Book Description
The High Performance Light Water Reactor (HPLWR) is a light water reactor with supercritical steam conditions which has been investigated within the 5th Framework Program of the European Commission. Due to the supercritical pressure of 25 MPa, water, used as moderator and as coolant, flows as a single phase through the core and can be directly fed to the turbine. Using the technology of coal fired power plants with supercritical steam conditions, the heat-up in the core is done in several steps to achieve the targeted high steam outlet temperature of 500 C without exceeding available cladding material limits. Based on a first design of a fuel assembly cluster for a HPLWR with a single pass core, the surrounding internals and the reactor pressure vessel are dimensioned for the first time, following the safety standards of the nuclear safety standards commission in Germany. Furthermore, this design is extended to the incorporation of core arrangements with two and three passes. The design of the internals and the RPV are verified using combined mechanical and thermal stress analyses and thermal-hydraulic analyses."

Book Description
The overall objective of this project is to evaluate the feasibility of supercritical light water cooledreactors for electric power production. The use of light water at supercritical pressures as the coolant in anuclear reactor offers the potential for considerable plant simplification and consequent capital and O & Mcost reduction compared with current light water reactor (LWR) designs. Also, given the thermodynamicconditions of the coolant at the core outlet (i.e. temperature and pressure beyond the water critical point), very high thermal efficiencies for the power conversion cycle are possible (i.e. up to about 45%). Because no change of phase occurs in the core, the need for steam separators and dryers as well as forBWR-type re-circulation pumps is eliminated, which, for a given reactor power, results in a substantiallyshorter reactor vessel and smaller containment building than the current BWRs. Furthermore, in a directcycle the steam generators are not needed. If no additional moderator is added to the fuel rod lattice, it ispossible to attain fast neutron energy spectrum conditions in a supercritical water-cooled reactor (SCWR). This type of core can make use of either fertile or fertile-free fuel and retain a hard spectrum to effectivelyburn plutonium and minor actinides from LWR spent fuel while efficiently generating electricity. Onecan also add moderation and design a thermal spectrum SCWR that can also burn actinides. The projectis organized into three tasks.

Book Description
The supercritical water-cooled reactor (SCWR) is one of the six reactor technologies selected for researchand development under the Generation IV program. SCWRs are promising advanced nuclear systemsbecause of their high thermal efficiency (i.e., about 45% versus about 33% efficiency for current LightWater Reactors [LWRs]) and considerable plant simplification. SCWRs are basically LWRs operating athigher pressure and temperatures with a direct once-through cycle. Operation above the critical pressureeliminates coolant boiling, so the coolant remains single-phase throughout the system. Thus, the need fora pressurizer, steam generators, steam separators, and dryers is eliminated. The main mission of theSCWR is generation of low-cost electricity. It is built upon two proven technologies: LWRs, which arethe most commonly deployed power generating reactors in the world, and supercritical fossil-firedboilers, a large number of which are also in use around the world. The reference SCWR design for the U.S. program is a direct cycle system operating at 25.0 MPa, withcore inlet and outlet temperatures of 280 and 500 C, respectively. The coolant density decreases fromabout 760 kg/m3 at the core inlet to about 90 kg/m3 at the core outlet. The inlet flow splits with about 10%of the inlet flow going down the space between the core barrel and the reactor pressure vessel (thedowncomer) and about 90% of the inlet flow going to the plenum at the top of the rector pressure vessel, to then flow down through the core in special water rods to the inlet plenum. Here it mixes with thefeedwater from the downcomer and flows upward to remove the heat in the fuel channels. This strategy isemployed to provide good moderation at the top of the core. The coolant is heated to about 500 C anddelivered to the turbine. The purpose of this NERI project was to assess the reference U.S. Generation IV SCWR design andexplore alternatives to determine feasibility. The project was organized into three tasks: Task 1. Fuel-cycle Neutronic Analysis and Reactor Core Design Task 2. Fuel Cladding and Structural Material Corrosion and Stress Corrosion Cracking Task 3. Plant Engineering and Reactor Safety Analysis.moderator rods.materials.
