|---|---|
 State the purpose of the process radiation monitoring system. | To monitor radiation levels in the various process and effluent gas and liquid streams, and the primary containment drywell. |
| Identify the systems monitored by the PRM system. | 1. Main steam line RMS 2. Reactor Building ventilation exhaust plenum RMS 3. Control room fresh air intake RMS 4. Standby service water 5. Air removal 6. Off-gas 7. Reactor building elevated release 8. Turbine building elevated release 9. Radwaste building elevated release 10. RCC 11. Radwaste effluent 12. CW & TSW 13. Primary containment leak detection LOCA |
| State the automatic actions associated with the Offgas Post-Treatmet RMS upon sensing high radiation levels. | High trip results in OG-V-45 closes (treat), OG-V-51A,B,C,D open. HHH or HHH and downscale or both downscale results in OG-V-60, OG-V-23, 34A/B, & 54 to close. |
| State the automatic actions associated with the CW blowdown RMS. | Monitors the radioactivity of the CW blowdown line to the river and initiate an isolation of this line upon detection of a high radioactivity level. |
| State the automatic actions associated with the Radwaste effluent RMS. | Monitor radioactivitiy of the radwaste effluent to the CW blowdown line and initiate an isolation of this line upon detection of a high radioactivity level. |
| State the automatic actions associated with the RCC water RMS. | RCC-V-101 will auto close on RCC high rad. |
| State the automatic actions associated with the mechanical vacuum pump discharge RMS. | 3 mR/hr causes both mechanical vacuum pumps to trip. Suction and discharge valves auto close on pump trip. |
| State the automatic actions associated with the main steam line RMS. | Hi-Hi trip or INOP (2.864 x normal) A OR C - Trips AR-P-1A & AR-EX-1A B OR D - Trips AR-P-1B & AR-EX-1B A AND B - RRC-V-20 closes C AND D - RRC-V-19 closes |
| State the automatic actions associated with the reactor building exhaust plenum RMS. | A AND B, or C AND D causes alarm on P602 and a "Z" signal trip. |
| State the automatic actions associated with control room HVAC RMS. | High-High alarm automatically: 1. Closes associated division fresh air inlet damper WMA-AD-51A(B)-1. 2. Stops toilet/kitchen exhaust fan WEA-FN-51. 3. Closes outlet damper WEA-AD-51. |
| State the automatic features associated with the sample line isolation valves for the containment leak detection noble gas and particulate radiation monitors in sample rack CMS-SR-20 & 21. | Isolate on an F or A signal. |
| List the power supplies for the Reactor Building Exhaust Plenum RMS. | A and B - IN-3 C and D - IN-2 |
| List the power supplies for the main steam line RMS. | A and C - RPS-A B and D - RPS-B |
