COMMUNICATION FROM THE COMMISSION TO THE COUNCIL
concerning an agreement between the European Atomic Energy Community 
represented by the Commission of the European Communities and nine 
other bodies for the regulation of the Abnormal Occurrences 
Report .ng System Association (AORSA)
C0MC85) 137 final

COMMUNICATION FROM THE COMMISSION TO THE COUNCIL
Concerning an agreement between the European Atomic Energy Community 
represented by the Commission of the European Communities and nine 
other bodies* for the regulation of the Abnormal Occurrences Reporting 
System Association (AORSA).
1. The Joint Research Centre at Ispra has developed and put into operation 
an "Abnormal Occurrences Reporting System (AORS)" as part of the Reactor 
Safety Programme approved by the Council (Council decision 22.12.83 - 
O.J. L3/21 5.1.1984).  Information regarding abnormal occurrences exists 
in the various national data banks which have been set up by the Parties 
to this agreement.
2. The AORSA will promote abnormal event data exchange between the Parties, 
collect information on occurrences that have or could have consequences 
for the safe operation of nuclear power plants, feed-back collective 
operational experience to the nuclear power plants, and encourage analyses 
of abnormal event data. The AORSA will set up a centralized data bank of 
abnormal occurrences based on information provided by the members of the 
association from the various national reporting systems. The potential 
benefits of this agreement for nuclear reactor safety research and 
development are considerable. It will ensure that data concerning safety 
related events which occur in the operation of nuclear power plants will
be freely exchanged between the members of the Association, and that all 
the relevant data will be combined to produce a comprehensive data base. 
This data base will provide a valuable resource for the various authorities 
concerned with nuclear safety.
3. The Commission informs the Council of its intention to conclude the 
attached agreement under the provisions of article 101 paragraph 3 
of the.treaty of the European Atomic Energy Community.

ANNEX 1
TO AGREEMENT N°
Technical provisions for the System*
1. Structure of the System
The System consists of independent National Data Banks of various national 
^  reporting systems, in which the original event data are stored.
In order to homogenize the reported data from these national reporting 
systems and to store the reported data directly coming from N.P.P.'s, also a 
Centralized Data Bank has been established.
2. Abnormal Event Reporting
2.1 Reporting Requirements.
The Members of the Association who shall supply data (Data Supplier) 
shall contribute to the System by means of :
- either the entire data file of their national reporting system, without 
reformatting and according to their reporting criteria;
- or data sets of pre-selected abnormal events from their national 
reporting systems, according to the "AORS" reporting criteria, as 
defined in point 2.4 below;
- or event data directly provided by the nuclear power plant in the form 
of their own event reports or directly on the "AORS" reporting format 
as in point 2.5 below.
2.2 Classification of information.
The data Suppliers are free to classify their events for a restricted users 
access.
These classified events will be secured in special Data Files by the use of 
keys. They will be accessable only to authorized Users as in point 3  below.
2.3 Updating
The data Suppliers shall update their data files in the System at least 
every six months.
2.4 Reporting Criteria
The abnormal events to be stored in the Centralized Data Bank are 
reported according to criteria as defined in Appendix no. 1  to this Annex.
These criteria can also be used for reporting by those national systems 
which do not contribute to the System by means of their entire data file.
Applying these criteria, an "average" reporting rate of 20 abnormal events 
per reactor per year is expected.
-  2 -

-  2 -
2.5 Content and Format
The System collects the abnormal events from all types of operating 
nuclear power plants and experimental nuclear reactors.
The information about the abnormal events to be stored in the 
Centralized Data Bank is specified in a reporting format as illustrated in 
Appendix no. 2  to this Annex.
2.6 Reporting Procedures
For each National Data Bank an informatie system and interrogation 
procedure has been set up for the storage and retrieval of its own event 
\ data content.
The input data for the Centralized Data Bank coming from the said 
national data banks and the event data directly provided by the N.P.P.'s 
are homogenized according to the following procedure :
- selection of abnormal events from the national data files according to 
the "AORS" reporting criteria (see point 2.4) above;
- transformation of the selected "abnormal events" reports into the 
"AORS" reporting format (see point 2.5 above), either on a voluntary 
basis directly by the data Supplier or otherwise by care of the General 
Secretary of the Association;
- transcoding and storage of the "abnormal events" data by means of the 
"AORS" computer format in the Centralized Data Base;
- verification of the selected and stored data, if requested, by the data 
Supplier concerned.
3. Users category
The Assembly shall decide on the "Users" category.
There are the following two categories of Users :
i
Category "A"
Users belonging to this category shall have access to both unclassified and 
classified information in the System.
Category "B"
Users belonging to this category shall have access only to unclassified 
information in the System. They may, however, ask authorization for access to 
the classified information in accordance with the provisions of the Standard 
Contract (Annex no. 2) to this Agreement.

