LAR Discussion Format of LAR - with two vendors, how should the LAR be structured?

LAR Submittal as a Tier 1 for Tricon and ALS with NRC acceptance tied to both vendor topical approvall Confirm review schedule NRC Resources - who and when will they be available for our review Submittal of High Level Documents first before the LAR for review 16

Technical Topics NRC's evaluation of ALS diversity approach -

Risks? Challenges?

Maintenance Workstation Software (non-safety) -

What review will the NRC do and what level of documentation is expected M i t Maintenance Workstation W k t ti is i SIL 1 Time Base Verification - can this be justified without periodic measurement of time base based on how it works (e.g. self-diagnostics)

Use of simple digital components like isolators, signal conditioners with respect to diversity and CCF's RPS/ESFAS Application Software QA 17

Factory Acceptance Test (FAT)

Site Acceptance Test (SAT)

Two Separate FATs before SER Each vendor will perform an FAT How much time does the NRC need after the submittal of the FAT report to issue the SER?

Integrated SAT after SER SAT to verify equipment after shipment and testing of any external interfaces at the Project Integration and Test (PIT) facility Design Verification Test (DVT) before being placed in service 18
