They are intended to support review of the Diablo Canyon preventive maintenance and test intervals program for reactor trip breakers (Generic Letter 83-28, Item 4.2, Reactor Trip System Reliability).
One copy of HCAP-11312 (Proprietary) was previously transmitted in PGtErE letter DCL-88-193, dated August 1, 1988.
HCAP-11312, Rev.
1 contains information proprietary to Hestinghouse Electric Corporation.
Therefore, Enclosure 3 includes a
Hesti nghouse authorization letter (CAH-88-099), proprietary information notice; and accompanying affidavit signed by Hestinghouse, the owner of the information.
The affidavit sets forth the basis on which the information may be withheld from public disclosure by the Commission and addresses with specificity the considerations listed in paragraph (b)(4) of Section 2.790 of the Commission's regulations.
Accordingly, it is respectfully requested that the information which is proprietary to Hestinghouse be withheld from public disclosure in accordance with 10 CFR 2.790 of the Commission's regulations.
Correspondence with respect to the propri etary aspects of the Application for Hithholding or the supporting Hestinghouse Affidavit should reference CAH-88-099 and should be addressed to a~~~
