Attachment 6 OBDI 202 - IOLE Process DRAFT OUTLINE COMMENTS Facility:
FC First Exam Date:
Sep 17, 2010 Written Exam Outline (7/12/10)
Comment Resolution 1
Revision number should be at the page level - therefore each page should contain a rev number (could put Rev number in header or footer).
Will do.
2 Is the value of the printout of KAs that are listed in forms 401-2/3 the question number? Will these stay the same throughout the development process?
Yes. Yes.
3 SRO - Tier 2/Group 1: Sys: 062 AC Electrical Distrib, KA 2.4.1 - Knowledge of EOP entry conditions and immediate action steps appears to be an RO KA.
Will review. If necessary, another KA will be selected.
Administrative JPM Outline (7/12/10)
Comment Resolution 1 Reminder to submit original JPMs for those indicated as Modified.
Okay.
2 ES-301-1, Type Code: identify whether C, S, or R Will update ES-301-1. All will be Class(R)oom Control Room / In-Plant System JPM Outline (7/12/10)
Comment Resolution 1
Are JPMs being developed to run concurrently as identified in the schedule? (S1/S2, S3/S4, S5/S6, S7/S8)
Anticipate 3 JPM pairs, two single. Will incorporate into revised schedule.
2 KA and IR for S8 missing fm 301-2 form?
Will add to form.
OBDI 202 - IOLE Process Simulator Scenario Outline Comments (7/12/10)
Comment Resolution 1
Scen 1: Turnover - what is a flow streaming event?
Stratification in core mixing such that Thot indications diverge. Replaced event with a chemistry event. Will consider an I/C event to preclude OP-5 overlap with other scenarios.
2 Scen 1: Event 3 - what verifiable action(s) are performed by the BOP?
Start additional aux fans.
3 Scen 1: Event 8 - does the LOOP lead to loss of vital bus or other complication?
Takes away the condenser therefore altering steaming path (atmospheric dumps). Both diesels start/load. Will look at complications with diesels.
4 Scen 1: Event 6 - How is the bus fault a Normal evolution for the ATCO?
Will evaluate replacing this event with two I/C events.
5 Scen 1: What is the malfunction after EOP entry?
LOOP.
6 Scen 1: What are the EOP contingencies requiring substantive actions?
None. Will update Target Quantitative Attributes (TQA) table.
7 Scen 2: Event 3 - which direction does the channel fail?
Power supply fails, therefore channel will fail low.
8 Scen 2: What are the two malfunctions after EOP entry?
Will change TQA table to 1.
9 Scen 2: What are the EOP contingencies requiring substantive actions?
None. Will change TQA table to 0.
10 Scen 2: What are the 4 AOPs entered?
Events 3, 4, 5. Will change TQA table to 3.
11 Scen 3: What are the 7 malfunctions?
Will revise to include DG2 failure, LOOP to SBO.
12 Scen 3: Event 4 - what direction does channel fail?
Low 13 Scen 3: What are the two malfunctions after EOP entry?
Will update with LOOP/SBO 14 Scen 3: What is the EOP contingency procedure?
Will update with LOOP/SBO 15 Scen 3: Event 6 - what initiates turb trip /
EHC failure 16 Scen 4: Event 3 - What system is FW?
Main Feedwater - 3 electrical pumps 17 Scen 4: Event 8 - what is TCV-909-2?
Steam Dump valve 18 Scen 4: Total malfunctions 7 or 8?
7 - will remove Event 4 since overlap with JPM S3 19 Scen 4: Major transients 2 or 1?
1 - will update TQA table 20 Scen 4: What is EOP entered after SPTAs?
EOP-5, ESD 21 Scen 4: What are 2 contingency procedures?
0 - will update TQA table
OBDI 202 - IOLE Process General Outline Comments (Date)
Comment Resolution 1 Schedule submitted should be marked Rev 0.
Will do.
2 Unable to assess Critical Tasks. For Draft Exam submittal, ensure all CTs meet the requirements of Appendix D, D.1. and have objective success criteria.
Will do.
3 Very thorough outline submittal. One suggested improvement - cross reference of written exam KAs to 55.41/43 and op test KAs to 55.45. This would provide objective evidence for 4.b on Exam Outline Quality Checklist (ES-201-2).
Will consider for next exam.
4 Another suggestion - provide simulator scenario narratives Will consider for next exam.
