The tests conducted were primarily concerned with heat transfer through zirconium alloys at heat fluxes of 500,000 Btu/(hr)(ft/sup 2/), and the effect of corrosion films on the over-all heat transfer coefficient. The decrease in the over-all heat transfer coefficients resulting from the corrosion films on most Zircaloy plates tested was less than 5% with a maximum of 11%. The conditions under which the corrosion film is formed affects the change in over-all heat transfer. Test reproducibility was within = 5%. From a statistical analysis of the results, two constauts have been derived with which surface temperature increases or changes in the over-all heat transfer coefficient due to corrosion films produced by either 680 deg F water or 750 deg F steam can be predicted. The over-all heat transfer coefficients after corrosion can be predicted as accurately as the over-all heat transfer coefficient of ''new'' Zircaloy plates. (auth)
