The inspector verified that the components, cables, raceways, junction boxes, penetrations and connections were as identified in the licensee's data for item 17 entitled, " Air manifold pilot solenoid valves".
The licensee in the 90 day documentation submittal listed items 1 and 2 of the above table as not being qualified and would be replaced with a qualified replacement component (solenoid valve).
The documentation package which identified the qualified component was in the licensee's review cycle.
The inspector did not have the replacement component documentation package for review, but the cabling, raceways, junction boxes and penetrations as listed in the 90 day data package was verified by the inspector while item 17 was being inspected.
The inspector reviewed the engineering data which was prepared by the licensee's engineering department which replaces the existing ASCO Model Number T8300C61U (Air operated valve - pilot solenoid valve)
with ASCO Three-Way Solenoid Valves Catalog No. 206-380-3-U.
The engineering data package consisted of the following requirement and documentation references.

Main Steam Isolation pneumatic Control Manifold Maintenance The air manifold pilot solenoid valves and the manifold for the Main Steam Isolation Valves A0-02-80A, 808, 80C and 80D ware removed for maintenance and part replacement as defined in Peach Bottom procedure M1.5 dated April 25, 1980.
Both the inboard and outboard components were changed during this outage.
An inspection of the MSIV pneumatic control manifolds revealed cracking at the base of the 1/16" wide x 1/8" deep wall on the "0" ring gr] oves.
(The referenced "0" ring grooves are around the manifold to cylin-:er parts).
The part manufacturer, Automatic Valve Corporation, has provided the licensee with a sketch No. AX495 for a recommended rework of the C5158-1 manifold blocks and a reference to " Installation Instructions l
for Model C5158, Revision "K" Manifold Assembly" and Step 13 Form No.
l D181-82676 for installation bubble tight test.
