Head of Project, in charge of the coordination of Research and
Development programs related to instrumentation for research reactors
in the Nuclear Energy Division of CEA.
Initiator and now coordinator of the Joint Instrumentation Laboratory

In charge of the development of in-pile measurement systems for the
future Jules Horowitz Reactor (JHR) which will start operation in
Cadarache in 2014.
Abstract:
If nuclear energy has definitely reached its maturity, it is still
facing challenges. In particular, the assessment of material and fuel
behaviour under radiation still requires support, and a continuous
effort has to be followed to improve upstream research programs from
“cook and look” irradiations toward highly instrumented experiments.
In the present context of nuclear renaissance, optimizing the life
cycle of nuclear systems under safety constraints requires
high-performance experimental programs to reduce the existing
uncertainties on margins and limits.
In addition to improvement in modelling and simulation, innovation in
instrumentation is crucial for analytical and integral experiments
conducted in research reactors. These needs are particularly critical
in Material Testing Reactors (MTRs), which are specifically dedicated
to the assessment of nuclear radiation effects on material or fuel
sample properties. Irradiations carried out in MTRs are essential
phases in most scientific programs regarding nuclear technologies, such
as research for the enhancement or qualification of nuclear fuels for
current or future power reactors, the assessment of reactor materials
ageing for lifetime increase studies, and in-pile tests of innovative
devices for advanced reactors or material investigations.
The quality of nuclear research programs relies obviously on an
excellent knowledge of their experimental environment which constantly
calls for better online determination of neutron and gamma flux. But
the combination of continuously increasing scientific requirements and
new experimental domains –brought for example by Generation IV
programs- necessitates also major innovations for in-pile measurements
of temperature, dimensions, pressure or chemical analysis. For these
reasons, significant efforts have been made recently in order to
strengthen research and development activities regarding innovative
reactor instrumentation.
However, the integration of online measurements in nuclear reactors
meets strong constraints that can be illustrated by the following
criteria:
- high reliability, because irradiated sensors cannot be replaced or
repaired easily;
- very high accuracy, in order to satisfy continuously increasing
scientific requirements;
- capability to operate in harsh nuclear environments (neutron flux and
gamma radiation in MTRs can exceed respectively 4∙1018 n∙m-2∙s-1 and 15
kGy∙s-1);
- capability to operate in corrosive environments, such as pressurized
water, liquid metals, or high-temperature gas;
- miniaturized sensors and cables in order to ensure a low
intrusiveness, for instance when needed to be implemented in narrow
irradiation devices without altering the nominal thermal conditions of
the samples;
- safety management, involving redundancy and specific data analysis.
As a result, reactor instrumentation can somehow appear as a very
conservative area where progresses need much time before being
considered as proven technology and included in the operational
practice.
Nevertheless, major progresses have recently been obtained in this
field, such as implementation of optical and acoustical techniques in
research reactors.
The main constraints encountered to integrate instrumentation in
nuclear reactors will be described. An overview of the state-of-the-art
and upcoming innovations for reactor measurements will also be proposed.
Key Words: reactor instrumentation, nuclear measurements, optics,

(16:15-17:15)
A critical
look at Model-Driven Engineering for complex (robot) control systems
Herman Bruyninckx
(Katholieke Universiteit Leuven, Department of Mechanical
Engineering, Belgium )
Dr. Bruyninckx (<http://people.mech.kuleuven.be/~bruyninc/>)
obtained the Masters degrees in Mathematics (Licentiate, 1984),
Computer Science (Burgerlijk Ingenieur, 1987) and Mechatronics (1988),
all from the Katholieke Universiteit Leuven, Belgium. In 1995 he
obtained his Doctoral Degree in Engineering from the same university,
with a thesis entitled ``Kinematic Models for Robot Compliant Motion
with Identification of Uncertainties.''
He is full-time Professor at the K.U.Leuven, and held visiting research
positions at the Grasp Lab of the University of Pennsylvania,
Philadelphia (1996), the Robotics Lab of Stanford University (1999),
and the Kungl Tekniska Hogskolan, Stockholm (2002). Since 2007, he is
Coordinator of the European Robotics Research Network EURON (<http://www.euron.org>).
His current research interests are on-line Bayesian estimation of model
uncertainties in sensor-based robot tasks, kinematics and dynamics of
robots and humans, and the software engineering of large-scale robot
control systems. In 2001, he started the Free Software ("open source")
project Orocos (<http://www.orocos.org>),
to support his research interests, and to facilitate their industrial
exploitation.
Bayesian estimation is his core research activity, and has its focus on
"realtime" design: the raw sensor measurements must be processed and
interpreted in the context of the motion and interaction models fast
enough in order to use them in the feedback control of the robot. The
sensors and models used in the "interactions" are mostly
force sensors, distance sensors and cameras. The focus of the research
activities shifts from the traditional industrial robotics applications
to more biomechanical "robotic devices", looking for new application
domains of the robotics signal processing and control expertise of the
research group.
Abstract:
I have been working towards a comprehensive, large-scale (and open
source) software ecosystem for robot control, on the basis of (i) the
concepts and standards of Model-Driven Engineering, and (ii) the
pragmatics of available software. In this talk, I will present my
expectations of how MDE will be able to realize such ambitious software
projects, as well as my "lessons learned" in this context.

Ichiro Nakano
(Executive Officer, General Manager, System Development Center,
Development Division, Komatsu Ltd.)
Ichiro Nakano was born in
Tokyo in 1959 and attended Waseda University for Bachelor’s degree in
Electronics and Communication Engineering. He entered in
Komatsu, a construction and mining equipment manufacturer in Japan, in
1982 and worked as one of the first engineers who introduced
computerized control systems in construction equipment. Then he
realized the importance to introduce computer software engineering
methodologies in the control software development for higher quality
and better productivity, and studied Computer Science for M.S. at
University of California, Santa Barbara from 1989 to 1991.
Since then, he is a leading architect of computer control systems and
IT systems in Komatsu, and currently is in charge of System Development
Center in Hiratsuka city in Kanagawa.
Abstract:
Komatsu is a machine manufacturer of construction and mining equipment,
and considered as one of the time-honored experts in hydraulic and
power line control systems. Control systems have been evolved rapidly
and provide various sophisticated features on machine. Now, we consider
the evolution has reached a different phase by system integration.
Recently, Komatsu is described as not only a manufacturer of advanced
machine products, but also a new value creator based on system
integration.
I will introduce three major systems which heavily depend on system
integration technologies, and as a result they differentiate Komatsu in
the industry.
- KOMTRAX: global telematics system for construction machine.
- Autonomous Hauling System: unmanned huge mining dump truck control
system
- Hybrid Excavator: world first mass-produced hybrid construction
machine.

He graduated from the
University of Tokyo in 1974, and has master degree (Electrical
Engineering). He joined Toyota Motor corp., and was mainly
involved in the research and development of Electric and Hybrid
vehicle. His main research field is the application of power
electronics to the vehicle. Through the contribution of the development
of the Toyota Prius, and the related inventions, he received the award
of Ministry of Economy, Trade and Industry from the Japan Institute of
Invention and Innovation (2004), and also received the Technical Award
from The Japan Society of Mechanical Engineers (1998).
Abstract:
System development of Hybrid Vehicle is described, comparing with the
system engineering mothodology. Prius, the first mass production hybrid
passenger car, is described as an example. From the view point of the
Dual Vee Model which is proposed by Forsberg et al., the development
model of hybrid vehicle can be recognized as an extended model of the
Dual Vee. The management of the Prius development will also be
mentioned.
