| Drywell Floor Drain Sump Monitoring system operability |
|
Definition
| Either the flow or level monitoring portion of the system must be operable. The system consists of a sump discharge flow integrator, one sump level recorder, and one sump fill rate computer point (rate of change). The drywell floor drain sump monitoring system is operable whenever one of these channels is operable. |

Term
| Liquid Radwaste make-up to CSTs flow path |
|
Definition
| From waste collector tank and floor drain collector tank, through waste collector filter, through waste demineralizer to waste sample tanks (2) or floor drain sample tank where the water is sampled. Once the determination that the water is clean is made, it is sent to CSTs. |

Term
| What determines whether condensate drip tank is sent back to main condenser or waste collector tank? |
|
Definition
| "Sent to main condenser if condensate drip tank discharge pressure greater than 10 psig (indicates pump running) and conductivity less than 1 micro-mho. Otherwise, sent to waste collector tank." |
