Information Notice No. 81-03:   CHECKLIST FOR LICENSEES MAKING 
                                   NOTIFICATIONS OF SIGNIFICANT EVENTS IN 
                                   ACCORDANCE WITH 10 CFR 50.72 

Description of Circumstances: 

Significant events reported to the NRC Operations Center receive prompt 
evaluation by NRC technical staff. To assure that adequate information is 
obtained for evaluation, in an expedient manner, checklists have been 
developed for the various types of events and are currently in use by the 
duty officers manning the NRC Operations Center. In an effort to communicate
to licensees the most useful types of information needed depending on the 
event, a combined checklist has been developed and is attached to this 
information notice. We recognize that this list is not all inclusive, nor 
are all of its sections applicable to each event. Rather, it is an attempt 
to list certain key data elements that, based on past experience, appear to 
suffice for the vast majority of notifications. Having this type of 
information available at the time of notification, or shortly thereafter, 
will serve to expedite the notification and evaluation process and make it 
more efficient. It is not intended that licensees complete the checklist 
prior to, or as a condition of, making a notification. Instead, the list is 
intended to inform licensees of the types of information about events that 
have been useful to the NRC. 

We solicit your cooperation in obtaining any other information that may aid 
NRC in understanding the event and request that you volunteer such 
information where appropriate. 

Recommendation to Licensees: 

This information notice is provided for general information to licensees. 
Recipients should review the information for applicability to their 
facilities. No specific action or response is requested at this time. 

If you have any questions regarding this matter, please contact the Director
of the appropriate NRC Regional Office.
