Carolina Power 8 Light Company SEp 2 188'ERIAL: NLS-87-167 10CFR50.

United States Nuclear Regulatory Commission ATTENTION: Document Control Desk Washington, DC 20555 SHEARON HARRIS NUCLEAR POWER PLANT DOCKET NO. 50-000/LICENSE NO. NPF-63 PERFORMANCE TESTING OF RELIEF AND SAFETY VALVES Gentlemen:

Carolina Power R Light Company (CPRL) hereby submits additional information concerning NUREG-0737, Item II.D.1, "Performance Testing of Relief and Safety Valves," for the Shearon Harris Nuclear Power Plant (SHNPP).

This information addresses pipe supports for relief and safety valve piping in response to verbal questions from the NRC staff.

As discussed in Supplement 3 to the NRC Safety Evaluation Report (SER),

Section 3.9.3.3, piping supports at SHNPP were designed in accordance with ANSI B31.1, "Power Piping" (1973), supplemented by the American Institute of Steel Construction (AISC), "Design, Fabrication, and Erection of Structural Steel Buildings," Seventh Edition, February 1969.

The principle guidelines for pipe support design are included in the Harris Plant Engineering Section Manual of Instructions, Design Guidelines Section 7.2.A, "Piping Support/Restraint Design and/or Modification." As stated in SER Supplement 3, the NRC has determined that the applicability of the codes and standards used for pipe support designs is acceptable and that conformance of the design guidelines to the appropriate codes and standards is adequate.

In the SHNPP support design, each design level has a corresponding allowable stress.

The following table lists the stress allowables at each design level:

Loading Flexure Shear EQ 2 (Normal or Upset)

EQ 6 (Emergency)

EQ 8 (Faulted)

S 1.33S 1.5S S

1.3S 1.3S For standard components,,the loads at each design level are compared to the corresponding manufacturer recommended allowable.

As shown above, the allowables for EQ 6 are more restrictive than those for EQ 8. However, this fact is of no consequence to the piping supports in question because the reactions for both EQ 6 and EQ 8 are equal.

Since the allowables used for all these supports were either Equation 2 allowables for EQ 2 loads; or EQ 2 or EQ 6 allowables for EQ 6 and EQ 8 loads, the designs are conservative and meet the design guidelines.

The enclosed table shows what is perceived to be the most critically stressed support component (i.e., rolled member, weld, manufactured hardware item) and its respective stress or load allowable at each support.

If you have any questions concerning this information or require additional information on this subject, please contact me.
