Followup On Previously Identified Items (Units 1 and 2)
(Closed) Open Items 368/8627-04 and 313/8626-01:
backlog.
The primary concern of this item was the existence of many temporary
modifications (TMs) dating as far back as 1980.
The temporary
i
modification log books of both units were reviewed.
Progress was noted
i
in reducing the number of TMs.
The NRC inspectors discussed this item
with the licensee and reviewed the program implemented to close out old
TMs.
Since the start of the TM reduction effort, the number of TMs
1
(6 months old or older) has been reduced from 51 to 15 in Unit 1 and from
'
80 to 18 in Unit 2.
The NRC inspectors also reviewed Procedure 1000.28,
!
" Temporary Modification Control," Revision 7, dated January 1, 1987, and
l
determined that it appeared adequate to ensure that TMs are properly
reviewed and approved prior to installation and that they will not remain
l
installed without periodic review and justification.
Based on these
reviews the NRC inspectors concluded that the licensee's efforts to

(0 pen) Unresolved Item 313/8601-06:
Failure to assure that instructions
and drawings'were appropriate to the circumstances.
Thisite'mwasdisdussedinNRCInspectionReport.50-313/87-13.
Violation 313/86-01 (II.0.1.a-d) was ret ^erenced.
Due to an. oversight,
this reference was incomplete.
It should have included Items II.D.2 and-
';
II.D.3 as corrective action on these examples was also verified during
-
Lthe~same inspection.~ ; This item remains open due to concern over
erroneous valve. position and locked status information.'being shown ori
piping and instrumentation diagrams.
No violations or deviations were identified.

'
including potential- fire hazards, fluid leaks, and excessive vibration.
The NRC inspectors also observed plant housekeepingLand cleanliness
. conditions during the tours.
The NRC inspectors walked down the accessible portiens of the emergency
diesel generator auxiliary systems for both units using
Procedures 1104.36, Attachments 1 and 2; 2104.36, Attachments A and B;
and Drawings M-217 and M-2217 to. verify operability.
Some minor
deficiencies were noted. These did not affect system operability and
were promptly resolved by the licensee.
'
During a routine tour of the "A" decay heat vault in the Unit 1 auxiliary
building, the NRC inspectors noted the following problems:
'Large' diameter hoses and fittings had been placed on top of the
.
floor mounted room cooler (VUC-1A).
Apparently they had been left
there following the flushing of the service water system during the
,
last refueling outage.
The fittings and hoses were promptly removed
i
after the licensee was informed.
The NRC inspectors expressed a
concern to the licensee that this item indicated a need for
,
'
improvement in work closeout.

Seismic. Support DH-60 was not in conformance with the configuration
.
depicted in Design Drawing HCB-2-DH60, Revision 2, dated August 27,
1980.
Three of four anchor bolts in one of the support baseplates
< , ,
were not torqued as evidenced by no contact between the nuts and the
"
"

i
<
baseplate.
This support is next to Valve CV-1405 in the 14-inch
!
.
H
pipe which supplies Decay Heat Pump P34A and Spray. Pump P35A from
.
the reactor building sump.
This deficiency is similar to the

violation identified in the Unit 2 supply line to the Train "A"
i
'
engineered safety features pumps as documented.in NRC Inspection
l
Report 50-368/87-08.
After notifying the licensee of the deficiency
the .three bolts were properly torqued, thus returning the support to
its design configuration.
This deficiency is an apparent violation
(313/8715-01). .' Subsequently, the licensee informed the NRC
inspectors that operability evaluations for these supports found
that system operability had not been affected.
,
These reviews and observations were done to verify that facility
operations were being conducted safely and were in conformance with the
requirements established under Technical Specifications, 10 CFR, and
i
administrative procedures.
4.
Monthly Maintenance Observation (Units 1 and 2)
l
Station maintenance activities of safety-related systems and components
listed below were observed / reviewed to ascertain that they were conducted
in accordance with approved procedures, Regulatory Guides, and industry-
codes or standards; and in conformance with Technical Specifications.
lThe following items were considered during this review:
the limiting
j
conditions for operation were met while components or systems were
removed from service, approvals were obtained prior to initiating the
work, activities were accomplished using approved procedures.and were
inspected as applicable, functional testing and/or calibrations were
'
performed prior to returning components or systems to service, quality
j
control records were maintained, activities were accomplished by
qualified personnel, parts and materials used were properly certified,
radiological controls were implemented, and fire prevention controls were
implemented.
Work requests were reviewed to determine status of outstanding jobs and
to ensure that priority is' assigned to safety-related equipment
maintenance which may affect system performance.
The following maintenance activities were observed / reviewed:
Installation of Battery Charger 2D31 per DCP 86-2106 (Job
.
Order 729325)

Monthly Surveillance Observation (Units 1 and 2)
The NRC inspectors observed the Technical Specification required
surveillance testing on Unit 1 Decay Heat Removal Pump P34B
(Procedure 1104.04) and verified that testing was performed in accordance
with adequate procedures, test instrumentation was calibrated, limiting
conditions for operation were met, removal and restoration of the
affected components were accomplished, test results conformed with
Technical Specifications and procedure requirements, test results were
reviewed by personnel other than the individual directing the test, and
any deficiencies identified during the testing were properly reviewed and
resolved by appropriate management personnel.
The NRC inspectors also witnessed portions of the following test
activities:
Emergency diesel generator operability test (Procedure 2104.36,
.
Supplement 2)
Post installation performance test of Makeup Pump P36B
.
(Procedure 1409.061)
