Moving to ansi ans 3 5 2009
Moving to ANSI/ANS-3.5-2009

  • Conduct review of your existing standard to 2009 for deltas

  • Ensure malfunction testing documentation saved

  • Evaluate Tech Spec and/or USFAR commitments

  • Revise fidelity/configuration management procedures – Use NEI 09-09 R1 as basis for SBT

  • Determine best time to implement

  • Train Ops Instructors, Simulator Staff, Management

  • Practice SBT

  • Implement through letter to NRC Region OL Branch Chief


Moving to ansi ans 3 5 2009 delta examples to consider
Moving to ANSI/ANS-3.5-2009Delta Examples to Consider

  • Test Parameters

    • 1998 & 2009 Steady State test has Charging and Letdown flow but 1985 did not require

  • SBT

    • 1985 not required / 1998 – Check List / 2009 – NEI 09-09 R1 standard

  • Post Event Simulator Test

    • 1985 & 1998 not required / 2009 should be conducted for certain plant events


Moving to ansi ans 3 5 2009 delta examples to consider1
Moving to ANSI/ANS-3.5-2009Delta Examples to Consider

  • Operability Testing (4.4.3.1)

    • Shall be conducted once per reference unit fuel cycle. (Was once per year requirement)

  • Simulator Core Performance Testing

    • More detailed requirements

  • Steady State Test

    • No longer require one hour simulator stability run

    • Comparison done at three distinct power levels spanning at least 50% of operating range


Moving to ansi ans 3 5 2009 data collection
Moving to ANSI/ANS-3.5-2009Data Collection

  • Don’t underestimate the Data Collection and it’s complexity!

    • Defining data collection parameters.

      • Resolution

      • What points

      • What alarm files

    • Maintaining data collected within secure environment (exam related information)

    • Backing up the data, storage location and media.

    • Erasing historical data from unsecure locations.


Fleet considerations
Fleet Considerations

  • How are Fleet Procedures affected by New Standard

  • When are the IP71111.11 inspections scheduled for each site

  • Are there any concerns related to major simulator modification (Outage / Design Changes)

  • Assign simulator lead from each site to the project
