General At the pre-inspection meeting with the licensee's representatives, the inspector stated that this inspec, tion vould cover review of the status of outstanding items and the QA programs for piping and electrical work.
The inspector was informed that testing was in progress on several systems including the nuclear service river water and the nuclear services closed cooling water systems. The operating floor of the fuel handling building has been turned over to operations and receipt of fuel vill begin late in September.

system, the condition of the fuel handling building at the operating floor and the crack in the seal weld of the secondary river water /

Cracks had been reported by the licensee in three heat exchanger's of this type.

3.
Outdoor Storace of Electrical Cable Clarification of the requirements for protective covering of electrical
.
cable in outdoor storage and testing of exposed cable had remained unresolved during a previous inspection. (Inspention Report 50-320/
76-09)
The inspetror examined Rev. 17 of UE&C Procedure ECP-3-2.
Paragraph 4.4.5 of th.!s procedure has been revised to require that power and control cab;.e be covered when the stocage period exceeds or is expected to exceed one year.
Instrument cable is to be covered or located undar a roof whenever it is in storage. Paragraph 4.7.7.
-
has been rr. vised to require records of return of cable to storage
'
to be maircained on Reel Record Cardc.
The inspector audited a group of Meel Record Cards and observed that the dates of return to storage had been recorded where applicable.
The inspector also examined the report of dielectric and resistance tests performed on sample reels of cable which had been stored out-doort withoni protective covering. "The exposed cable was identified on Jeviation Report (DR) No. 0614 and disposition of this DR included tests of sa=ple reels of cable.- The tests were conducted on reels Nos. B-7071 and B-5565 (15 conductor No. 12 Kerite Cable "EK-9-J")
and Nos. B3593 and X-4559 (7-conductor No. 4 Kerite Cable "EK-6-A").
The tests were conducted by Continental Cable and Wire Company and were witnessed by the licensee's representative.
The test report dated August 10, 1976 showed the result of the tests to l
.
Le equivalent to the results of similiar tests originally performed
,
by the manufacturer.

Electrical Circuit ' Terminations A number of the circuits observed during inspection of installation of electrical power and control cables (Paragraph 7 of this report)
were energized.
The inspe; tor was therefore unable to observe the circuit terminations with the exception of circuits MA6C and MA90C.
l The circuit terminations in circuit MA90C, local Control Station i
BSV4A of the Auxilliary Building, elevation 280' were terminated in a good workmanlike manner.
The MA6C circuit in Local Control Station DHV4A, did not appear to meet the standards contained in the referenced Electrical Code and handbook,

identification, tray loading, and termination of the circuits were docu=cr ted in the turn over packages in accordance with the requirem?nts of UE&C Electrical Construction Procedure, ECF-3-2 RevisJon 16 for Receiving, Storing, Handling, and
-
I tstalling Uire and Cable.
The turn ove.. packages were current, legible end easily retrievabic from the document contuol vault.
Of the packages listed, all records were signed by a quality control inspector and the nonconformancas listed with a disposition stated.
Quality Control maintains a punch list of the nonconformances, and the disposition stated in the turn over packages is to be completed at a later date and to be verified by quality centrol.
b.
Installation The inspector verified that the circuits were installed in accordance with the pulling reports listed No discrepancies were identified.

Electrical Penetration Connections
.
By letter dated March 11, 1976 the licensee had reportci. as a significant deficiency in accordance with 10 CFR 50.55(3 <, the pres.ence of a mylar material under cable terminal lugs en electrical penetration cables.
Following review by the licensee, the A-E (B&R) and General Electric Company (GE) (the vendor), a program was agreed upon for replacement of cable terminal lugs on all No. 2 cables and for testing all No.
2 and 4/0 cables on a sa=p?ing basis to determine whether internal splices were acceptable.
The sampling program was established at a meeting of GE and the A-E on April 29, 1976.
(Conference Notes No.
1182)
It required testing of five pairs of cables per penetration.
If the results were not acceptable all circuits in the penetration would be tested.
The inspector examined the following documents:
a.
Letters dated July 2, 1976 and July 26, 1976, B&R to CE stating that cable resistance data had been reviewed and in<'
ited thut mylar tape was not present in the penetrations.
(
b.
Letter dated July 28, 1976, CE to B&R stating that re-lugging of the No. 2 conductor and random sampling of the No. 2 and I

4/0 conductors has been completed.
Field documentation of
.
this work was attached and showed four penetrations to have been re-lugged and 10 penetrations, including the above four, to have been resistance tested.
-
The inspector checked these penetrations against a listing and description of the GE low voltage penetrations and determined that the penetrations tested included all No. 2 and 4/0 cables.
This item is resolved.
9.
Condensate Storace Tank Drawings Lack of updated B&R drawings of the condensate storage tank had been identified as an unresolved item.
(Inspection Report 50-320/
76-08)
The inspector examined B&R drawing No. 2217, Rev. 12.
This drawing showed the two additional 6-inch nozzles and noted that the field was to provide two 6-inch blind flanges for i.he existing nozzles.
Drawing No. 2217, Rev. 12 is in agreement with the contractors (PDM) drawing E-6.
(Contract No. 13041)
This item is resolved.
10.
Dynamic Stress Calculations Preparation of dynamic stress calculations on the main steam and pressurizer relief valves had been identified as an unresolved item. (Inspection Report 50-320/74-04)
The inspector examined the following:
a.
Main Steam Relief Valve B&R letter dated February 22, 1974, Serial No. 1224-GP, enclosing final report " Analysis of Main Steam Safety Blow-off."
This report concludes:
(1) The stresses at all critical locations are within the limitation.of equation (9) Paragraph NC-3652.2 (Winter 1972 Addenda to ASME Code,Section III)
(2) The stiffness of the trunnion support at the discharge elbow is sufficient to preclude excessive flow-induced vibrations.

Pressurizer Relief Valve
.
B&R Report No. 7.00.006 dated June 25, 1976, " Pressurizer Relief Valve Discharge Piping Stress Analysis." This report concludes, in part, "The stress developed in the discharge piping system due to pressure, seismic, dead weight, and thermal expansion of the piping system were compared with the stress limits as defined by ANSI B 31.1... 1967 and were found acceptable."
Paragraph 3.2.2 of this report imposes a requirement for the dead weight support system and states that Bergen-Paterson (B-P) vill be notified of this requirement.
The inspector observed that B-P was furnished this information by letter from B&R dated October 6, 1975.
The inspector was informed that review of this report by GPU was in progress but had not been completed.
This item remains unresolved pending completion of this review.
