A LRT of THE PENN CENTRAL COAPORATION December 19, 1983 AFFIDAVIT North Anna Power Station Spent Fuel Storage Rack Design Calculations We the undersigned do hereby attest that the attached twelve (12) pages of weld stress calculations prepared by NES for the North Anna Power Station Spent Fuel Storage Rack
- Project, contain confidential design information and analysis techniques which should not be publicly disclosed.
It is an NES policy to maintain the confidentiality of design documents due to the detailed design information and analysis techniques contained therein.
In the case of spent fuel rack designs, it is essential that these documents be prevented from entering the public domain because spent fuel rack contracts are competitively awarded.
If the detailed characteristics of NES' design and analysis techniques were made public, it would adversely effect our competitive position within the industry.
NES is consistent in the application of this policy regarding design documents for fuel rack projects. Most recently, a similar affidavit was utilized to prevent Trojan Spent Fuel Storage Rack design documents from entering the public domain.
Please note that NES has no objection to allowing the calculations to undergo closed examination by cognizant representat es of the NRC for the purposes of licensing approval.
