AbstractAbstract
[en] The temperature monitors for fuel blocks in high temperature gas reactors during operation are being developed. The temperature monitors consists of alloy wires, with various melting points, sealed in quarts capsules. The temperature can be evaluated in the range from 600 to 1400degC with 22 types of the temperature monitors. The temperature monitors have been irradiated by the capsule in JMTR, and then, PIEs such as X-ray radiograph and EPMA have been carried out. As the results of the PIE, it was estimated that the temperature monitors can be used up to 90 days at 1100degC, or up to 50 days at 1300 - 1350 degC. (author)
