Sir, 2 have the honour,to infore you that the Secretariat of the International Atomic Energy Agency is planning to hold a Technical Committee Meeting on Symptom-Oriented asergency Operating Procedures and Accident Management et the Agency's Headquarters in vienna from S-8 June, 1990.

is to ensure that procedures and guidance are available at approp for personnel involved in accident management.

Energency operating procedures (ROP) were extended, af ter the Three Mile' Island accident, to a wider range of accident conditions.

Procedures now being considered go beyond present klOPS to prevent or mitigate low probability events using operational modes and equipment that are not part of the normally used safety systems.

These.

extended procedures are sometimes called Accident Management Procedures (AMP) to distinguish them from normal 50Ps.

The basic objn tive of-the meeting, which is part of a series of scheduled meetings (9_ develop _a us9tle_ manual on accident management, is to.

exchange information on the status of the development of EOPs and AMPS'and to review the progress of their implementation.

Additional information about the meeting is provided in the attached

complicated situations and were primarily aimed at preventing melting of the i

i fuel in the reactor core.

r A primary objective for accident management is to further reduce the k

risks associated with severe core damage and the release of. radioactive material through the. effective use of plant personnel and hardware to prevent l

or mitigate severe accidents. To accomplish this objective, accident management procedures are needed to assist the operator in determining the proper actices to deal with low probability events that may lead to core melt, reactor vess.1 fa!!ure, and the releast of radioactive material. Although the relationship between the tops and the accident management procedutos may very from country to country, accident management procedures would 'entend beyond the scope of currently established BOPS.

The accident management procedures must be. closely interfaced with existing plant B0ps to ensure their success. Two options, which represent bounds on the range of potential options, are considered. the first option

'{

would be to implement accident management procedures as an extension of the E0Ps. The second option would be to maintain the accident annagement procedures separate from existing procedures. This separation would require that the conditions for transition from one procedure type to the other should be clearly defined and sufficient. training provided to sinimize the potential for human errors.

1 The approach used for accident management procedures would need to be

+

breed enough to adequately cover a wide spectrum of low probabillt) events.

I 3t is expected that this approach would follow the approaches used la recent i

sop development, that is, symptom oriented, function oriented, or state oriented approaches. Any of these approaches should be adequate for use for-the accident management procedures.

Development of the accident sanagement procedures.can be accomp!!shed in a three step process. The first step la to develop a technical basis which would require an understanding of the plant vulnerabilities and capabilities

+

and a selection of strategies to provide the necessary prevention or a

altigation. These strategies could be selected based on probabilistic considerations or on some combination of probabilistic and deterministic considerations.

Selected strategies must then be evtluated to identify the i

equipment and instrumentation involved and determine what actions by-operations personnel sust take place. The capacity for successful performance

{

4 of the equipment and the personnel actions must be assessed and means of resolving limitations identified.

The second step involves development of the procedures using the established technical basis. The means of developing' procedures may vary fros l
