Ref.: 2 Letter, Thomas H. Essig to H. D. Curet " Acceptance for Referencing of SPC Licensing Topical Report ANF-1125(P), Supplement 1 Appendix E, 'ANFB Critical Power Correlation Determination of Atrium-9B Additive Constant Uncertainties' (TAC No. MA2437), September 23,1998 i
On November 18,1998, Siemens Power Corporation (SPC) transmitted a letter (Reference 1) .
to the NRC requesting NRC's concurrence with SPC's understanding of the safety evaluation l report (SER) for SPC topical report ANF-1125, Supplement 1, Appendix E,"ANFB Critical Power Correlation Determination of Atrium-9B Additive Constant Uncertainties". In the letter, you requested the following points be clarified:
. NRC's concurrence with the definition of the maximum design limit in order to avoid any future misunderstanding regarding the application of )D the limit. (The discussion of the definition for maximum design limit is provided in Attachment A of your letter dated November 18,1998.)
. NRC's concurrence with SPC's understanding that safety limit g'y calculations using an ANFB additive constant uncertainties (ACU) value &
of 0.029 continue to be acceptable for Atrium-9B fuel.
The NRC staff finds that SPC's understanding of the above clarifications correct. Please note that in addition to the SER for the Reference 2 topical report, this letter and the Reference 1 letter dated November 18,1998 should be placed in the approved version of the topical report, ANF-1125, Supplement 1 Appendix E,"ANFB Critical Power Correlation Determination of Atrium-98 Additive Constant Uncertainties". 4 9812010009 981124 f,W 3 3 PDR TOPRP EMVEXXN u,, C,m PDR ] c,%
