Agenda I. On-Line Monitoring (OLM)

II. Research Activities III. Artificial Intelligence IV. Conclusion 3

I. ON-LINE MONITORING Introduction Topical Reports (TR)

Licensing Activities Moving Forward 4

Introduction

  • OLM refers to automated techniques used to assess instrumentation performance or health while the facility is operating
  • It can assist in determining whether the equipment has encountered an anomaly, fault, if recalibration is needed, or in the elimination of unnecessary field calibrations
  • The availability of OLM may result in licensees seeking approval to change surveillance and maintenance practices at nuclear facilities 5

Topical Reports

- Electric Power Research Institute

  • TR-104965 - Guideline for On-Line Monitoring of Nuclear Power Plant Instrument Channel Performance

- Analysis and Measurement Services Corporation

  • AMS-TR-0720R1 - Online Monitoring Technology to Extend Calibration Intervals of Nuclear Plant Pressure Transmitters
  • The Topical Report is intended to be used by licensees and applicants to support plant-specific technical specification changes to switch from time-based calibration frequency of pressure, level, and flow transmitters to a condition-based calibration frequency based on OLM results.

Licensing Activities

  • In addition to evaluation of TRs, NRC has received multiple License Amendment Requests (LAR) on OLM

- Vogtle Electric Generating Plant, Units 1&2

- Joseph M. Farley Nuclear Plant, Units 1&2

- Edwin I. Hatch Nuclear Plant, Units 1&2 7

Moving Forward

  • Ongoing engagement with stakeholders for expected TR submittals
  • Expanded scope for OLM

- Licensing applications

- Research activities 8

II. RESEARCH ACTIVITIES Research on OLM Technical Basis OLM Use Cases 9

  • Validation, Verification, Uncertainty, and Quantification - Black and grey box models
  • Data - criteria for development, retraining
