We conducted a parametic analysis of stress-based and strain-based creep failure criteria to determine if there is a significant difference between the two criteria for SA533B vessel steel under severe accident conditions. Parametric variables includ

Since the accident at Three Mile Island Unit 2 (TMI-2), attention has focused on the conditions necessary for lower head failure under extreme temperatures and a range of system pressures. The focus of the present paper is on vessel response when an

With an increasing number of missions in space, cryogenic fluid supply systems become necessary as mission duration is extended. Most of the system operations involve multiple-phase phenomena. Accurate simulation of the operations is needed to predic

Previous studies of HeII heat exchangers have focused on tube-in-shell designs. The present paper examines the properties of a parallel flow HeII heat exchanger formed from two 254 mm lengths of copper channel having nominal rectangular dimensions 2

The central solenoid of the Compact Ignition Tokamak (CIT) is constructed from stacks of thick-turn, resistive pancakes. As the solenoid is operated at fields as high as 20 Tesla, it is desirable to determine accurately its non-axisymmetric response.

The central solenoid of the Compact Ignition Tokamak (CIT) must produce magnetic fields as high as 20 Tesla during a pulse. Axisymmetric analyses of the solenoid indicate the stresses experienced by the innermost turns at this field are approximately

A scoping study of a tokamak reactor fueled by a D-/sup 3/He plasma is presented. The Apollo D-/sup 3/He tokamak incorporates recent advances in high-field magnets (20 T) and utilizes rectennas to convert the synchrotron radiation directly to electri

This report evaluates both the positive and negative consequences of adding water to a degraded reactor core during a severe accident. The evaluation discusses the earliest possible stage at which an accident can be terminated and how plant personnel
