Heat exchangers storage type

Answer Review the plant s design to determine how radioactive water could get from the plant to the river. Some ways are i) through the heat exchanger and through the condenser, ii) from the closed circuit water into the service water, iii) from the spent fuel storage pool, and iv) from the sump. Prepare fault trees or adapt existing fault trees to determine the probability of each of these release paths. Obtain reliability data for the components that are involved and evaluate the fault trees to determine the probability of each type of failure. For those pathways with a probabilit >7/y,... 

Ce = the total delivered cost of all the major equipment items storage tanks, reaction vessels, columns, heat exchangers, etc., fi = the Lang factor , which depends on the type of process. 

From the modular type it is not far to the heat exchanger type. Instead of using PCM modules there is a storage container with an internal heat exchanger (Figure 147). 

A rare type of storage is the direct contact storage (Figure 150). Direct contact storages have similar performance than heat exchanger type storages however... 

A set of curved tube or coil in which refrigerant or glycol solution run is installed in a tank and cooled inside of the coil. Ice is formed on the surface of the coil and melted from boundary between ice and water. Stored heat is usually recovered by supplying water directly to secondary system. Some systems use heat exchanger to reduce water head loss. This type of ice storage...

A second kind of problem encountered in heat exchanger analysis is the determination of the heal transfer rale and the outlet temperatures of the hot and cold fluids for prescribed fluid mass flow rales and inlet temperatures when the type and size of Ihe heat exchanger are specified. The heat transfer surface area of the heat exchanger in this case is known, but Ihe outlet temperatures are not. Here the task is to determine the heat transfer performance of a specified heat exchanger or to determine if a heat exchanger available in storage will do the job.
