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 availability2766flbliillbdbthdf

• 2766 f ue l assem bli es w ill b e use d b y th e en d o f plant life in 2042

-Requires 75 MPC's (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

• VC Summer -Team Lead. Provide oversight and overall management of the project

• Shaw Group -Architect Engineer. Perform project management, design and implementation

• Holtec International -Provide storage technology, license and hardware. Pool to pad loading services.

• PaRNuclear (Westinghouse subsidiary) -Design, test and install single failure proof cask handling equipment (NUREG 0554)

Loading Plan

-Minimum of 4 MPCs (Multi Purpose Canisters) would have to be loaded every other cycle to maintain full core reserve

• Typical loading campaign will likely consist of 8 MPCs to optimize mobilization and demobilization costs

-First campaign will load 4 MPCs to accommodate learning curve

>>Scheduled to start January 2015

-Anticipate loading 1 MPC and transferring it to the ISFSI per week Chosen Technology

-HI-STORM FW System*After a comprehensive, multi-discipline evaluation of commercial and technical attributes Holtec was the chosen

supplier-Canister capacity is 37 PWR fuel assemblies -HI-STORM FW (Flood and Wind) which was licensed on June 13, 2011

-Canister is licensed for storage and will be licensed for transportation

-Highest heat load capacity (47 kW)

-Suitable for high burnupfuels (68,200 MWd/MTU)

-Can discharge fuel cooled as little as 3 years

-No supplemental cooling required

-Up to 12 damaged fuel containers per canister

-Metamic-HT Basket provides structural and criticality function HI-TRAC VW TRANSFER CASK (ONSITE TRANSFER/TRANSPORT)

• Loaded weight is 290 tons

• Can turn in its own length

• Rubber tires less harsh on haul path ISFSI Site Selection

• Based on an extensive assessment of 4 potential sites presented in a detailed report

-ALARA/dose minimization

-Security*Avoid separate PA (Protected Area)MjiidfPAPAhbdd

• M a jor construct ion outs id e o f PA. PA can t h en be expan d e d to encompass ISFSI and haul path.

-Short haul path

-Minimal hazards -haul path and ISFSI

-Minimal underground utilities

-Close proximity to cask fabrication pad

• Desirable to have this pad outside the Protected Area for easier access to overpack fabrication (assembly and concrete pours)

Berm Major Tasks

• Cask crane upgrade to single failure proof

• Underground relocations (storm drainage, etc.)

• Hydrogentankrelocation

• Hydrogen tank relocation

• Construct haul path and ISFSI pad

• Protected Area expansion Hazards Analysis

• Both the haul path and ISFSI were extensively evaluated to determine hazards for the movement and storage of used fuel casks

-Only substantial hazard identified so far are H2 tanks on the north side of the plantand will be relocated Haul Path and H2 TanksFuel Handling BuildingHaul Road -Looking East Geotechnical & Geophysical Studies

• The haul path and ISFSI have been extensively surveyed*Labanalysesandpreparationofthereport

• Lab analyses and preparation of the report documenting the results is being prepared

-Will be followed by foundation designs Fuel Handling Building Crane Upgrade

• 125 ton bridge crane requires upgrade to Single Failure Proof for handling loaded used fuel casks

• Craneupgradesinclude:Crane upgrades include:-Single failure proof trolley

-All 3 hooks are radio controlled, with pendant backup

-Variable frequency drives

-Power rotating hook VC Summer Fuel Handling Building & CraneOnly the trolley is being replaced 20 Industry Operating Experience (OE)

• All Used Fuel Storage OE are catalogued on the VC Summer SharePoint site and are readily available

-Holtec Information Bulletins are also maintained there

• Someopportunitiestolearn Some opportunities to learn-Concrete and rebar fabrication issues (INPO Event Report 11-4)-Difficulty in meeting ISFSI pad concrete strength range criteria (DC Cook OE32536)
