Adjustment methods are well known for the determination of a multigroup spectrum from foils activity measurements and have been included for many years in ASTM standards. These inversion methods combine information from activity measurements of foils with their respective response functions (cross sections and covariances) to provide a best-estimate multigroup spectrum. According to theselected method, one should provide an optional prior spectrum as input. An adjustment library CALMAR has been developed and some aspects of the library has already been exposed, this paper focusses on the public release of the library. It describes the ECORCES module for nuclear data preparation and CALMAR module for the adjustment procedure. Short samples of validation are shown.

Sledovani zatěže konstrukcnich casti reaktorových systemů neutronovým zařenim je zasadnim parametrem dozimetrie reaktoru. Neutronove spektrum v konstrukcnich castech systemů lehkých vodnich reaktorů je modifikovano vodou a železem, zatimco spektrum v reaktorových systemech (MSR / FHR) je posunuto fluoridovými solemi a grafitem. Větsina komercnich jaderných elektraren jsou lehke vodni reaktory, kde byly neutronove spektra mnohokrat prozkoumany. V připadě progresivnich technologii jako MSR / FHR se neutronove spektrum měři jen zřidka. Proto byla v reaktoru LR-0 provedena řada experimentů s rychlým dvouparametrickým spektrometrickým systemem za ucelem analýzy vlivu grafitu a fluoridů na neutronove spektrum.
