Dear Mr. Denton:
In Reference (b), Commonwealth Edison Company submitted a revised version of Zion's inservice volve testing program.
At the suggestion of Mr.
V.
Nerses of your staff, additional revisions are row being subnitted.
Attachment A to this letter explains the changes that have been made.
Attachment B and C contain complete sets of pages 47 through 83 for the Inservice Valve Test Programs f or Zion 1 and Zion 2,
respectively.
These pages incorporate the changes explained in Attachment A and were retyped to improve clarity.
It was also requested that we address the safety significance and functional testing of the Isolation Valve Seal Water (IVSW) system.
The substitution of IVSW system testing for the requireo leak testing of numerous containment isolation valves nad previously been submitted as a code relief request.
It was agreed that the IVSW system should be classified as an ASME system for the purposes of ASME Section XI.
Based on the guidelines of Reg. Guide 1.26, paragraph C.2.d, the IVSW system will be designated as ASME Class 3.
Please address any questions that you might have concerning this matter to this office.
