(a) The consideration of advanced designs is especially important to the future of the nuclear power industry. Advanced reactors in general have the following goals:

— Satisfying stringent safety requirements (e. g. by use of a combination of both active and passive safety systems),

— Improving the economics of power generation

(b) TCM participants concluded that additional analytical and experimental work is highly recommended both for the development of new, and the validation of current, computer codes. Basic research in natural circulation phenomena could help to improve codes and design capabilities. In addition, large-scale tests of natural circulation systems could provide direct substantiation of their functioning under the real plant conditions;

(c) The papers presented to this TCM show that a large scope of analytical and experimental investigations has been performed and are being planned in Member States in relation to natural circulation systems and equipment.
