97. A LOCA that resulted in significant core damage occurred at 1600 hours0.0185 days 0.444 hours 0.00265 weeks 6.088e-4 months . ContainmentPressure and Radiation levels were recorded as follows: Radiation Pressure Time (R/Hr) (psig) 1600 420,000 6.2 1630 420,000 6.2 1700 350,000 5.8 1730 280,000 5.3 1800 260,000 4.8 1830 120,000 4.6 1900 90,000 4.3 1930 90,000 4.0 2000 90,000 3.9 At 2000 hours0.0231 days 0.556 hours 0.00331 weeks 7.61e-4 months , while performing Emergency Operating Procedures, a step isencountered which states "Check PZR level - GREATER THAN 20% [24%ADVERSE]".

Which ONE of the following describes the required Pressurizer level and why?20% because the Containment Radiation levels are no longer above the Adversesetpoint requirement.

24% because adverse values must be used until evaluated for lasting effectsbecause the integrated dose limit has been exceeded.24% because adverse containment exists due to the current containment radiationdose rate.

20% because the Containment Pressure is no longer above the Adverse setpointrequirementA.B.C.D. Page 97 of 100 Test Date: 7/2/2010 Cook 2010 NRC Examination

98. Which ONE of the following responses correctly reflects the bases for Reactor CoolantSpecific Activity in Technical Specifications?The short-lived radioactive isotope fission products will have decayed prior to anyfuel movement.

Limitations on specific activity in the RCS reduces corrosion product activation andsubsequent RCS integrity challenge.

During a LOCA the dose will NOT exceed the 10CFR20 limits at the site boundary.During a steam generator tube rupture the release of activity through theatmospheric relief valves will NOT exceed 10CFR100 limits.A.B.C.D. Page 98 of 100 Test Date: 7/2/2010 Cook 2010 NRC Examination

99. Given the following conditions on Unit 2:

A LOCA has occurred

The STA is monitoring the Critical Safety Functions and notes the followingindications: o WR log power 0% o WR startup rate Negative o Containment Pressure 13 psig o CETC's 5 highest 760°F o RVLIS Narrow Range 76% o Pressurizer Level 0% o RCS Pressure 480 psig o AFW Flow 300 x103 pph SG21 SG22 SG23 SG24 o Narrow Range SG Levels 12% 15% 16% 12%Given the conditions described above, to which ONE of the following proceduresshould the SRO transition?2-OHP-4023-FR-C.2, Response to Degraded Core Cooling2-OHP-4023-FR-I.2, Response to Low Pressurizer Level2-OHP-4023-FR-Z.1, Response to High Containment Pressure2-OHP-4023-FR-H.1, Response to Loss of Secondary Heat SinkA.B.C.D. Page 99 of 100 Test Date: 7/2/2010 Cook 2010 NRC Examination 100. Given the following conditions on Unit 2:

The unit has tripped and experienced a safety injection.

While performing 2-OHP-4023-ES-1.2, Post LOCA Cooldown and Depressurization,an ORANGE path condition was noted for the Core Cooling Critical Safety Function.

2-OHP-4023-FR-C.2, Response to Degraded Core Cooling, was entered. While performing steps of this procedure, the Shift Technical Advisor reports thefollowing:

RED path condition exists for Core Cooling Critical Safety Function.

RED path condition exists for Containment Critical Safety Function.

NO other abnormal conditions were noted. Based on these plant conditions, which ONE of the following is the appropriate actionfor the Unit Supervisor to take? Complete actions of 2-OHP-4023-FR-C.2, Response to Degraded Core Cooling,and then transition to 2-OHP-4023-FR-Z.1, Response to Containment HighPressure.

Complete actions of 2-OHP-4023-FR-C.2, Response to Degraded Core Cooling,and then transition to 2-OHP-4023-FR-C.1.

Stop performing 2-OHP-4023-FR-C.2, Response to Degraded Core Cooling, andimmediately transition to 2-OHP-4023-FR-Z.1, Response to Containment HighPressure.

Stop performing 02-OHP-4023-FR-C.2, Response to Degraded Core Cooling, andimmediately transition to 2-OHP-4023-FR-C.1, Response to Inadequate CoreCooling.
