InquiryThis occurs as the temperature of the fuel cladding surface increases so that the surface of the metal was too hot surface dries out for nucleation boiling. When the surface dries out the rate of heat transfer decreases, after a further increase in the temperature of the metal surface the boiling resumes but it is now film boiling .
