The Blake Rhometer operating range was extended from 600 to 1000 deg F and a variable-orifice plugging meter was developed. Both instruments were evaluated in the Atomic Power Development Associates Scdium Technology Loop against weighed or metered contaminants. The loop injection series included: water, hydrogen, carbon monoxide, carbon dioxide, and methane gases; and tea bag injections of sodium carbonate, sodium hydride, sodium hydroxide, and sodium monoxide. Cover gas was monitored and temperature varied during and after each injection run, and the test loop cleaned by cold trapping after each run. A Continuous Hydrogen Monitor attached to the loop cover gas system and a Nickel Diffusion-Tube Hydrogen Monitor connected to the loop proper were evaluated for sensitivity and response. (auth
