requirements of the American National Standard Code for Pressure Piping,
ANSI B31.1, \"Power Piping\", except that any reference to table 136.4
shall be deleted. The examination method employed will be as prescribed
by the Sandia Delegated Representative (SDR). The SDR shall have the
right to inspect all welds by any nondestructive examination method of
choice or by removing welds and subjecting them to mechanical tests. The
inspection may be made during or after the weld has been completed. The
acceptance criteria for NDE will be as specified in B31.1 paragraph
136.4, under the NDE method used. The frequency of inspection shall be
as specified by the SDR but at a minimum 5% of welds will be inspected
with additional welds inspected at the discretion of the SDR if defects
