INFORMATION ABOUT AER WG A ON IMPROVEMENT, EXTENSION AND VALIDATION OF PARAMETRIZED FEW-GROUP LIBRARIES FOR VVER 440 AND VVER 1000
23rd Symposium of AER on VVER Reactor Physics and Reactor Safety (2013, Štrbské Pleso, Slovakia)
Advances in spectral and core calculation methods
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 second meeting was hosted by ?KODA JS a.s. in Pilsen,
Czech Republic during the period of April 15 to 17, 2013.
In total 16 participants from 5 member organizations took part in the meeting and 11
papers were presented.
Objectives of the meeting of WG A are: Issues connected with spectral calculations
and few-groups 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 core periphery power tilt.
G. Hegyi presented paper ?Some final remark on our experience with the
APOLLO2 code?, P. Dalek (co-authors M. Bajan, P. Dalek, R. Zajac and V. Ne?as) spoke
about ?VVER-440 Fuel Assembly Optimization for Uprated Power?, L. Heraltov? provided
?Fullcore VVER-440 benchmark evaluation?, R. Zajac (co-author P. Dalek) informed
about ?Full Core Benchmark Calculations at VUJE?, E. Temesv?ri (co-authors Gy. Hegyi,
G. Hord?sy, A. Kereszt?ri and Cs. Mar?czy) presented ?Solution of the VVER-440
Benchmark by KARATE? and finaly D. Sprinzl (co-authors V. Kr?sl, P. Mikol and J.
?varn?) spoke about "?Full-core? VVER-440 benchmark calculated by MOBY-DICK
During the meeting were discussed questions connected with the benchmark solution
and, among others, future activities, which are also shortly described in the end of the paper.
