Review of Preoperational Testing Reruits The inspector reviewed the documentation packages for the completed Unit 2 preoperational tests listed below and made the following comments. Licensee representatives stated that appropriate action will be taken to resolve each ite ?
.
O a.
W12.2A Annunciator Equipment checkout, test completed 6/5/80.
(1) Page 62 states that annunciator 2-XA-55-63/30 ha- =. n apparent anomalous wiring condition and that this matter ne r. solution by TVA Engineering Design. (IFI 323/80-27-01).
(2) 'One page, Appendix F Temporary Condition Log, was missing from the test record.
Indications are that no temporary conditions were required during this test. (I F1 323/80-27-02).
The test record states that annunciator panel 2-M-21 needs to be
'
ventilated anc dust protected.
Licensee representatives stated that an engineering change notice (ECN) has been issued to make the required modifications. (IFI 328/20-27-03)
-(4) The test record copy reviewed by the inspector had numerous missing and duplicate pages. Licensea representa:ives stated that they will c.nfirm that copies distributed for reviu are accurate.
(IFI 328/20-27-0?)
b.
TVA - 21A Containment Spray System (1) Step 5.1.21 contains a typographical error in a valve number yet
.was signed off as completed. Licensee representatives stated that a corrective memo will be added to the test record. (IFI 328/30-27-05)
(2) Test records show that the spray header piping was intentional 1" left water filled for an indeterminant period of time follcoing hydrostatic testing.
Licensee representatives stated they will investigate the ' potential for corrosion damage of this piping.
. (-IFI 323/80-2C-06)
c.
TVA - 8 Post-LOCA Hydrogen Recombiner, ' est completed 11/11/80 (1) A hot w:re anemometer used for air flow rate measurement exceeded its calibration due date during the test period.
The instrument was subsequantly checked and:found to be out of calibration. The test director stated-in the test package that the instrument was
reading low which would imply that. test results were still satis-
,
-
. factory After re/iewing the calibration data, the inspector
,
!
concluded. the opposite i.e.
that the instrument had been reading high ard that the apparent error was sufficient to possibly render the test.results ' unacceptable. 'After researching the matter,
,
licensee representatives. stated that during test results review, TVA engineering design had also concluded that the test results were unacceptable and that the test will be repeated. (IFI 328/80-27-07)

Licensee representatives statec tna; they will confirm tna ccpies distributed for review are accurate. (IFI 323/53-27-03)
(3) The inspector noted that t e 22-3 recc=biner wcs initially en h
10/23/80 and after correction of wiring errors retested on
!,
10/27/80. Data sheet 5.1 reflects a large difference between :ne
!
!
tro tests in the maximum power consumption of the recembiner.
Licensee representatives stated they sill investigate the cause.
(IFI 328/80-27-09)
No viclations or deviations were -identified in this area.
5.
Plant Tcur Tne inspector toured various portions of both units. Particular attention was given to unit 2 plant system status.
Major portions of tne Resicuai Heat Removal, Safety Injection, Chemical anc Volume Control System, and Contair. ment' Spray systans were examined c ccnfirm that piping c;nfiguraticn j
is accurately reflected by the piant drawings.
(
l The inspector observed the folicwing apparent equipment inadequacies and
!
pointed cut these items to plant management. Licensee representatives stated
that the items will be reviewed and appropriate action taken a.
Containment Spray systera motor operated valve 2-FCV-72-2'. was observed
,
to have only two of the four required bolts present to a. tach the motor
!
operator to the valve body.
Electrical conduits were not properly
[
attached to the motor operator.
{
.
.
t b.
ine eiectrical box JB758 containing local control switches for motor
!
operated valves 2 HS-72-228 and 238 has attached an outdated construc-tien tag for valve 23 and.a nonconformance tag dated 7/11/79.
f c.
The 2B-8 RHR pump seal appears to be leaking water.
d.
The Unit 2 RHR system contains numerous' construction tags from a ccid hydro test conducted during 10/80. The system has been transferred to
,
Power Production and the tags should have been cleared at transfer-I according to the preoperational testing personnel.
[
[
e.
Valve 62-3468, the vent valve to flow transmitter 62-93, appears to
ha-a water leak in a weld.
[
~
f f.
. Charging pump 2B-3 has been disassembled for repairs.
The system
,
piping discenr.ected frca the pump. was observed to be cpen and a
unprotected fro't entry of foreign material.

.
inadequacies do not acoear on the Unit 2 Outstanding Work Items List (CWIL)
[
'
or on the list of incomplete work iter-resulting from system wa.k down
during turnover from construction to pcwer proouction.
Licensee represen-l l
tatives stated that many of these type of items will be documented by
'
!
Maintenance Request (MR) when identified by plant personnel and that the MR
{
list will be merged with the OWIL list just prior to hot functional testing.
j This matter will be pursued further during a future inspection.
