Restructuring of Electric Power Industry in the U.S.
FAPIG No. 155 pp. 3`9 (2000)
Because of rapidly emerging deregulation and restructuring, the
electric
power industry in the U.S. is becoming increasingly diverse and
generates
many of new business entities, such as Power Marketer, Aggregator, ISO
and
RTO. gDot-comh companies could also be major contributors to
popularization of deregulation through internet. Various aspects of
restructuring in the U.S. electric power industry are described,
including
its history, such as PUHCA, PURPA. The difference in restructuring by
region
is also addressed. A question is whether the growth of competition and
deregulation would actually benefits customers.
KEYWORDSFthe U.S. electric power industry, deregulation,

Development of Volume Reduction System for Ion Exchange Resin Using
Non-thermal Inductively Coupled Plasma
FAPIG No. 155 pp. 10`19 (2000)
The amounts of radioactive spent ion-exchange resins are
increasing in the
water cleaning system in nuclear power plants.
The volume reduction technology has been required to reduce the
amounts of
spent ion-exchange resins for radioactive waste disposal.
We have been developed the volume reduction system for ion-exchange
resin
using the non-thermal ICP(Inductively Coupled Plasma).
The features of this system are following.
(1) High volume reduction is possible.
(2) This system is using non-thermal ICP, enabling very calm reaction,
which
reduces the scattered rates of radioactive particle to exhaust gas.
(3) The amount of exhaust gas is very little, leading the exhaust
treatment
equipment to be compact-size.

Structural Integrity Evaluation for HIP Bonded Fusion DEMO Reactor
Component
FAPIG No. 155 pp. 27`32 (2000)
@HIP(Hot Isostatic Pressing) is applicable to fabrication technology
for
in-vessel components of fusion DEMO reactor which has been fabricated
by
ferritic steel F82H. Verification of structural integrity of HIP
bonded
joint is one of the most important subjects on the development of
fusion
DEMO reactor component. Even now structural integrity evaluation
method for
HIP bonded joint is not enough estimated.
@This paper describes the results of low cycle fatigue test and
inelastic
analysis using HIP-element model under the bending load of
fusion DEMO
reactor. Low cycle fatigue strength and fracture/deformation mode has
been
obtained. SEM-observation was performed at the fracture surface of
HIP-element model and the bonded joints between cooling tubes and
plate were
inspected.
KEYWORDSFHIP, low cycle fatigue strength, in vessel components,

Seismic Proving Test of a Reinforced Concrete Containment Vessel (RCCV)
FAPIG No. 155 pp. 33`47 (2000)
This paper describes the results of a seismic test on a reinforced
concrete
containment vessel (RCCV) carried out using a large-scale,
high-performance
shaking table facility. The model used for the test is a scale
model of an
RCCV separated from the reactor building and consists of the shell
wall and
the steel liner fixed inside the shell wall. The direction of the
input
motions is horizontal and/or vertical. The behavior of the test model
under
seismic loading is estimated from the response waves, the maximum
response
values of the major components, load-deformation curves, and energy
absorption characteristics obtained in the test. The results
demonstrate
that an RCCV has superior seismic safety in the case of the assumed
earthquake excitation.
KEYWORDS : seismic test, reinforced concrete containment vessel, RCCV,
shaking table, shell wall, liner, input motion, horizontal, vertical,
maximum response, load-deformation curve, energy absorption, seismic
safety

Design Study of Handling and Storage System of Spent Target for
Neutron
Scattering Facility
FAPIG No. 155 pp. 48`54 (2000)
@A design study has been carried out on a basic plan, a
configuration, main
specifications and the arrangement for a handling and storage system
of the
spent target, moderator vessel and other components, which are highly
activated and contain the poisonous mercury, for the Neutron
Scattering
Facility so as to be treated remotely with high reliability and
safety.
@The system is composed of a vehicle to exchange the target, remote
handling equipments such as manipulators, casks to contain air-tightly
the
spent components, storage systems and so on.
@A computer simulation has also been performed to check the design
propriety, and it has been consequently proven that the safe and
highly
reliable system can be realized.
KEYWORDSFneutron scattering, target, spent target, remote handling,
radioactive material, storage system, computer simulation
