Flashcards in Radioactive Drains Deck (12):
1

Where are wastes collected by the RD system sent?

to the LRS for processing

2

What areas is the RD system used to detect leakage in?

RCS, refueling pool, ESF equipment, and spent fuel pool

3

Where are the containment sumps and the reactor cavity sump vented to?

the containment building atmosphere

4

What flows into the ESF sumps?

drains from:
SDHX room
CS pump room
HPSI pump room
LPSI pump room
Pipe chase area room

5

How many ESF sump pumps are there?

2 trains, 2 sumps with 2 pumps each sump, so 4 pumps

6

Where is the non-ESF sump vented to?

the aux building HVAC exhaust duct

7

Which sump does the Charging Pump Oil Drain tank drain to?

The radwaste building sump. It is then pumped out of the tank with a portable pump to a 55 gallon drum.

8

What drains into the fuel building sump?

floor and equipment drains from throughout the fuel building
cask decon pit drain
fuel pool liner plate leak detector compartment
cask pit drain

9

What drains into the HUT area sump?

RMWT, holdup pump room and refueling water tank overflows
HUT overflow

10

Where is the decon/laundry sump located?

unit 1 only and it pumps to the chemical drain tanks

11

What is the power supply for all the RD pumps?

NH

12

What happens to the RD system on a LOCA outside of containment?

The control room isolates the flowpath from the ESF and Non-ESF sumps to the radwaste building because we are not analyzed for this leakage outside the Aux building.
