Licensee Action on Previous Inspection Findings (Closed) Noncompliance (50-329/81-11-02; 50-330/81-11-02)
!
a.
Bechtel procedure FPE 4.000, Revision 3, did not address:
(1) coiling of cables, (2) protection from jacket damage
'
during coiling of cables, (3) minimum bend radius when cables
are coiled. The inspectors identified Class IE cables 2BQ403N, 2BB2430G, 2BB2431N and 2BB2430N that had jacket damage and minimum bend radius was exceeded for Class 1E cables 2AB6304D and IBD2001AA. Also, Class IE coiled cable IBG020G was being
.
supported with small gauge wire.
j j
(1) Paragraph 6.6.1 of Bechtel procedure FPE 4.000, Revision 4, dated August 5, 1981, was revised to incorporate the above listed concerns.
,
,
l (2) Bechtel NCR 3418 was prepared to document the four cables
)
with jacket damage. Jackets were repaired using Raychem
-
WCSF-N shrink fit tubing. The NCR was closed on July 6, 1981.

.
(3) Bechtel NCR 3417 was prepared to documen;. tae minimum bend radius violation for Cable 2AB6304D. Disposition was use-as-is based on Lew minimum bend radius criteria received from the cable manufacturer for cables not under tension. NCR was closed on August 19, 1981.
(4) Bechtel NCR 3404 was prepared to dacument the minimum bend radius violation for cable 1BD2001AA. Disposition was use-as-is, see NCR 3417 above. The NCR was closed August 20, 1981.
(5) All Class IE coiled cables observed were properly supported.
The inspectors observed non-safety related cable ONB-6103R was being supported by non-safety related cable ONB6119M at the 685' level in the Auxiliary Building. The supporting of non-safety related coiled cables should be consistent with the requirements for safety related cables or this bad practice will again carry over into the supporting of coiled safety related cables.
b.
(Closed) Noncompliance (50-329/81-11-03) Class 2E cable IAY001C in panel IC47 was not separated for non-Class 1E cables INB1705A and INA05001A.
Licensee NCR M-01-9-1-041 was prepared to document the above described separation problem. Cables were separated by the minimum 6" requirement and training was given to the "Termina-tion Crews" and the involved QC inspector.
c.
(Closed) Unresolved Item (50-329/81-11-05; 50-330/81-11-04) It was observed that the vendor wiring was terminated with spaded lugs, in lieu of ring type lugs, in Battery Charger ID17. This item was documented in QAR F-045, dated May 8, 1981.
Project Engineering evaluated the spaded lugs and dispositioned the QAR use-as-is.
Back-up documentation indicates that one of the battery chargers at the Midland plant had been seismically tested.
d.
(0 pen) Noncompliance (50-329/81-11-06; 50-330/81-11-05) Installed cable IBB6404A in Motor Control Center 1B64 had a minimum bend radius violation. Bechtel NCR 3405 wac prepared to document the above identified problem. Bechtel procedure FPE 7.000, Revision S, dated May 11, 1981, has been revised to incorporate minimum I
bend radius criteria for cables inside equipment. As of l
October 8, 1981, NCR 3405 was still open.
This item will remain open until the subject NCR is closed and the disposition verified.
l (Closed) Unresolved Item (50-329/81-30-03; 50-330/80-31-03) The e.
test reports for battery chargers indicated an "0K" for the
" Ohmmeter test to ground from AC input, DC output and alarms."
,
l The inspector requested a minimum value for the "0K" notation.
l Solidstate Controls, Inc. (battery charger fabricator) letter
to Bechtel Professional Associates, dated May 27, 1981, states
!
that an "0K" indicated that the minimum resistance value was (
equal to or greater than 20 megohms. This satisfies the in-spectors concern.

