Abstract
Presented in this report is the transient thermal analysis of the cooldown of a solid cryogen when the pressure in the system is decreased. The method of analysis is discussed, and results consisting of time-temperature histories and the amount of solid cryogens vented from a two stage methane/ammonia cooler during the cooldown are presented.
