2015 Davis-Besse Initial Licensed Operator Examination Outline Review I. Operating Test A. RO Admin JPMs
RESPONSE
The previous two exams included reactivity calculations all of which test similar knowledge and abilities. Recommend replacement of the selected K/A with one that does not involve a reactivity calculation.
RESPONSE: Selected another K/A (2.1.20) Reactor Water Inventory Balance
- 2. JPM A2 K/A 2.2.13 has been selected and tested on two of the last three exams; was the K/A randomly selected?
RESPONSE
These exams tested the preparation/review of tagouts/clearances.
Recommend selecting a different K/A that doesnt involve safety tagging/clearances.
RESPONSE: Selected another K/A (2.2.15) Use plant drawings to determine how to isolate a leak.
RESPONSE
The previous two exams included review of reactivity calculations all of which test similar knowledge and abilities. Recommend replacement of the selected K/A with one that does not involve a reactivity calculation/review.
RESPONSE: Selected another K/A (2.1.20) Review Reactor Water Inventory Balance
2015 Davis-Besse Initial Licensed Operator Examination Outline Review
- 2. JPM A4 Two of the last three SRO exams have included JPMs to classify emergency events and make notifications. Recommend selecting a JPM that does not involve an emergency classification.
RESPONSE: Selected another K/A Task to initiate notification of ERO.
C. Control Room Systems/In-Plant JPMs - No Comments D. Simulator Scenarios
- 1. ES-301-5 Recommend testing a crew with two ROs and the Upgrade SRO and a crew with two of the SROIs using a Surrogate in the BOP position.
- 2. Scenario 1, Event 6 Evaluate whether BOP should get a NORMAL credit for power reduction.
RESPONSE: Determined that BOP should NOT get a NORMAL credit for power reduction.
- 3. Scenario 1, Event 7 Are the automatic reactor trip functions also disabled? Auto trips must be disabled to take credit for the Critical Task.
RESPONSE: AUTO trips are disabled.
- 4. Scenario 2, Event 7 What is the feasibility of three Nis failing at the same time?
RESPONSE: Highly unlikely, but only way to exercise the AOP action.
- 5. Scenario 2, Event 6/Scenario 3, Event 5 The BOP should probably get credit for a NORMAL evolution associated with the Power Reduction RESPONSE: Will evaluate during validation.
RESPONSE: Determined that BOP should NOT get a NORMAL credit for power reduction.

- 6. Scenario 3, Event 2 Why is response to the PORV leak a Critical Task? Does the leak exceed the capacity of the MU/ECCS?
RESPONSE: Leak does not exceed capacity of MU/ECCS. Reclassified as a non-critical task.
POST EXAM COMMENT - Should have remained a Critical Task, since failure to complete task significantly impacts the mitigation of the subsequent Steam Generator Tube Rupture.
II. Written Exam - No Comments
