Committee on the Safety of Nuclear Installations (CSNI)
The CSNI meets twice per year to
discuss nuclear safety and regulatory issues, review the work performed,
and decide on the future programme.
This programme of work is carried out mostly by working
groups. These working groups meet once or twice per year to discuss progress
and to integrate their efforts; they often rely on the work of task groups
to complete specific tasks.
Typical "products" are as follows:
- Several specialist meetings and workshops are organised
each year, addressing specific topics .
- State-of-the-Art reports and "situation reports" bring together
the latest developments in a given area or give a "snapshot picture"
of the international situation regarding a particular issue, stimulate
the formation of common understanding, and provide a source of up-to-date
information for those countries that may not have an activity in the
- International Standard Problems (ISP) are comparative
exercises in which predictions of different computer codes for a given
physical problem are compared with each other or with the results
of a carefully controlled experimental study. The main goal of ISP
exercises is to increase confidence in the validity and accuracy of
tools which are used in assessing the safety of nuclear installations.
- Somewhat related to the ISP programme is the establishment
of sets of experiments for use in comparing codes. Known as a Code
Validation Matrix, the results of such an extensive list of experiments
are collected and stored in the NEA Data Bank
for the purpose that they be made available to Member countries wishing
to validate relevant codes.
