The Commission Policy.
t I.
Background.
Section 208 of the Energy Reorganization Act of 1974 (Public Law 93-J38.
42 U.S.C. 5848), as amended, required the Commission to submit to Congress each quarter a report listing for that period any A0s at or associated with any facility which is licensed or otherwise regulated pursuant to the Atomic Energy Act of 1954. as amended. or pursuant to this Act.
In a letter to the Senate Subcommittee on Oversight of Government Management. dated October 1.
1993, the NRC recommended to Congress a change in the A0 report publication frequency from quarterly to yearly. As a result. Senate 790. " Reports Elimination Act." Public Law 104-66 was signed by President Clinton on December 21. 1995. changing the A0 report to a yearly' publication.

3 For the purposes of Section 208 of the Energy Reorganization Act of 1974, as amended, an A0 is an unscheduled incident or event which the Commission has determined to be significant from the standpoint or public f
health and safety.
Each such report shall contain:
i (1)
The date and place of each occurrence:
4 (2)
The nature and probable consequence of each occurrence:
(3)
The cause or causes of each occurrence; and (4)
Any action taken to prevent recurrence.
The Commission also shall provide as wide dissemination to the public of,the information specified in clauses (1) and (2) of this section as reasonably possible within 15 days of its receiving information of each A0 and shall provide as wide dissemination to the public as reasonably possible of the information specified in clauses (3) and (4) as soon as such information becomes available, i
in July 1975, in the exercise of the authority conferred upon the Commission by Congress to determine which unscheduled incidents or events are significant from the standpoint of public health and safety and are reportable
)
to Congress as A0s, the Commission developed interim criteria for evaluating licensee incidents or events. On the basis of these interim criteria and as required by Section 208 of the Energy Reorganization Act of 1974, as amended, These the Commission began issuing quarterly reports to Congress on A0s.
4 reports,' " Report to Congress on Abnormal Occurrences," have been issued in NUREG-75/090 and NUREG-0090-1 through 5 for the period from January 1975 through September 1976. On the basis of its experience in the preparation and issuance of A0 reports, the Commission issued a general statement of policy that described the manner in which it would, as part of the routine conduct of its business, carry out its responsibilities under Section 208 of the Energy Reorganization Act of 1974, as amended, for identifying A0s and making the requisite information concerning each occurrence available to Congress and the public in a timely manner.
This general statement of policy was published in the Federal Reaister on February 24, 1977 (42 FR 10950) and provided criteria and examples of types of events that the Commission would use in determining whether a particular event is reportable to Congress as an A0.
The Commission has since refined this statement of policy on a number of occasions to reflect changes in regulation and policy. On the basis of these criteria, and as required by Section 208 of the Energy Reorganization Act of 1974, as amended, the Commission has issued quarterly reports to Congress on A0s since March l
1977. These reports, " Report to Congress on Abnormal Occurrences," have been
)
issued in NUREG-0090-6 through 10 and NUREG-0090, Volumes 1 through 18.
The Commission published a further revir. ion to the A0 policy statement and criteria in the Federal Reaister on December 19,1996 (61 FR 67072) to reflect changes in the Commission's policy and changes to the regulations.
In the Staff Requirements Memorandum dated November 7, 1996, SECY-96-193, approving this most recent revision to the A0 criteria the Commission directed the NRC
- Copies of NUREGs may be purchased from the superintendent of Documents. U.s, Government Printing i
office, (P.o. BOX 37082). Washington. DC 20402 9328. Copies are also available from the National Technical Information service, 5285 Port Royal Road, springfield. VA 22161. A copy is available for inspection and/or copying for a fee in the NRC Public Document Room. 2120 L street. NW (Lower Level). Washington. DC 20037.
5 staff to determine whether modifications to criteria III., "For Fuel Cycle Licensees." were necessary to explicitly include fuel cycle facilities that are not licensed but are otherwise regulated by NRC such as the gaseous diffusion plants.
The NRC staff evaluated the criteria applicable to fuel cycle facilities and has revised the criteria as follows:
A.
A0 criteria published December 19, 1996:
III.
For Fuel Cycle Licensees.
1.
A required plant shutdown as a result of violating a license condition or other safety limit.
2.
A major condition not specifically considered in the license that requires immediate remedial action.
3.
An event that seriously compromises the ability of a confinement system 'o perform its designated function.
B.
Revised A0 criteria to include gaseous diffusion plants:
Ill. For Fuel Cycle Facilities.
A shutdown of the plant or portion of the plant resulting from a 1.
significant event and/or violation of a law regulation, or a license / certificate condition.
J
l
~
i 6
2.
A major condition or significant event not considered in the j
license / certificate that requires immediate remedial action.
l 3.
A major. condition or significant event that seriously compromises the ability of a safety system to perform its designated function that requires immediate remedial action to prevent a criticality, radiological or chemical process hazard.
It is expected that as additional experience is gained, further changes in the criteria may be required.
Abnormal Occurrence Reporting The A0 statement of policy has been developed to comply with the legislative intent of Section 208 of the Energy Reorganization Act of 1974. as amended, to keep Congress and the public informed of unscheduled incidents or events which the Commission considers significant from the standpoint of public health and safety.
The policy reflects a range of health and safety concerns and is applicable to incidents and events involving a single occupational worker as well as those having an overall impact on the general public.
The policy statement contains criteria that include the reporting thresholds for determining those incidents and events that are reportable by NRC for the purposes of Section 208 of the Energy Reorganization Act of 1974 as amended.
The Commission has established the reporting thresholds at a c
1 I

