Clarification of the Requirements for Reactor Pressure Vessel Upper Head Bare Metal Visual Examinations

The U.S. Nuclear Regulatory Commission (NRC) is seeking public comment on a draft regulatory issue summary (RIS). The draft RIS informs all addressees of a clarification of the requirements for the bare metal visual examination. The draft RIS is relevant to all holders and applicants for a pressurized-water power reactor (PWR) operating license or construction permit, except those that have certified that they have permanently ceased operations and have permanently removed all fuel from the reactor vessel.
