(The American Society of Mechanical Engineers (ASME), 2017)In the National Aeronautics and Space Administration (NASA) Design Reference Architecture 5.0 (DRA 5.0), fission surface power systems (FSPS) are described as “enabling for the human exploration of Mars.” This study ... -
The Standard for Radiation Protection of the IAEC as a Model for a Revision of the Legal Framework for Radiation Safety in Israel
(The American Society of Mechanical Engineers (ASME), 2017)In Israel, a single regulatory body for radiation protection does not exist. Instead, its responsibilities and functions are shared between five government ministries and agencies. Accordingly, the existing legal framework ... -
Development of Kinetic Models for the Long-Term Corrosion Behavior of Candidate Alloys for the Canadian SCWR
(The American Society of Mechanical Engineers (ASME), 2017)Corrosion behavior of Inconel 625 and Incoloy 800H, two of the candidate fuel cladding materials for Canadian supercritical water-cooled reactor (SCWR) designs, was evaluated by exposing the metals to supercritical water ... -
A Review of Safety Analysis Philosophies for Nuclear Reactors
(The American Society of Mechanical Engineers (ASME), 2017)Various questions can be examined when discussing safety in general. Among these, some key issues are the attitude toward risk and its acceptance, the ways of identifying, analyzing, and quantifying risks, and societal ... -
Thermo-Economic Performance of a Cogeneration Medium–Small Modular Nuclear Reactor Plant in Canada
(The American Society of Mechanical Engineers (ASME), 2017)Hitachi-GE developed a 300 MWel class modular simplified and medium small reactor (DMS) concept, and the DMS was originally designed for generating electricity only. In this study, the feasibility of a cogeneration DMS ... -
Resistance Improvement of Aluminum Surface to Corrosion Through Reactions With Fluoride Ions
(The American Society of Mechanical Engineers (ASME), 2017)The reaction of fluoride ions with alumina was found to strongly depend on the concentration of fluoride ions in the aqueous solution. At low concentrations ([fluoride ions] < 0.1 mol/l in the case of potassium fluoride), ... -
Influence of Boundary Conditions, Vessel Geometry, and Simulant Materials on the Heat Transfer of Volumetrically Heated Melt in a Light Water Reactor Lower Head
