Dear Mr. Grier:
On August 30, 1978, in accordance with 10CFR50.55 (e), we reported verbally to Recion I a deficiency with miscellaneous electrical fittings used in the installation of cable tray and conduit.
This deficiency was determined to be reportable since several types of fittings, which might have been utilized in Category I systems, were supplied by a vendor other than listed in a field use specification.
The Shoreham field use specifications list specific manufacturers and model numbers whenever field purchas-i ing of non-engineered items is required.
Both Power Strut and Uni-Strut were specified as manufacturers of cable tray and con-duit support fittings.
This letter serves as our 30 day written report for this deficiency.
()DescriptionoftheDeficiency i
Purchase orders for all electrical cable tray and conduit support I
fittings specified Power Strut material by catalog number, as required by the field use specification.
Power Strut is manufac-
- l tured by the Van Huffel Tube Corporation, Warren, Ohio.
The pur-
-]
chase orders did not permit substitution of material or manufacturer.
All orders for the above fittings were placed with a distributor, Modern Suppliers and Manufacturers, New York.
This was due to the fact that Power Strut (Van Huffel) would not accept orders placed directly with them.
Modern Suppliers took no exception to the pur-chase order requirements and supplied certificates of compliance with every order stating that the fittings supplied met "all re-quirements and specifications shown in the Power Strut Catalog #5P."

An incident 6eveloped where the site FQC organization discovered that several items supplied by Modern Suppliers were obtained from Marengo Tool and Die Makers, Marengo, Illinois.
This inci-
'I dent was therefore reported because Marengo was not considered to F
be an acceptable supplier in accordance with the specification.
l An investigation was undertaken to establish the acceptability of j!
the fittings. supplied by Marengo.
The investigation determined T'
that the Marengo fittings are acceptable for use at Shoreham y
based uoon the following:
il t
a.
All materials supplied meet the following requirements:
i FITTING CRITERIA i
POWER STRUT MARENGO Flat Bar ASTM A-575 ASTM A-575 -or-Maderial ASMT A-569 (sheets C-1008 to C-1010)*
Finish ASTM A-164 and/or ASMT A-164 and/or Fed. Spec. 00 Fed Spec. QQ-Z-325-B 325-B G
- Stone and Webster engineering has determined that material con-I.j 1
forming to this standard is acceptable.
b.
Marengo is a supplier to Power Strut for welded fittings.
c.
All orders from Modern Suppliers were receipt inspected on site in accordance with Field Quality Control' Procedures.
These procedures call for a sampling program in accordance with Mil-Std. 105-D.
Every item on every order was inspec-ted in this manner.
Inspections were documented and re-jected material was returned to Modern.
Inspections consisted of a visual check for dimentions, finish, welding, cracks, and general quality of workmanship.
d.
Final installations of cable tray and conduit supports are inspected in accordance with Section 12.1 of the Field Quality Control Procedures.

1 None required.
All purchase orders will continue to specify Power Strut or Uni-Strut fittings by catalog number.
Future
.I orders will not be placed with Modern Suppliers due to commer-
?l cial problems experienced with this distributor.
!i ji Our 30 day response for this deficiency is being submitted 11 i
days later than the nominal due date of September 29, 1978, because of a delay in accumulating the required data.
Mr. A.
1 Toth (NRC) was notified of the delay pricr to September 29, and agreed to an extension until October 10.
