Pace 4 of 31 Page Number LO Obiective The scope of this calculation is to analyze the ovenurnmg moments in the Bottom Pressunzer MNSA, the Hot Leg PDT MNSA, and the Hot Leg Sampling MNSA, resulting fmm a 1 G seismic loading applied to each design. The calculated values for the Bottom Pressunzer MNSA will be compared to the two new design's values.

NOTE: The Hot Leg RTD nozzle MNSA is not evaluated here. It is id .itical to the fully qualified Southem Califomia Edison, San Onofre Units 2 & 3's RTD MNSA clamp (See reference 3.2).

Under seismic conditions the inen:ase in load reacts against the preload in the Hex Head Bolts, which would result in a loss of sealing pressure, or anti-ejection capability. By showing that the overtuming moment of the Bottom Pressurizer MNSA, subjected to the seismic load, is equal or greater than either the overtummg moment values of the Hot Leg PDT, or Hot Leg Sampling MNSA, we can conclude that seismically testing the two new MNSA assemblies is unnecessary because the loadings in the two new designs will be less than the loadings the Bottom Pressurizer MNSA was subjected to during qualification testing (Reference 3.1) 2.0 Analvtical Techniaues (Method)

The method used to calculate the overturnmg moments is hand calculations, utilizing the principles of mechanical design. Further calculations will be performed to detemline the force acting to offset the Preload in the four Hex Head Bolts, created by the overturmng moments, Hot Leg PDT, and Hot Leg Sampling MNSA's. The unloading force values for the Bottom Pressurizer MNSA will be compared to both the Hot Leg PDT MNSA and Hot Leg Sampling MNSA values, since there geometry and bolt circles are different.

Definitions used in this calculation are as follows:

RTD -

Resistor Temperature Detector.

PDT - Pressure Differential Transmitter.

MNSA - Mechanical Nozzle Seal Assembly.

BP -

Bottom Pressunzer.

SG -

Steam Generator.

9.0 CONCLUSION

Under a representative IG load, the offseting loads created in, Hot Leg PDT MNSA's is less than the loads created in the BP MNSA. Therefore the statement can be made that the Hot Leg PDT MNSA designs is "seismicaly qulified" since it would be tested to the same response specturm as the EP MNSA in Reference 3.1 The Preload O..seting Force calculated above are sumarised in the below table Clamp P.O.F. Section BP MNSA 37.8 Lbs. Section 7.1 H.LP. MNS A 27.7 Lbs. Section 7.2 HLS MNSA 46.4 Lbs. Section 8.1 The offseting load calculated for the Waterford Sampling Nozzle MNS A is greater than the offseting load calculated for the Bottom Pressu izer MNS A that was test :d. Therefore the Waterford response spectra will be compared to the test spectra. Then thc ratio of the two calculated moments will be used to establish a "g" loading to demonstrate that the test conditions envelope the Waterford design conditions. This will be done in ABB Rep]rt No. C-NOME-ER-0120," Design Evaluation of MNSA for Various Applications at Waterfrrd Unit 3".

Page 25 of 31 Page Number 10.0 ASSESMENT OF SIGNIFICANT DESIGN CHANGES This calculation evaluates the MNSA design for Waterford and is based on previous designs of MNSA clamps for San Onofre Units 2 & 3. The only significant design change is the length of the tie rods. This calculation incorporates the new lengths of the tie rods.

11.0 Design Input This calculation uses the references of Section #3 as design inputs.
