摘要通过在裂变反应堆项目中的广泛测试，已知熔融的Li 2BeF 4与石墨和许多有用的结构金属相容。然而，在作为受控热核反应堆包层冷却剂流体使用时，这种熔融盐的腐蚀可能会因以下因素而增强：（a）磁感应电场的作用，（B）包层中化学嬗变的后果，以及（c）通过流体回路之间的泄漏与其他材料无意中混合。熔盐在强磁场中高速流动时会产生难以忍受的大感应电动势，力（emfs）;在电导率小于Li 2BeF 4的水溶液中感应的电动势的测量被发现甚至在高度湍流的条件下也服从电磁感应的法拉第定律。当然，当气流平行于磁力线时，感应电动势是不存在的，因此应尽可能通过这种气流条件将感应电动势降至最低。在一些地区，Mo…
AbstractThrough extensive testing in fission-reactor programs, molten Li2BeF4 is known to be compatible with graphite and with many useful structural metals. In service as a Controlled Thermonuclear Reactor blanket-coolant fluid, however, corrosion by this molten salt may be enhanced by (a) the effect of magnetically induced electric fields, (b) the consequences of chemical transmutations in the blanket, and (c) inadvertent mixing with other materials through leaks between fluid circuits.Fused salts flowing at high velocity across strong magnetic fields can experience intolerably large induced electromotive forces (emfs); measurements of emfs induced in aqueous solutions with electrical conductivities less than that of Li2BeF4 were found to obey Faraday’s law of electromagnetic induction even under highly turbulent flow conditions. Induced emfs, of course, are absent when the flow is parallel to the magnetic field lines and should be minimized by such flow conditions wherever possible. In regions where mo...
