Programs 5.0 Certificate of Compliance No. 1032 Amendment No. 65`

Appendix A 5.0-1 5.0 ADMINISTRATIVE CONTROLS AND PROGRAMS The following programs shall be established, implemented and maintained.

5.1 Radioactive Effluent Control Program This program implements the requirements of 10 CFR 72.44(d).

a.

The HI-STORM FW MPC Storage System does not create any radioactive materials or have any radioactive waste treatment systems. Therefore, specific operating procedures for the control of radioactive effluents and annual reporting in accordance with 10 CFR 72.44(d)(3) are not required.

Specification 3.1.1, Multi-Purpose Canister (MPC), provides assurance that there are not radioactive effluents from the SFSC.

b.

This program includes an environmental monitoring program. Each general license user may incorporate SFSC operations into their environmental monitoring programs for 10 CFR Part 50 operations.

c.

An annual report shall be submitted pursuant to 10 CFR 72.44(d)(3).

(continued)

Programs 5.0 Certificate of Compliance No. 1032 Amendment No. 65`

Appendix A 5.0-2 5.0 ADMINISTRATIVE CONTROLS AND PROGRAMS (continued) 5.2 Transport Evaluation Program

a. For lifting of the loaded MPC, TRANSFER CASK, or OVERPACK using equipment which is integral to a structure governed by 10 CFR Part 50 regulations, 10 CFR 50 requirements apply.

b. This program is not applicable when the TRANSFER CASK or OVERPACK is in the FUEL BUILDING or is being handled by equipment providing support from underneath (i.e., on a rail car, heavy haul trailer, air pads, etc...).

c. The TRANSFER CASK or OVERPACK, when loaded with spent fuel, may be lifted to and carried at any height necessary during TRANSPORT OPERATIONS and MPC TRANSFER, provided the lifting equipment is designed in accordance with items 1, 2, and 3 below.

1.

The metal body and any vertical columns of the lifting equipment shall be designed to comply with stress limits of ASME Section III, Subsection NF, Class 3 for linear structures. All vertical compression loaded primary members shall satisfy the buckling criteria of ASME Section III, Subsection NF.

2.

The horizontal cross beam and any lifting attachments used to connect the load to the lifting equipment shall be designed, fabricated, operated, tested, inspected, and maintained in accordance with applicable sections and guidance of NUREG-0612, Section 5.1. This includes applicable stress limits from ANSI N14.6.

3.

The lifting equipment shall have redundant drop protection features which prevent uncontrolled lowering of the load.

4.

For existing handling equipment which does not meet the above criteria, a site-specific drop analysis shall be performed as part of the 10 CFR 72.212 report to demonstrate that the acceptance criteria set forth in the HI-STORM FW FSAR are met. The analysis shall be performed using methodologies consistent with those described in the HI-STORM FW FSAR.
