- a. - No this The first sentence establishes that the HI-STORM requirement System does not create any radioactive materials or from the CoC/TS have any radioactive waste treatment systems. The result in second sentence merely explains that specific operating procedures and reporting is not required 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.
Evaluation Summary Remove This program implements the requirements of 10 CFR 72.44(d) as this is a regulatory requirement that must be met. Also remove Specification 3.1.1, Multi-Purpose Canister (MPC),

Move the rest of the text to Appendix B Section 4, Administrative Controls. The remaining sentences in item a are not a safety concern but should be kept in the CoC Appendix B as they reduce the regulatory burden on the licensees. Item b should be kept in the CoC Appendix B as this program is necessary to assure that the operations involved in the storage of spent fuel in an ISFSI are performed in a safe manner.

accident previously There would only be an increase in the consequences evaluated in the cask of accidents due to increased dose from the FSAR? Overpack or Transfer Cask if there was an area of Risk Insight**: reduced shielding. This protection program verifies Will removing that there is no such area of reduced shielding, but this does not include an overt action involving an SSC that requirement provides shielding.
from the CoC/TS The possibility of a new or No result in different kind of accident being created compared to those previously evaluated in the FSAR?
A Significant reduction in 5.3.2 - No the margin of safety for ISFSI or cask operation? 5.3.1 and 5.3.3 through 5.3.8 - No.

CoC Condition/Technical Specification Evaluation Form - CoC original Appendix A There would be a slight reduction in the margin of safety for the shielding function, but only if an area of reduced shielding exists.
Evaluation Summary 5.3.1 -Retain in Appendix B section 4, Administrative Controls.
5.3.2 - Combine main statement with existing Section 5.3.3 as these discussions are currently repetitive.
Refer to appropriate Part 72 Section: 72.212(b)(5)(iii) 5.3.3 through 8- Retain in Appendix B section 4, Administrative Controls. These controls are important as they provide dose rate information in assessing worker dose and potentially identifying a misload.
