High Energy Arcing Faults Involving Aluminum Components RITF Meeting February 20, 2020 1
Generic Issue on High Energy Arc Fault (HEAF)
- Pre GI-0018 concerning aluminum HEAFs is currently in the assessment phase of the Generic Issue (GI) process.
- The NRC and EPRI established a Technical Working Group to address the issue
- Half of the Low Voltage Cabinets and all the Bus Duct tests were placed on hold based on industrys request to:
- 1) better understand the data
- 2) better formulate a detailed project plan 2
Generic Issue on High Energy Arc Fault (HEAF)
- Continued interaction with EPRI and other stakeholders to evaluate the test data and to estimate the risk from HEAF events using realistic plant parameters.
- The NRC and EPRI also plan to refine the risk method to ensure realistic analyses are performed during assessment.
- Currently working with EPRI to complete a refined survey of electrical enclosures susceptible to High Energy Arc Faults with aluminum to better understand in plant configurations and to bolster the testing realism and applicability.

Next Steps
- NRC staff is in the process of creating a HEAF project plan website where the latest information will be posted to keep the public informed.
Future public meetings/workshops are also planned once all the current test data has been analyzed and a complete project plan has been developed Proposed Timelines and Schedules:
Update GIRP Assessment March 2020. Update will be performed concurrent with Plan the detailed HEAF project plan Project plan March 2020 Survey results EPRI anticipates completion by March 2020 Public meeting/workshop June 2020 Next set of tests Will align with NRC/EPRI WG findings and results and with (as needed) availability of KEMA facility Potential for Q4 2020 / Q1 2021 4
