3D Printing Possibilities: Additive Manufacturing Impact Limiters for Transportation Casks
With the significant advances in additive manufacturing (AM), otherwise known as 3D printing, Orano Federal Services and the University of North Carolina at Charlotte recently re-examined the capabilities to print impact limiters for transportation casks used to ship spent nuclear fuel. Impact limiters protect transportation casks (sometimes also referred to as transportation overpacks) and their contents during an accident. Impact limiter designs must withstand testing based on a certain significance level of hypothetical accidents, including drops, crushing, fires, and immersion in water.

The 500-MW(electric) Prototype Fast Breeder Reactor (PFBR) is currently under construction at Kalpakkam, India. A core temperature monitoring system is provided to monitor adequacy of core cooling and protect the reactor against design-basis events. Triplicated real-time computer systems and hardwired systems are used for monitoring subassembly outlet sodium temperature and reactor inlet temperature. This paper describes the core temperature monitoring system provided in PFBR.
