Additionally, they shall determine how long the~ equipment may be'
out of service.
Granting of such permission shall be
documented.
Equipment that is environmentally qualified should be identified
as such prior to maintenance and sufficient control should exist
to ensure it is returned to that status upon reassembly.
When testing of redundant components or systems is required by
TS or 10 CFR 50, such testing shall be documented.
The status of equipment and systems will be clearly identified.

During the above examination the inspectnr noted an apparently
abandoned uncompleted support located directly above safety
injection swing check valve 1-1204-263-3 IN (IV501204-241-02) .
.
The partially completed support included a length of 4x4 Tube
Steel which had been machine cut at an angle, and partially
welded to an embed such that the other end was directly over the
valve and perpendicular to the longitudinal axis of the piping
involved.
The support appeared to infringe on the hot pipe
seismic separation clearances required to be verified during
as-built and construction turnover inspections.
The partially
completed weld was unp(ainted and had been in place long enough
for moderate rusting
in an enclosed pumphouse).
During the
time of this inspection, cognizant licensee personnel were
unable to properly identify or explain whether this item was an
unremoved construction aid, an uncompleted support which was
"
necessary and not shown on design drawings, or miscellaneous
steel deemed unnecessary but properly left in place.
The'
inspector informed cognizant licensee personnel that NRC concern
on this matter would be identified as Unresolved item
424/88-05-01; 425/88-04-01, Abandoned Pipe Support for Safety
Injection Piping.

Licensee Identified Items (92700)
Prior to the inspection, the licensee identified the following items under
a.
(Closed) Item 425/CDR 85-77 TDI Diesel Generator Crankshaft Oil Plugs
On April 24, 1985, the licensee notified Region II of a 50.55(e) item
concerning potential failure of TDI diesel generator crankshaft oil
plugs.
Corrective action required replacement of 22 gauge oil plugs
with new plugs from 16 gauge material.
The final report was submitted on May 23, 1985.
The final report has
been reviewed and determined to be acceptable by Region II.
The
inspector held discussions with responsible licensee representatives
and reviewed supporting documents to verify that corrective actions
