Reactor Pressure Vessel Head Degradation and Reactor Coolant 
Pressure Boundary Integrity Issue

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of issuance.


SUMMARY: The Nuclear Regulatory Commission (NRC) has issued Bulletin
(BL) 2002-01 to all holders of operating licenses for pressurized-water 
nuclear power reactors, except those who have permanently ceased 
operations and have certified that fuel has been permanently removed 
from the reactor pressure vessel. It addresses the recent discovery of 
degradation in the reactor pressure vessel head at the Davis-Besse 
Nuclear Power Station and the concerns this has raised about the 
structural integrity of the reactor coolant pressure boundary 
throughout the pressurized-water reactor (PWR) industry. The purpose of 
the bulletin is to require PWR licensees to submit (1) information 
related to the integrity of the reactor coolant pressure boundary 
including the reactor pressure vessel head, at their respective 
facilities, and the extent to which inspections have been undertaken to 
satisfy applicable regulatory requirements, and (2) the basis for 
concluding that their plants satisfy applicable regulatory requirements 
related to the structural integrity of the reactor coolant pressure 
boundary and future inspections will ensure continued compliance with 
applicable regulatory requirements. This information is necessary to 
permit the assessment of plant-specific compliance with NRC 
regulations. The information will also be used by the NRC staff to 
determine the need for and to guide the development of additional 
regulatory actions to address reactor coolant pressure boundary 

DATES: The bulletin was issued on March 18, 2002.
