Popis: A r t i c l e s [2-6] p ropose var ious l imi ta t ions on the heat exchange, which a r e de t e rmined in the main by the heat r e s i s t a n c e of the fuel p a r t i c l e s . The approach to the p rob lem of de te rmin ing the effect of the r e s u l tant sodium vapor on the p roces s v a r i e s . It is sugges ted that the vapor envelopes the fuel fully, a f te r which the t r a n s m i s s i o n of heat f rom the fuel to the coolant can be ignored [2], or that a f i lm of sodium r e m a ins on the su r face of the fuel pa r t i c l e s f rom which it a l so evapora te s [3-5]. These models d e s c r i b e the boundary ea ses of the p roce s s of heat t r a n s m i s s i o n . A r t i c l e [6] sugges ts what appea r s to be the most r e a l i s t i c model, which takes into account the poss ib i l i ty of the fo rmat ion of a th in vapor f i lm on the su r face of the fuel p a r t i c les having finite heat r e s i s t a n c e . The fo rmat ion of such a f i lm has been conf i rmed expe r imen ta l ly [7, 8].
