With the use of boron stainless steel in control rods in a reactor, it is important to know whether the operating conditions of temperature and radiation will effect changes in mechanical properties and dimensions and to know tbe magnitude of such effects if they occur. Tensile specimens of 18-8 stainiess steel containing 1% boron, enriched to 93% in boron-10, were fabricated and irradiated in the Materials Testing Reactor to 15 and 25% burnup of boron-10. These were tested for tensile strength, hardness, and elongation and examined metallographically to observe changes in microstructure. The irradiated material was extremely brittle, and areas that appeared to be vacancies were seen in the photomicrographs. (auth)
