"Life" Tests on Internally Water-Cooled Hollow Copper Conductors

Description: Tests were conducted to determine whether a time limitation exists on the use of internally water-cooled hollow copper conductors operating at densities of up to 330,000 amps/in/sup 2/. Using demineralized water, having a specific resistivity of 4 to 9 x 10/sup 6/ ohm-cm, no indication of a decrease in heat transfer coefficient as a function of time was observed. However, metallographic examination revealed that corrosion--erosion does occur at a slow rate. Using process water there was a time … more

Nonsafety loads on glass 1E power sources, revisited

Description: The supply of some nonsafety loads from class 1E power sources is allowed by industry standards (IEEE Standards 308 and 384) and by US Nuclear Regulatory Commission Regulatory Guides 1.32 and 1.75. This has been questioned as a possible source of degradation of the class 1E system, and this power deals with assessment of the effects of this practice on the reliability of the power supply for engineered safety features (ESF) systems.
