Introduzione alla RV
DEFINIZIONI
•La realtà virtuale (VR O RV) è una tecnologia
che consente di ricreare, tramite computer,
mondi e oggetti che sono la trasposizione
digitale di ambienti reali o di fantasia.
•RV è un modo per visualizzare, manipolare e
interagire con dati estremamente complessi
per mezzo di una simulazione che, in ambienti
immersivi, viene percepita totalmente dai nostri
sensi, in particolare dalla vista, seguita
dall’udito e dal tatto.

PECULIARITA’
Differenze con la grafica tradizionale (CAD)
• Utente sceglie
• Interazione
• Realismo (rendering: resa realistica degli
oggetti rappresentati, real-time)
• Immersività, senso di presenza (I/O
video/audio)
• Cooperazione (Telepresenza)

Why Use VR in CRE?

Costly physical mock-up not necessary
 Design
can be modified quickly and easily
to prototype different solutions in a short
period of time


© IFE Halden VRC
Can evaluate a design against ergonomic
data, guidelines and recommendations
Save time and money in addition to a more
optimal design solution

Fugen Nuclear Power Station

KYOTO



The Fugen reactor is
situated in Fukui, in the
centre-western part of
Japan. (one hour by train
from Kyoto)
Fugen is a 165MWe,
heavy water moderated,
light-water cooled
pressure-tube type reactor.
It went into commercial
operation in 1979.
Decommissioning will
start March 2003, and will
take about 20 years.

Each worker also has
Scenarios
a name and a
description that can be
edited by the user.
In a Scenario one or
more manikin workers
perform work tasks
inside the NPP.

In order to distinguish
between workers,
each gets a different
colouring either on
the suit or the helmet.

Visualisation
A surface plot of the
dose-rate in the area
around the spectator is
also provided.
The data in this plot are
measurement
interpolations at the
chest (dosimeter) height
of a person viewing the

Scenario Recording
A scenario is recorded as a
set of routes with action
markers. Each of these
routes or work tasks
belongs to a manikin.
© IFE Halden VRC
[email protected]
Le attività di Halden - VR-Dose
Playback of Scenarios
The manikin is also
pausing on markers where
it has been synchronized to
wait for other manikins to
finish their tasks.
On playback the manikin will
walk the route as recorded, doing
work or handling objects on the
markers where the user has
recorded such actions.

The Dose-Rate of a Work Task
In the scenario recording, routes with
markers of positions and duration at each
position are generated.
These routes may
afterwards be assigned to
real life workers from the
system worker database.

Libreria di oggetti

A bank of decommissioning tools is
being made. These tools can be
inserted into the Fugen model and
used by the manikins in the
scenarios.

In a dismantling process, cutting of
various large objects will be
necessary. This is a complicated task
in VR, and a module for cutting pipes
is being made this year.


A more user friendly interface is
under development.

In the decommissioning project, JNC
will use the planning and work
estimation system “COSMARD” by
JAERI. The new user interface of
VRdose will try to reflect the
COSMARD work breakdown.

Based on COSMARD, a wizard for
scenario recording will help the user
to enter information into the system.
