Nuclear measurement: guarantee radiation protection

Infos

3/1/2010

Thanks to its Canberra site, AREVA is world leader in the field of nuclear measurement instruments and radiation protection systems and in carrying out nuclear measurements. The goal of AREVA's offer in this field is to ensure the safety/security of nuclear installations and to guarantee the safety of persons working in the nuclear industry.

Associated documents

  • A nuclear measurement apparatus manufacturing plant in the US

    The North American Canberra site in Meriden, Connecticut (US) furnishes measurement solutions for internal security/safety, for checking fuel and for nuclear power plants generally. Among its products are leading-edge analytical instruments such as alpha/gamma spectrometers and alpha/beta/gamma counting systems.

  • Portable radionuclide analyzers

    In its range of measurement instruments and radiation protection systems, Canberra offers portable high resolution analyzers identifying radionuclides. These devices are used for security applications, emergency procedures and on-site assessments.

  • Grid chambers for spectrometry

    The LEA (Laboratoire Etalons d'Activité) of CERCA (AREVA subsidiary) is specialized in the manufacture of radioactive reference sources for industry, medicine and research. The lab employs grid chambers made by Canberra for alpha spectrometry.

  • Radiation control frames at site exits

    The Canberra site at Loches (Indre-et-Loire Département) manufactures both fixed and portable radiation protection apparatus, among which are frames for monitoring the alpha, beta and gamma rays given off by pedestrians and vehicles leaving a specific zone or site.

  • Monitoring ambient levels of radioactivity

    To ensure the safety/security of nuclear installations, Canberra proposes instruments monitoring ambient levels of radioactivity. By detecting radioactive sources or hot spots, "Handle-R" helps ensure optimum radiation protection.

Optimizing availability

For increased competitiveness, electricity producers are seeking to optimize their production tool. OneProd dedicated conditional maintenance solutions for rotating machinery (motors, pumps, etc) meet this need.

Field Report #7: Fleet Safety

Field Report #7: Fleet Safety

Experience shows that very unlikely events occur and that plant operators need efficient systems to safely shutdown their plants and to remain in control in case of an unexpectedly complex sequence of events.

Find out how AREVA is helping utilities demonstrate the safety of their nuclear fleets, while reinforcing public confidence.

Through accurately monitoring the operation of machinery and expert analysis of the collected data, the OneProd solutions:

  • Increase the availability of rotating machinery, thanks to the prevention of malfunction risks and scheduled maintenance operations.
  • Reduce maintenance costs: the maintenance service schedule is monitored and, if they are necessary, maintenance operations are only started at the most appropriate time.

The range of techniques used (vibration analysis, electrical measurement, lubricant or thermography analysis), along with the expertise of our teams, enables us to draw up comprehensive and reliable diagnostics.

Our modular offer allows us to build the most suitable solution based on our customers' needs and strategies. The guidelines relate to:

  • Deployed techniques, depending on the necessary monitoring,
  • The monitoring method, continuous or periodic, local or remote,
  • Our commitment level, which can go up to a contractual commitment to achieve results.

Improved competitiveness

  • Rotating machines more available and more reliable.
  • A safer environment: machine operation is carried out under more controlled conditions.
  • A positive financial impact from the first year: thanks to lower maintenance costs and increased production.
  • Reliable diagnostics: thanks to proven methodology and the completeness of the many techniques employed.
  • A partner committed to results, by means of appropriate contracts.

An integrated modular solution

OneProd is the integrated multitechnical, modular conditional maintenance solution for a wide area of applications.

With its web architecture, among other things, it enables the remote monitoring of machinery for greater flexibility.
