Information of AER WG A on improvement, extension and validation of parametrized few-group libraries for VVER-440 and VVER-1000
20th Symposium of AER on VVER Reactor Physics and Reactor Safety (2010, Hanasaari, Espoo, Finland)
Spectral and Core Calculations
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? nineteenth meeting was hosted by V?JE a.s. in Modra – Harm?nia
(Slovakia) during the period of 20th to 22nd April 2010.
There were present altogether 12 participants from 8 member organizations and 9
papers were presented (8 of them in written form).
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
to the benchmark dealing with VVER-1000 core periphery power tilt.
Tam?s Park? (co-authors Istv?n P?s and S?ndor Patai Szab?) described in his
presentation ?Application of Discontinuity factors in C-PORCA 7 code?, Radoslav Zajac
(co-authors Petr Dalek and Vladim?r Ne?as) spoke about ?Fast Reactor Nodalisation in
HELIOS Code?, Gabriel Farkas presented ?Calculation of Spatial Weighting Functions of
Ex-Core Neutron Detectors for VVER-440 Using Monte Carlo Approach? and Daniel
Sprinzl (co-authors V?clav Kr?sl, Pavel Mikol and Ji?? ?varn?) provided a definition of a
benchmark in ??MIDICORE? VVER-1000 core periphery power tilt benchmark proposal?.
Future activities are also shortly described in the end of the paper.
