Dear Dr. Murley:
A meeting was held between Commonwealth Edison and members of your staff on May 2, 1989, in Rockville, Maryland to discuss the Robert L. Cloud Associates non-lineer piping analyses thet would be used to justify removal of snubbers and pipe supports at Byron and Braidwood Stations. This letter and the attachments provide the formal submittal to satisfy the requirements of the Standand Review Plan Section 3.9.1 titled "Special Topics for Mechenical Components".
Part 11.2 delineates the specific requirements for computer programs to demonstrate their applicability and validity.
Attachments 1 and 2 to this letter provide the required information in the prescribed format.
Commonwealth Edison requests review and approval of the analyses by February 1, 1990, to permit modifications on Byron Unit 2 during the September 1990 refueling outage.
Please direct any questions on this matter to this office.
Very truly yours, st&d i
R.
