8011040260 IN 81-03 UNITED STATES NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT February 12, 1981 IE 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 intanded 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 informa-tion where appropriate.
Recommendation to Licensees:
This information notice is provided for general info-mation to licensees.
Recipients should review the information for applicsbility to their facilities.
No specific action or response is requested at this time.
If you have any questions regarding this matter, please contact the Dir1ctor of the appropriate NRC Regional Office.
