LOT 203.11 LWPS

Question 1

• LOT 203.11 LWPS*
• • *

The Spent Resin Processing subsystem consists of a High Activity and a Low Activity Spent Resin storage system. What plant demins does each accomodate?

Answer 1

• High Activity:*
• *CVCS Mixed Beds / Cation Bed**
• *Recycle Evaporate Feed Demins**
• *Concentrated Boric Acid Demins**
• *S/G B/D Demins**
• Low Activity:*
• *Boron Thermal Regen Demins**
• *SFP Demins**
• *Recycle Evaporator Condensate Demins**

• Note:*
• The purpose is to transfer resin w/o generating a lot of liquid waste and to provide decay time before resin is transported offsite for burial.*

Question 2

• LOT 203.11 LWPS*
• • *

What are the three methods for processing liquid waste?

Answer 2

• *Filtration**
• WHT (52’ MAB)*
• Laundry Hot Shower Tank (10’ MAB) [Dummy]*
• FDT(52’ MAB) [Dummy]*
• Condensate Polishing Waste Collection Tank (52’ MAB) [Dummy]*
• *Demins**
• WHT Purification Demin (52’ MAB)*
• LWPS Aux Demin (52’ MAB)*
• Waste Evaporator Condensate Demin (52’ MAB)*
• *Evaporation**
• Not Used at STP*

Question 3

• LOT 203.11 LWPS*
• • *

What water sources drain into the WHT?

Answer 3

• Normal:*
• *Primary Sample Drains**
• 100 gpd*
• *MAB Gravity Drains**
• Filters / Demins*
• Alternate:*
• *RCDT**
• *Containment Normal Sump**

WHT should only be going up ≈ 100 gpd.

Question 4

• LOT 203.11 LWPS*
• • *

Where are the tanks in the LWPS physically located?

Answer 4

• 10’ MAB South Wall:*
• *Laundry/Hot Shower Tank (1)**
• *FDT (1)**
• *CPRWCT (1)**
• *WHT (1)**
• *Waste Evaporator Condensate Tanks (2)**
• Not Used*
• *WMTs A/B/C**
• Vented to their room*
• Outside MAB South End:*
• *WMT D/E/F**
• 4’ FHB:*
• *LWPS Surge Tanks (2)**
• Vented to their room*

Pumps are located in areas around tanks

• Note:*
• Most tanks in the LWPS including WMT D/E/F are vented plant vent header.*

Question 5

• LOT 203.11 LWPS*
• • *

What system does the LWPS use to discharge water?

Answer 5

OLACW

CWS

Activity - High on RT-8038 will terminate discharge (FV-4077) and send water back to respective WMT. (Long path recirc)

Question 6

• LOT 203.11 LWPS*
• • *

What is the difference between an influent tank and an effluent tank?

Answer 6

• Influent Tank:*
• *Receive waste from system and store it until processed**
• WHT, LHST, CPRWCT, FDT, Surge Tanks (2)*
• Effluent Tank:*
• *Receive processed liquids and store it until released/recycled**
• WMTs (6)*

Question 7

• LOT 203.11 LWPS*
• • *

What is the function of the WHT?

Answer 7

Collects Reactor Grade leakage and other tritiated and aerated water sources

• Note:*
• Non-Reactor Grade water goes to Condensate Polishing Regeneration Waste Collection Tank (George Tank)*

Question 8

• LOT 203.11 LWPS*
• • *

For an unprotected outdoor tank, what is activity limited to? (LCO 3.11.1 Liquid Holdup Tanks)

Answer 8

• *≤ 10 Curies**
• Excludes Tritium and entrained Noble Gases*

LCO N/A to WMT D/E/F b/c they have a berm.

Used for temporary tanks.

Question 9

• LOT 203.11 LWPS*
• • *

Where does each tank in the LWPS get pumped to?

Answer 9

• WHT:*
• *FDT (CPRWCT)**
• Uses Demins/Filters*
• CPRWCT:*
• *FDT**
• Only Strainers*
• Surge Tanks:*
• *FDT (CPRWCT)**
• Only Strainers*
• LHST:*
• *WMT C**
• Only Strainers*
• FDT:*
• *WMT D/E/F**
• Strainers / ALPS*
• RHTs:*
• *WMT D/E/F**
• ALPS*
