ABB Combustion Engineering Report CEN-614, " Safety Evaluation of the Potential for and the Consequence of Reactor Vessel Head Penetration Alloy 600 00-Initiated Nozzle Cracking," December 1993.
2.
B&W Report BAW-10190, Rev.1, " External Circumferential Crack Growth Analysis for B&W Design Reactor Vessel Head Control Rod Drive Mechanism Nozzles," January 1994.
3.
Westinghouse Report WCAP-13525 Appendix 1, Addendum 1, "RV Closure Head Penetration Alloy 600 PWSCC (Phase 2)," December 1993
[ Proprietary).

Mr. Alex Marion March 14,1994 The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use 7
by any of Westinghouse's competitors without license from Westinghouse constitutes a competitive economic advantage over other companies.
Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing a similar product.
We have reviewed Mr. Sepp's affidavit and the material based on the requirements and criteria of 10 CFR 2.790 and, on the basis of Westinghouse's statements, have determined that the submitted information sought to be withheld contains trade secrets or proprietary commercial information.
Therefore, the version of the submitted information marked as proprietary will be withheld from public disclosure pursuant to 10 CFR 2.790(b)(5) and Section 103(b) of the Atomic Energy Act of 1954, as amended.
Withholding from public inspection shall not affect the right, if any, of persons properly and directly concerned to inspect the documents.
If the need arises, we may send copies of this information to our consultants working in this area. We will, of course, ensure that the consultants have signed the appropriate agreements for handling proprietary information.
If the basis for withholding this information from public inspection should change in the future such that the information could then be made available for public inspection, you should promptly notify the U.S. Nuclear Regulatory Comission (NRC).
You should also understand that the NRC may have cause to review this determination in the future, such as, if the scope of a Freedom of Information Act request includes your information.
In all review situations, if the NRC makes a determination adverse to the above, you will be notified in advance of any public disclosure.
Sincerely, M M GL.
