SM-1 REACTOR VESSEL CLOSURE STUD INVESTIGATION
Metallurgical analyses and corrosion tests conducted to determine causes of failure of two SM-1 reactor vessel studs due to fracture in the threaded areas, after 23 months' operation (March 1959) are described. It was concluded that failure of the studs was caused by stress corrosion cracking. Contributing factors to failure of the studs were improper control of heat treatment of the studs and absence of treatment for stress relief after thread grinding operation (auth)
