The Advanced Boiling Water Reactor-II (ABWR-II) is under development, based on the technologies and experiences of ABWR, to further improve the performance and economy. There are new systems and components developed or under development to incorporate into the primary system of ABWR-II. This paper introduces the primary system and ...

Two advanced boiling water reactors (ABWRs) whose electric output power is 1356 MW have been commercially operated since 1996 and 1997 by the Tokyo Electric Power Company (TEPCO) in Japan. Features of an ABWR are reactor internal pumps (RIPs) placed in the lower plenum and downcomer, peripherally bottom-mounted on the reactor pressure ...

1000 MWe Advanced Boiling Water Reactor has only two main steam lines and six reactor internal pumps, whereas 1350 MWe ABWR has four main steam lines and ten reactor internal pumps. In order to confirm how the differences affect hydrodynamic conditions in the dome and lower plenum of the reactor pressure vessel, fluid analyses have ...

This paper discusses the safety design of the Toshiba Boiling Water Reactor (TOSBWR) which was created {approx}8 years ago. The design concept is intermediate between conventional boiling water reactors (BWRs) and the advanced BWR (ABWR). It utilizes internal pumps and fine motion control rod drive, but the emergency core cooling system (ECCS) ...

It is possible to simplify the reactor internal pump power supply system in the ABWR without affecting the core flow supply when a trip of all RIPs event occurs by eliminating the motor-generator sets and increasing the rotating inertia of the RIPs. This inertia increase due to an additional flywheel, which leads to a gain in weight and length, requires a ...

The purpose of this paper is to provide the quantitative evaluation method with regard to the Digital Protection systems (DPSs) that were newly adopted in the ABWR plants and to show the results of level-1 PSA of the ABWR plants. (authors)

A fully implantable, axial flow blood pump has been developed in Fu Wai Hospital aiming for clinical use. This ventricular assist device (VAD), which was developed after numerous CFD analyses for the flow characteristics of the pump, is 58.5-mm long, 30-mm wide (including DC motor), and weighs 240 g. The pump can deliver 5 L/min for ...

This paper presents the model equations governing the nonlinear dynamics of the dispersive Alfv�n wave (DAW) in the low-? plasmas (?<pump DAW is perturbed by a ...

An innovative reactor core concept applying spectral shift rods (SSRs) is proposed to improve the plant economy and the operability of the 1700 MWe ABWR-II reactor. The SSR is a new type of water rod, in which a water level is naturally developed during operation and changed according to the coolant flow rate through the channel. By taking advantage of the largeness of the ...

The ABWR Design Verification Program is aimed at restoring confidence in the US licensing process by demonstrating its workability by obtaining USNRC preapproval of GE's ABWR Standard Plant. The purpose of this work is to achieve full NRC approval of the ABWR through the award of an NRC Staff final design approval (FDA) and ...

This report describes a plant model of the advanced BWR (ABWR) plant. The model has been jointly developed by CRIEPI and General Electric Company (GE). This model is designed for combining it with the CRIEPI power system dynamics analysis program and for ...

This paper describes an effort by Tokyo Electric Power Company (TEPCO) to shorten the construction time in a drastic manner for the Advanced Boiling Water Reactors (ABWR), thereby aiming at reducing construction costs. First an outline of the actual construction records for the five BWR Units and the two ABWR Units at the Kashiwazaki-Kariwa site is ...

A steam injector (SI) is a simple, compact and passive pump and also acts as a high-performance direct-contact compact heater to heat up feedwater by using extracted steam from the turbine. To develop high performance compact feedwater heater, it is necessary to quantify the characteristics between physical properties of the flow field. Its performance depends on the phenomena ...

The Na(+)-K(+)-ATPase is the primary electrogenic component driving transepithelial ion transport in the teleost gill; thus regulation of its level of activity is of critical importance for osmotic homeostasis. In the present study, we examined the dynamics of the gill-specific FXYD-11 protein, a putative regulatory subunit of the pump, in Atlantic salmon during seawater (SW) ...

We investigated the outcome of FW-II axial pump on healthy sheep (weight, 60-70 kg) for 2 weeks by perioperatively hematological and chemical tests, and circulating activated platelet and leukocyte-platelet aggregates measurements by flow cytometry assays. Complete necropsy and histopathological examinations and thorough pump ...

General Electric Company`s (GE`s) Advanced Boiling Water Reactor (ABWR) has been approved for operation in Japan, and the final design approval (FDA) by the U.S. Nuclear Regulatory Commission is scheduled for mid-1994. One possible utilization of the ABWR would be to operate with mixed oxide (MOX) fuel with the plutonium made available from the U.S. ...

The current Army Boiling-Water Reactor program is reviewed. Plant design, core analysis, reactor theory development, and health physics studies are discussed for the Portable Low-Power Plants (PL-1 and PL-2). Plans for installing a PL-2 plant in a snow tunnel at Byrd Station in Antarctica are described. (B.O.G.)
