Water reactors represent a high level of performance and safety. They
are mature technology and they will undoubtedly continue to be the main
stream of nuclear power. There are substantial technological development
programmes in Member States for further improving the technology and for the
development new concepts in water reactors. Therefore the establishment of
an international forum for the exchange of information and stimulation of
international co-operation in this field has emerged.
In 1987 the IAEA established the International Working Group on
Advanced Technologies for Water-Cooled Reactors (IWGATWR). Within the
framework of IWGATWR the IAEA Technical Report on Status of Advanced
Technology and Design for Water Cooled Rectors, Part I: Light Water Reactors
and Part II: Heavy Water Reactors has been undertaken to document the major
current activities and different trends of technological improvements and
developments for future water reactors. Part I of the report dealing with
LWRs has now been prepared and is based mainly on submissions from Member
States, and the Agency would like to thank all those individuals and
institutions who have contributed to it. In particular the Agency would
like to express its gratitude to the consultants, (see attached list) who
continuously reviewed the progress of the report and thus contributed
substantially to its successful completion. Thanks are also given to the
secretaries from the Agency's Division of Nuclear Power, who devoted to the
typing of the report.
It is hoped that this part of the report, containing the status of
advanced light water reactor design and technology of the year 1987 and
early 1988 will be useful for disseminating information to Agency Member
States and for stimulating international cooperation in this subject area.
Part II of the report dealing with HWRs is in preparation with release
expected during 1989.
