- 6. In the case of a basic component which contains a defect or noncompliance, the number and location of all such components in use at, supplied for, or being supplied for or may be supplied for one or more facilities or activities subject to the regulations in this part.
VC Summer SKU 30-8091-0920-13, Feedwater Isolation Valve Poppet Seal, is unique to the VC Summer Feedwater Isolation Valves. The poppet seals were designed and manufactured specifically for application in the VC Summer Feedwater Isolation Valves.
There are no other applications of these particular seals in the nuclear industry.
The laminations were identified via microscope inspection in a single batch of poppet seals during a post failure investigation. These seals were manufactured in May 2017 by Infinity Seal of Columbia, South Carolina. Infinity Seal is a commercial grade supplier. VC Summer performs Commercial Grade Dedication of the seals onsite.
VC Summer received two shipments, under two different Purchase Orders, that contained poppet seals. In May 2017 VC Summer received 60 seals (VC Summer Lot Number 7064051). In May 2021 VC Summer received 5 additional seals (VC Summer Lot Number 7081558) from the impacted batch manufactured in May 2017.
At this time there are no other seals from Lots 7064051 and 7081558 installed or in inventory at VC Summer, and none have been delivered to any other facility.
VC Summer performs the Commercial Grade Dedication of these poppet seals. VC Summer does not perform Commercial Grade Dedication of these poppet seals for any other facility.
- 7. The corrective action which has been, is being, or will be taken; the name of the individual or organization responsible for the action; and the length of time that has been or will be taken to complete the action.
All poppet seals from Lots 7064051 and 7081558 have been removed from the Feedwater Isolation Valves and from warehouse inventory. All other Lots onsite have undergone additional testing to ensure that laminations are not present in the qualified seals currently in inventory.
Additionally, Plant Support Engineering is working with the Supply Chain Management to identify the appropriate additional testing and/or inspection to ensure future procurements of Feedwater Isolation Valve poppet seals are free of laminations.
