DRAFT FOR DISCUSSION Analysis Method Design Basis Assembly        Topical gives the option of using    State here which design basis  No justification needed assembly from Table 3.1 or 3.2 of assembly was chosen for the topical, this needs to be        source term and transport consistent with what is used in the calculations FSAR SCALE Code Version          Topical allows for newer version      State here which version of    If SCALE version is a newer of the SCALE code system than        SCALE is used to perform        than 6.2.1, provide 6.2.1. If newer versions of the      source term calculations        reference to documentation code are used, topical requires a                                    of comparison per Section comparison per section 3.1 must                                      3.1 be performed Gamma/neutron group          Gamma and neutron group              State if the group structures  Include reference to structures                  structure is documented in Tables from the topical have been          calculation file that includes 3.5 and 3.6 and is allowed to        used or state what the group    justification of different change slightly per Section 3.2      structures are and if they are  group structure and 3.3 of the topical                different; similar to BECT, can be after this table in an appendix to this report Results Acceptance criteria          Dose rates must meet acceptance Include comparison to                Reference calculation file criteria as established in transport acceptance criteria (similar to  with dose calculations method defined in FSAR                FQT, wont fit in this box so may include as appendix, Appendix XYZ to this table, etc.)
Justify acceptance criteria  FSAR will include criteria/method    If there are design changes,    Reference calculation file is valid if there are design for demonstrating that acceptance include results of                  with dose calculations changes                      criteria dose rate points are still  criteria/method used to valid if there are design changes    demonstrate acceptance from FSAR version where these        criteria dose points are still were originally approved              acceptable DRAFT FOR DISCUSSION
 
DRAFT FOR DISCUSSION Example Appendices Appendix A: FQT
[include FQTs with burnup/enrichment/cooling time]
Appendix B: Loading Pattern
[Include loading pattern, locations of damaged fuel, inserts, etc.]
Appendix C: Group structures
[Include gamma and neutron group structures if different from topical]
Appendix D: Acceptance Criteria
[Include results of dose rate calculations demonstrating that acceptance criteria has been met]
