New consortium to address industry need for nuclear heat and power
Hoping to tackle a growing global demand for energy, The Open Group, a vendor-neutral technology and standards membership organization, has announced the formation of the Industrial Advanced Nuclear Consortium (IANC) to collaborate on finding advanced nuclear energy solutions to serve industrial customers.

The effects of internal circulation velocity and the presence of noncondensable gas on vapor removal rate by condensation from a rising large vapor-gas bubble produced in a hypothetical core disruptive accident are investigated by solving the resulting transient heat and mass transfer problem of turbulent flow. Sample calculations are performed for the condensation of UO2 and sodium vapors containing noncondensable fission gases. The time-averaged condensation heat transfer coefficients are presented for the condensation of UO2 and sodium vapors for different internal circulation velocities and the concentration of noncondensable gas.
