Refer to the drawing of a reactor vessel differential pressure (D/P) level detection system that was calibrated at 500 psia (see figure below).
A reactor vessel heatup has resulted in an increase in reactor vessel pressure from 500 psia to 1,000 psia over several hours.
Without density compensation of the level instrumentation, at the end of the heatup, reactor vessel level indication would indicate __________ than actual level because the density of the water in the __________ has changed significantly.
A. higher; reactor vessel
B. higher; reference leg
C. lower; reactor vessel
D. lower; reference leg
