(Closed) Unresolved Item (341/78-10-05):
Internal audits performed by the L. K. Comstock Corporate office were in the format of an evaluation report.
The RIII inspector reviewed recent L. K. Comstock audits and determined them to be in an audit forrat.
(Closed) Noncompliance (341/78-10-01):
Measures not established to con-trol conduit fill requirements.
The RIII inspector reviewed Design Change Notice (DCN) No. 1034, Revision A.
The notice specified a numbering system and controls which would control the cited conduit fill requirements.
A letter, Control No. LKC-QC-371 dated September 25, 1978, from the L. K. Comstock QA Manager to Detroit Edison QA indicated training relative to DCN No. 1084.
L. K. Comstock Work Instruction No. 000-03-008 has been revised to reflect DCN No. 1084.

(0 pen) Noncompliance (341/78-10-02):
Nonseismic fire main pipe installed across redundant Class lE cable tray systems.
Design change Notice No.
1265 dated October 2, 1978, has been written to modify the fire main pipe over the cited trays to seismic qualifications.
The design procedure to prevent this type of situation from recurring has not been completed.
Letters, EF2-41985 and EF2-42119, indicate that the scope of the proced2rt is being developed.
The aforementioned actions are consistent with thcse described in DECO's response letter dated September 1, 1978, except fo-scheduled completion dates.
(Closed) Unresolved Item (341/78-10-03): Separation criteria for u'/ision 1 Cable No. 235625-1C being pulled into a Division 2 control panel.
Design Change Notice (DCN) No. 1222 dated October 2, 1978, has been written to specify the separation criteria for the above condition inside the panel.

(Closed) Followup Item (341/78-09-14)'
Design changes were not posted
.
on applicable documents as specified.
Daniel International Audit Findi Report (AFR) Ni). 78-05-35D had already identified this situation.
Durine this inspection, the RITI inspector verified AFR No. 78-05-35D had been properly closed out and the cited design changes had been pfbperly posted or incorporated.
(0 pen) Unresolved Item (341/78-09-15): Measures to control reinspection activities necessitated by design changes and performed by L. K. Comstock.
Measures have not been established.
However, Daniel Internation1 cor-respondence, DIC 8-6811 and DIC 8-7840, documents activities to develop the measures.
The licensee stated that the measures should be developed within four to six weeks.
(0 pen) Unresolved Item (341/78-09-16):
Measures to control reinspection activities necessitated by design changes and performed by General Electric Installation and Service Engineers, GEILSE.
The nucbor cf design changes affecting GEI&SE has increased substantially in the past six months. Therefore measures are being developed to control reinspection activities.
The measures should be developed within four to six weeks.
(Closed) Unresolved Item (341/78-13-01):
Seismic qualifications of spade lugs in General Electric supplied Class IE Panels.
The RIII inspector reviewed and discussed Audit Report EF2-44324 performed September 27 through 29, 1978.
The audit summary indicated that seismic test documentation for Combination Operating Panel No. H11-P602 was reviewed and found satisfactory.
The tests were performed using spade lugs.
Seismic reports, for the GE supplied cabinets mounted in the relay room and local racks and panels, were not available to the auditors during the audit period.
Therefore, the auditors identified the remaining seismic reports as an open iter to be evaluated during a followup audit.
