EN Revision Text: INITIAL PART 21 REPORT - DEFECT WITH EATON/CUTLER HAMMER SIZE 4 AND 5 FREEDOM SERIES CONTACTORS
The following information was provided by Paragon Energy Solutions, LLC via email:
"Pursuant to 10 CFR 21.21(d)(3)(i), Paragon Energy Solutions, LLC is providing this initial notification of a potential defect with Eaton/Cutler Hammer size 4 and 5 freedom series contactors that have been modified to include either a special coil and/or to improve the securing of shading coils. These contactors may have been supplied integral to a motor control center (MCC) cubicle or as spare parts. This condition, if left uncorrected, could potentially cause a substantial safety hazard.
"Paragon completed an initial evaluation of a failure of a size 4 freedom series contactor (PN: NLI-CN15NN3A-T16-MOD-M) supplied to Perry Nuclear Power Plant. The reported failure occurred 26 days following installation into its associated MCC Cubicle. Perry identified the screws holding the contact bar to the push bars had fallen out and were laying in the bottom of the molded base. This allowed the movable contact bar to sit on the stationary contacts and significantly degrade due to arcing and then fail in the energized position. This condition could prevent the contactor from performing its safety function to either energize or de-energize the attached load.
"The loose hardware is most likely a workmanship error since the contactor must be disassembled to complete the special coil and RTV modifications to the shading coils. In the fully re-assembled condition, inspection of this hardware for tightness is not possible."
Affected plants: North Anna, Turkey Point, Harris, and Perry.
* * * UPDATE ON 08/25/23 AT 1448 EDT FROM RICHARD KNOTT TO ERNEST WEST * * *
Paragon Energy Solutions submitted their final report in accordance with 10 CFR 21.21(d)(4).
Paragon reported completion of corrective actions including revising the test inspection procedure to ensure hardware tightness during contactor reassembly, identifying all projects containing the affected contactors and verifying appropriate inspections have been completed, restricted use of test inspection procedures issued prior to 8/2/2023 until a formal review is completed, and issued a technical bulletin (TB-Starter-2023-01 Rev 0) for use by affected clients.
Paragon recommends affected licensees perform the steps contained in Technical Bulletin TB-Starter-2023-01 Rev 0 to verify this condition is not present as part of their next routine maintenance outage associated with the affected in use equipment, and at the earliest opportunity for stock spares.
Affected plants: North Anna, Turkey Point, Harris, and Perry.
