Liquid rad waste

Question 1

Where does SD water go?

Answer 1

1. Condenser
2. Monitor tank
3. Overboard
4. CST

Question 2

Rule to remember for release valve interlocks (on the release tanks)

Answer 2

Cannot open both tank inlets, both tank outlets, or the inlet and outlet on the same tank at the same time.

Question 3

Flow loop discharge valves for releases are interlocked to ______.

Answer 3

Prevent opening both valves at the same time.

Question 4

Key switched release valves will auto close when ______, key ____ be inserted to operate valve and interlocked with ________.

Answer 4

Must insert key to operate valve
Auto close on release hi radiation signal
Auto close when CW blowdown <10,000 gpm
Interlocked with CW blowdown Reset PB

Question 5

Which rad monitor terminates an overboard release from a release tank?

Answer 5

0PR01J

Question 6

If high radiation occurs from the outlet of the SG blowdown demin/filters, auto swap will occur from flowpaths _____ to the ______.

Answer 6

Condenser
to the
0A, 0B, and (U2)0C blowdown monitor tanks

Question 7

What is overboarding?

Answer 7

Allows blowdown to be directed to the CP trench (river return) instead of the condenser.

Question 8

ALL_____ Auto Close on a ø A Signal or Lo-2 SG level

Answer 8

SD002’s, both units

Question 9

All U-1 _____ Close on a HELB

Answer 9

SD002’s & SD054’s

Question 10

ONLY U-2 _____ Close on a HELB

Answer 10

Lower SD002’s & SD054’s

Question 11

SD007 inlet to the blowdown condenser closes on ______.

Answer 11

13.5 #

Question 12

SD005 sample isolation valve auto closes _____ for both units.

Answer 12

Phase A

Question 13

S/G Blowdown System designed to operate under following conditions:

Answer 13

Primary to Secondary leakage of 1.0 gpm concurrent with clad defects in fuel rods generating 1% of rated core thermal power.
Duration of leak equivalent to 2 full‑power weeks per year of operation.
No circ water to condensate leak.

Question 14

Can you name all the major components in the SD flowpath? (normal and accident)

Answer 14

SD002’s, SD054’s, SD condenser, SD hotwell, SD hotwell Pps, pre-filter, SD demin, after-filter, CP trench or main condenser. If rad monitor in ALARM then flow diverted to SD monitor Tanks.

Question 15

What is the purpose of the Rad Monitor on pump discharge (0PR05J) for the Turbine building fire and oil sump?

Answer 15

Trips all Fire and Oils Sump Pumps
Can be bypassed at 0PL02J (RW Panel)
Must enter LCOAR when bypassed.

Question 16

How is the routine processing of SG blowdown and non-blowdown liquid radwaste different?

Answer 16

Blowdown is normally an open processing system with continuous release. Non-blowdown is a closed system with batch releases.

Question 17

RDCT Pumps operated from 0RE01J: In AUTO, what are setpoints?

Answer 17

80% - Pump _B starts
60% - Pump _A starts
38% - Stops BOTH pumps

Question 18

Containment sump Pumps discharge to __________

Answer 18

Pumps discharge to Aux. Bldg. Floor Drain Tank

Question 19

What is the purpose of the weir boxes?

Answer 19

To allow measurement of leakage in the containment sumps.

Question 20

The containment sump, used to collect unidentified LEAKAGE,
is instrumented to identify leakages of ____ within _____.

Answer 20

1.0 gpm within one
hour.

Question 21

What will satisfy LCO 3.4.15? leakage detection

Answer 21

the containment sump monitor, in
combination with a gaseous or particulate radioactivity
monitor, provides an acceptable minimum.

Question 22

What is the purpose of the Key Locked Valves?

Answer 22

Prevents unauthorized or uncontrolled release of radioactive material to the environment.

Question 23

What are the Normal and Casualty Blowdown rates per S/G?

Answer 23

Normal 45-50 gpm per S/G
180-200 gpm Total

	Casualty	90 gpm per S/G
			360 gpm per Total

Question 24

On a high rad condition on_____ the S/G Blowdown Sample Valves 2PS179A-D (which are downstream of the 2SD005s; see TP-5, SD-2) will close. This will only isolate flow to the _____.

Answer 24

2PR008J

Secondary Sampling System.
