The input model was developed by strictly following the recommendations on noding and the use of the default parameters provided in the ISP-46 Specification Report. Special attention was given to the modelling of the specifics of the Phebus facility. A comparison of the simulation results and the experimental measurements showed good agreement for the thermal-hydraulic variables and satisfactory agreement for the total releases for most radio-nuclides, whereas the radio-nuclide depositions in the steam generator were overestimated. The timing of the key events was relatively wellpredicted. The differences between the simulation results of both MELCOR versions were negligible for the thermal-hydraulic variables, small for the radio-nuclide releases and the timing of the key events, but significant for the radio-nuclide depositions and the bundle degradation. In general, the results of the newer MELCOR 1.8.5 version RE show better agreement with the experimental measurements"},{"@xml:lang":"sl","#text":"V okviru sodelovanja v Mednarodnem standardnem problemu OECD st. 46 smo z dvema verzijama programa MELCOR 1.8.5 (QZ in RE) simulirali ključne pojave v gorivnem svežnju in primarnem krogu naprave Phebus med fazo degradacije sredice pri preizkusu Phebus FPT1. Pri razvoju vhodnega modela smo upoštevali priporočila glede nodalizacije in uporabe privzetih parametrov, ki so podana vspecifikacijah ISP-46. Posebno pozornost smo namenili modeliranju specifičnosti naprave Phebus. Primerjava rezultatov izračunov s preizkusnimi meritvami je pokazala dobro ujemanje termohidravličnih spremenljivk in zadovoljivo ujemanje končnih izpustov za večino radioaktovnih snovi, medtem koje odlaganje v uparjalniku precenjeno.

Razlike med rezultati simuliranj z obema različicama programa MELCOR so zanemarljive za termohidravlične spremenljivke, majhne za izpuste radioaktovnih snovi in časovno napoved ključnih dogodkov, vendar pomembne za odlaganje radioaktovnih snovi in degradacijo sredice.
