2.
Storage Battery Cells in Contact with Racks
The inspector examined the storage battery installation and found that
several of the scorage cells were in direct contact with the uninsulated
metal side rails of the battery support racks.
This was contrary to
the constructor's site procedure ECP4.2, Paragraph 5.2.1, which states
.
" Cells should not touch each other nor should any cell touch metal
sup;2rts of the rack."
The licensee's representatives later agreed
that the installation drawings required plastic insulation strips on
the side rails in addition to the bottes rails.
-
The f ailure to provide the insulating strips was a vio.lation of
Criterion V,10 CFR 50, Appendix B, and the licensee's FSAR, Paragraph
17.1.5.4.

lleating Reinforcine Steel to Unknown Temperaturcq
The inspector found a large nudber of No. 18 reinforcing steel bars
in the containment structure being heated with an oxy-acetylene torch
preparatory to scratchbrush cleaning.
The =cchanics adnitted that
they should have been using Tempilstiks to indicate the rebar temperature.
-
When this work location was rechecked by the inspector later in the day,
i
Tempilstiks were being used.
The constructor'c procedure QC-1-2, Appendix B, Revision 5, July 13,
1973 limits the preheating temperature of rebar to 212-300'F prior to
scratchbrushing.
This is a violation of Criterion V,
i
,'
4.
Drawing Control
The inspector randomly selected 43 drawings on field stick files.
The
selection included electrical, piping, and structural drawings.
The
revision nu=ber of each of the 43 drawings was compared to the latest
.
revision nu=ber listed in the Engineering office card file.
Four of the
43 drawings (9.3%) on the stick files were found to be out of date.
This is a violation of Criterion VI of 10 CFR 50, Appendix B.
5.
Control of Weld Filler Material
!
In a previous inspection, a violation in weld filler material control
was identified by the inspector. The licensee has instituted corrective
'
action which was examined by the inspector, including re-instruction
of issue crib attendants, nu= bering of all electrode containers, increased
efforts on controlling electrode stubs.
The inspector examined the
corrective action, and audited field locations for the eff ectiveness
of the control =easures, and no deficiencies were identified.
