This study was undertaken to demonstrate capabilities of the pin-by-pin model used by the BARS code and to understand various effects of intra-assembly pin-by-pin representation of fuel power, bumup and temperature in calculational analysis of light water reactor rod ejection accidents (LWR REAs). Effects of pin-by-pin fuel power and bumup representation were investigated on the basis of calcul...

The aim of the present study was to design a solar reactor and analyze its performance for removal of methyl violet dye (MV) from water with titanium dioxide as the photocatalyst. The solar reactor was made up of a flat-plate colorless glass of dimensions 1000 x 750 x 4 mm. The base of the reactor was made of aluminum. Various operating parameters were studied to investigate the behavior of the...

This paper is dedicated to an experimental program focused on the evaluation of microstructure and failure mechanisms WWER 440 type nuclear reactor pressure vessel cladding made from Sv 08Kh19N10G2B stainless steel. Static fracture toughness tests performed standard precracked single edge bend specimens revealed extreme variations in values, J0.2. Fractured halves test were subject detailed fra...
