Shearon Harris Nuclear Power Plant Draft SER Open Item No.
354 NRC Ouestion 210.47 Pum Nozzle Loads The Design Specification CAR-SH-M-13, Rev. 8, dated 5/4/83 (6.1) says that in no case shall the acceptable reactions due to thermal loading plus the seismic loading be lower than:
Mr ~ 250 SM where M
resultant moment in any direction, ft-lb SM section modulus of metal pipe connected to pump nozzle, cu in.
The Specification (6.3) indicates that SM is for Schedule 40 pipe; hence, for the 14-inch nozzle:
Mr 250 x 12 x 61.4 184,200 in-lb of 28,920 in-lb.
(a)
Explain the seeming discrepancy where the Specification requires a
minimum 14-inch nozzle load capacity of M 184,200 in-lb; whereas the Stress Analysis uses about one-sixth of tlat moment as the maximum load acceptable to the pump manufacturer.
(Also see 0210.66)
The Seismic Stress Analysis ME-529 dated 4/14/78 for the Service Nater Booster Pump (Model 3405L) (4.2) cites a maximum resultant moment for the 14" Section
RESPONSE
Paragraph 6.1 (Part-II) of Specification is a general requirement for the equipment nozzle load.
The nozzle loads specified are based upon a proportion of the pipe allowable stresses, which conservatively insures structural integrity of the piping system and avoids excessive deformation to the connecting equipment.
This paragraph is imperative during the equipment contract evaluation phase of the prospect.
In this, case, manufacturer (Goulds) had taken exception during the bid phase, (see attached proposal dated 3/20/1973),
from the Ebasco specified nozzle loads.
Manufacturer has indicated that their acceptable nozzle loads in the stress report (see attached ME-529 Add.
page 13, paragraph 4.2).
Based on manufacturer's acceptable nozzle loads, Ebasco is checking piping design system load requirements against manufacturer's acceptable load.
Eventually, piping system shall be designed to mutually acceptable nozzle loads between manufacturer and Fbasco.

354 NRC Ouestion 210.48 Pum Seismic Loads The Design Specification CAR-SH-?f-13, Rev. 8, dated 5/4/83 (Attachment No. 5, 4.1) says that "Static coefficients will be furnished to the Seller at a later date."
The Seismic Stress Analysis HE-529 dated 4/14/78 (4.1) says "The seismic loadings applied exceed those given by the specification Explain how the statement in the Stress Analysis could be made in view of the seeming absence of static coefficients "by the specification."
RESPONSE
Pump assembly frequency has been determined by using frequency analysis.
In applying the frequency analysis the following steps were talcen:
(a)
Develop dynamic model.
(b)
Compute resonance frequencies (by computer analysis ICES-STRUDL program).
(c)
Frequency excess 33 Hertz, therefore, equipment is rigid (pump assembly frequency is 41.5).
(d)
Then use floor response spectra curves.
(These curves are part of the specification for the specific floor level RAB 236').
Therefore, static coefficient does not apply for the frequency analysis.

354 NRC Ouestion 210.49 Pump Pressure Boundary Integrity (a)
What checks were made of the pressure boundaries of the centrifugal pump; e.g.,
of the casing bolts?
(b)
The Design Specification CAR-SH-H-13, Rev. 8, dated 5/4/83 (9.1) says that "Shop hydrostatic shall be made on all pump casings."
What was the hydrostatic test pressure and why is it not specified in the Specification?
Provide a copy of the NPV-1 data report applicable to the pump covered by the Stress Analysis HE-529 dated 4/14/78.
RESPONSE
(a)
Hydrostatic test has been performed on the pressure boundaries of the pump as per Goulds'rocedure OCP No.
120 (attached).
(b)
Hydrostatic test shall meet the requirements of the ASHE Boiler and Pressure Vessel
- Code,Section III and test pressure at no less than one and one half (1 1/2) times design pressure.
Pump design pressure is indicated on specification Part
- One, Page 5, paragraph 6.13.
The NPV-1 data report is attached.
