Plant Tour The inspector conducted a walk-through plant site tour of Units 1 and 2-containments, reactor buildings, and other safety related structures to assess the work procedure and gene il conformance to good practice in the areas of temporary storage, er._ tion and installation of structural steel. A licensee QA engineer accompanied the inspector on this tour.
No items of noncompliance were identified.

' Observation of Work for Safety Related Structural Steel The inspector observed and inspected some completed' structural steel
. items to determine that the items are of the type specified, are properly fabricated, are properly installed as specified by design, and specific clearances and critical dimensions are maintained.
The inspector inspected the following structural steel beams in reactor and other buildings:

HB-190; HB-140; HB-141; HB-218; HB-219; HB-273; HB-166; HD-61; HD-133; HD-197.
During this inspection the inspector observed that some beams designed for seated connection did not have a " Top Angle" as required by AISC manual of standard practice for seatea beam connectors.
The inspector reviewed the applicable drawing showing the details of such connections.
The drawing no. C-849, RW 15 did show the top angle, however, a note
. indicated that these angles would be used if required and shown on framing drawings.
The applicable framing drawing did not show any top angles. The inspector requested the licensee to provita an engineering rationale for this ommission and a departure from an accepted standard practice.
In response to the inspector's questions the licensee stated that the ommissions of top angles are a deliberate design decision. The engineering rationale for the ommission are as follows:
C (1)
The " top angle" required by AISC is to provide for a overturning restraint for a seated beam.
-(ii)
This restraint in the seated beam connections is provided by approximately two feet thick concrete slab on top of the beams.
(iii)
Stiffeners have been provided at the end of beams to prevent 5,e flange and/or web buckling.
However, the inspector pointed out to the licensee that there were beams with seated beam connection without concrete slab over it.
These beams support steel floor gratings. Also, the end stiffeners do not provide restraints for overturning of the beam. The inspector requested that the licensee provide further information to support the ommission of angles; specifically, an analysis to show that concrete provides at least an equal to or greater resistance to overturning than top angle; where there is no concrete, one bolt on the lower flange is able to resist all the tensile stesses and moments generated by overturning. The licensee ind.icated that these informations would have to be obtained from their A/E's home office in San Francisc.o, California, and would take some time. The inspector indicated that this item was unresolved and would be followed-up in a subseqent inspection. (50-354/81-01; 50-355/81-01)

Review of Documentation Associated with Structural Steel Items The inspector reviewed pertinent documentation and held discussions with licensee and construction personnel to verify that quality control-operations were adequate, project procedures were implemented, and the records were maintained. The inspector reviewed the following documents.

Manual". Sec. 4 Based on the review of above documents and discussion with licensee personnel, the inspector determined that the erection and installation of structural steel was generally proper, except as discussed in the previous paragraph, and adequate records were being maintained.
However, the licensee was not able to provide some material certifications for structural steel used in category I structures.
The licensee in-formed the inspector that due to the change over of document control system from manual to computerized record management system, there are
some problems in retrieving records.
The inspector indicated that the material certification will be reviewed at a subsequent inspection.
