Description:	Special Report Abstract: This study considers the analysis and conceptual design of an ice-water heat sink for use with a 1500 kw nuclear power plant applicable to hardened underground installations. The purpose of the heat sink is to contain the waste heat from the power system during a period in which the installation is completely sealed off from dependence on any surface facilities. An ice-water heat sink system is a very attractive concept due to the large amount of heat associated with the melting of ice. This study is based, to a considerable extent, directly on the results of prior work, and is intended to provide additional information on configuration parameters and system performance to permit development of a practical system design. Two alternative heat sink configurations are recommended for the prototype design: an annular flow heat sink and a top surface melting heat sink. A high level of confidence is placed in the predicted performance of the annular flow configuration. The top surface melting configuration is considered superior in terms of meeting the design objectives, but its predicted performance is based on assumptions that, although reasonable, must be verified by experiments.
