... This paper presents equations for the limit pressure of a cylindrical vessel with a longitudinal crack. The calculations are based on a log-spiral slip-line and plane-strain conditions. The calculated limit pressure is compared with the pressure measured in the Pressurized-Thermal-Shock...

... Thermal shock damage may be a precursor to the melting and disordering of metallic reflector surfaces. A number of investigators have reported in these proceedings the phenomena of slip fracture on the surfaces of both polished and diamond turned optics. In this paper, a model is presented using...

... Flaw behavior trends associated with pressurized thermal shock (PTS) loading of pressurized water reactor (PWR) pressure vessels have been under investigation at Oak Ridge National Laboratory (ORNL) for approximately twelve years. During that time, eight thermal shock experiments with thick...

... presently are required to meet. Therefore, the unit under investigation was subjected to the most severe conditions that might be experienced by clay flue liners such as thermal shock, creosote burnout, and extremely high flue gas temperatures. Test results showed that at present the unit would not pass...

... Susceptibility of salmonids to the fish pathogen, Flexibacter columnaris , was used to assess sublethal stress following exposures to two environmental stressors, thermal shock, and suspended volcanic ash. Juvenile rainbow trout ( Salmo gairdneri ) were more susceptible to disease following...

The specimens were also bottom-flooded under a nonrestrained condition to determine the effect of restraining stress on thermal-shock-failure characteristics. The presence of restraining stress limits the permissible oxidation...

... The recent definition of a postulated thermal shock accident followed promptly by system repressurization, termed an overcooling or pressurized thermal shock accident , has set a large analysis and research effort into motion. The essential elements are concerned with defining the accident...

... This paper presents evaluations of the onset of fracture and crack arrest in a thick-walled A508 steel cylinder (530-mm outside diameter, 240 mm inside diameter and 910 mm long) for thermal shock loading conditions similar to those postulated for a nuclear reactor vessel. The evaluations include...

... To establish the mechanical response of Zircaloy cladding under thermal shock conditions typical of hypothetical loss-of-coolant accident (LOCA) situations in light-water reactors (LWRs), cladding specimens were ruptured in steam during transient heating (10 K/s), oxidized at maximum...

... This paper illustrates a procedure for estimating the stress intensity factors of a semi-elliptical surface crack in a thermally shocked thick plate. The first step in this procedure is to calculate the time-dependent thermal stresses induced by sudden cooling of an uncracked plate by using...
