Initiated by AFCEN, CEN Workshop 64 (WS64) is the only active forum in Europe issuing recommendations on the content of nuclear codes from panel working groups.

CEN WS64 aims to :

• Create a community of European nuclear code experts
• Enable European operators to use AFCEN codes for their needs (long-term operations, spare parts, new reactors) and in their local context.

Created in 2011, CEN WS64 is in its 4th phase, which began in July 2023 and will end in mid-2027. The main drivers of this phase are :

• The results of the previous phases of the WS64 as well as significant results concerning the evolution and proposals for R&D
• The creation of a core community around nuclear codes at European level
• The need for nuclear energy in Europe, as highlighted in DG Energy's Nuclear Illustrative Programme (PINC) published in 2017
• The fight against global warming and the international context (Ukrainian crisis): nuclear power is a solution because of its low greenhouse gas emissions and its contribution to energy independence.

Open to anyone wishing to contribute, all types of stakeholders are represented, currently 15 companies have participated and 10 countries are represented (Belgium, Finland, France, Germany, Italy, Poland, Sweden, United Kingdom, Switzerland, Czech Republic as well as the EC through the JRC).

A kick of meeting for phase 04 of CEN Workshop 64 (CEN/WS 64) "Design and construction codes for GEN II to IV nuclear installations" was held on 29 June 2023 in Brussels, during which participants expressed their interests in the new phase of Workshop 64, which will run for a period of 4 years. The results of the previous phase and the prospects already identified for the new phase were also presented.

Fifty participants representing 27 different stakeholders (safety authorities and their technical support, operators, manufacturers, design offices and R&D organisations), including a dozen new participants in the workshop, attended this meeting.
