ONE INDUSTRY – ONE STANDARD Panel Discussion Transition to ANS/ANSI-3.5 2009 Standard
Panel Members • Tim Vriezema • American Electric Power – DC Cook • First simulator to 2009 Standard • Was on 1985 Standard • Jim Florence • Nebraska Public Power District – Cooper • Currently on 1985 Standard • ANS/ANSI-3.5 Working Group
Panel Members • Bob Soderholm • Dominion - Surry • Dominion currently has 5 Units on 1998 Standard • Fleet Approach • Gregg Ludlam • Exelon • Exelon currently has 8 Units on 1985 Standard • Exelon currently has 1 Unit on 1993 Standard • Exelon currently has 1 Units on 1998 Standard • NEI LOFG Chair
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-3.5-2009Delta 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-3.5-2009Delta 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-3.5-2009Data 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 • 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
