Letter logge.d TXX 90342, dated September 17, 1990, fr w W. J. Cahill, Jr. to the NRC.
Gentlemen:
The TV Electric reload analysis program was discussed with the NRC staf f in December, 1988, and again in July, 1990.
Following the July discussions, the schedule for submittal of the TV Electric topical reports was provided in the referenced letter.
Consistent with that schedule, attached for your review and approval is RXE 90 006 P. the Power Distribution Control Analysis and Overtemperature N 16 and Overpower N 16 Trip Setpoint Hethodology report.
The analyses presented in this report were referred to in the referenced letter as
" Axial Power Shape and Sutpoint Methodology." The non proprietary version of this report, RXE-90-006 NP, is also enclosed for your use.
RXE 90 006 P presents the methodology which will be utilized in support of reload design licensing, and operation of CPSES Units 1 and 2.
The design bases for the calculation of the Overpower N 10 and Overtemperature N 16 trip setpoints, including the treatment of the core power distribution ef fects and trip channel uncertaintles, are provided, The axial power distributions required for the development of the overpower and overtemperature trip setpoints are based on methodology developed and emplayed by Advanced Nuclear Fuels (ANF).
In addition. TV Electric has adopted the principal attributes of the approved MiF methodology for powar distribution control analysis in support of normal operation.
Approval of the enclosed report, along with approvals of those previously
)
submitted and those yet to be submitted, are required to allow TV Electric to itcense cycle 3 operation (scheduled to begin in September, 1992), without recourse to a nuclear fuel vendor. TV Electric requests that the NRC review and approve the enclosed report by November, 1991.

I am f ami!!ar with the TU Electric Company topical report RXE 90-006 P ontitled "P.) wor Distilbution Control Analysis and Overtemperaturo N 16 and Ovorpower N 16 Trip 5 otpoint Methodology," referred to as " Document." Information contained in this Document has bton classified by ANF as propriotary in accordanco with policios establishod by ANF for th( con'rol and p'otection.nf information.

4.
Tho Document has boon mado available to the U.S. Nuclear Regulatory Commission in confidenco, with the request that the information containod in the Document will not bo disclosed or divulgod.

- 5. The Document contains information which is vital to a competitivo advantago of ANF and would bo helpful to competitors of ANF when competing with ANF.
- 6. Tho information contained in the Document is considered to bo propriotary by ANF because it reveals cortain distinguishing aspects of ANF liconsing methodology which securo competitivo advantago to ANF for fuel design optimization and marketability, and includes information utlitzed by ANF in its business which affords ANF an opportunity to obtain a competitivo advantage over its competitors who do not or may not know or uso the information contained in the Document.
7.
Tho disclosuro of the propriotary information contained !n the Document to a compoiltor would permit the competitor to reduco its expondituto of monoy and manpower and to improve its competitivo position by giving it valuable insights into ANF licensing methodology and would result in substantial harm to the competitivo position of ANF.
