Addressees

nuclear power reactors. 

Purpose

The U.S. Nuclear Regulatory Commission (NRC) is issuing this information 
notice to inform addressees that the NRC has amended its regulations 
regarding the reporting of safety defects under Parts 21 and 50.55(e) of 
Title 10 of the Code of Federal Regulations (10 CFR Parts 21 and 50.55(e)), 
as published in the Federal Register (56 FR 36081) on July 31, 1991.  The 
changes became effective on October 29, 1991.  It is expected that 
recipients will review the information for applicability to their facilities 
and consider actions, as appropriate.  However, no specific action or 
written response is required.

Discussion

The 10 CFR Parts 21 and 50.55(e) final rules incorporate the Commission's 
experience with the existing regulations.  The final rules apply to the Com-
mission's licensees and to nonlicensees who construct facilities for, or 
supply basic components to facilities or activities licensed by the 
Commission.  

The major changes to the 10 CFR Parts 21 and 50.55(e) rules include the 
following: 

1.   Reduced duplication in reporting or evaluation among Parts 21, 
     50.55(e), 50.72, 50.73, and 73.71.

2.   Established uniform time limits for initial notifications and followup 
     written notifications for Parts 21 and 50.55(e).

3.   Established a time limit for transferring information from vendors to 
     purchasers or affected licensees for purposes of performing evaluations 
     of deviations and determining reportability under Part 21.

4.   Established a consistent definition of "defect" in Parts 21 and 
     50.55(e).

5.   Established consistent standards for the content of Parts 21 and 
     50.55(e) reports.
