Posey, W.J. ed.

Work continued on film boiling with water inside tubes. Sodium silicate was used in combination with insulating materials to investigate its usefulness as an innibitor to chloride stress corrosion. The corrosion specimens were 1-In. Sch 40 Type 304 stainless steel pipe which were stressed, insulated and thermally cycled from approximately 200 to 650 deg F by periodic heating and emersion in sea water. Stressed, uninsulated 1-in. Sch 40 Type 304 stainless steel pipe specimens were exposed to a high humidity simulated sea water--air environanent for a 1000 hr period to investigate the occurrence of cbloride stress corrosion. The purpose of the BTF Pressurizer BIowdown Test was to obtain vessel blowdown data to establish that the specific application of the mathematical model used to describe the reactor blowdown is conservative for the size of the pressure vessel. The pressure buildup in the vapor coatainer during loss of coolant accident in a reactor is being studied. The reaction rates of sodium sulfite and dissolved oxygen in boiler water and feed water are being studied as a function of temperatare, oxygen concentration, sulfite cencentration, phosphate conceatration, pH, and copper concentaration. Potassium pentaborate is being considered as a chemical poison to reactor shutdown. (For preceding period see MSAR-59-89.) (W.L.H.)
