This paper summarizes a study of the implications of a technology-neutral regulation for advanced nuclear power plant designs and proposes a predominately rationalist approach to future nuclear plant regulations. The current body of regulations has been developed and evolved over the past 50 years with consideration of the knowledge and incidents experienced from operation of the Light Water Re...

This article discusses the optimization of the target motion sampling (TMS) temperature treatment method, previously implemented in the Monte Carlo reactor physics code Serpent 2. The TMS method was introduced in [1] and first practical results were presented at the PHYSOR 2012 conference [2]. The method is a stochastic method for taking the effect of thermal motion into account on-the-fly in a...

Materials and core components for the next generation power reactors technologies require testing that can be performed in existing research reactors. Such experiments employ devices dedicated to reflect relevant thermal neutron parameters simulating conditions present in, example, but not limited to, HTGR A novel thermostatic irradiation device named ISHTAR (Irradiation System High-Temperature...
