Answer: A

Off Gas Lesson Plan DRE271 LNOOl, and Annunciator Procedure DAN 903-65 B-5.
Enhance question by modifying choice B to specify the location in systemlplant where Hydrogen gas concentration is decreasing (Off Gas Hydrogen Analyzer).
Answer: C
References:
BWROG EPGsBAGs, DEOP Curves Lesson Plan 295LC-01 Enhance question by changing SRVs to ERVs to gain consistency with Dresden terminology, i.e., ERVs, Safety Valves, or Target RocWSRV (singular) instead of BWROG EPGs/SAGs terminology of SRVs.
Answer: D
References:
DEOP 100, RPV Control, DOA 0600-01, Transient Level Control, and Annunciator Procedure DAN 902-5 D-5 Enhance question by adding verification of discharge inboard and outboard valves to the three choices that mention them. Suggest the three choices read I... Suction and Discharge Inboard and Outboard Isolation Valves... as the 1001-1A&B, -2A,B&C, -
4A,B&C, and -5A&B all receive close signals on Group Ill Isolation.
Answer: A
References:
Tech Spec 3.7.4, DOS 5750-06, Control Room Train A Ventilation Automatic and Manual Smoke Purge System Test, and Control Room Ventilation Lesson Plan DRE288LN003 Remove the question from the exam as it is operationally invalid, since the bulleted information in the stem creates a situation where fuel moves are being conducted with the A Train Smoke Purge surveillance in progress - which is inconsistent with Limitations and Actions of DOS 5750-06, i.e., Control Room Ventilation is considered inoperable while smoke purge is aligned - Refer to Tech Spec 3.7.4.
Answer: D
References:
DOA 1000-01, Residual Heat Removal Alternatives, and Reactor Theory Lesson Plan for Operational Physics Enhance question by re-writing the last statement in stem to add emphasis to both parts of question, i.e., MAINTAIN COOL DOWN RATE, as well as remove LEAST amount of decay heat. In addition, choice C appears to have wrong procedure reference - it should be DOP 1200-02, not 1200-03.
