INFORMATION ABOUT AER WG A ON IMPROVEMENT, EXTENSION AND VALIDATION OF PARAMETRIZED FEW-GROUP LIBRARIES FOR VVER 440 AND VVER 1000Pavel MikolášE-mail: pavel.mikolas@skoda-js.cz, Tel: +420 378042828 ŠKODA JS a.s., Orlík 266/15, 316 00 Plzeň, Czech RepublicABSTRACTJoint 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 fourth meeting was hosted by VÚJE, a.s. in Modra-Harmónia, Slovakia, during the period of April 18 to 20, 2016.In total 19 participants from 11 member organizations took part in the meeting and 14 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.Presentations were devoted to some aspects of transport and diffusion calculations, and especially to the benchmark dealing with VVER-440 and VVER-1000 core periphery power tilt.A. Scherenko presented paper “The ‘Full-core‘ VVER-1000 benchmark calculation by the codes included into the KASKAD code package and by the MCU code. The proposals for the benchmark specification”, Gy. Hegyi (co-authors A. Keresztúri, Cs. Maráczy and E. Temesvári) spoke about “New solution for the MIDICORE Benchmark by the KARATE code system“, I. Pós (co-authors S. Patai-Szabó and T. Parkó) added presentation “Solution of MIDICORE VVER-1000 benchmark by HELIOS code“, A. Keresztúri spoke about “Special problems of group constant generation for spectrum reactors” and finally M. Žák supplied paper entitled “Uncertainty calculation of fuel pin deflection in VVER-1000 fuel assembly”.During the meeting there were discussed the questions connected with the benchmark solutions and, among others, future activities, which are also shortly described at the end of the paper.A technical tour was also accomplished. 26th Symposium of AER on VVER Reactor Physics and Reactor Safety 1 10 – 14 October 2016, Helsinki, Finland
