>> The LOUC is the same as the bogeyman behind the tree, the >> glowing >> green frogs, etc. LOUC is proportional to the Hubris >> Factor. This can be true, and too often is. But using it as an excuse to ignore LOUC in all cases, or in cases where it suits one desires to do so, helps guarantee UC. Murphy loves this approach. LOUC needs to be part, alas, of any study of a project of any magnitude. A good question (or two) is/are "What is the worst possible outcome, and am I prepared to accept the possibility of that outcome occurring". The first question is often not able to be answered with accuracy but a skim over the release-candidate answers usually gives you a good clue to the second answer. eg As much for the stupidity that even engineers can manage as for the sermon: The Clutha hydro dam is NZ's largest. To stand by the hydraulic jump at the bottom of its spillway when the lake is full is to look into the face of death at a few metres remove. Similar to standing in the hillside caverns at Lauterbrunnen where the Eiger melt water travels its subterranean path. An awe and fear inspiring experience in both cases. But not my point :-). The dam was built on top of an active faultline. Once the implications of this were reanalysed during the decade or so of construction they spent a vast amount of money not only strengthening the design but in modifying the hill tops around where the new lake would be to reduce potential size of the quake induced avalanches will occur in a major earthquake, so that any local 'tsunami' would be less likely to overtop the dam catastrophically. Competent people have reanalysed the result and claim that there is a reasonable prospect that the dam will fail given too probable to be nice circumstances. If you offered me a cheap enough price on an Apricot orchard a mile downstream from the dam I'd happily consider retiring there without and great reference to the dam factor in my reckonings. This does not prove my strong like of surfing but rather demonstrates that people who aregue for the predictability of nuclear waste storage can be about as one eyed in their decision making as I, and as the many current Clutha apricot farmers.
