Significant events reported to the NRC Operations Center receive prompt evaluation by NRC technical staff. To assure that adequate infomation 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 consnunicate to licensees the most useful types of infomation 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, wiil serve to expedite the notification and evaluation process and make it more officient.
It is not intended that licensees complete the checklist prior to, or as a condition of, making a notification.
Instead, the list is intended ta 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 informa-tion where appropriate.
Reconsnendation to Licensees:
This information notice is provided for general infomation 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.