f.
(Open) Noncompliance (50-330/81-12-07) It was observed that cable 2AB2322B had been installed in Motor Control Center 2B23 with a minimum bend radius violation. This fact was documented on licensee NCR M-01-9-1-06!, dated May 21, 1981. As of October 8, 1981, the subject NCR was still open. This item will remain open until the subject NCR is closed and the disposition verified.
g.
(0 pen) Noncompliance (50-329/81-11-04; 50-330/81-11-03) The inspectors identified 14 instances in the upper and lower cable
!
spread rooms where minimum separation was violated and barriers l
were not shown on the drawings.
Per telecopy message dated October 7,1981, Bechtel has issued four drawings showing the required barriers and indicated forecast issue dates for an additional 74 drawings. This item will remain open until the inspector can verify that barriers are scheduled for those cases where minimum separation can not be maintained.
h.
(0 pen) Noncompliance (50-329/81-11-07; 50-330/81-11-06) It was observed that the licensee failed to translate the marking of instrument sensing lines (IEEE-279) into specifications, drawings,
,
procedures and instructions. Per discussions with Mr. W. R. Bird of Consumers Power Company (CPCo) on October 8, 1981, it is the NRC's understanding that CPCo will identify the instrument sensing lines at the Midland Plants in accordance with the requirements of IEEE 279-1971.
Pending a review of the revised specifications, drawings, procedures and instructions, this item will remain'open.
i.
(0 pen) Unresolved Item (50-329/81-12-07; 50-330/81-12-08) The inspector observed that Consumers Power Company (CPCo) test personnel were determinating and reterminating electrical power and control cables during the process of ongoing test activities.
It was requested that the licensee develop an inspection plan to document these activities. During this inspection, the in-spector met with CPCo test personnel and with MPQAD personnel on this subject. The inspector restated NRC's position that an approved procedure was required to perform these testing activi-ties and that it was expected that MPQAD would audit the test group to verify their compliance with the procedure.
It was suggested-that a checklist be developed as part of the procedure to document that the cable / wire was reterminated on its proper landing point and if changes were required, that these changes be documented and drawings revised so that there it a complete history on the item involved. Pending a review of this procedure and the implementation thereof, this item will remain open.
j.
(0 pen) Unresolved Item (50-329/81-12-08; 50-330/81-12-09) The RIII inspectors identified concerns involving the qualification of Bechtel QC inspectors. The licensee stated than an audit of the Bechtel QC department would be accomplished. An audit was performed in June 1981, however, the results of the audit were inconclusive. The licensee stated that an additional audit would be performed prior to December 31, 1981. This item will remain open pending a review of the subject audit results.

Functional or Program Areas Inspected a.
Observation of Electrical Work Activities (1) The RIII inspectors observed that the licensee's contractor (Bechtel) is installing cable tray dividers in the upper and lower cable spreading room cable trays that presently contain numerous cables. The inspectors expressed a concern regarding how the licensee is going to assure that the pre-sently installed cables are re-trained into the proper cable tray after installation of the dividers. Also, because the newly installed dividers will reduce the effective cable tray area, the licensee's method to assure that the thermal cable tray loading has not been exceeded is of concern.
Pending a review of the above listed concerns, this item is unresolved.
(50-329/81-20-01; 50-330/81-20-01)
(2) The RIII inspectors observed that when cable tray dividers are installed, the dividers present sharp edges due to design and the method of installation. The licensee has documented this fact on Audit Finding Report (AFR)
M-01-46-1-03.
Pending a review of the AFR's disposition and corrective action implementation, this item is open.
(50-329/81-20-02; 50-330/81-20-02)
(3) The RIII inspectors observed that cables are not being tied down at 10' intervals as required by Bechtel procedure FPE 4.000, Revision 4, paragraph 6.4.
The licensee has pro-perly documented this fact in accordance with QA Program requirements on NCR M-01-9-1-122.
(4) The RIII inspectors observed that cable trays are being filled above the side rails. This is not in accordance with the requirements of the Midland FSAR, paragraph 8.3.1.4.1.
The licensee has documented this fact on NCR M-01-9-1-116 and QAR F119. Pending a review of the dis-position and implementation of the specified corrective actions for both the NCR and QAR, this item is open (50-329/81-20-03; 50-330/81-20-03)
(5) During a tour of the main control rooms it was observed that the licensee had not color coded the various safety related instrument s, recorders, switches, etc. This item will be followed up by the NRC Human Factors Review Team in accordance with NUREG/CR-1580, " Human Engineering Guide to Control Room Evaluation".
(6) The RIII inspectors observed the in process installation of Class IE cables IAFWO96C and 1AY3114A at the 640' level.
The cabies were being pulled through cable trays IAHB14, 1AJB17, 1AJB18, 1AJB19, 1AJB13, 1AJB12 and 1AJB11. These circuits originate at Auxiliary Shutdown panel IC114 and-5-

(2) The RIII. inspectors observed that Bechtel Procedure FPE
'
- -
4.000, Revisioni4, " Installation and Rework of Electrical Cables", did not address in detail how the licensee was going to verify that the cable pulling tension had not
,
been exceeded when small cables and/or instrumentation
-
cables were pulled.
'(i.e., cables that have a maximum l
'
pulling t6nsion that is less than the force that can be
-
exerted on the cable by one person). Tests performed on s
another project indicates that a man can exert approxi-
,
mately 125 pounds pull on a cable.
,.
,
'
Pending a review-of cable pulling records to verify that
.-able pulling tensions have not been exceeded, this item
'
is unresolved.
