Subject:
B-SAR-205 Transmittal of Proprietary Portion of Amendment 13 Re fe ren ce : Letter, J. H. Taylor to R. S.
- Boyd, "B-SAR-205 - Transmittal of Apoendix 13,"
April 18, 1977
Dear Mr. Boyd:
The Babecek and Wilcox Company herewith submits 25 copies of proprietary Table 221.54-6. Figure 221.54-6 demonstrates local measurements of core 4 inlet flow distribution acquired during Vessel Model Flow Teating. This information was obtained at B&W expense and, if released for public disclosure, could result in a decrease in expenditures, time, and resources by competitors in designing and testing their core support assembfy hardware. B&W feels that such advantages to competitors could result by (1) comparing their flow distribution information to the attached and thus suggest core support assembly design changes, and (2) demon-strating the degree of symmetry as well as radial flow gradients which would lessen instrumentation requirements for future competitor Vessel Model Flow Testing. Also attached are the standard forms used by B&W in supporting requests that proprietary information be withheld fron public disclosure pursuant to the r =quirements of 10 CFR 2.790. gr' truly yours, /* Yl 0 J.7 ) t ( 7 Taylor,l / ames H.
