Dear Mr. Stello:

NRR INFORMATION REQUEST DATED MAY 25, 1979 PWR FEEDWATER LINES NO. 1 UNIT SALEM GENERATING STATION June 14, 1979 In response to your letter of May 25, 1979 transmitting the subject request which was received on May 29, 1979, we offer the following pursuant to items 1 and 2 with respect to design and fabrication history:

Design

1.

Isometric drawings of each steam generator feedwater*

pipe line from the containment wall to the steam generator nozzles shows the design, dimensions, pipe schedules, support types, location and pipe restraints.

There are no in-line valves in this section of the feedwater piping.

The steam generator sparger is internal with no* weld attachment to the steam gener-.

ator nozzle.

The Sparger has J tubes attached to the sparger header for flow distribution.

2.

A S1,lmm*ary of thermal and seismic stress analysis results performed for this system.indicates the stresses at the 9team generator nozzle and the location of other stress points including the maximum. *

9 o s z 2 o s<or.

Mr. Victor Stello, Jr. 6/14/79 Fabrication History

1.

The steam generator sparger material is carbon steel.

The steam generator nozzle material is SA508 Grade 2 and the feedwater piping materials are shown in the tabulation attached to each isometric drawing.

The O.D. of the attachment to the steam generator nozzle is 16~" to provide for the difference in the material match to the steam generator nozzles.

2.

Welding details for nozzle to pipe and piping welds are shown in the attached tabulation entitled, Salem Nuclear Generating Station, Steam Generator Feed Pipe Field and Shop Weld Fabrication History."

There is no weld attachment at the nozzle for the steam generator sparger which is an internal slip joint.

This is the information requested within 20 days.

The additional information requested within 60 days is being accumulated and will be supplied subsequently.

Sincerely, Attachment CC Mr. B. H. Grier NRC, King of Prussia, Pa.

Mr. L. J. Norrholm NRC, Hancocks Bridge, N.J.
