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.
