TU Electric Letter No. TXX-6133 dated December 4, 1986
Dear Ms. Williams:
In References 1 and 2, CYGNA requested information to facilitate its review of pipe stress and pipe support issues.
The requests of Reference 1 were partially fulfilled by Reference 4.
CYGNA, in Reference 3, updated its information request to reflect progress of the Reference 1 and 2 meetings and to acknowledge receipt of the documents transmitted via Reference 4.
Attached are 3 copies of outstanding documents requested in Reference 3.

SUMMARY
ORS 40, 3, dated January 6, 1984 Attachment G JUSTIFICATION FOR THE USE OF NELSON STUD DATA FOR THE BASES OF REDUCED HILTI SHEAR CAPACITY These attachments represent partial fulfillment of CYGNA's outstanding request for information of Reference 3.
1.
Pioe Stress Issue No. 1. MASS PARTICIPATION / MASS POINT SPACING CYGNA requested that,SWEC justify terminating Comanche Peak piping response spectrum analysis at 50 HZ instead of at the frequency corresponding to the zero period acceleration.
Attachment A fulfills this request.
2.
Pioe Stress Issue No. 20. ANSYS STEAM HAMMER (FLUID TRANSIENT) ANALYSIS CYGNA requested that SWEC address the following concerns with SWEC's Fluid Transient Analysis:
The adequacy of mass point spacing for fluid transient analysis.
a.
b.
Accuracy of including more than 50 percent of the extracted modes.
Determination of the dominant frequency of the input forcing function.
- c. fulfills this request.
3.
Pioe Stress Issue 28. DESIGN of SEISMIC /NONSEISMIC INTERFACE ANCHORS CYGNA requested that SWEC respond to the CYGNA concern that piping can supply close to full plastic bending moment and close to full plastic torsional moment simultaneously.
Attachment C fulfills this request.
4.
Pine Suonort Issue 3. RICHMOND INSERT ALLOWABLES CYGNA requested that SWEC demonstrate that the reinforcement in the a.
Richmond Insert Test Slab is representative of field conditions.
b.
CYGNA requested SWEC provide Attachment C.
The response to request 4a will be submitted later.
Attachment D fulfills the request of 4b.

5.
Pine Succort Issue 7. CINCHED U-BOLTS In Reference 4, SWEC was to forward the test report for the SA-36 relaxation tests. With the elimination of cinched U-Bolts, this request need not be fulfilled, since the issue is now closed.
6.
Pioe Succort Issue 16. DUAL STRUT / SNUBBER DESIGN CYGNA requested that SWEC provide the load capacity data sheets (LCD) and certified design reports (CDRs) for riser clamps to clarify that essential load cases are considered in the design of riser clamps.
The NPSI riser clamp load capacities, Attachment D, are based on the pipe load being carried equally on both arms.
This is the typical spring hanger application for NPSI riser clamps. SWEC engineers compare the higher of the two loads against one-half the CDTRS value, in accordance with NPSI requirements of Attachment D, third paragraph for struts and snubbers, to assure that the NPSI riser clamps are qualified in the event that there is an uneven distribution of load between the two arms.
Grinnell riser clamp load ratings, Attachment E, are based on 100 percent of the load being carried on one arm.
Therefore, Grinnell riser clamps are automatically qualified for the worst-case occurrence of uneven load distribution.
For spring hanger applications, where each arm sees 50 percent of the load, the load rating may be doubled.
The above explanation and Attachments E and F fulfills this request.
7.
Pioe Succort Issue 42. ALLOWABLES FOR HILTI ANCHORS HAVING EDGE DISTA LESS THAN 50 CYGNA requested SWEC to justify the use of Nelson Stud Test Data as the basis of reduced shear capacities for Hilti bolts with edge distances less than 50.
Attachment G fulfills this request.
