## Abstract

The NRC is amending its regulations governing vessel head inspection requirements. This amendment revises the upper range of the percentage of axial flaws permitted in a specimen set used for the qualification of nondestructive examination systems (procedures, personnel and equipment), which are used in the performance of inservice inspection (ISI) of pressurized water reactor (PWR) upper vessel head penetrations. This amendment is being made as a result of the withdrawal of a stakeholder's recommendation necessitated by a typographical error in the original recommendation with respect to the maximum percentage of flaws that should be oriented axially.
