Why does the loss of reactor coolant pumps during a steam generator tube rupture increase the risk of voiding during the subsequent cooldown and depressurization?
A. The NCS hot legs reach saturation temperature during the rapid depressurization from the tube rupture, causing the NCS to flash.
B. More ECCS flow is injected into the ruptured loop cold leg due to the reduced pressure, resulting in less flow to the core and less heat removal.
C. The upper head region becomes inactive and the fluid temperature in that region significantly lags the temperatures in the NCS loop.
D. The isolation of the steam generator in the affected loop causes that loop to stagnate; therefore, insufficient heat removal capacity is available to cool the NCS.
