Background
- VC Summer plant site is located in Jenkinsville SC and is part of NRC Region II. Current site is a single unit Westinghouse 3 loop PWR.
- VC Summer will lose full core offload capability in 2017 without used fuel storage availability
- 2766 ffuell assemblies bli willill b be useddb by th the end d off plant life in 2042
- Requires 75 MPCs (includes emptying fuel pool at the end of plant life)
- Assumes 37 fuel assembly MPC capacity
- VC Summer will utilize a General License for used fuel storage in accordance with 10 CFR 72
Project Responsibilities
