TL;DR: In this paper, the authors present an economic feasibility assessment of a high performance light water reactor (HPLWR) under the co-sponsorship of the European Commission and the University of Tokyo.

TL;DR: In this paper, the authors describe a core concept for a nuclear reactor cooled with supercritical water, in which the coolant is heated up from 280 °C at the reactor inlet to 500 Â c at the outlet in four steps: a first heat-up step is provided by heat transfer from fuel assemblies to the moderator water in gaps and moderator boxes, a second step is foreseen in a central "evaporator" and two further steps in a first and a second superheater surrounding it.

TL;DR: In this article, the thermal-hydraulic stability of a uniformly heated channel at supercritical water pressure has been investigated to help understand the system instability phenomena which may occur in super-critical water nuclear reactors (SCWRs).

TL;DR: In this paper, a detailed design of a fuel assembly of a high performance light water Reactor (HPLWR) has been presented, where the authors show that a square fuel assembly with two rows of fuel rods and a central moderator box is best to minimize the structural material, to optimize the moderator to fuel ratio and to reduce differences of fuel rod power.

TL;DR: The High Performance Light Water Reactor (HPLWR) as mentioned in this paper is a pressure vessel type reactor operated with supercritical water at 25MPa feedwater pressure and 500°C average core outlet temperature.
