Independent Inspection Effort A general plant tour was made and the following areas of interest were
examined by the inspector:
a.
General' construction activities and conditions such as housekeeping were observed in the reactor, auxiliary, and fuel buildings for Units A1.and A2.
b.
The inspector observed welding of structural steel in the Unit Al HPCS pump room.
The applicable ccde for this welding the AWS Structural
~
Welding Code D1.1, revision 2-74.
Welding of Beam 2414A2 to Channel 28L-28A on CF Braun drawing S-286 was observed. Welder qualification,
.use of the correct welding procedure and use of the correct welding material were verified.
Within the areas inspected, no violations or deviations were identified.

(Closed) Item 518, 519, 520, 521/79-30-02, " Improper Heat Treatment of Reactor Pedestal Studs". Based on previous IE:II inspections (see Rpt' Nos.
.
518, 519, 520, 521/o0-07; 518, 520/80-20; 519/80-19; 521/80-18), the licensee has added two letters - J. L. Parrish to Daniel Pelecovich dated 10/9/80, covering justification for accepting studs after TVA sampl'e inspection revealed rejectable studs and J. L. Parrish to Daniel Pelecovich dated 12/10/80, covering sequence of events during heat treatment - to the record package. The inspector reviewed the above-two letters and the record package for Heat Lot "A",
Heat Code C-41 studs. Based on this review, the
. previous IE:II' reports listed above, and the licensee final report, this
' item is closed.
7.
Safety-Related Piping (Units Al and A2) ~
