-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 TypeⅠ (≦8000Bq/kg or) TypeⅡ (＜8000Bq/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: TypeⅠ and
TypeⅡ.
KEYWORDS：interim storage facility, specific activity in soil, Fukushima

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.
KEYWORDS：ITER, toroidal coil, welded 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：why-why analysis, quality assurance