APPENDIX N° 1  TO ANNEX N° 1
TO AGREEMENT N°
Reporting Criteria
For reasons of coordination of the System with the Incident Reporting System (IRS) 
< ^ > f  the NEA, the reporting criteria for the IRS have also been taken as a basis for 
the selecting and reporting criteria of the "AORS" Centralized Data Bank.
The difference between the IRS and the AORS finds expression in the extent of 
reporting: in the case of the IRS only "significant" events will be reported with an 
average rate of 1 incident per reactor/year, whilst the AORS aims at a much more 
extensive reporting (about 20 events per reactor/year).
The "AORS" reporting criteria are defined, and illustrated with examples, as 
follows:it
1. Release of, or Exposure to, Radioactive Material 
Examples include :
an event that results in release of radioactive material to the 
environment;
‘  - an event that results in a member of the public receiving a radiation dose;
an event that results in facility personnel receiving a radiation dose.
2. Degradation of Safety-related Systems
2.1 Fuel cladding failure.
Examples include :
- fuel cladding failures requiring plant shutdown;
- cladding failures in spent fuel in the storage pond.
2.2 Degradation of the primary coolant boundary, main steam or feedwater 
line.
Examples include :
- through-wall failures of the piping or the components of the primary 
coolant circuit;
- welding defects or material defects in the primary coolant circuit;
- rapid temperature or pressure transient exceeding the authorized 
limits;
- loss of relief and/or safety valve functions during tests or operation.
-  2 -

-  2 -
2.3 Loss of containment function or integrity.
Examples include :
- containment leakage rates exceeding the authorized limits;
- loss of containment isolation valve functions during tests or operation;
- loss of main steam isolation valve functions during tests or operation;
- loss of containment cooling capability.
2.4 Degradation of systems required to control criticality.
,  Examples include :
- failures of the Control Rod System;
- accidental criticality,
- failures of the Boron Injection system
2.5 Degradation of systems required to control the system pressure or 
temperature.
Examples include : j
- failures of the Emergency Core Cooling Systems such as the High/Low 
Pressure Core Injection System and the Core Spray System;
- loss of core cooling ability including failures of the Residual Heat 
Removal System;
- loss of Auxiliary Feedwater System.
2.6 Loss of essential support system.
Examples include :
- loss of AC/DC power;
- failures of the Emergency Generator System;
- loss of service water, air, gas, etc.
3. Deficiencies in Design, Construction, Operation or Evaluation with regard to 
Safety
Examples include :
deficiencies in design or construction which, if incorrected, could result in 
the loss of a required safety function;
personnel errors or procedural deficiencies which result in loss of plant 
capability to perform essential safety functions;
discovery of a major condition not specifically considered in the 
authorized limits or previously analysed.
4. Generic Problems of Safety Interest 
Examples include :
series of events where individual events are not of significant importance; 
recurring events;
events with implications for similar facilities.
- 3 -

- 3  -
5. Consequential Actions
Consequential actions resulting from reported events taken by the competent 
safety authority on licensing, design or operation.
6. Events of Potential Safety Significance
Events which have no direct consequences but may be considered as 
approaching "near-misses".
i
7· Effects of Unusual External Events Either of Man-made or Natural Origin 
Examples include :
an earthquake exceeding the safe shutdown earthquake; 
a flood exceeding the safe shutdown flood; 
an aircraft crash on a nuclear facility.
