Oconee ISFSI UFSAR Table A-1 (Page 1 of 1)

Table A-1. Design Parameters for the Oconee ISFSI GENERAL DESIGN REQUIREMENTS Maximum weight on crane hook 100 tons Capacity (Casks/Canister) 24 PWR Assys Maximum assembly weight 1682 lbs Reference Fuel Assembly parameters:

1. Nominal burnup 40,000 MWD\MTU

2. Initial Enrichment (Maximum) 4.0%

3. Maximum initial Uranium Content 472 kg/assembly

4. Cooling Time 10 years nominal

5. Fuel Rod Array 15 x 15 Fuel Cell Envelope (Minimum) 8.75/8.85 in.

Effective multiplication factor Keff < 0.95 Internal DSC atmosphere Inert Gas (Helium)

Ambient temperature -30ºF to 116ºF Solar heat load (Maximum) 127 BTU/hr-ft2 Average doses at HSM surface during storage 20 mr/hr combined gamma and neutron Maximum Axial Midplane Dose at Transfer Cask 200 mr/hr combined gamma and neutron Surface during Transport1 Maximum Loading Height (Fuel Pool) 15' 6" above pool floor Storage orientation Horizontal Normal Operating Equilibrium Clad Temperature 340ºC Assume Credit for Burnup for Criticality Based on 1.45% Initial Enrichment Computations2 equivalent.

Accessible with Fuel Mast Maximum Assembly Length (Includes Radiation 173 in.

Growth and Control Components)

Active Fuel Length 144 in.

Notes:

1. Licensing basis design calculations assume a homogeneous source over the active fuel region (See Section 7.2.1). Elevated dose rates in excess of 200 mrem/hr over limited areas of the transfer cask surface may be observed. In particular, elevated gamma dose rates in excess of 200 mrem/hr, centered on fuel assembly end fittings, can be anticipated based on initial DSC loading dose rate survey data. Supplementary shielding calculations performed subsequent to ISFSI operation demonstrate dose rates as high as 565 mrem/hr centered on fuel or near assembly end fittings can be anticipated.

2. Primary licensing basis criticality control design feature is credit for 1810 ppm soluble boron in DSC cavity during wet loading operations. Fuel assembly initial enrichment/burnup qualification procedures provide additional criticality safety margin.

Notes:

Grid straps are placed on intervals of 21 3/32 +/- 1/16 inch. Thus the maximum interval is 21 7/32 inch. These tolerances do not accumulate. The spacers in the DSC are two inches wide and the fuel grid straps are 1 1/2 inch wide (higher for later zircaloy grid fuel).

Therefore, fuel assembly support will be provided at the grid straps by the DSC spacer discs through the entire tolerance range of 20.97 inches (20 31/32) - 21.22 inches (21 7/32). The nominal value of 21.12 used in Revision 1 of the NUHOMS -24P Topical Report (Table 3.1-2) falls within this range.

2. To ensure safe and secure, long-term containment and criticality control during transfer and storage of IFAs, DSC components are designed, constructed, and tested in accordance with Nuclear Safety Related requirements as defined by 10CFR 50, Appendix B and the DPC QA-1 Quality Assurance Program.

3. Components which are not required to perform a safety function or mitigate the consequences of an accidental radiological release comparable to 10CFR 100 site dose criteria guide values are designed, constructed, and tested in accordance with the DPC QA-2 Quality Assurance Program.

Additionally, the concrete HSMs and foundation are designed to withstand Safe Shutdown Earthquake seismic forces and tornado missiles so as to preclude any interaction with the DSC pressure boundary or loss of shielding Therefore, construction and inspection shall be in accordance with the DPC QA-4 Quality Assurance Program.

1. Monitoring operation - Personnel will be monitoring the operation so that any problems which may arise can be swiftly corrected. The personnel may leave the area if necessary and the operation could be monitored from a remote location out of the radiation field.

2. Estimated times are conservative estimates for personnel working in the radiation field around the cask or HSM.

3. GA refers to General Area and is used to indicate workers in the room or area with the DSC/Transfer Cask to maintain visual control over operations in areas where the dose contribution from ISFSI operations is very low.

1. Slab reinforcement:

a. Bottom mat - #5's @ 6 c-c each way

b. Top mat - #4's @ 6 c-c each way

c. Yield strength = 60 ksi per ASTM 615.

2. Slab thickness = 1'-6 of concrete

3. Concrete strength (28 days) = 4000 psi (minimum)

4. Soil ultimate strength - 12.0 ksf (Based on laboratory testing)

5. Soil elastic modulus = 174 ksf (Based on laboratory testing)

6. Poisson's ratio of soil = 0.3 (Based on soil test data and Foundation Analysis and Design 3rd Ed., Joseph E. Bowles.)
