==Subject:==
Supplement to License Amendment Request (LAR) 14-04, Request to Adopt ASME Code, Section Ill, 1980 Edition (No Addenda) as an Alternative to Current Code of Record (TAC No. MF4160)

==References:==
See Page 3 This letter is providing a revision to Appendix F, Table F-1 of the Fort Calhoun Station, Unit No. 1, Updated Safety Analysis Report (USAR) as submitted by Reference 1 and revised in References 3 and 5. The Omaha Public Power District (OPPD) discussed this issue with NRC staff during a teleconference on June 17, 2015. OPPD has revised Appendix F, Table F-1 by deleting (i.e., striking out) the reference to footnote (d) from Load Combination 2 because the application of footnote (d) could be interpreted incorrectly. As currently written, the application of footnote (d) to Load Combination 2 could be construed to indicate that fluid transient loadings only need to be applied to the pressurizer relief valve piping and supports, which is incorrect. Fluid transient loadings should be applied to all piping for which a fluid transient is applicable.
Also, OPPD had proposed to reference footnote (d) in Service Level C of the new Load Combination table proposed for new footnote (e). However, that reference to footnote (d) has been removed to clarify that fluid transients must be considered, where applicable, as noted above. OPPDs Corrective Action Program will resolve the remaining references to footnote (d) in Appendix F, Table F-1.
Markup and re-typed (i.e. clean) USAR, Appendix F pages are attached. Please note that this change to USAR, Appendix F does not affect the proposed changes to USAR Section 1.2 or USAR Appendix G as provided in Reference 1.

NOTES:
(a)    These stress criteria are not applied to a piping run within which a pipe break is considered to have occurred.
(b)    Loading combinations 2 and 3, stress limits for vessels, are also used in evaluating the effects of local loads imposed on vessels and/or piping, with the symbol PM changed to PL.
(c)    The tabulated limits for piping are based on a minimum "shape factor". These limits are modified to incorporate the shape factor of the particular piping being analyzed.
(d)    These load cases and limits apply only to the Pressurizer relief valve piping and supports.
(e)    As an alternative to USAS B31.7, 1968, Class 1, 2, and 3, non-reactor coolant loop piping analysis may also be performed in accordance with ASME III, 1980 Edition (no Addenda). Material properties shall be from the original code of record (i.e., USAS B31.7, 1968). Associated stress limits shall be in accordance with ASME III, 1980 Edition (no Addenda) for Service Levels as shown below:
Load Combination Service Level A: Design Loading (Pressure, Weight, Other Mechanical Loadings, and Thermal where applicable)
Service Level B: Design Loading + Design Earthquake Service Level C: Normal Operating Loadings + (Maximum Hypothetical Earthquake + (Fluid Transient Loading) (g))
Service Level D: Normal Operating Loadings + (Maximum Hypothetical Earthquake + Pipe Rupture (g))
(f)    Support analysis will continue to be performed in accordance with the existing licensing basis (i.e., Seventh Edition, AISC, American Institute of Steel Construction).
(g)    Square-Root-Sum-of-the-Squares may be used to combine loads.
