Week 1

Question 1

Given the following Reactor Coolant System conditions:
• The plant is at 20% power and stable.
• Chemistry reports RCS Chloride is 0.75 ppm.
The operating crew should….

Answer 1

Restore parameter to within Steady State limit within 24 hours IAW TLCO 3.4.101

Question 2

The plant is at 100% power when CRS discovers that the surveillance requirement (SR) to verify
operable CEA position indicator channels indicate within 5.2 inches of each other was not
performed within the last 17 hours (SR 3.1.5.2).
The required frequency of SR 3.1.5.2 is 12 hours.
The operator should:

A. invoke SR 3.0.3 & LCO 3.1.5 is met, because the SR may be delayed for 24 hours from the time of discovery, by invoking SR3.0.3
B. LCO 3.1.5 is met. The SR must be performed within the next hour or be in Mode 3 in the next 6 hours
C. invoke SR 3.0.3 and immediately declare LCO 3.1.15 not met. Reduce thermal power in accordance with the limits in the COLR.
D. immediately declare LCO 3.1.5 not met & perform the SR

Answer 2

A. invoke SR 3.0.3 & LCO 3.1.5 is met, because the SR may be delayed for 24 hours from the time of discovery, by invoking SR3.0.3

Question 3

Given the following information...
SURVEILLANCE: 
Verify flow is within limits. 
FREQUENCY:
Once within 12 hours after ≥ 25% RTP
AND
24 hours thereafter.

Describe the extensions (if any) that can be applied to the initial performance, and frequency of
this Surveillance Requirement.

Answer 3

The initial performance of the SR cannot be extended.

The subsequent performance can be extended by 25%.

Question 4

The RCS Pressure Safety limit is less than or equal to…

A. 2550 psia.
B. 2650 psia.
C. 2750 psia.
D. 2850 psia.

Answer 4

C. 2750 psia.

Question 5

“The lowest functional capability or performance levels of equipment required for safe operation
of the facility” is the definition of_________.

A. mitigating strategies.
B. safety limits.
C. action statements.
D. limiting conditions for operation. (LCOs)

Answer 5

D. limiting conditions for operation. (LCOs)

Question 6

SURVEILLANCE:
Verify offsite circuit operable.
FREQUENCY:
1 hour
AND
Once per 8 hours thereafter

1200 on 8/1/14 A DG becomes inoperable requiring performance of the above SR.
Assuming that the Operating Crew took the maximum allowed time for the initial performance of
the SR, when does the next subsequent performance of the SR have to be completed?

Assume extensions are used where applicable.
A. 2100 on 8/1/14
B. 2115 on 8/1/14
C. 2300 on 8/1/14
D. 2315 on 8/1/14

Answer 6

C. 2300 on 8/1/14

Question 7

With the Reactor critical in Mode 2 during a Reactor Startup, it is noted that RCS loop T-cold
indications are:
1A is reading 546°F
1B is reading 546°F
2A is reading 543°F
2B is reading 545°F
The most limiting LCO Action for this condition is _______

A. open all RTCB’s immediately.
B. be in Mode 3 in 30 minutes.
C. restore Tcold to >550°F within 2 hours.
D. be in Mode 4 in 6 hours.

Answer 7

B. be in Mode 3 in 30 minutes.

Question 8

• A plant cooldown is in progress.
• RCS temperature is currently 362°F.
• The secondary operator reports RCS cooldown rate for the last hour has been 120°F.
What is the maximum time allowed for the operator to restore the cooldown rate to within limits
per the Tech Spec?

A. immediately.
B. 15 minutes.
C. 30 minutes.
D. 60 minutes.

Answer 8

C. 30 minutes.
