Fukushima and Beyond ?.

A view based on observations made via internet content !.

 It is now almost thirteen months since the Earthquake, that apparently triggered the Fukushima Emergency !. At the start of this situation, assurances were given, by many, that everything was OK, and that the Reactors had closed down, and posed no appreciable threat !. Since then there has been a number of explosions, but a far as can be seen, none of these explosions have been Nuclear in nature, but have been of a conventional nature, this resulting in a spreading of Nuclear, radioactive materials, beyond the confines of the Nuclear site !.  This appears to have resulted in the Contamination of a wide area, including many pubic places !

 The Contamination appears to be  of a variable type, and includes many Hot-Spots !. While many appear to detect the contamination at various places across the Globe, the Risks posed appear to be somewhat controversial, though the Numbers given appear to suggest a very real threat, to health and life !.

 The Spent Fuel Stores, in which the Spent Fuel Rods are kept immersed in Water, to both cool them and stop them from oxidising, and producing Hydrogen gas !. Appear to be vulnerable to disruption by a further substantial earthquake ! The Spent Fuel Stores at Daiichi Reactors 1, 2, 3, and 4 are apparently all considered vulnerable !.  The condition of these store might make the removal of the Spent Fuel Rods problematic ! While find suitable alternative storage might also be problematic !. But over a year has now past, and this appears to be developing into a Long Emergency !.  The Daiichi, no 4 Reactor was fueled with Mox, Mixed Oxide Fuel, and it is understood that it was undergoing refueling on March 11th 2011 when the incident occurred and that its New Fuel Rods are in it’s Spent Reactor Store !. This in itself may mean that Reactor  4’s Spent Fuel Store poses a Greater risk than the other stores ?. There is also said to be a Common Fuel Pool which is said to be located at ground level, whereas the other Spent Fuel stores are located above the Reactors at the top of the Reactor buildings !.

 The issue of harm is clearly a complex one, and this is made even more complex by the fact that the expert opinion tends to divide into one or two camps !. That is to say For or Against !. At the same time a vast collection of information exists, but much of this requires expert interpretation !.

 At the end of the day Nuclear will not go away !. It will be with us for thousands of years !. So there is a future need to have experts with the knowledge and skills as well as practical experience, to deal with future situations !.

 The Current Culture in relation to Nuclear Technology, appears somewhat wanting !. This appears to be compounded by the fact that Civil Nuclear Power, is to a large extent the child of the Military Industrial Complex, and as such appears to bring with it Millitary Values !. Particularly in relation to risk !
