 Storage of Thermal-Reactor Safety Analysis Data (STRESA)

The STRESA information platform has been developed at the European Commission Joint Research Centre (Annunziato, 2001). It has the following main features:

  • the database is accessed via Internet
  • access to the data is controlled
  • access authorization to specific documents is performed locally by responsible of data
  • the data can be stored in various servers across the network
  • on-line visualization of data is available

STRESA is a general-purpose database to store documents and data coming from any type of plant or experimental facility as well as from code calculations. The main components of the STRESA are:

  • the data files
  • the Access database
  • the html-asp pages

The data files are stored in their original format on the computer disks: Microsoft Word files, Adobe pdf-files, AVI or MPEG video files and so on. The only exception is for the digital data files, which are stored with a method developed at JRC called WinGraf format. If the data are stored with WinGraf format it is possible to benefit of the online plotting procedure, as presented in the following figure. The plot reported here is performed on-line, on user request. The user has possibility to customize online plots to its preferences. The user interface is obtained by a series of user-friendly accessible web pages, which allow the retrieval of the information, the plotting of the experimental data point or visualization of video films and images.

One pecularity of the STRESA database is the possibility to connect various STRESA databases in order to build a complex structure of distributed database across the Internet. CRITECH maintains and develops new STRESA structure according to the needs. At the moment it is used in the SARNET Network of Excellence (Severe Accident Research) and is the supporting tool for the SKM application.
