HRT PRESSURE VESSEL TEMPERATURES DURING OPERATION--AN EVALUATION USING DATA FROM RUN 16

PDF Version Also Available for Download.

Description

A study was made of the data taken during HRT Run 16, concerning the temperatures and thermal stresses in the pressure vessel. By making heat balances across the blast shield cooling coils, the pressure vessel cooling system was shown to be performing satisfactorily. Estimates of the thermal stress in the pressure vessel wall show values which range from 1800 psi it low power to 6800 psi at 5 Mw. The thermal stress does not appear to be excessive in this power range. The over-all heat generation in the pressure vessel was estimated to be 108,000 Btu/hr.Mw. By comparing the heat ... continued below

Description

A study was made of the data taken during HRT Run 16, concerning the temperatures and thermal stresses in the pressure vessel. By making heat balances across the blast shield cooling coils, the pressure vessel cooling system was shown to be performing satisfactorily. Estimates of the thermal stress in the pressure vessel wall show values which range from 1800 psi it low power to 6800 psi at 5 Mw. The thermal stress does not appear to be excessive in this power range. The over-all heat generation in the pressure vessel was estimated to be 108,000 Btu/hr.Mw. By comparing the heat flux at the inside surface of the pressure vessel with the temperature drop across the blanket solution film, which would be required to force compliance with the theoretical equations, a heat transfer film coefficient at this surface may be estimated. A rough correlation between this film coefficient and the temperature drop across the film indicates that heat is being tranmitted principally by natural convection. It is recommended that a complete temperature profile be attempted on the replacement reactor prossure vessel. If this cannot be done, then provision for thc measurement of the inside surface temperature should be made. (auth)
