II. Restatement of Unresolved Item:
-It was found that several masonry-walls in the Reactor Building !
and the Emergency Cooling Tower had what appeared to be through ;
cracks at the boundary interface with reinforced concrete walls. 3
The licensee's construction detail drawing (6280-S-246, Rev. 5) d
specified concrete expansion anchor bolts to provide a. positive d
connection at this type of boundary. The inspector was unable to
- confirm the existence of positive connections through visual j
h observations or from the licensee's QC documentation. All of the l L noted crack locations were at wall boundaries where simply {
supported boundary conditions utilizing positive connections had I
been assumed in the reevaluation calculations. The postulated

' ,: [
omission of the specified anchor bolts coupled with an apparent .
l through crack.would invalidate the reevaluation. calculations and ) l: raises questions regarding the licensee's conclusion that the
walls are structurally adequate.
The licensee was requested to provide additional information
describing their. resolutions and a proposed schedule for actions.
This item is unresolved pending licensee's submittal and NRC l
review of the additional information described above (50-277/87- l
16-02 and 50-278/87-16-02). ]

Response to Unresolved Item:
<
PECo believes that the anchor bolts do exist, as detailed in the l
design drawings.- In order to resolve this item, PECO will chip
out the mortar joint at three of the walls inspected by.the NRC !
and confirm that the anchors exist. This work is scheduled to (
~begin October 1, 1987 and be completed by November 1, 1987.
