Subject:
Auxiliary Feedwater System Project San Onofre Nuclear Generating Station Unit 1
Reference:
Telephone discussion with Mr. G. J. Stawniczy dated September 23, 1981 This letter confirms information transmitted to you by Mr.
Stawniczy in the course of your telephone discussion of September 23.
- 1) Support 381-A-Gl-15; per drawing no. 518062-3, detail 14, this support is a biaxial guide (G-2),
and does not restrict motion along the axis of the pipe.
- 2)
The dimension between nodes 48 and 49, on the stress isometric for line no. 69-3"-EG is 2 ft. 10 in.
- 3)
The tie-in point for-'line 69-3"-EG, as shown in the enclosed isometric
- sketch, at node' 1, is shown marked up on drawing no.
450339-0, also enclosed.
The distance between the anchor and the first elbow downstream is 2 ft. 5 1/4 in.
- 4) For the 14" expansion joint on line 721-14"-EG, the spring constant to be used for stress calculation is 1650 lbs. per inch compression and 825 lbs.
per inch tension.
This joint is a 14" garlock rubber expansion joint which has different spring rates in tension and compression.
