Numerical Simulation of Multi-Phase Flow with Chemical Reaction
Investigation of Sodium-Water Reaction in Steam Generator of Fast Reactor
FAPIG No. 170 pp.3〜6 (2005)

A numerical method of multi-dimensional, multiphase flow with chemical reaction, SERAPHIM code, has been developed to investigate a sodium-water reaction phenomenon which will be occurred in a steam generator of liquid sodium cooled fast reactor. With regard to sodium-water reaction model, the surface reaction and the gas-phase reaction models are taken into account based on a liquid and a gas phase of sodium respectively. A multi-fluid and one pressure model is applied to SERAPHIM code. It is demonstrated that one can investigate sodium-water reaction phenomena in detail.

KEYWORDS：multi-phase flow, computational fluid dynamics, fast reactor, steam generator, sodium-water reaction

High Temperature Gas-cooled Reactor Developments
for Hydrogen Production in the U.S.A.
FAPIG No. 170 pp.7〜11 (2005)

For electricity and hydrogen production, the advanced reactor technology receiving the most international interest is a modular, passively-safety version of the high-temperature, helium-cooled reactor referred to in the U.S. as the Modular Helium Reactor (MHR). Because of its ability to produce high-temperature helium, the MHR is well suited for a number of process-heat applications, including hydrogen production. Two hydrogen-production technologies have emerged as leading candidates for coupling to the MHR; (1) thermochemical water splitting using the iodine-sulfur (IS) process and (2) high-temperature electrolysis (HTE). This paper describes an update on conceptual designs being developed for hydrogen-production MHR.

KEYWORDS：high-temperature gas-cooled reactor, IS, HTE, hydrogen production, modular helium reactor

Development of New Entrance/Exit Processing System
Using EPD (Electronic Personal Dosimeter) with ID Card Reader
FAPIG No. 170 pp.12〜18 (2005)

Entrance/exit processing system in Shika Nuclear Power Station, Hokuriku Electric Power Company was upgraded in May 2004. In this new system, dosimeters with built-in ID card reading are used and make entrance/exit processing time shorter. Hereinafter describes this new dosimeters and entrance/exit management system.

KEYWORDS：dosimeters with built-in ID card reading, entrance/exit processing time shorter

Large Scale Nickel-metal Hydride Battery "Gigacell"
FAPIG No. 170 pp.19〜23 (2005)

Large scale nickel-metal hydride battery "Gigacell" is developed for industrial use as a power source and a energy storage. Nickel-metal hydride battery can charge and discharge at high rate, discharge most of energy stored in the battery with long life.
Nickel-metal hydride battery has no dangerous substance, toxic metal and welding so recycling of battery is safe and easy.
When using this battery for several kind of electric power generator we can obtain high total generating efficiency, for example, engine generator.

KEYWORDS：nickel metal hydride battery, Gigacell, charge, discharge generating efficiency, power source, energy storage, recycling

An Introduction of Contactless Palm Vein Authentication Technology
FAPIG No. 170 pp.24〜28 (2005)

The illegal drawer from the account by the skimming robber of the bank cash card of these days and outflow incident of the secret information & private information as a trigger, biometrics authentication catches a lot of publicity as the expedient which accurately does "personal identification".
The article explains the principle and the merit of "contactless-type palm vein authentication" which have promptly adopted by the financial system and have already widely spread, and introduces concerning the applied product and the application case.

KEYWORDS：biometrics authentication, personal identification, contactless-type palm vein authentication
