temporary attachments, d.
installation in accordanc with the drawings.

It was observed that the seismic restraint EFH-45S in the emergency

feedwater system did not conform to the dimensional requirements of the applicable Bergen-Paterson Pipe Support drawing No.1691-1.
The restraint had been installed with a 1/2" clearance on one side of items numbered 1 and 8 instead of a 1/4" both sides as required gg !
by the drawing. The licensee's engineering staff stated that the
~
restraints must meet the dimensional requirements of the drawing.

Nonconformino Cable Installation
'
}]
a.
The inspector found several vertical cable trays where the
_.
safety related cables had not been tied to the cable rungs as a
speci fied. The cables were instead tied to the outer side of
..Z sections of conduit which had been clamped to the sides of the JF t ray.
The cables were not, therefore, within the confines of 1::-
the trays.
This installation is not in accord with the 2~
constructor's Electrical Construction Procedure ECP-2, "Re-
. 2..
ceiving, Storing, Handling, and Installing Wire and Cable,"
~ " ~
Revision 8 Paragraph 4.12, which states, in part, "All cable

installed in cable trays shall be tied down to the tray
"'
rungs."
g._;;
Paragraph 4.12.3 of this procedure states, " Vertical cable
~-.
runs (2) inches in OD and smaller are to be tied down at
"
E intervals of 27 to 36 inches as required." This requirement llg had not been met inasmuch as spacing of the conduit to which
