NUCLEAR SAFETY IMPROVEMENT LEVELS
The domain of Nuclear Integrated Safety Management is the whole life cycle of nuclear energy production and
resources management. It includes: design, exploitation and decommissioning phases, as well as the policy
making. All of them require a common systemic meta-modeling framework.
A. General look on the improvement strategy of the integrated nuclear safety in a local and large-
scale (the TOGA classification criteria applied) :
- new or modified physical & technological nuclear processes for energy production
- new or modified control process (employed optimization and computer technologies)
- new control & supervising technologies (new sensors and computer technologies)
- new control & supervising strategies ( operatore's console system and human-organization efficacy).
- new decision and policy making strategies (modeling of socio-cognitive infrastructures and
cultural strategies implemented in new Intelligent Consoles as an active/Intelligent Decision Support
Systems (IDSS) Network.
B. Vulnerability of Human, Organization, Socio-Economical and Cultural Factors require
an intelligent support and substitution of plant operators and managers in well defined
decision-making tasks, such as precautionary decisions, risk mitigation and procedural
emergency management .
Human vulnerability levels relate to:
1. Operator level
plant operator - computer interactions (improvements: training and technologies for human-computer
- operator decisions (improvements: training and IDSS - Intelligent Decision Support Systems)
- operator - organization interactions (improvements: training and IDSS - Intelligent Decision Support
2. Organization level
- managerial and organization decisions (improvements: models development, identification, training and
IDSS - Intelligent Decision Support Systems for management).
3. Policy and Social Level
- strategic policy makers - influence and coordination (improvements: theory and models development,
identification, training and IDSS - Intelligent Decision Support Systems for policy making).
- public opinion - politics (improvements: systemic cause-consequences models, technical information
dissemination, human-friendly distributed network of IIS- Intelligent Information Systems).

POSSIBLE SOLUTIONS IN SHORT and MIDDLE TERMS
An Integrated Intelligent Supervisory and Embedded Intelligent Infrastructure Network
It means, the development of networked:
Super-safety Universal Intelligent Console
for multi-role supervision, control, and management
Applying TOGA (Top-down Object-based Goal-oriented Approach), we distinguish 4 main layers
of safety building and the problem/goal dependent points of view (see also):
- Problem/goal dependent points of view /(modeling perspectives) , examples: safety for plants,
safety airplane, safety for a society. In general, goal dependent points of view are either a set of
conditions which are requested for the safety of an object/system X, or a set of conditions which has to
enable to achieve a safety level for a preselected object/system/material/process in a domain D.
Here, in the natural safety layer (1), the first processes which has to be investigated and assessed are
process-components of the nonlinear dynamics of the reactor core. This field has been the domain of
multi-year ENEA research. In other words, the operator has to know which are the critical processes,
their indicators, and efficacy of control variables, see also (*).
cooperating with human resources (operators, managers). It is an essential component of integrated
models of super-safety for the management of nuclear plants.
We should remember that only sufficiently precise models of human and organization decision-
making may enable to recognize its weak points, to simulate it, and to elaborate effective
defense and protection strategies, as well as to design a network of intelligent decision support
- They all together are necessary for nuclear super-safety integrated management.
