Particles with lower friction coefficient are more beneficial for tritium extraction
Pressure drop increases with decrease in friction coefficient
Mass flow proportion in internal region increases with friction coefficient
Denser pebble beds, while favorable for high breeding ratio, cause considerable flow resistance
