Prevention through surveillance and testing

Material surveillance activities may include irradiation of material coupons in normal operation conditions (e.g. reactor tank materials such as aluminium or reflector materials such as graphite or beryllium). These coupons can then be removed for testing without disturbing the component material itself. 

For those existing research reactors which require but lack such activities, irradiation in high neutron flux testing reactors may be appropriate. These surveillance and testing activities should be periodically reviewed following analysis of accumulated data.
