The inspector also reviewed licensee action on previously identified items and performed plant inspection tours.
The inspection involved 117 inspector hours including 2 off-shift hours by the resident inspector.
Results:
No violations were identified.

P
embed plates and violates a P301J criteria for a 1" separation between the support member and the edge of the embed plate to eliminate prying effects.
After the identification of the non-conforming condition by the inspector, NKD report IG-299 was issued.
As the 1"-criteria was incorporated into specification P301J on August 7, 1982.
and support BZ-19NM-1 was inspected on August 3, 1982, the inspector has an open concern as to how pipe supports inspected prior to August 7, 1982 can be assured to be structurally adequate as the 1" criteria was not an inspection attribute.

Meld Rod Material Control The inspector identified that rod storage ovens 18 and 19 at Stone
Mebster rod station 3 had suffered a drop in temperature to below 100oF during a re-wiring of the rod station.
Specification 7201,
"Field Storage, Handling and Issuance of Melding and Brazing Materials,"
requires that the ovens remain at 300oF k 50oF for mild steel electrodes and 200o t 50oF for all other electrodes.
The non-conforming oven temperature was not reported to gC nor was the rod material rebaked or segregated in accordance with specification 7201.
Nonconformance and Deviation report 4954 has been issued, to document the occurrence.
All welds have been identified for which affected rod material was utilized and the remainder of the rod has been scrapped.
This item will remain unresolved pending-disposition of NOD 4954 and.future.inspection to.
assure that adequate corrective action has been instituted to preclude recurrence of this problem.

Cable and Electrical E ui ment Installation a.
The inspector reviewed the following documents for requirements pertaining to electrical cable installation:
FSAR IEEE336 Specification E061A, "Electrical Installation" guality Assurance Directive gAD 10.18 guality Standard gS 10.52 Inspection Plan N20E061A FA025 I
The installation of the -following cables was observed to be.performed...
in accordance with the applicable criteria:
Cable ticket 2CCPNYK003
~
'
Cable ticket 2ICSNGC025 Cable ticket 2ICSNGC006
'he inspector has no further questions regarding cable installations.
b.
The standby battery installations at elevation 261 in the control building were examined by the inspector.
Stone 8 Webster drawing EE-27C-9 provides the battery room arrangement and the Gould battery manual provides specific installation requirements..
Tlie-inspector.
noted that some inter-cell spaces were provided with foam spacers while others were not.
He reviewed Gould prints which specify that-all inter-cell spaces are to have the foam inserted.
Requisition 202l84 was reviewed to document'that additional foam spacers are on order to complete the installation.
The Gould manual (file 1.520-217-007B)
contains a precaution thatbatteries shipped in a wet and charged condition should not be stored for longer than six months without re-charging.
As the associated battery chargers were not installed at the six month date, the inspector insured that Stone 8 Webster preventive maintenance had contacted the battery supplier for guidance on extending the storage limit.
The inspector examined the anchorage details for a Gould MCC walk-in enclosure (file 0001540211169C)
against the as-welded condition.
The required weld pattern for locations of shipping split functions was unclear.
The licensee has requested Brown-Boveri (via transmittal No. TF-2358) to revise a note allowing a 3" weld to be divided equally to either side of the shipping )oint.
In regards to the installations of the batteries and enclosures, the inspector has no further questions.
c.
The inspector noted several floor to ceiling cable tray supports within the Division I electrical tunnel between the'ontrol and Reactor Building.
The supports were rigidly attached at both connection. points.
Within FSAR Section'.10.3A, the seismic analysis of tray support members is performed assuming rigid attachments to the structure.
However, the inspector questions whether differential slab motions were considered such that these unique floor to ceiling supports would not be overstressed during a seismic event.
Pending the licensee providing the requested calculations for supports:
CP-86 and FP-87 (tray 2TX005G)
CP-78 (tray 2TX006G)
CP-12 (tray 2TX006G)
this issue will remain unresolved.
