To consider effects of light water reactor coolant environments, new design curves included in report NUREG/CR-6909 NUREG/CR-6909c stainless steels and for low austeniticlstainlessen presteels.
Recent data indicate that the effects of light water reactor environments can significantly reduce the fatigue resistance of materials, and show that design fatigue curves may not be conservative for reactor coolant environments.
The number and orientation of the experimental trials, conducted in both dry and high pressure coolant (HPC) environments, were planned using full factorial design.
The main results of this study are that many thermo-physical properties of seawater are affected by changes in salinity of the coolant extracted from environment.
The reduction in, or the elimination of, in-cylinder heat transfer to either the coolant and/or the environment does not violate the second law of thermodynamics and, moreover, according to the first law, has the potential of producing more work.
The main findings of this study are that an increase of one degree Celsius in temperature of the coolant extracted from environment is forecasted to decrease by 0.444% and 0.152% in the power output and the thermal efficiency of the nuclear-power plant considered, respectively.
To be specific the dry and high pressure coolant (HPC) jet environments were explored as cutting conditions.
Some high value components require to be machined in a contamination-free environment, which means coolant cannot be applied during the machining.
