Why does the Alarm Response Procedure (ARP-8) for RIA-181 0, East Eng Safeguard Radwaste Isolation Vent Radiation Monitor, contain guidance that disallows the operators from selecting the setpoint range to the 1.0E+6 scale?
A. Because the limit setting of Technical Specification 3.3.10, Engineered Safeguards
Room Ventilation (ESRV) Instrumentation, would be exceeded.
B. This action would isolate air flow to and from East Engineered Safeguards, which
will result in the room overheating if the plant is in Mode 1.
C. This action would start P-181 0, East Engineered Safeguards Sample Pump, which
will initiate a diagnostic check of the sample flow path through RIA-181 O.
D. During a Design Basis Accident, RIA-1810 is not capable of providing an alarm
function on this scale.
A. Because the limit setting of Technical Specification 3.3.10, Engineered Safeguards Room Ventilation (ESRV) Instrumentation, would be exceeded.

refer to EI-1, “Emergency Classification and Actions.”
D. have the release terminated by closing MV-CRW172, Discharge to Lake, and refer to EI-8, “Onsite Radiological Monitoring.”

During a Steam Generator Tube Rupture which of the following is an automatic action initiated by RIA-0707 Steam Generator Blowdown monitor and the basis for the action?
The monitor signals the:
A. isolation of both outer bottom blowdown valves (CV-0770, 0771) to limit the spread of contamination in the blowdown system
B. isolation of both surface blowdown valves (CV-0738, 0739) to prevent contamination from reaching chemistry’s sample panel
C. isolation of PCV-6003, Flash Tank T-29A Pressure Control to minimize Main Condenser contamination
D. trip of both S/G blowdown pumps to prevent spread of contamination from the blowdown system
A. isolation of both outer bottom blowdown valves (CV-0770, 0771) to limit the spread of contamination in the blowdown system

The plant is nearing the end of a long production run with elevated PCS activity due to
a failed fuel rod. Operators note a rising sump trend along with elevated counts on the
Containment Gas monitor. The crew enters ONP 23.1 for a PCS leak and the reactor
is manually tripped. During the immediate actions of EOP-1 the NCO at the controls
notes that EK-1363 “CONTAINMENT HI RADIATION” has annunciated.
Based on this alarm which of the following accounts for the above conditions and
describes any required actions?
A. At least one containment radiation monitor has gone into WARNING. Ensure containment is isolated
B. At least one containment radiation monitor has gone into ALARM. No manual actions are required
C. At least one containment radiation monitor has gone into ALARM. Ensure containment is isolated
D. At least two containment radiation monitors have gone into ALARM. No manual actions are required
C. At least one containment radiation monitor has gone into ALARM. Ensure containment is isolated
Correct - This alarm will come in when the first containment monitor goes into
alarm. Containment doesn’t automatically isolate until at least two Containment
Radiation monitors go into alarm. This is a knowledge item from EOP-1 because
an operator is expected to check the monitors when the alarm comes in and
isolate containment if necessary.
During the review of a Liquid Release Order Form HP 6.4-4 the Maximum required
release rate is recorded as 8 gpm for the Filter Waste Monitor Tank T-63. The number
of dilution water and service water pumps has remained constant since the tank=s
sample was pulled. Plant conditions are normal with all systems functioning normally.
As the Shift Manager Reviewer is it acceptable to authorize this release and why or
why not?
A. This liquid release can be authorized because the flow rate is acceptable and the Flow Control Valve will function properly
B. This liquid release shall not be authorized ONLY because the flow rate is such that the Flow Control Valve may not function properly
C. This liquid release shall not be authorized ONLY because the flow rate is such that the Radiation Monitor may not function properly
D. This liquid release shall not be authorized because the flow rate is such that the Radiation Monitor and the Flow Control Valve may not function properly
A. This liquid release can be authorized because the flow rate is acceptable and the Flow Control Valve will function properly

The alarm “PROCESS LIQ MONITORING HI RADIATION” annunciates due to a high
alarm condition on RIA-0707, Steam Generator Blowdown Radiation Monitor.
The following valve positions are subsequently noted:
CV-0704, Blowdown Tank Discharge to Mixing Basin:
CV-0738, ‘B’ S/G Surface Blowdown:
CV-0739, ‘A’ S/G Surface Blowdown:
CV-0770, ‘B’ S/G Bottom Blowdown:
CV-0771, ‘A’ S/G Bottom Blowdown:
CLOSED
CLOSED
CLOSED
OPEN
OPEN
Which of the following is the correct diagnosis of the above valve positions?
A. Per design. S/G sampling capability is maintained through bottom blowdown CVs, and secondary plant contamination is minimized by closing the surface blowdown CVs.
B. Per design. S/G sampling capability is lost since the surface blowdown CVs are closed. Bottom blowdown CVs remain open to allow further trending of RIA-0707.
C. NOT per design. ALL valves should be CLOSED to prevent secondary plant contamination.
D. NOT per design. ALL valves should remain OPEN to maintain full S/G sampling capability.
C. NOT per design. ALL valves should be CLOSED to prevent secondary plant contamination.
CORRECT - Closing of the valves ensures radiation release potential is minimized.
