The pressure within a cooling water system is 100 psig, as indicated by a bourdon tube pressure detector.
The cooling water system and the detector are located inside a reactor containment building.
The pressure detector case is vented to the containment building, which is currently at atmospheric pressure.
If a steam line rupture raises the containment building pressure by 20 psi, the cooling water system pressure indication will…
(Disregard any temperature effect on the detector.)
A. decrease to 80 psig.
B. decrease by an undefined amount.
C. increase to 120 psig.
D. increase by an undefined amount.
