'is to be received in confidence by the.NRC.

l (vi) The proprietary information sought to be withheld from public disclosure has substantial commercial value to Duke.

(a) It allows. Duke to reduce vendor and consultant j expenses associated with supporting the operation and licensing of nuclear' power plants.

5. Public disclosure of this information is likely to cause harm to Duke because it would allow competitors in the nuclear industry to benefit from the results of a significant development program without requiring commensurate expense or allowing Duke to recoup a portion of its expenditures or benefit from the sale of the i information.
