Operation of a Haynes Alloy NO. 25 Forced Circulation Loop to Study the Effects of Hydrogen in a Simulated Sunflower System
Abstract
As part of an effort to answer some of the questions pertaining to the Sunflower system, a forced circulation mercury loop was designed, constructed, and operated. The primary objectives of this "work-horse" loop were: 1) Evaluate the hydrogen swallowing capability of the Sunflower mercury transfer pump. 2) Evaluate the effectiveness of various separators in removing hydrogen from the system. 3) Evaluate the effectiveness of a getter-type corrosion product separator in removing corrosion products from the system. 4) Determine the corrosion and mass transfer which occurred during operation of the The centrifugal pump was evaluated separately from the loop for its ability to accept both single bubbles of hydrogen and a constant flow of hydrogen. During these tests, no distinct correlation could be found for either case between the pump performance and the amount of hydrogen entering the pump. Also, a centrifugal hydrogen separator was evaluated during the operation of the centrifugal pump. Attempts were made to remove hydrogen through a columbium or 1010 steel diffusion window mounted in the separator. However, these attempts met with limited success primarily because of the lack of adequate data on the permeability of columbium to hydrogen at low temperatures and oxidation of the outer surface of the diffusion window.
