The HI-STORM 100 Cask System does not create any radioactive materials or have any radioactive waste treatment systems. Therefore, specific operating procedures for the control of radioactive effluents 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).

For lifting of the loaded TRANSFER CASK using devices which are integral to a structure governed by 10 CFR Part 50 regulations, 10 CFR 50 requirements apply. This program is not applicable when the TRANSFER CASK is in the FUEL BUILDING or is being handled by a device providing support from underneath (i.e., on a rail car, heavy haul tr ailer, air pads, etc
...) or is being handled by a device designed in accordance with the increased safety factors of ANSI N14.6 and having redunda nt drop protection.
Pursuant to 10 CFR 72.212, this program shall evaluate the site-specific transport route conditions.
- a. For the TRANSFER CASK, the following requirements apply:
- 1. The lift height above the transport r oute surface(s) shall not exceed the limits in Table 5-1 except as provided for in Specification 5.5.a.2. Also, if applying the limits in Table 5-1, the program shall
ensure that the transport route c onditions (i.e., surface hardness and pad thickness) are equivalent to or less limiting than either Set A or Set B in HI-STORM FSAR Table 2.2.9.
- 2. The program may determine lift heights by analysis based on the site-specific conditions to ensur e that the impact loading due to design basis drop events does not ex ceed 45 g's at the top of the MPC fuel basket. These alternative analyses shall be
commensurate with the drop analyses de scribed in the Final Safety Analysis Report for the HI-S TORM 100 Cask System. The program shall ensure that these alternative analyses are documented and controlled.

- 4. The TRANSFER CASK and MPC, when loaded with spent fuel, may be lifted to those heights necessary to perform cask handling operations, including MPC TRANSFER, provided the lifts are made with structures and components operated, fabricated, tested, inspected, and maintained in accordance with the guidelines of NUREG-0612, "Control of Heavy Loads at Nuclear Power

The radiation protection program shall include appropriate controls for direct radiation and contamination, ensuring compliance with applicable regulations, and implementing actions to maintain personnel occupa tional exposures As Low As Reasonably Achievable (ALARA). The actions and criteria to be included in the program are provided below.
5.7.2 As part of its evaluation pursuant to 10 CFR 72
.212(b)(2)(i)(C), the licensee shall perform an analysis to confirm that the dose limits of 10 CFR 72.104(a) will be satisfied under the actual site conditions and ISFSI configuration, considering the planned number of casks to be deployed and the cask contents.
5.7.3 Based
on the analysis performed purs uant to Section 5.
7.2, the licensee shall establish individual cask surface dose rate limits for the HI-TRAC TRANSFER CASK and the HI-STORM VVM to be used at the site. Total (neutron plus gamma) dose rate limits shall be establishe d at the following locations:
- a. The top of the TRAN SFER CASK and the VVM. b. The side of the TRANSFER CASK
- c. The outlet vent on the VVM
5.7.4 Notwithstanding
the limits established in Section 5.7.3, the measured dose rates on a loaded VVM shall not exceed 30 mrem/hr (gamma+neutron) on the top of the VVM.
5.7.5 The licensee shall measure the TRANSFER CASK and VVM surface neutron and gamma dose rates as described in Section 5.7.8 for comparison against the limits established in Section 5.7.3 or Section 5.7.4, whichever are lower.

5.7 Radiation
Protection Program (cont'd) 5.7.6 If the measured surface dose rates exceed the lower of the two limits established in Section 5.7.3 or Section 5.7.4, the licensee shall:
- a. Administratively verify that the correct contents were loaded in the correct fuel storage cell locations. b. Perform a written evaluation to verify whether a VVM at the ISFSI containing the as-loaded MPC will cause the dose limits of 10 CFR 72.104 to be exceeded. c. Perform a written evaluation within 30 days to determine why the surface dose ra te limits we re exceeded.
5.7.7 If the evaluation perfo rmed pursuant to Section 5.7.6 shows that the dose limits of 10 CFR 72.10 4 will be exceeded, the MPC shall not be placed into storage or the MPC shall be removed from storage until appropriate corrective action is taken to ensur e the dose limits ar e not exceeded.
5.7.8 TRANSFER
CASK and VVM surface dose rates shall be measured at approximately the following locations:
- a. A minimum of four (4) dose rate measurements shall be taken on the side of the TRANSFER CASK approximately at the cask mid-height plane. The measurement locations shall be approximately 90 degrees apart around the circumference of the cask. Dose rates shall be measured between the radial ribs of the water jacket.
- b. A minimum of four (4) TRANSFER CASK top lid dose rates shall be measured at locations approximately half way between the edge of the hole in the top lid and the outer edge of the top lid, 90 degrees apart around the circumference of the top lid.
- c. A minimum of four (4) dose rate measurements shall be taken on the top of the VVM. These measurements shall be taken approximately 90 degrees apart around the circumference of the lid, approximately 18 inches radially inward from the edge of the lid.

- d. A minimum of four (4) dose ra te measurements shall be taken adjacent to the outlet vent scr een of the VVM, approximately 90 degrees apart.
5.7.9 The "Radiation Protection Space" (RPS) is a prismatic subgrade buffer zone surrounding a loaded VVM. The RPS boundary is located at a minimum of fourteen (14) feet from the centerline of a loaded VVM located on the periphery of an ope rating ISFSI, and at a minimu m of twenty-one (21) feet from the centerline of a loaded VVM not lo cated on the periphery. The RPS boundary shall not be encroached upon during any site construction activity. The jurisdictional boundary of the RPS extends from the top surface of the foundation pad to the top of the VVM interface pad and the top surface pad. The ISFSI design shall ensure that there is no significa nt loss of shielding in the RPS due to a credible accident or an extreme environment event during construction involving excavati on adjacent to the RPS boundary.
