3 Interroaatory No. 1 Indicate total number of welds involved directly or indirectly with safety-relatd piping, reactor vessel, reactor vessel components and all units into and out of the reactor vessel which require or required welding.

Answer Using various techniques, it has been estimated that there are over 195,000 safety-related welds joining safety-related piping, reactor vessels and reactor vessel internals for the Limerick Generating Station.

The preceeding estimate includes safety-related piping into and ot* of the reactor vessel.

Interroontory No. 2 Indicate the types of each weld performed and the name and proof of qualification of the welder who performed such veld or welds.

Answer The types of field welds performed at Limerick Generating Station for safety-related piping, reactor vessels and reactor l

vessel internals are shown on the associated drawings, and specifications for the particular comoonent, system, or piping.

Additional welding details are found in the field welding procedures, a list of which is attached.

Each welder is qualified to perform welding to the appropriate welding procedures that he is using.

The following description is provided as an example of the controls applied at Limerick to assure that a welder is qualified to the procedure to which he is working:

When a field piping veld is to be perfelied, it is verified that the welder assigned is qualified prior to issuance of weld filler material.

During the performance of the weld, the quality control inspector verifies, during surveillance inspections for selected pipe welds, that authorization has been granted for the weld filler material in the welder's possession, and that the welder is qualified to perform the weld.

To retrieve the inspection records and associated information for field pipe welds, the weld must be selected and identified by 3

' pipe lino number, drawing number and field weld number.

Onco the weld is selected, the specific type of wold can 'tje identified, the welding procedure which was used and the welder (s) identification by review of the inspection recor:t und associated documents.

Witn the welder's identification, his qualifications to the welding procedure can be retrieved.

The above information and proof of welder's qualifications are stored on site either in hard copy or in microfilm.

While there are variations in the methods unod by vendars and subcontractors, controls equivalent to those described f or field pipe welds are applied as required by their QA programs and implementing documents.
