pool criticality is that you can’t stop it. There are no control rods to control it,” Gundersen said. “Previously it was a computer-controlled process...It has to be done manually so there is a high risk that they will drop and break one of the fuel rods,” [Toshio Kimura, a former Tepco technician, who worked at Fukushima Daiichi for 11 years] said. enenews/ex-fukushima-worker-high-risk-they-will-break-fuel-rods-in-unit-4-pool-gundersen-nuclear-chain-reaction-risk-if-assemblies-break-you-cant-stop-it-no-control-rods-to-control-it-consulta
