Reactor Aspects of Fusion: Issues Related to Materials, Radioactivity and Radiation-induced Effects

A concise overview is given on materials applied in fusion technology. The influence of plasma operation on the behaviour of reactor components and diagnostic systems is discussed with emphasis on effects caused by fast particles reaching the reactor wall. Issues related to primary and induced radioactivity are reviewed: tritium inventory and transmutation. Tritium breeding in the reactor blank...

Radiation-resistant WDM Optical Link for Thermonuclear Fusion Reactor Instrumentation

The future International Thermonuclear Experimental Reactor (ITER) is a complex installation that will require permanent monitoring and frequent maintenance operations. The high-gamma dose rates, the high neutron fluence and other radiological hazards call for the use of remotehandled equipment. The management of heavy umbilicals connecting the control systems with the remote tools is therefore...

Radiation-induced Segregation and Void Swelling in 304 Stainless Steel

. Void swelling and radiation-induced segregation have been measured in 304 stainless steel. Samples were irradiated in the outer regions of the EBR-11reactor where displacement rates of 2.OX10-8and 6.6 xl 0-8dpds are comparable to those in pressurized water reactor components. Samples were inadiated at temperatures from 371-390°C to total doses of up to 20 dpa. Void swelling reached a maximum ...