7 level that will ensure that all events that should be considered for reporting to Congress will be identified. At the same time, the thresholds are generally at>ove the normal level of repoiting to NRC to exclude those events that involve some variance from regulatory limits, but are not significant from the standpoint of public health and safety.
i I
Licensee Reports This general statement of policy will not change the reporting requirements imposed on NRC licensees by Commission regulations, license conditions, or technical specifications (TS).
NRC licensees will continue to submit required reports on a wide spectrum of events, including events such as instrument malfunctions and deviations from normal operating procedures that are not significant from the standpoint of the public health and safety. but do provide data useful to the Commission in monitoring operating trends of licensed facilities and in comparing the actual performance of these facilities with the potential performance for which the facilities were designed and/or licensed.
Information pertaining to all events reported to the NRC will continue to be made available and placed in the public document rooms for public perusal.
In addition, the NRC publishes annual reports on events (NUREG-1272 series).
Information can also be obtained by writing to the U.S. Nuclear Regulatory Commission. Public Document Room. 2120 L Street.
NW. (Lower Level) Washington, DC 20555-0001, In addition, the Commission will continue to issue news announcements on events that seem to be newsworthy whether or not they are reported as A0s.

Those events reported by Agreement States that reach the threshold for reporting as an A0 are also polished in the " Report to Congress on Abnormal Occurrences."
2.
Definition of terms. As used in this policy statement:
(a) An " abnormal occurrence" means an unscheduled incident or event at a j
facility or associated with an activity that is licensed or otherwise regulated, pursuant to the Atomic Energy Act of 1954, as amended, or the Energy Reorganization Act of 1974, as amended, that the Commission determines to be significant from the standpoint of public health and safety; and 1
In addition to the criteria listed in Appendix A. section III, "For fuel Cycle facilities." which are applicable to licensees and certificate holders, such as the gaseous diffusion plants (GDPs). Other criteria of the policy statement which reference " licensees" or " licensed facility" or " licensed material" may also be applied to events at cert 1fied facilities such as the GDPs.

V.
Guidelines for "Other Events of Interest."
The Commission may determine that events other than.AQs may be of interest to Congress and the public and be included in an Appendix to the A0 report as "Other Events of Interest." Guidelines for events to be included in the A0 report for this purpose are items that may possibly be perceived by the i
' The wrong radiopharmaceutical as used in the A0 criterion for medical misadministrations refe any radiopharmaceutical other than the one listed in the written directive or in the Clinical p manual.
18 public to be of health or safety significance.
Such items would not involve a major reduction in the level of protection provided for public health or safety; therefore, they would not be reported as abnormal occurrences. An example is an event where upon final evaluation by an NRC Incident Investigation Team, or an Agreement State equivalent response, a determination is made that the event does not meet the criteria for an abnormal occurrence.
