P 228 PHOTO74665A - Pi PE F-05 PLI JG Fig. 18.13. Plug Formed in Hastelloy N Loop 10 Containing NaF-KF-BF3 (48-3-49 mole %) After 8765 hr at 1125OF. AT= 265OF. 8 ~ . Reduced 23.50%. estimate of the stoichiometry of the deposit is 2NaF-FeF ,-CrF ,-BF,. Metallographic examination of the hot-leg specimens disclosed only moderate surface roughening. Loop 10, fabricated from Hastelloy N, operated without incident for 8335 hr, at which time the hot-leg temperature increased about 50"F, ac- companied by a simultaneous temperature decrease of the same magnitude in the cold leg. A pertur- bation of this type is usually an indication of plugging. The temperature fluctuations ceased after 1 hr, and no further incidents occurred during the life of this loop. The loop was shut down after its 1-year scheduled operation. Examination of the loop piping disclosed a partial plug in the lower portion of the cold leg (Fig. 18.13). The plug, which closed approximately 7 sectional area of the pipe, was emerald green in color and analyzed to be essentially single crys- tals of 3NaF-CrF,.6 Analysis of the drain salt cake from loop 10, Fig. 18.14, revealed extensive increases in the concentrations of Ni, Mo, Fe, and Cr when com- pared with the before-test salt. Nickel was par- ticularly high in the bottom and top portions of 'R. E. n oma, private c WAl L c
