International Conference on Topical Isues in Nuclear Safety
3 - 6 September 2001

Poster Session and Poster
In 1991, the IAEA organized an international conference on The
Safety of Nuclear Power: Strategy for the Future. Recommendations
from the 1991 conference prompted actions in subsequent years to advance
nuclear safety worldwide. One of those actions was the establishment
of the Convention on Nuclear Safety, which entered into force in October
1996. The first review meeting of the Conventions Contracting
Parties was held in April 1999. The meeting identified a number of
external factors and circumstances which could have a significant
impact on nuclear safety if they were not counteracted. These included:
(a) deregulation of electricity markets; (b) maintaining competence
in industry, regulators and research institutions; and (c) lack of
economic resources in some countries.
In 1998, the Agency held an International Conference on Topical
Issues in Nuclear, Radiation and Radioactive Waste Safety. The
nuclear safety issues discussed during the conference were: (1) safety
management; (2) regulatory strategies; and (3) backfitting, upgrading
and modernization of nuclear power plants. Senior nuclear safety decision
makers at the technical policy level reviewed these issues and formulated
recommendations for future actions by national and/or international
organizations. On the safety management issue, recommendations were
made to monitor safety performance by using indicators. Recommendations
on the regulatory strategies issue indicated the need for further
work on utilizing PSA and on optimizing the prescriptive nature of
regulations, as well as on the future availability of competent professionals.
Substantial progress has been made, and continues to be made by
Member States in enhancing the safety of nuclear power plants. At
the same time, more attention is being given to other areas of nuclear
safety. The safety standards for research reactors are being updated
and new standards are planned on the safety of other facilities in
the nuclear fuel cycle. It seems appropriate at this time to analyse
current topical issues and determine priorities for future work and
areas needing international consensus building.
The objective of the conference is to foster the exchange of information
on topical issues in nuclear installations safety, with the aim of
consolidating an international consensus on:
- the present status of these issues;
- priorities for future work; and
- needs for strengthening international co-operation,
including recommendations for future activities for the IAEA.
- THEMATIC SCOPE
Five current topical issues have been identified by the Conference
Programme Committee as subjects for technical sessions. Each topic
encompasses both general policy issues and more specific
technical issues. The topics and a selection of related issues are
Issue papers have been prepared in advance of the Conference to
provide an overview of each topic and the related issues. Further
information on the issues will be presented in the form of invited
keynote papers and contributed papers.
The Conference will cover the following main topics:
Issue 1: Risk-informed
decision making (

of external factors on safety (
- Pressures arising from economic deregulation and
competitive electricity pricing and their possible role in encouraging
or discouraging improved nuclear installation safety in the long
- Implications of political decisions on early closure
for the safety of nuclear installations.
- Role of the regulator in not unnecessarily hindering
the competitiveness of nuclear installations while ensuring that
safety margins are not eroded under these changing circumstances.
- Experience of utilities and regulators who have
been through or who are embarking upon these changes; lessons learned
in how to achieve a positive safety outcome while avoiding the obvious
- Downsizing utilities and/or regulatory bodies while
maintaining safety margins.
