Start Preamble

AGENCY:

Nuclear Regulatory Commission.

ACTION:

Notice of issuance.

SUMMARY:

The Nuclear Regulatory Commission (NRC) has issued NRC Bulletin 2003-02 to all holders of operating licenses for pressurized-water nuclear power reactors (PWRs) with penetrations in the lower head of the reactor pressure vessel, (RPV) except those who have permanently ceased operations and have certified that fuel has been permanently removed from the RPV. The NRC issued this bulletin to (1) advise PWR addressees that current methods of inspecting the RPV lower heads may need to be supplemented with additional measures (e.g., bare-metal visual inspections) in order to detect reactor coolant pressure boundary (RCPB) leakage, (2) request PWR addressees to provide the NRC with information related to inspections that have been or will be performed to verify the integrity of the RPV lower head penetrations, and (3) require PWR addressees to provide a written response to the NRC in accordance with the provisions of Section 50.54(f) of Title 10 of the Code of Federal Regulations (10 CFR 50.54(f)).

DATES:

The bulletin was issued on August 21, 2003.

ADDRESSEES:

Not applicable.
