Summary
A survey of literature on irradiation experience with boron stainless steel was conducted to determine the effect of neutron irradiation and boron-10 burnup on the two weight per cent natural boron stainless steel control rods being used in the Pathfinder reactor. The literature reviewed included irradiation test samples and full-size control rods in operating reactors. From the analysis of the survey, it was concluded that the Pathfinder control rods will operate satisfactorily and retain their integrity within the burnup limits prescribed. The effects of irradiation and boron-10 burnup on boron stainless were divided into the categories of mechanical properties, cracks, and swelling and gas release. These categories were examined in detail with the data available and correlated with the Pathfinder rods and operating conditions. The allowable local burnup of the boiler rods is limited to one core at.% (50% boron- 10 depletion) and the superheater rods are limited to one-half core at.% (25% boron-10 depletion). (auth)
