Feedback on how to write LAR to help Tier 3 to 1 change NRC Status of Tricon Topical Report NRC Status of ALS Topical Report Factory Acceptance Test expectations
LAR Status Sections 4.1, 4.6, and 4.7 Drafted Drafting of other sections are in progress Some Phase 1 vendor documents still required 3
required LAR can be submitted about 30 days after the Tricon v10 SER is issued
ISG-06 Enclosure B Matrix See handout 4
Feedback on LAR Draft Sections Draft LAR sections 4.1, 4.6, and 4.7 Level of detail adequate to meet LIC-109/Staff SE Do Figures 4 7 4 8 and 4 11 include all the 5
Do Figures 4-7, 4-8, and 4-11 include all the info needed?
Is section organization/number written to support efficient approval?
Any other comments or suggestions?
Discussion on D3 Topical Assumptions April 19, 2011 Safety Evaluation requires two DI&C-ISG-02 positions to be addressed in LAR Position 4 - Effect of Common Cause Failure 66 Position 7 - Single Failure LAR Section 4.9.2.1.1 to address single failure and FMEA for partial Tricon/ALS failures
LAR - Tier 3 to 1 for ALS Recommendations on how to write the LAR to help convert from a Tier 3 to a Tier 1 77
NRC Audits NRO did an audit on CS Innovations for the AP1000 project Will audits by other divisions of the NRC be shared to not duplicate efforts?

Factory Acceptance Tests Two FATs - FAT for Tricon and a FAT for ALS ALS All Protection Set Core Logic Boards Identical for Core A All Protection Set Core Logic Boards Identical for Core B Does the NRC need to witness the FAT for all Protection Sets?
T i 11 Tricon Protection Sets have different software/loops - tests for each Two Identical Units Write software once, Install Twice Exact same software (Tricon) between Unit 1 and Unit 2 Exact same hardware (Tricon and ALS) configuration Does the NRC only want to witness the first units FAT?
ISG-06 Phase 1 Documents The Software Design Specification (SDS) and the Software Test Plan (STP) are documents from the Design Phase All other ISG-06 information required by ISG-12 All other ISG 06 information required by ISG 06 Enclosure B are Concept and Requirement Phase documents Would it be more appropriate to move the SDD and STP to Phase 2?
