FERMI SEPTEMBER 2004 INITIAL LICENSE EXAM DYNAMIC SCENARIO COMMENTS

1. Source Comment Resolution

1. Scenario No. 1 Event 2 is the only event that requires the SRO to evaluate Inserted malfunction to start a Tech Specs. Per ROI 2003-16, Issue #8, all simulator small torus leak. Required entry Scenario Outline operating tests given after November 1, 2003 require the SRO into TS 3.6.2.2, suppression pool applicants to have at least 2 events that require the use of water level. In addition, required Tech Specs. actions for torus sump level high.

During the exam: noted To ensure that two Tech Sec entries are made, insert an additional TS 3.6.2.3 for RHR in additional malfunction after Event 3 of a small leak in the torus suppression pool cooling which such that the TS lower limit of above minus 2 inches level is was not identified by the facility exceeded. prior to exam. This TS was in addition to the existing TS issue with RHRSW pump malfunction.

2. Scenario No. 1 For Event 2, deleteC(BOP) since the BOP is NOT required to Kept BOP for this malfunction.

3. Scenario No. 1 For Event 4, change C(All) to C(BOP), C(SRO) since the RO Changed as recommended.

does NOT perform any control board actions associated withe Scenario Outline startup of the South Reactor Feedpump (only the BOP does these actions).

4. Scenario No. 1 For Events 8, 10, and 11, add C(SRO) to the Event Type, After major malfunction, it is since the SRO should get credit for all events. understood that SRO is credited Scenario Outline for mitigation actions.

5. Scenario No. 1 For Event 10, there is NO mention of the E and W Bypass Noted as recommended. No valves failed closed on the ES-D-2 forms or the actions credit for the bypass valve Scenario Outline required due to the failure of these valves closed. If there are failures.

NO actions required due to these valve failures, then NO credit can be given for these malfunctions.

6. Scenario No. 1 Level of Detail Comment: For the BOP, include the steps Updated as recommended.

15. Scenario No. 2 For Event 1, delete N(BOP) since the BOP does NOT have Updated as recommended.

16. Scenario No. 2 For Event 3 there are NO RO actions on the control board that Changed malfunction as can be credited for a failure of CRD recommended to allow control Scenario Outline FCV-F002A closed. There are only local operator actions to board mitigating operation by shift the FCV. RO.

Change the malfunction to a failure of the CRD FCV controller in AUTO such that manual control is required to be taken. This malfunction would thus change to I(RO), I(SRO).

17. Scenario No. 2 For Event 5, change the Event Type from M(All) to C(All) for Updated as recommended.

18. Scenario No. 2 For Event 6, add C(SRO) to the Event Type, since the SRO Changed to all. Also, after major should get credit for all events. malfunction it is understood SRO Scenario Outline also responsible for mitigating actions and credited as necessary.

19. Scenario No. 2 For Event 8, there are NO RO control board actions required Malfunction changed as for the RHR Pump A trip. recommended.

20. Scenario No. 2 Since there are NO actions required to be performed by the RO Corrected as noted above, by (and only verifications), then credit for the RO can NOT be changing malfunction that Event No. 4 given for this event. requires RO actions.

22. Scenario No. 2 Editorial: There are 2 pages associated with these Events, but Error corrected.

both are labeled Page 1 of 1". Change so that the first page is Event No. 5, 6, 7, labeled Page 1 of 2" and the second page is labeled Page 2 and 8 of 2".

23. Scenario No. 2 Editorial: In the Event Description at the top of the page, Corrected.

change so that Steamleak in Drywell is listed after Trip of Event No. 5, 6, 7, EDG during startup, so that the events are listed in the proper and 8 numerical order as per the scenario outline.

24. Scenario No. 2 For the BOP, add steps to perform the following using 20.300 Changed to correct initial series procedures: conditions to reflect EDG 11 Event No. 5, 6, 7, - Add steps to restore power back to Bus 72CF. rather than EDG 13 being OOS.

and 8 - Add steps to crosstie Bus 72CF to Bus 72F. Noted steps to check 71CF (First Page) transferred to alternate power source.

25. Scenario No. 2 For the SRO, add an asterisk (to denote a Critical Task for the Incorrect, prior to Torus pressure SRO) to Direct RO to place RHR in Torus Spray prior to reaching 9 psig.

Event No. 5, 6, 7, Drywell pressure reaching 9 psig in accordance with 23.205. is part of critical step for initiating and 8 Drywell sprays prior to reaching (First Page) DWSIL.

27. Scenario No. 2 Inserted a normal evolution for the BOP to take actions to Changed as recommended. But, Event No. 2 prepare the reactor feed pump turbine as a replacement for a during exam administration noted power increase with rods. However, during validation noted that the drain valves were that the actions were all verify and could not give credit to the already open in contrast to what BOP. was expected during the Recommended steps for drain valve manipulations as part of validation. Required the facility the warm up as sufficient for a normal for BOP. to continue with the evolution until steps in the same procedure for turbine warm up required valve manipulations to insert steam and start rolling the turbine. Identified during the exam administration and directed corrections during exam by chief examiner.

28. Both Scenarios Noted no end point for scenario. Post exam changes, adequately noted that at the discretion of the chief examiner the scenario will be terminated.
