Soli Radwaste Flashcards
What are the four subsystems comprised solid Radwaste system ?
-Spent Resin Transfer
-Wet Waste Processing
-Dry Waste Disposal
-Filter Handling & Disposal
What’re the two facilities which supplement solid waste management ?
-Dry Waste Processing & Storage(DAWPS)
-Low Level Radioactive Material Storage Facility
What does the Dry Active Processing & Storage facility provide ?
-Provides centralized location to handle,process,package,& store of radioactive trash
What does the Low Level Radioactive Material Storage Facility provide ?
Provides interm storage capacity for radioactive material prior to reuse,shipment for processing or disposal, or transfer to other licensees
Where does SR system receive Ion Exchanger Resin from ?
-LR system
-Chemical & Volume Control system
-Fuel Pool Cleanup
How is Spent Resin Processed ?
Spent Resin is sluiced to a liner or High Integrity Container(HIC), then dewatered & dried with Resin Drying system
What system do the Local Control panels for SR provide centralized control of equipment in SR system ?
-Radwaste Control Room Instrument Cabinet
-Solidification panel
What remote operated equipment can be control from SR Control Panel ?
-Resin Trasnfer/ Dewatering pump
-RMW for resin transfers & system flushing
What happens in Main Control Room if there is an alarm inside the Radwaste Control Room ? What is the time delay for the trouble alarm ?
-There will be a trouble alarm in the Main Control room
-If alarm in Radwaste Control Room is acknowledged in 5mins, then no trouble alarm in Main Control Room
What’re the Spent Resin Tanks used for ?
1 High Activity & 1 Low Activity are provided to holdup spent resin for decay prior to Wet Waste processing
What kind of resin does the High Activity Spent Resin Tank have ? What Ion Exchangers does it normally receive spent resin from ?
-Receives any resin that exceeds 500mr/hr
Spent Resin:
-CH Ion Exchangers
-PC Cleanup Ion Exchangers
Where does the Low Activity Spent Resin Tanks normal receive spent resin from ?
Receivers Spent resin from:
-LR Adsorption Bed & Mixed Bed Demineralizes
How is resin removal accomplished ? What is backup to fluidize spent resin tank beds ?
-Line inside a line which provides sluice water & sluices it out
-Air & Nitrogen are backup methods for Fluidizing
What is the Spent Resin Transfer/Dewatering Pump used for ?
-Used to transfer resin from Aux.Building & Radwaste Building Ion Exchangers to Spent Resin Tanks
-Transfers contents Spent Resin Tanks to Resin Drying system
What is the Resin/Dewatering Pump powered from ?
Powered from NH
