- SN 2302008 was ultimately installed at Braidwood Pursuant to 10CFR Part 21 § 21.21(d)(3)(i) Paragon is providing initial notification of a defect associated with the Auxiliary Feedwater Pump Diesel Engine fuel injectors supplied to Constellation as noted in the table above. The injectors were provided to Paragon for refurbishment in accordance with the customer purchase orders referenced above. On November 17, 2023, Constellation provided Paragon with Constellation/Braidwood Root Cause Report associated with Issue Report # 4703982 and the associated failure analysis report documenting potential defects with some fuel injectors supplied to Braidwood. The deficiencies reported allowed excessive fuel oil leakage which resulted in diesel lubricating oil system contamination above specified limits. On December 18, 2023, Paragon concluded our evaluation which determined this condition if left uncorrected could contribute to a substantial safety hazard and is reportable in accordance with 10CFR Part 21.
The extent of condition is limited to the Constellation Braidwood and Byron plants.
Paragon has entered this condition in our corrective action program. Affected injectors from PO 01389979 have been removed from service and returned to Paragon. Paragon is coordinating with Byron on recommended actions and will follow up with our final notification on or before 1/17/2024.
