A simple bellows pressure detector is connected to a cooling water system.
The detector is located in the reactor containment and has its low pressure side vented to the containment atmosphere.
Current system pressure indication is 100 psig.
If a main steam line break raises containment pressure by 40 psig, the system pressure indication will:
(Disregard any temperature effect on the pressure detector.)
A. increase by 40 psig.
B. increase by the square root of 40 psig.
C. decrease by 40 psig.
D. decrease by the square root of 40 psig.
