Site Tour The IE inspector walked through various construction and storage areas
'
to observe construction activities in progress and to inspect the general state of cleanliness and adherence to housekeeping requirements. The i
tour included the Reactor Building and Reactor Auxiliary Building.

Reactor Coolant Loop Piping
,
The IE inspector reviewed procedures No. N-8-8-B-1, Rev. 5, and NM-8-8-B-1,
Rev. 3, for the tack welding and production welding of reactor coolant
!
piping.
Both appeared to be in compliance with the requirements of Section 3 of the ASME Boiler and Pressure Vessel Code. From a review of personnel records, it was determined that all four welders engaged in the welding of reactor coolant piping at the time of this inspection were properly qualified to the welding procedures being used.
Initially, the Dimetric welding equipment was assembled for use on the cold leg of Loop #4 and weld metal was deposited to a thickness of approximately inch for Joint No. F-402 and a thickness of approximately 2 inches for Joint No. F-401.
The cold leg of a reactor coolant loop connects the
.
coolant pump with the reactor vessel and conveys coolant back to the
,
reactor vessel from the steam generator. Welding was stopped on Loop
'
- 4 at this point to allow for in-process radiography and moving of the welding equipment to Loop #2.
j Some indications were noted on the radiographic film for Joints F-401 and F-402; but most were attributed to anomolies acceptable within the base material specification. One rejectable weld indication was noted on Joint i
No. F-401 which was subsequently removed.
Repair welding of this area will be accomplished prior to resumption of production welding on this joint.
The IE inspector verified the fit-up and tack welding operations on Joints F-201 and F-202 on reactor coolant Loop #2.
The jig transit record-ings for determining the location of the reactor coolant pump casing were i
verified and found to be within the allowable tolerances prior to welding.

i The IE inspector witnessed the deposition of the root pass and most of the first one inch of weld thickness on Joint F-201.
No reactor coolant loop welds have yet been completed, thus no final records were available for review. The traveler packages for Joints F-201 and F-202 were inspected for completeness and accuracy of the in-process entries.
No items of noncompliance or deviations were noted.
4.
Exit Inte rview The IE inspector met with licensee representatives (denoted in paragraph 1) at the conclusion of the inspection on August 14, 1980.
The IE inspector summarized the purpose and the scope of the inspection and the findings.
