.I. Purpose Evaluate pressure integrity of lifferential pressure unit when subjected to combined operating and seismic loading.

II. Differential Pressure Unit Environment Design Loads (Reference 1)

Temperature = 500 F Pressure = 500 psig b Seismic Loads Maximum allowable g - level will be calculated.

III. Method of Analysis -

The most critical component affecting the pressure integrity of the unit is the bellows. The maximum allowable g-level for both horizontal and vertical directions is evaluated.

The remaining horizontal load is applied axially on the  !

l bellows. The g-level equivalent to one psig is computed to i show that any g-loads due to seismic events are negligible compared to the working pressure of differential pressure unit (500 psig, Reference 1)

Dimensions are scaled from References 2 and 3.

V. Maximum G-level Calculation (continued)

G-loads in the remaining axial direction can be considered negligible,. using the following rationale:

The g-level equivalent to 1 psig is g = 1 lb 1.625 H sq in 1 sq in 4 1.168(.1402) lb

= 12.66 This g-level of 12.66g corresponds to 0.2% of the working pressure. This indicates that g-loads applied axially to the bellows can be considered negligible.

VI. Natural Frequency

The frequency calculation will be made assuming both the' mass of the bellows and the shaft flex about either the shaft or the bellows. This is a conservative aporoach. The actual frequency will be 4t=-- - the two calculated below, per Ref 6.

VII. Conclusion The differential pressure unit bellows and shaft were judged to be the most critical comnonents affecting pressure integrity when the device is subjected to seismic disturbances. Natural fre-quency calculations showed the unit to be suf-fiently rigid to be well beyond the amplification range of normal nuclear piping sysYems. Maximum allowable g-levels were calculated resulting in levels well above exoccted ceak values. In conclusion, the differential pressure unit will maintain pressure integrity under the most extreme ~

seismic conditions.
