Site Tour Routine tours of the site were unde to observe the status of work and construction activities in progress. The plant construction is presently 48 percent complete. Work items were examined for obvious defects or noncompliance with regulatory requirements. Areas inspected and findings are described below.
a.
Five major components were transported from storage, moved through the containment building construction opening, lifted by the polar crane and set in place. The itens were: neutron shield tank, three stean generators and the reactor pressure vessel. 'Ihe inspector performed daily nonitoring of these activities and reviewed certain nonconformance and disposition reports associated with setting the stean generators and reactor pressure vessel in place.

h inspector witnessed drilling in the concrete. floor Auxiliary Building for the purpose of installing concrete anchor bolts. The means for controlling d===
to imbedced rebar was demonstrated to the inspector. An electrical device called a 'ht" installed in the electrical supply line of the drill acts as an electrical isolator whenever the drill comes.in contact with ground,ing to.
such as a rebar. The demonstration was made by intentionally try drill into rebar. Each time the machine turned off without d= aging the rebar, c.
The inspector selected welds 2-SIS-011-W2, 2-SIS-067-W2, 2-SIS-071-F02 and 2-SWS-185-F19 and performed a visual exanination to assure. code coupliance. This included the use of aids such as weld gages and drawings. The inspector inspected the surfaces for finish, undercut, reinforcement and concavity.

d.
On. November 30, 1981 a detailed audit was made of the weld rod issue station 6 located in the reactor building. The inspector' checked segregation, weld rod issue, peratures, weld rod identification and furnace calibration, aven tem inventory log and disposal of scrapped electrodes.
No itens of noncompliance were identified.
