The Supercritical Water-Cooled Reactor would operate at the critical point of water, giving it certain advantages over either pressurized or boiling water reactors.
Thus there was a need for a revised set of design and fabrication rules to facilitate the development of safe, economically competitive water-cooled reactors contained in pressure vessels.
Next in line are the eleven first-generation 440 megawatt VVER water-cooled reactors, notably at Kozloduy in Bulgaria.
The good safety record of inherently unsafe high-pressure water-cooled reactors has been achieved using expensive reinforced containment vessels, back-up cooling systems and a complex stringent regulatory system.
The company says this improves safety compared with conventional water-cooled reactors that run under pressure, leaving them liable to explosion.
Originally chosen to fit into the cramped confines of a submarine hull, water-cooled reactors are used today in most of the world's 440 operating nuclear plants.
The Prism reactor consumes transuranics in used nuclear fuel from water-cooled reactors, essentially turning plutonium waste into energy.
Samuel Untermyer then directed his focus toward the heat transfer of water-cooled reactors. The design constraint for pressurized water reactors was that there would be nucleate boiling or the formation of little steam bubbles on the surface of the fuel to enhance heat transfer, but no bulk boiling of the water.
