	What materials can be used to give a 60 year design life to a molten salt heat exchanger in a nuclear reactor? __________________ All living things seek to control their own destiny....this is the purpose of life

	Construction Materials for Molten-Salt Reactors - Energy from Reactors with Molten Salts: Options and Missions - Oak Ridge ... Fluid Fueled Reactors - the Molten Salt Energy Technologies Web Site The last entry is from MIT. It is probably later than the other two. Taking up a new line of work?

	No, just curious as I couldn't come up with something off the top of my head....and was thinking maybe a chemical binding of some sort might mitigate the corrosive qualities of the exchange fluid....not off the table yet,,,,even though I see they have come up with a new alloy INOR-8 that seems to work quite well....so far http://moltensalt.org/references/static/downloads/pdf/FFR_chap13.pdf Yes MIT.... http://www.newyorker.com/online/blogs/elements/2013/06/a-new-way-to-do-nuclear.html __________________ All living things seek to control their own destiny....this is the purpose of life

	The choice of 60 yr as the desired design life is a bit odd. A lesser number could allow the whole reactor to be scrapped while the designers are still hale and hearty, or on the other hand, a 120 yr design life could allow the designers to be safely in bliss before any awkward events might occur. Fortunately stem cell research provides a solution: all interested parties can be cloned (the number of body copies ti be regulated by democratic political action) while the initial "true" copies lie in cryogenic suspension in orbit above the earth. The copies, being free of worry for themselves since their true selves are safe, can pursue the ever increasing need for always more power, making whatever mistakes that are needed to advance knowledge....or not. I like the protective cooled safety plug for the melt-down protected, already melted-down reactor. If the system never malfunctions, it can sit there, providing a gentle warm breeze for local inhabitants, who can spend their time neurally linked on their cell phones playing war games (instead of war). Oops- I strayed off topic. Bye.

	Design lifetimes for heat exchangers are an interesting topic, since the heat/cool cycle rate of the components is affected by the load variations That is, if there are load variations. The tendency to leave generating units on with no significant power production so as to avoid damage from heat/cool cycling leaves the heat exchangers in an odd place, do we try to protect them also? or just make them cheap and replaceable? The heat exchangers are already in an environment with high spatial variations in temperature and materials. that is what they do. I suspect that Henry Ford would say, 'I want some to fail. Make them cheaper'. That doesn't sound so good with radioactive molten salt. Even lowly biofuels can have failure problems with lifetimes for components being in conflict with cost and efficiency
