The ISOE European Technical Centre (CEPN) is conducting a survey on the precautionary measures implemented by the nuclear utilities to reduce the risk of transmission of the Covid-19 coronavirus and their impact on radiation protection management and practices.

The answers are made available on this restricted area of the ISOE website according to the usual rules, i.e. available for all ISOE Members (Utilities and Authorities) or for Utilities only according to the decision of each responder.

If you would like to contribute, please Download the questionnaire  and send the document to the following address: isoe@cepn.asso.fr

The ISOE 2 Database is composed of ISOE 2 Static and ISOE 2 Dynamic questionnaires.
The ISOE 2 questionnaire data were collected for the first time in 2003.  

However, due to the small number of questionnaires available in the database, the ISOE Management Board decided in 2011 to stop data collection and to keep existing questionnaires as pdf files on the RP library of ISOE Network.

These Operating Experience (OpEx) reports provide plant information on good practices in Radiation Protection (RP) or situations involving unusual RP Problems

EDF and EPRI have started a multi-year program to optimize Reactor Cavity Decontamination. EDF is focused on improving the cavity decontamination process performed during outages in the French PWRs and in parallel, improvements to the decontamination processes of circuits (systems) and of big components will also be investigated. In order to maximize resources and provide benefit to all EPRI members, EPRI and EDF will be collaborating, as much as possible, on this optimization project. Special emphasis will be placed on collecting international experience on this subject.

To facilitate the collection of international experiences, series of international workshops in France or the USA will be organised.

Survey

A survey has been made in April 2013 within the ISOE European Utilities and US EPRI members to collect information on:

1. Reactor cavity characteristics
2. Reactor cavity access
3. Reactor cavity decontamination
4. Duration, Schedule and Labor
5. Reactor Cavity Decontamination Method
6. Reactor Cavity Decontamination Strategy
7. Decontamination Extent
8. Radiation protection issues
9. Personnel and System Safety Considerations
10. Feedback Experience
11. Pending or proposed modifications to improve the process
12. Chemical decontamination processes for systems or components
13. Additional relevant information not addressed within the Survey

The synthesis of the answers to this survey can be Folder downloaded here .

If you would like to participation to this exchange of information, please complete and return the following document (see below in Documents section) to EPRI, EDF and ISOE.

Workshop

The first EDF-EPRI International Workshop has been organised by EDF in Paris (France) on 25 and 26 September 2013.

 The Proceedings are available here (restricted to Utilities only)

This section provides you with the syntheses of the requests posted on the ISOE RP Forum grouped by topics and taking into account their restrictions: ISOE Members or Utilities Only.

Only requests with more than 5 answers are provided.

This section has been created after the Fukushima NPP Accident due to the earthquake/tsunami on 11 March 2011.
