Attachment 3 to Holtec Letter 5014920 Comment Page Line Comment NRC feedback & Holtec Response NRC Disposition No. No. No. Type 1 6 1 Non- OPEN ITEM 1: Provide all temperature values for both the FSAR and proposed TR.
Proprietary Specifically update Tables 2.1 and 4.1 with design basis temperatures and proposed TR temperatures with specific FSAR citations for where those values were obtained.
Clarification Holtec Response: Tables 2.1 and 4.1 of the TR have been revised to cite the exact source (Table number from the FSARs) of component temperature limits. Proposed temperature limits of all components except fuel cladding in Table 2.1 of the TR are consistent with those in Table 2.2.3 and 2.II.2.9 of HI-STORM 100 Amendment 15 LAR.
Similarly, the proposed temperature limits of all components except fuel cladding in Table 4.1 are consistent with those in Table 2.2.3 of HI-STORM FW FSAR. Fuel cladding temperature limits are conservatively set lower than those allowed in the FSAR and ISG-11 Rev 3. Explicit values of all component temperatures from the original source (i.e.
the FSARs) are not duplicated in the TR to avoid convolution of the tables 2 6 5 Non- OPEN ITEM 2: Provide all pressure values for both the FSAR and proposed TR.
Proprietary Specifically update Tables 2.2 and 4.2 with design basis pressures and proposed TR pressures for both the MPC-68M and MPC-32M as well as specific FSAR citations for Clarification where those values were obtained.
The NRC noted during the review that there was a discrepancy between the design basis pressures reported in the FSAR and the pressures reported in the TR with respect to the acceptance criteria. This discrepancy relates to the assertion that acceptance criteria values for the TR will be lower than the design basis acceptance criteria. For the purpose of clarity and information integrity, the NRC would like to see a full comparison (summary table) of the design basis acceptance criteria from the FSARs and the intended acceptance criteria adopted in the TR. Since the acceptance criteria for temperature is also utilized in a similar way to pressure, the NRC would like to see the same comparison.
Holtec Response: Tables 2.2 and 4.2 of the TR have been revised to cite the exact source (Table number from the FSARs) of design pressure limits under all conditions. Proposed MPC cavity pressure limits in Table 2.2 of the TR are consistent with those in Table 2.2.1 and 1.II.2.3 of HI-STORM 100 Amendment 15 LAR. Similarly, the proposed MPC cavity pressure limits in Table 4.2 are consistent with those in Table 2.2.1 of the HI-STORM FW FSAR. Explicit values of all design pressures from the original source (i.e. the FSARs) are not duplicated in the TR to avoid convolution of the tables. Additionally, the design Page 1 of 4
