i 1

l A.

Item for which relief is requested:

I l

Circumferential piping welds listed in Relief Request Table B-11 (Page 2 of 18)

Il Item Code Class:

i 1

C.

Examination requirement from which relief is requested:

ASME Section XI 1983 edition, no addenda.

The requirement for volumetric exmnination of 100% of the weld length i

as described in Table IWB-2500-1, Examination Category B-J. Item Nos.

j B9.11 and B9.31.

D.

Basis for relief:

i The presence of certain physical restrictions and/or examination area geometries preclude the complete ultrasonic examination of the volumes l

required in Figs. IWB-2500-8,9 and 11 for those welds listed in Relief Request Table B-11. The required surface examinations have been completed with acceptable results, f

E.

Substitute examinations:

1 l

None - however, construction volumetric exam records available in l

permanent plant files supplement the partial exams performed to provide j

adequate assurance of the items structural integrity.

F.

Anticipated impact on the overall level of plant quality and safety:

j None l
