17. Some nuclear power plants, which are facing space limitation in their spent fuel pool, place older fuel assemblies in steel cylinders, referred to as dry shielded canisters (DSC). The DSC is then hermetically sealed and placed horizontally in- side a concrete bunker, known as the horizontal storage module (HSM). Decay heat is removed by natural convection. Colder air entering the HSM through the inlet screen leaves through the vents located at the top of HSM. The loss coeffi- cient and flow area of the inlet and exit ports are as follows: Inlet port Exit port Fuel Assembly HSM Inlet Port- Kouter screen Kinner screen 0.5 0.5 0.4 0.4 KEnterance/Exit 1.4 1.0 Exit Vent Concrete DSC Area (m²) 0.5 1.0 Total loss coefficient and flow area associated with the flow through the HSM are 2.5 and 0.5 m², respectively. Total rate of decay heat for the DSC is 15 kW. The system thermal length, as defined in Problem 14 is 3.5 m. Air enters the HSM at a temperature of 22 C. Assume air at exit is well mixed. Use the given data to find a) temperature rise, b) flow rate of air through the HSM, and c) total pressure drop from inlet to exit.

Transcribed Image Text:17. Some nuclear power plants, which are facing space limitation in their spent
fuel pool, place older fuel assemblies in steel cylinders, referred to as dry shielded
canisters (DSC). The DSC is then hermetically sealed and placed horizontally in-
side a concrete bunker, known as the horizontal storage module (HSM). Decay
heat is removed by natural convection. Colder air entering the HSM through the
inlet screen leaves through the vents located at the top of HSM. The loss coeffi-
cient and flow area of the inlet and exit ports are as follows:

Total loss coefficient and flow area associated with the flow through the HSM are
2.5 and 0.5 m’, respectively. Total rate of decay heat for the DSC is 15 kw. The
system thermal length, as defined in Problem 14 is 3.5 m. Air enters the HSM at a
temperature of 22 C. Assume air at exit is well mixed. Use the given data to find
a) temperature rise, b) flow rate of air through the HSM, and c) total pressure drop
from inlet to exit.
