ENCLOSURE 3 M190195 GE2000 SAR Change Summary Table for Enclosures 4 and 5 Non-Proprietary Information
NEDO-33866 Revision 5 Non-Proprietary Information xlii Changes from Revision 4 to Revision 5 are listed in the following table. Revision bars are used for these changes. As indicated below, some of these changes were included to address NRC RAIs (U.S. NRC ADAMS Accession Number ML19296C273).
Location Description of Change (Rev. 4 to Rev. 5)
Reason for Change Chapter 1 Section 1.2.2.1 Changed Item 3.e from 6 wt% to 5 wt%.
In response to RAIs 6.1 and 6.2.
Chapter 5 Section 5.2 Irradiated Fuel Item 4 changed from 6 wt% to 5 wt%.
In response to RAIs 6.1 and 6.2.
Section 5.3.1.1 Included additional clarification for modeling the irradiated fuel source distribution.
In response to RAI 5.1.
Section 5.4.1.1 Removed the word since.
Administrative change.
Section 5.4.1.3 Removed the word since.
Administrative change.
Section 5.4.4.1 Removed enrichment ranges 5.0 E < 5.5 and 5.5 E < 6.0 from Tables 5.4-3, 5.4-4, 5.4-5, 5.4-6, 5.4-7, 5.4-8, 5.4-9, and 5.4-
- 10.
In response to RAIs 6.1 and 6.2.
Section 5.5.1 Removed enrichment ranges 5.0 E < 5.5 and 5.5 E < 6.0 from Tables 5.5-2 and 5.5-5. Updated Table 5.5-4 naming convention.
In response to RAIs 6.1, 6.2, and clarification.
Section 5.5.5 Removed enrichment ranges 5.0 E < 5.5 and 5.5 E < 6.0 from Tables 5.5-33, 5.5-34, and 5.5-35.
In response to RAIs 6.1 and 6.2.
Chapter 6 Section 6.9.4 was added to address RAI 6.1, which resulted in reducing the allowed content U-235 enrichment to 5 wt% and increasing the minimum pellet outer diameter. The initial baseline analyses and general conclusions presented in Section 6.3 through 6.6 remain applicable and were used as the starting point for the Section 6.9.4 analyses. The USL is based on the H/U-235 ratio of the most limiting evaluation; therefore, the USL decreased from 0.9387 to 0.9370. Additional discussions and administrative changes were included in several locations throughout Chapter 6 for the Section 6.9.4 analyses and the changes to the USL.
Section 6.1.2 Table 6.1.2-1 updated to include the most limiting results from Section 6.9.4. Added Table 6.1.2-2 for justification of maintaining the 1750 g U-235 mass limit.
In response to RAI 6.1.
Section 6.3.2 Updated Table 6.3.2-5 to a U-235 enrichment of 5 wt%.
In response to RAIs 6.1 and 6.2.
NEDO-33866 Revision 5 Non-Proprietary Information xliii Location Description of Change (Rev. 4 to Rev. 5)
Reason for Change Section 6.3.2 Removed Notes 2 and 3 below Table 6.3.2-5 for fissile materials that are not applicable to the approved content.
Administrative change.
Section 6.3.4 Updated USL based on a more conservative H/U-235 ratio from Section 6.9.4 analyses.
Corrected the equation H/U-235 ratio calculation equation.
In response to RAI 6.1 and clarification.
Section 6.4.2 Removed statements about the final maximum keff values; these values are determined by Section 6.9.4. Figure 6.4.2-1 updated with new USL value on plot.
Updated Table 6.4.2-2 with the parameters for the cases modeled for fuel rod transport.
In response to RAI 6.1.
Section 6.5.2 Removed statements about the final maximum keff values; these values are determined by Section 6.9.4. Figure 6.5.2-1 updated with new USL value on plot.
In response to RAI 6.1.
Section 6.6.2 Removed statements about the final maximum keff values; these values are determined by Section 6.9.4. Figure 6.6.2-1 updated with new USL value on plot.
In response to RAI 6.1.
Section 6.8 Included a statement to justify the use and applicability of using MCNP6 Version 2.0 for the assessments in Section 6.9.4.
In response to RAI 6.1 and 6.5.
Section 6.8.1 Corrected the number of critical experiments from 69 to 36 and the enrichment from 4.92 to 4.306 weight percent.
In response to RAI 6.3.
Section 6.8.2.2.1 Added Section 6.8.2.2.1 to demonstrate that the benchmark data passes the normality tests.
In response to RAI 6.4.
Section 6.9.1 Clarification on the fuel rod pitch uncertainty. Figure 6.9.1-2 updated with new USL value on plot.
Clarification and in response to RAI 6.1.
Section 6.9.2.1.2 Figure 6.9.2-1 updated with new USL value on plot.
In response to RAI 6.1.
Section 6.9.3 Updated Table 6.9.3-1 to include descriptions for additional MCNP input files. Added Tables 6.9.3-6 and 6.9.3-7 for the MCNP results presented in Section 6.9.4.
In response to RAI 6.1.
Section 6.9.4 Included additional sensitivity studies to assess the criticality effects of changing fuel rod height.
In response to RAI 6.1.
