DRMS Flashcards
TRA00022
What is the purpose of DRMS?
Detect, indicate, and record radiation and airborne radioactivity levels.
What are the DRMS components?
G64 RAM
EcoGamma RAM
iCAM (alpha/beta)
PING iCAM (alpha/beta, Iodine, NG)
Horizon System
Control System Infrastructure Cabinets (CSI)
How many G64 RAMS in ATR?
35
How many EcoGamma in ATR?
16
How many mobile iCAMs in ATR?
18
How many iCAM_PING skids in ATR?
6
What is different about CAM4?
Mobile and fixed
Do EcoGammas have local display or alarms?
No. They supplement the G64s in locations because they have a higher detection range.
What components in DRMS are powered by Diesel/Comm?
iCAMs 1-6, 12, 15-17, 19, 20, and 22
G64 RAMS 1, 3-6, 9-12, 14-23, 28, 29,34, 38-40, and 44
What components in DRMS are powered by Instrument UPS?
iCAMs 7-11, 13, 14,18, 21, and 25
RCUs in RCO
G64 RAMs 2, 7, 8, 13, 24-27, 35
What components in DRMS are powered by Dual Power Sources?
CSI Racks
Evac System A and B
What EcoGamma RAMs feed Evac System A?
5, 6, 23, 34
What EcoGamma RAMs feed Evac System B?
2, 13, 24, 35
What is the function of the Horizon Console?
These are remote monitoring terminals. They monitor devices and provide limited control.
What are the two subsystems of the Horizon System?
Horizon OPC (manages comms) and Horizon SCADA (Operator Interface)
Where are CSI servers located?
Severs in RDAS. Two cabinets with 3 systems/servers and a back up in Simulator
How many CSI Cabinets are in the plant?
There are 7 total, 2 in RDAS, 1 in laydown, and 2 each in first and second basements.
Where are the remote monitoring terminals located?
RCR and ECC
Describe the channels for Canberra iCAM.
Particulate - Silon semiconductor detector for a/b with optional second detector for gamma compensation
Iodine - Sodium Iodide detector
Noble Gas - Plastic Scintillation Beta Detector
Flow Path - P-I-NG, Pressure Transducer, Pump
Draw a CAM PING lineup.
Describe the detector in EcoGamma.
Dual halogen quenched GM detector (1uR/hr to 1000 R/hr)
Describe G64 Area Gamma Monitor.
Solid State. 10 uREM/hr to 10 REM/hr
Describe the G64 and EcoGamma RAM light indications.
Solid Green = Operational
Blinking Green 50% = Initializing
Blinking Green 10% = Internal Fault
Solid Red = High Dose Rate Alarm
Blinking Red = Alert Dose Rate Alarm
No LED = No Power
Describe the head arrangement for G64 area monitor.
Detector head can be at the unit or remote up to 100 meters away
