Berkeley Scientists Pioneer Nanoscale Nuclear Materials Testing Capability

Lawrence Berkeley National Laboratory

Nuclear power is a major component of our nation’s long-term clean-energy future, but the technology has come under increased scrutiny in the wake of Japan’s recent Fukushima disaster. Indeed, many nations have called for checks and “stress tests” to ensure nuclear plants are operating safely.

In the United States, about 20 percent of our electricity and almost 70 percent of the electricity from emission-free sources, including renewable technologies and hydroelectric power plants, is supplied by nuclear power. Along with power generation, many of the world’s nuclear facilities are used for research, materials testing, or the production of radioisotopes for the medical industry. The service life of structural and functional material components in these facilities is therefore crucial for ensuring reliable operation and safety.

Now scientists at Berkeley Lab, the University of California at Berkeley, and Los Alamos National Laboratory have devised a nanoscale testing technique for irradiated materials that provides macroscale materials-strength properties. This technique could help accelerate the development of new materials for nuclear applications and reduce the amount of material required for testing of facilities already in service.
