Abstract: Nuclear knowledge had been build up continuously since the middle of the last century. After Chernobyl in 1986 the public opinion changed leading to a gradual phasing out process of nuclear energy in several Member States. During that time a trend at universities and in industry was observed of a decrease in students choosing nuclear related studies. Now the generation of senior nuclear experts is retiring. On the other hand, due to security supply and climate change issues (green house mitigation measures) receiving more importance lately, a renaissance of nuclear power is ongoing. In order to avoid a possible loss of capability and knowledge in the EU action is taken now preserving and disseminating it to the new generation. There is a huge amount of information and knowledge available, either published or easily available, but also publications difficult to trace. Especially those are at risk of being dispersed or lost due to a series of factors, including: - retirement of Senior Experts who were present at the time when most Nuclear Power Plants were designed and put into operation, - generational gap (due to years of decline in new constructions, only a limited number of people started their career in that area) - non-electronic publishing in the past - limited dissemination possibilities - language (many non-English publications from Eastern countries) Therefore, the Institute for Energy of the Directorate General Joint Research Centre has developed a method for consolidation of nuclear knowledge. The method relays on the mobilisation of all identified leading experts in the EU in re-evaluating old knowledge and consolidating what is necessary to create training materials for the new generations. The methodology is applied for the second time for the present pilot study for consolidating and preserving WWER RPV safety related literature, which is part of a wider Nuclear Knowledge Preservation and Consolidation activity in the Nuclear Design Safety unit of the Institute for Energy. The WWER type reactors were widely built and used, mainly throughout Russia and the Eastern European countries. The WWER RPV was chosen due to the urgency regarding loss of knowledge and due to the proactive attitude of the involved experts and scientists. Several reviewers received between 10-100 papers in their field of expertise, in order to review the content and present it for discussion and consolidation to the WWER Reactor Pressure Vessel embrittlement experts during the workshop. The reports and presentations were requested to follow the below structure: - per paper - paper title, author(s), reference - reviewers summary/abstract - comments on "up-to-date-ness" of the papers/material - conclusion on the complete review: - more reference papers in the area known to the reviewer - open issues in the area known to the reviewer The short-term scope is to reach a consolidated conclusion for the individual reviews, after the discussion and consolidation process during the workshop. The medium-term scope is a consolidated review in the individual expert fields. The long-term scope is to prepare a State-of-the-Art report for the complete WWER RPV Irradiation Embrittlement expert field, incl. the history and reasons of the choices made (material, composition, etc.). The last general document was produced more than 26 years ago by Nikolaev, Amaev and Alechenko, which is in Russian and needs upgrading.
