. The lower frequency estimate for nonoverpacked leaking rockets is due to the lower peak heat generation and slightly higher heat losses for nonoverpacked rockets compared with overpacked rockets.

However, although gelling also seems to occur preferentially in -RS lots, the gelling mechanism now appears to be related to GB hydrolysis, which produces acidic species that react with the aluminum casing to produce aluminum phosphonate species, which, in turn, serve to link hydrolyzed GB molecules and form a viscous gel (Wagner, 2001~.

ASSESSMENT OF PROCESSING GELLED GB M55 ROCKETS AT ANNISTON slightly higher than the estimated risk of autoignition mentioned previously, but still relatively low. Nonetheless, the frequencies for these natural occurrences indicate that prompt disposal is the proper course of action.
