. Licensee Action on Prefious inspection Findings (Closed) Unresolved Item (341/78-02-07): There was no follow-up audit by the licensee of Daniel International.
The inspector reviewed Detroit Edison's audit of Daniel International, (Clcsed) Noncompliance (341/78-05-06): Safety-related electrical supports having unacceptable welds were not identified.
This inspec- , tion revealed that welds in electrical support and tray systems had been inspected and repaired in accordance with S&L acceptance standard DCN 984, Revision D.
All hold tags had been removed.
(Closed) Unresolved Item (341/79-05-03): Seismic qualification test results for York Electro-Panel Control Company instrument racks.
The inspector reviewed York-Electro panel seismic analysis of wall mounted instrument racks, Final Report No. 77113-1 dated December 29, 1977, and seismic analysis of floor mounted instrument racks, Final Report No. 77113-2 dated December 29, 1977.

The inspector reviewed the licensce's audit schedules for September through December 1978, and January through June 1979.
Seven audits of Daniel International are scheduled through June 1979.
Two of these audits have been completed and one was in progress during this inspection.
This items is considered closed.
(Closed) Unresolved Item (341/78-16-02): Magnetic Particle Reports: The inspector was informed that PT and MT reports for Section III piping fabricated by Dravo will be maintained and stored by the fabricator. The licensee further stated that past audits and reviews of Dr vo's facilities and programs were successful.
(Clused) Unresolved Item (341/7'-16-03): Piping Material Certifi-cation: The inspector ascertained that the components in the subject material certifications were fabricated from pipe and the piping material specification was met.
(Closed) Unresolved Item (341/78-18-01): Jet pumps numbered 4, 8, 10, and 12 hai a different appearing welds. Fxcessive weld spatter on jet pumps numbered 6,11, 15, 18, 19.
The inspector reviewed GE letter File No. 1267 dated December 12, 1978 subject; " Letter of Clarification on Jet Pump Mixers" and WPS P504P102 " Arc Welding of Austentic Stainless Steel" This procedure allows several methods for welding of the jet pumps. The inspector also reviewed GE's FDDR No. KHI-117 dated November 17, 1978 and traveler KH-117 which indi-cated that welo spatter had been removed from all jet pumps (20 EA) -3-466 255
