P Subsections Affected Impact No. DRAFT Rev. 3 - April 1996 3.10-32 270 Revise Acceptance Criteria subsection to address No changes were made to SRP common design and analysis practices with regard to Section 3.10 based on this stiffness of anchorage of heavy equipment. Generic Integrated Impact. The generic Issue 146 indicates that it is "common industry issue that identifies this concern is practice" to assume rigid attachments between yet to be resolved. It also appears equipment and supports, and this assumption may that the guidance contained in be nonconservative. Subsections II.1.a(7) and (8) generally covers this concern. 271 Delete reference to ANSI B.16.41 (draft). No changes were made SRP Section 3.10 based on this Integrated Impact.

See Integrated Impact No. 267. 272 Revise Review Procedures section to incorporate No changes were made to IEEE Std 382-1985 in place of ANSI N41.6 (draft) SRP Section 3.10 based on this Integrated Impact. See Integrated Impact No. 1490. 273 Limit stresses in valve bodies and pump casings to ACCEPTANCE CRITERIA, the elastic limit for SSE in combination with normal II.1.a(9) operating loads and other dynamic loads 653 SRP Section 3.10 cites ANSI N278.1 1975. The REVIEW PROCEDURES, cited version was redesignated and reaffirmed in Subsection III. 1992. Consideration should be given to citing the reaffirmed version of this standard.
