Guide 1.75Since WBN2 is not committed to RG 1.75 or IEEE-384, no comparison is required However, WBN2 is committed to RG 1.75 Rev. 2, Physical Independence of Electric Systems. RG 1.75 Rev. 3 and IEEE Std. 384-1992 are used, in part, to address IEEE Std 603-1991 Clause 5.6.1. The current NRC staff position for RG 1.75 is documented in Rev. 3.

(1) IITAs are not fully extracted and they are held in a movable frame assembly.
(2) IITAs exert lower vibration amplitude and therefore, aging degradation due to wear does not occur.
