Abstract

Joint AER Working Group A on „Improvement, extension and validation of parameterized few-group libraries for VVER-440 and VVER-1000“ and AER Working Group B on „Core design“ twenty sixth meeting was hosted by VÚJE, a.s. in Modra – Harmónia, Slovakia, during the period of April 23 to 25, 2018.

In total 17 participants from 10 member organizations took part in the meeting and 12 papers were presented. Objectives of the meeting of WG A are: Issues connected with spectral calculations and few-group libraries preparation, their accuracy and validation. The presentations were devoted to some aspects of transport and diffusion calculations, libraries preparation, and to the benchmarks dealing with VVER-440 and VVER-1000 core periphery power tilt.

In frame of WG A: Y.P. Kalinin (co-authors S.S. Aleshin and D.S. Oleynik) presented paper “First experience of solving “’Full-Core VVER-440 RK3+ BENCHMARK’ by KASKAD program package”, P. Mikoláš (co-authors J. Vimpel, D. Sprinzl and S.S. Aleshin) spoke about “Full-Core-RK3+ benchmark“, A. Keresztúri (co-authors I. Pataki and B. Batki) discussed “Application of DFs for the VVER-1000 MIDICORE benchmark”, D. Sprinzl (co-author J. Závorka) added presentation “Full-Core VVER-1000 calculation benchmark“, J. Bajgl (co-author M. Bárta) showed “Some Remarks to the Subcriticality Calculation by MOBYDICK Code” and finally P. Dařílek supplied presentation “HELIOS validation at fast spectrum”.

During the meeting there were discussed the questions connected with the benchmarks solutions and, among others, future activities, which are also shortly described at the end of the paper.
