l 3.9.3.3 MAY 2 51982 In Section 3.9.3.3 of the SER, the staff stated that the applicant i
committed to provide its response to IE ButLetin 79-02 concerning the base plate flexibility effect.
We have reviewed the information on base plate flexibility described in the applicant's submittal dated April 14, 1982.
The applicant has described the i
method for calculating the Loads in the bolts due to the plate flexibility for various plate and bolt configurations.
The l
applicant also showed by means of numerical examples the effect of plate flexibility as compared to rigid plate analysis, and indicated the method for calculating the anchor factor of
[
l safety.
We find that the applicant's analysis satisfies the f
base plate flexibility requirements of IE Buletin 79-02 and is i
j acceptable.
