EVALUATION OF CONTROL ROD MATERIALS CVTR PROJECT. Terminal Report

Technical Report ·
OSTI ID:4842785
Mechanical and corrosion tests were performed on various control rod materials for CVTR application. The corrosion tests were carried out in demineralized static-water at 190 deg F and in a helium-water vapor atmosphere at 530 deg F. The mechanical tests were carried out at room temperature and at 250 deg F. The tests indicated that either boronated stainless steel or silver-indium - cadmium alloy would perform satisfactorily in the CVTR environment. Based Primarily on the lower cost, boronated stainless steel was selected for the CVTR control rod. A prototype control rod was fabricated with boronated (1.5% B) stainless steel absorber material. The assembly was fabricated by riveting two absorber plates to AISI type 304 stainless steel center section. (auth)
