l ITEM 46 With respeec to Question 220.20 provide typical results of the analysis ch fluid structure interaction based on the 3 approaches discussed.

Response

As reported in our previous response, results from the concentrated ma s model show higher accelerations overall than either the fluid element model or.the Sloshing-mass model. These results are shown in the attached tatic. 'The nodes refer to the model shown in Figure 3A-1 of Appendix 3A of the Perry FSAR. In general, the two components of acceleration listed for Concentrated Mass Model results are higher, thus showing conservation in accelerations when this method is used. j COMPARISON OF ACCELERATIONS (FLUID ELEMENT, SLOSHING MASS, CONCENTRATED MASS) (IN/SEC ) X-Direction (Radial) Y-Direction (Vertical) Node Number Fluid Sloshing Concentrated Fluid Sloshing Concentrated 7 79.55 72.34 96.03 189.68 101.08 173.39 13 17.88 22.49 21.12 164.77 89.49 149.23 24 166.01 177.11 237.29 67.39 56.88 81.35 a e O J _ _ . . - , , - .m . .- m_- _ m_,. _

ITEM 48 Provide the method and justification that 2 directional spring used for a unidirectional rope does not significantly affect the analysis of the polar crane.

Response

The seismic analysis of the polar crane system uses a linearly elastic two-dimensional spring to model the suspended design lifted load. Use of a linearly elastic spring provides more conservative response than use of a unidirectional, tension only, spring. The two-dimensional spring allows seismic harmonic amplification to occur, while a unidirectional only spring ceases amplification as soon as the seismic load direction is reversed. The polar crane analyses (I) considers (frequency and magnitude) 3 lifted load positions : high, intermediate, low; and 3 trolley positions : center span, quarter span and end span; for a total of 9 separate analyses. Justification. i. provided, therefore, by using a more conservative practical approach using linearly elastic methods, rather than a more accurately modeled non-linear method.
