28. Operational and maintenance (for example weld
inspection management)
It's easy to access all engineering
information and inspection's data
through 3D model.
There are very important sources of
information that require constant
monitoring for NPP safety operation:
weld conditions for tanks, radioactive
drain headers, pipelines and other high-
pressure equipment.
IMS based on 3D engineering model is a
very powerful tool for collecting, storing
and providing an intuitive access to all
operational data.
On this slide you can see the result of
automatic indication NPP welds based on
operational data:
• green - an inspection was done,
normal condition
• orange – missing inspection more
than 3 days
• red – missing inspection more than 10
days.

On this 3D model you can see
turbine island part
There is color marked information
about equipment state, that was
receive from inspections
34. Fire evacuation routes modelling:
The room, where we have troubles,
marked red (information was
automatically receive from instruments)
Nearest rooms, where personnel works
are marked blue.
Evacuation route that personal should
use is marked green.
We can quickly get information about
every room: fire resistance
characteristics, fire-fighting equipment,
etc.
This visualization helps to get all
information for decision to eliminate fire
and personal evacuation.

44. The applied technologies:
Laser scanning
The main characteristics
Accuracy: from 1 мм
Range: to 2500 м
Scanning time: 2-3 min
Quantity of points: to several million
Laser scanning is a technology providing a people-independent way of obtaining actual reliable topological
information about a condition of an object within shares of millimeter.
It is active applied since the end of the 90th years in such branches as oil and gas industry and metallurgy
when collecting initial information to carrying out modernization and reconstruction of productions.
It was initially developed in France in the late eighties for recovery of documentation to nuclear objects.

Based on all this data about equipment, piping,
structure and others the following calculation can be
done:
• radioactive waste volume according to
categories: high-level, middle-level and low-
level radioactive waste.
• radioactive decontaminant volume and liquid
radioactive waste volume.
• radioactive waste volume specifications.
