Development of Survey Meter Series
FAPIG No. 180 pp.9 to 14 (2010)

Three types of radiation survey meter going on sale by Fuji Electric Co. recently are introduced in this article. Neutron survey meter has been reduced the weight down to a quarter due to development of mixed organic gas detector without moderator. Wide energy range survey meter has been made possible to measure X-ray which energy is 8keV or more by using a thinned window of the detector and G function. Semiconductor survey meter, for surface contamination measurement of alpha and beta rays, has reduced in size and weight and it's uniformity of detection efficiency has improved by using silicon semiconductor sensors instead of a previous model.

KEYWORDS：survey meter, neutron survey meter, light weight neutron survey meter, wide energy range survey meter, g- function, contamination survey meter, silicon semiconductor sensor, efficiency

Replacement Circuit Breakers by Retrofitting of 7.2kV 63 kA TCB to VCB Development
FAPIG No. 180 pp.15 to 20 (2010)

Fuji Electric has maintained the facility of 6.9kV metal-clad switchgear at Tokai-? Power Station, through periodic inspections since the first operation. Responding to the fact that the maintenance parts of the circuit breaker are becoming exhaustive, we developed two types of vacuum circuit breakers in order to promote the replace for minimal oil circuit breakers (TCB). This paper presents the development process and outline of the retrofitting VCB.

KEYWORDS：vacuum circuit breaker, VCB, metal-clad switchgear, TCB

Fuels and Materials Irradiation Test Plan at JMTR
FAPIG No. 180 pp.22 to 25 (2010)

Refurbishment of Japan Materials Testing Reactor (JMTR) is conducted in Japan Atomic Energy Agency (JAEA) in order to solve irradiation rerated issues for safe long-term operation of current light water reactors (LWRs) and development of advanced LWRs. JMTR will restart its operation in FY 2011. Manufacturing and installation of the irradiation test facilities on safety research of fuels and materials are also in progress. The outline of the fuels and materials irradiation test plan is described in this report.

KEYWORDS：light water reactor, nuclear fuels, nuclear materials, fracture toughness, stress corrosion cracking, irradiation technology, JMTR

Development of Integrated Small Hydropower Equipment
FAPIG No. 180 pp.26 to 29 (2010)

Small hydropower is renewable energy that generates power from unexplored hydraulic energy, and does not discharge carbon dioxide.
Kawasaki Plant Systems' integrated hydroturbine incorporating a generator is of compact construction less than half the size of a conventional hydroturbine for small hydropower generation. This hydroturbine employs a water-lubricated bearing that is totally oil free, thus realizing environment friendly, clean power generation with no noise, vibration.
Kawasaki Plant Systems provide a lineup of integrated hydroturbine models ranging from 20 to 500 kW.

KEYWORDS：compact construction, water-lubricated bearing, no noise, vibration

Development of the New Maintenace Management System for MONJU
FAPIG No. 180 pp.30 to 35 (2010)

Prototype fast breeder reactor in Japan Atomic Energy Agency "MONJU", the aim of strengthening the safety and reliability of maintenance management, maintenance management system from client-server system of updating the Web system. Fiscal 2008 the Web system started a new maintenance management systems approach. In this paper, we introduce the features and functions of the new maintenance management system.
