Feasibility Study of Supercritical Light Water Cooled Reactors for Electric Power Production

Status of Physics and Safety Analyses for the Liquid-Salt-Cooled Very High-Temperature Reactor (LS-VHTR)

“…The program was originally developed for thermal-hydraulic analysis of lightwater reactors and related experimental systems during loss-of-coolant accidents and operational transients. The code has recently been improved to simulate candidate Generation IV designs cooled by gas [Davis, 2005a], supercritical water [MacDonald, 2005], and lead-bismuth [MacDonald, 2002]. Thermo-physical properties of liquid-salt coolants have also been implemented into the code [Davis, 2005b], which allows it to simulate the LS-VHTR.…”

An Industrial Perspective on Environmentally Assisted Cracking of Some Commercially Used Carbon Steels and Corrosion-Resistant Alloys

“…Supercritical water oxidation (SCWO), [31][32][33][34][35] organic synthesis, [36][37][38][39][40][41][42][43][44] hydrogen production and upgrading of heavy crude oil, [45][46][47][48] and supercritical water reactor 49,50 have been proposed as SCW applications. As SCW applications tend to be under extremely high corrosive conditions (e.g., high temperature and high pressure, high or low pH, oxidizing or reducing environment, existence of chloride ion, etc.…”

“…For testing in the SCW environment, it is important to enhance the capability of testing EAC, as well as to generate reliable data in the environment up to 30 MPa of pressure and 600°C. [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] To achieve both high performance and extended component life for industrial applications, it is crucial to evaluate EAC resistance along with material development, component design, and manufacture processing. The root cause of failure and the key factors affecting the engineering life of components must be identified by testing not only small specimens but also component-level performance.…”

Safety analysis code SCTRAN development for SCWR and its application to CGNPC SCWR

“…A large number of investigations on the feasibility of SCWRs had been done in US, including the analysis of the passive safety system in an American concept of SCWR carried out by INEEL and Westinghouse (MacDonald et al, 2004). In order to avoid the risk of inadequate coolant flowrate in the loss of flow accident of the conventional SCWR, a high-pressure feedwater tank was placed between the main coolant line and the main steam line in the American SCWR to supply coolant when accidents occur.…”

“…The INEEL upgraded RE-LAP5-3D to carry out system analysis of SCWR. MacDonald et al (2004) modeled and analyzed the passive safety systems of the American SCWR concept with RELAP5-3D. CATHARE2 is an advanced version, which was extended based on the ''Best-Estimate'' system code CATHARE originally applied for PWR simulation in Europe, and was verified to own the ability to perform safety analysis of HPLWR (Antoni and Dumaz, 2003;Andreani et al, 2011).…”
