| Title | Initial Part 21 Report - Deficient Fuel Injectors |
| Event Description | The following is a synopsis of information was provided by the licensee via phone and email:
Pursuant to 10 CFR 21.21(d)(3)(i), Paragon provided initial notification of a defect associated with the auxiliary feedwater pump diesel engine fuel injectors supplied to Constellation. The injectors were provided to Paragon for refurbishment. Constellation provided Paragon with root cause report # 4703982 on November 12, 2023. The associated failure analysis report documented potential defects with some fuel injectors supplied to Braidwood. These reported deficiencies allowed excessive fuel oil leakage which resulted in diesel lubricating oil system contamination above specified limits. Paragon concluded their evaluation on December 18, 2023, which determined that this condition, if left uncorrected, could contribute to a substantial safety hazard and is reportable in accordance with 10 CFR Part 21. The extent of condition is limited to the Constellation Braidwood and Byron plants. Paragon has entered this condition in their corrective action program. Affected injectors at Braidwood have been removed from service and returned to Paragon. Paragon is coordinating with Byron on recommended actions and will follow up with a final notification on or before 1/17/2024.
Paragon Energy Solutions submitted a final report for this event. Notified R3DO (Orlikowski), R4DO (Josey), and Part 21 (email). |
