Information about AER WG A on improvement, extension and validation of parametrized few-group libraries for VVER 440 and VVER 1000
21st Symposium of AER on VVER Reactor Physics and Reactor Safety (2011, Dresden, Germany)
Spectral and core calculations
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? twentieth meeting was hosted by ?KODA JS a.s. in Plze? (Czech
Republic) during the period of 9th to 11th May 2011.
In total 19 participants from 7 member organizations were present 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
also benchmarks dealing with VVER-1000 and VVER-440 core periphery power tilt.
Zs. Sz?cs?nyi (co-author I. Nemes) presented ?Investigation of highly enriched fuel
for VVER-440 application using different geometry and enrichment profile?, R. Zajac (coauthors P. Dalek, C. Strmensk? and J. Majerk) spoke about ?VVER-440 with IMF Safety
Analysis of Control Rod Ejection?, G. Hord?sy (co-authors Gy. Hegyi, Cs. Mar?czy and E.
Temesv?ri) presented paper called ?Preliminary Solution of the ?MIDICORE? VVER-1000
Core Periphery Power Distribution Benchmark by KARATE and MCNP?, P. Dalek (coauthors M. Antal and D. Bun?ek) spoke about ?First utilization of GD2 fuel with enrichment
4,87% at SE-EBO?, P. Mikol (co-author P. Vesel?) presented paper called ?VVER-440
Fuel Cycles with Increased Enrichment and Uranium Mass? and D. Sprinzl (co-authors V.
Kr?sl, P. Mikol?? and J. ?varn?) provided a ?Full-Core? VVER-440 pin power distribution
calculation benchmark proposal?.
Future activities are also shortly described in the end of the paper.
