I, BRENT R. SHELTON, being duly sworn, dispose and state the following:
1.
I am the Project Engineering Manager for Commonwealth Edison Company and have been delegated the function of reviewing the information described in paragraph 2 which is sought to be withheld and have been authorized to apply for its withholding.
2.
The information sought to be withheld is the document entitled "LaSalle County 1 In-Plant S/RV Test Initial Evaluation Report" dated February 1983.
3.
In det.lgnating material as proprietary, Commonwealth Edison Company utilizes the definition of proprietary information and trade secrets set forth in the American Law Institute's Restatement Of Torts, Section 757.
This definition provides:
"A trade secret may consist of any formula, pattern, device or compilation of information which is used in one's business and which gives him an opportunity to obtain an advantage over competitors who do not know or use it.
A substantial element of secrecy must exist, so that, except by the use of improper means, there would be difficulty in acquiring information.
Some factors to be considered in determining whether given information is one's trade secret are:
(1) the extent to which the information is known outside of his business; (2) the extent to which it is known by employees and others involved in his business; (3) the extent of measures taken by him to guard the secrecy of the information; (4) the value of the information to him and to his competitors; (5) the amount of effort or money expended by him in developing the information; (6) the ease or difficulty with which the inforn,ation could be properly acquired or duplicated by others."
4.
The designated document constitutes information and data which demonstrate the adequacy of existing design basis hydrodynamic loads resulting from safety / relief valve actuation.
This data was acquired during testing at LaSalle County Station.
Test results apply to any other user of the load mitigating T-quencher device located on the end of the S/RV discharge line.
Because duplication of such information would entail significant expenditure, public disclosure of the information would deny Commonwealth Edison its proprietary interest.
Although other utilities shared the cost of the temperature portion of the test, the loads portion which is presented in the designated document was funded solely by Commonwealth Edison.
Ownership, therefore is that of Commonwealth Edison.
The test data has been held in confidence and is not otherwise available.
5.
Initial approval of proprietary treatment of a document is made by the Project Engineering personnel most acquainted with the value and sensitivity of the information in relation to industry knowledge.

< 6.
The document mentioned in paragraph 2 above has been evaluated in accordance with the above criteria and practices and has been found to contain information which is proprietary and which is customarily held in confidence by Commonwealth Edison Company.
BRENT R. SHELTON, being duly sworn, disposes and says that he has read the foregoing affidavit and the matters stated therein are true and correct to the best of his knowledge, information and belief.
Executed at Chicago, Illinois, this 7th day of March 1983, h
