a. The HI-STORM 100 Version E 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.

The first sentence establishes that the HI-STORM Will removing System does not create any radioactive materials or this have any radioactive waste treatment systems. The requirement second sentence merely explains that specific from the CoC/TS operating procedures and reporting is not required result in based on the first sentence. This is not necessary for safety as implementing the unnecessary procedures and reporting would not decrease any margin to safety for the system. Similarly, the third sentence merely points to an LCO providing additional assurance that the first statement is true.

b. - Yes Without this environmental monitoring program, radioactive material may not be controlled appropriately.
c. - No This statement merely specifies a regulatory requirement that must be met.

5.3.2 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.

5.3.3 Based on the analysis performed pursuant to Section 5.3.2, the licensee shall establish individual cask surface dose rate limits for the HI-TRAC TRANSFER CASK and the HI-STORM OVERPACK to be used at the site. Total (neutron plus gamma) dose rate limits shall be established at the following locations:

a. The top of the OVERPACK.
b. The side of the TRANSFER CASK and OVERPACK
c. The inlet and outlet ducts on the OVERPACK (not applicable for a non-ventilated OVERPACK)
