Handwheel for valve 2AFOO5H is less than 1/8" from the actuator of valve 2AFOO5G. Piping is observed to be well-supported (lateral movement is limited and impact would be to rugged part of valve).IR 1396037 written documenting engineering review of the seismic movements.
Due to the relatively small displacements and the nature of the contact (hand wheel to air actuator) such contact will not result in valve assembly distortion that will challenge the function of the valve to open.8.

Per IR 1429477: "During Fukushima walkdown of valve 2CV1 12E to verify closure of an IPEEE outlier for clearance between operator of the valve and existing structural grating it was found that in the cold position there is a 0" gap between the valve operator and grating." The grating is in contact with the valve yoke however the valve is rugged and it is unlikely that damage would result from impact with the grating.IR 1429477 generated to address this issue.8.
