CVCS

Letdown originates from what location?

• A RCP Suction

• B RCP Suction

• C RCP Suction

• D RCP Suction

What is the approx. temp. and press. of letdown as it leaves the RCS?

• 650 deg. F; 2500 psig

• 590 deg. F; 2000 psig

• 550 deg. F; 2200 psig

• 550 psig; 2200 deg. F.

460 deg. F on the outlet of the Regen HX will cause what to happen?

• Isolate letdown rad monitor

• Isolate letdown

• Alarm only

• Alarm and isolate letdown to rad monitor

At what temp. on the outlet of the regen HX will letdown isolate? (Number Only, no units)

The Regen HX is cooled by what?

• CCW

• ACW

• Charging

• Letdown

Relief valves in the CVCS system are directed where?

• Aux. Bdlg Sump

• Turbine Bldg Sump

• Hold-up Tanks

• Regen Waste Tanks

What is normal letdown flow (approx.; number only)

Flow through the letdown rad monitor is kept between what two values?

• 1-2 gpm

• 0-0.5 gpm

• 0.5-1.5 gpm

• 0.5-1 gpm

What happens to CVCS if temp on the outlet of the letdown HX reaches 145 deg. F?

• Isolates letdown and secures charging pumps

• isolates DI's and diverts to BMS

• Isolates rad monitor and bypasses DI's

• Swaps charging pump suction to RWT

The Letdown Divert valve will swap from the VCT to BMS at what percent level in the VCT?

• 44 gpm

• 5%
