Subject:
Interim Report Regarding a Potential Defect with Schneider Electric Medium Voltage VR Type Circuit Breaker Part Number V5D4133Y000.
Pursuant to 10CFR 21.21 (a)(2), Paragon Energy Solutions, LLC is providing this interim notification of ongoing analysis for Part 21 reportability of a potential defect with the subject circuit breaker part number V5D4133Y000.

CatID/Item QTY Duke-Oconee 156762 001 881325 8
Note: Paragon is currently evaluating the extent of condition as it pertains to other plants and equipment that may utilize the same or similar circuit breakers.
Condition being evaluated:
On February 15th, 2024, Paragon completed initial documentation of a potential defect with the subject circuit breaker in which Duke-Oconee had identified failure to close on demand or delayed operation to close with extended application of the remote closing signal. Since the primary safety function of the circuit breaker is to close and maintain continuity of power to downstream loads, failure to close could potentially contribute to a substantial safety hazard.
This is the first reported instance of this failure mode, and Paragon suspects the issue to be related to aging of the circuit breakers lubrication. Paragon requires more time to complete our testing and analysis to confirm the failure mode and determine reportability.
Date when evaluation is expected to be complete: 5/03/2023.
