| 内容記述 | Beryllium intermetallic compounds (beryllides), are the most promising advanced neutron multipliers in demonstration (DEMO) fusion power reactors because of their low swelling and high stability at high temperatures. From the viewpoint of tritium production in beryllium/beryllides induced by several continuous reactions to neutrons, an application for use as a fuel as well as an appropriate management of tritium is of considerable importance. To simulate the high-temperature behavior of tritium, in this study, the desorption and retention properties of deuterium were investigated by evaluating deuterium ion implantation at high temperatures and desorption behaviors. As results of the desorption properties and retention of Be12V, deuterium implanted at high temperatures tends to easily desorb whereas Be12V has a considerably low retention of deuterium in the case of implantation at high temperatures. Moreover, the TEM observation proved that deuterium bubbles in Be12V implanted at R.T. and 573 K disappeared at annealing temperatures above 773 K, whereas deuterium bubbles in Be12V implanted at 773 K were not identified, indicating that the bubbles were generated but desorbed. |
