Dear Mr. Carolan:
SUBJECT:
WITHHOLDING FROM PUBLIC DISCLOSURE - SETPOINT METHODOLOGY PROGRAM DOCUMENTS J~
Your letters, dated September 24, 1985, and March 1, 1985, transmitted Interim ~
Reports on Setpoint Methodology for General Electric Supplied Protection System Instrumentation. Our letter, dated August 13, 1985, requested an application
. for withholding from public disclosure pursuant to 10 CFR 2.790 and a General
. Electric Company affidavit, which were received by your. letter, dated September 30, 1985.
You stated that the submitted infomation should be considered exempt from man-datory public disclosure for the following reasons:
1.
The information submitted has been held in confidence by General Electric and access within the company has been limited on a "need to know basis" and such documents are clearly identified as propri ~
~
etary. No public disclosure of the information has been made
, _ = -
pursuant to regulatory provisions of proprietary agreements which provide for maintenance of the infomation in confidence.
- 2.
The documents submitted consist of detailed responses to specific topics of interest to the NRC. The development and integration of this infomation into a consistent and technically viable method-ology.m' kes it possible to detemine setpoints which provide a
increased plant operating flexibility while at the same time satisfying a number of potentially conflicting operational and licensing requirements. The integrated approach contained in the documents represents combined contribution of over 30 individuals and over 10 man-years of effort. The release of the integrated approach supported by these documents would pemit competitors to apply the resulting calculation techniques to virtually any reactor plant design and substantially reduce General ' Electric profit making opportunities. Release of the infomati.on'to the 0

public would enable General Electric competitors to duplicate design techniques developed by General Electric without commen--
surate time, money, labor and experience.
[
We have reviewed your application and the material based on the' requirements and criteria of 10 CFR 2.790 and on the basis of statements provided by you.
and General Electric Company have determined that the submitted information sought to be withheld contains trade secrets or proprietary commercial information.
We have detemined that the following documents marked as proprietary, should 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:
(a) Proposed General Electric Instrument Setpoint Methodology, May 1985 (b) Proposed General Electric Instrument Accuracy and Drift Validation 1
Methodology, May 1985 w.
(c) General Electric Instrument Setpoint Methodology (Preliminary),
V. Handa, E. C. Eckert, December 1983 (d) Response to NRC Item 5.1, Environmental Effects, October 1, 1984 (e) Response to NRC Items 5.2, 5.3, and 5.4, Calculation of Instrument Inaccuracies and Drift Values, October 1,1984 l-(f) Response to NRC Item S.4b, APRM Validation Calculation, October 1, 1984 (g) Response to NRC item 5.6, Statistical Methods, September 6, 1984 (h) Response to NRC Item 5.7, Computer Code Modeling Conservatisms,

-(i) Response to NRC Item 5.8, Safety Limits, August 31, 1984

We therefore approve your request for withholding pursuant to 10 CFR 2.790 and are withholding the above described documents as proprietary.
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 infomation to our consultants working in this area. We will, of course, insure that the consultants have j
signed the appropriate agreements for handling proprietary infomation.

If the basis for withholding this infomation from public inspecthn should

change in the future such that the information could then be made available for public inspection, you should promptly notify the 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 needs additional in-formation from you or makes a determination adverse to the above, you will be 1
notified in advance of any public disclosure.
