-Outline and Construction Status of the Demonstration HTGR Program (HTR-PM) of China
FAPIG No. 188 pp.3 to 8 (2014)

The report provides the outline and construction status of the High Temperature Reactor - Pebble- Bed Module (HTR-PM) demonstration plant developed in the People's Republic of China. The development program of HTR-PM is now under progress based on the experience of the construction and operation of the test reactor HTR-10. The construction of the HTR-PM started in December, 2012 and expects to achieve operation in 2017.

Development of the Equipment for Measuring Specific Activity of Gamma-emitting Radionuclides in Soil
FAPIG No. 188 pp.9 to 15 (2014)

A large volume of contaminated wastes including the soil in the various grounds, plants, the sludge and so on, which were collected by the decontamination process after the accident at the Fukushima Daiichi NPP in 2011, have been placed at temporary storage sites in Fukushima Prefecture.
In order to store and manage the wastes safely and intensively until the final disposals are carried out, it is planning to construct the interim storage facilities.
When the facilities accept the wastes, they are planning that the wastes will be categorized as either Type‡T (…8000Bq/kg or) Type‡U (ƒ8000Bq/kg) and then will be disposed in accord with the category.
Fuji Electric and SHIMIZU CORPORATION have jointly developed the equipment coupled with automatic and sequential batch process, which measures specific activity of the soil with high accurate total error within }20% and then separates the soil into two different types: Type‡T and Type‡U.

Introduction about Development for Manufacturing of Structure for ITER Troidal Field Coil
FAPIG No. 188 pp.16 to 19 (2014)

Japan is assigned the procurement of the toroidal coil for the toroidal magnetic field generation in ITER project. The procurement agreement is advanced and about half of all the 19 sets has completed.
We has performed establishment of the welding technology for the manufacturing and inspection technique for the structure of troidal field coil using the special steel applied by this apparatus with Japan Atomic Energy Agency and Toshiba Corporation. In this paper, it is shown the activity of research and development about the manufacturing technique for the concrete form specification of troidal field coil structure.

Introduction of the Activity of the Quality Assurance Section
- Introduction of the Reference Book of the Why-Why Analysis -
FAPIG No. 188 pp.19 to 24 (2014)

The policy of the quality assurance section of FAPIG is that an investigation collects domestic and foreign new trends or valuable information which contributes quality assurance and the quality control of the member of FAPIG.
In addition, for the purpose of modification and improvement of the quality assurance activity of the quality control in the actual business of FAPIG companies, our section has been practicing with exchanging information mutually.
In the activity during 2011 to 2012 fiscal year, our section drawn up the reference book which gathered up a point of why-why analysis.
This report introduces the contents of the reference book of the why-why analysis as activity of the quality assurance section mainly.

KEYWORDSFwhy-why analysis, quality assurance
