Inspection Purcose
A management interview was held at the start of the inspection on
September 13, 1978, to explain that the purpose of the inspeEt' ion
was to review the actions taken by the licensee in regard to Inspec-
tion and Enforcement Circular 78-08, transmitted to the licensee
'
on May 31, 1978.
3.
Insoection Scoce
Thc areas reviewed during this inspection encompassed those items
listed in IEC 78-08, involving problems that have been identified
in ensuring environmental qualification of safety-related electrical
components. The following were addressed:
a.
whether a specific licensee individual has been assigned
responsibility for reviewing identified problems and docu-
mentation referenced in IEC 78-08;
b.
whether a comparison has been made between the plant specific
circumstances at Indian Point, Unit 2 and problems identified
by IEC 78-08;
c.
what actions have been taken by the licensee in regard to the
subject reviews, the status of any corrective actions planned
or taken, and the schedule for finishing the -review of any
areas not yet complete;
d.
a sampling review of documentation which supports the environ-
mental qualification of electrical components, including
l
electrical connectors, containment electrical penetrations,
'
l
terminal blocks, cables and cable splices, transmitters and
valves.

Findings
The following unresolved items were identified during the inspection
l
of the licensee review of IEC 78-08 and require further action by
l
the licensee.
!
a.
Cable Solices
1:
The licensee has~ established that during construction, splices
in safety-related components and penetrations were to be accom-
plished to the " Splicing and Terminating Instructions," Draw-
ing 9321-LL 3011 which specifies the type of seal to be in-
l
stalled. Environmental qualification of this type of seal
+
and an in-plant verification of installed splices has not been
'
completed.
(247/78-30-01)
1
b.
Stem-Mounted Limit Switches
The licensee identified in a response to IE Bulletin 78-04,
(March 23,1978), the future replacement of a number of limit
switches. A modified operating procedure is currently in
,
effect to monitor limit switch positions. (247/78-30-04)
c.
Motor Ocerated Valves
The licensee is reviewing the WCAP 7410-L for verification
of environmental qualification of safety-related motor oper-
ated valves.
(247/78-30-02)
d.
Terminal Blocks
The licensee has not identified documentation for the environ-
,
mental qualification of terminal blocks with the associated
terminal boxes and cable connections for safety-related
equipment.

The above unresolved items require the following:
Correlatior of actual installed material vs. documented generic
-
test data.
Review of the quality assurance records for the environmental
-
tests.
Further review by the licensee's engineering staff as to the
-
adequacy of the environmental testing for the existing equip-
ment installed in safety-related systems.
The licensee expects to complete the review by October 30, 1978.
This review will include visual verification of the existing equip-
ment on a sampling basis.
These items will be reviewed ca a subsequent inspection.
6.
Unresolved Items
,
Unresolved items are those items for which more information is
required to determine if the items are Acceptable or Items of
Noncompliance. Unresolved items are contained in Detail 5 of
'
this report.
7.
